The rhabdoid variant of adrenocortical carcinoma-Report of three cases and literature review

Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Extensive rhabdoid morphology in ACC has been described recently in very few cases. The proportion of rhabdoid morphology and the role of SMARCB1/ INI1 expression in these tumor cells to diagnose the specific variant is not described in the literature. We reviewed the clinicopathological features of nine cases of adrenocortical neoplasm. Out of which, three cases of ACC showed predominant rhabdoid morphology. Large discohesive cells with abundant cytoplasm containing eosinophilic inclusions, eccentric vesicular nucleus, and prominent nucleoli. INI1 immunostain was retained in all cases. We reported the rhabdoid variant of ACC, a novel entity, and its diagnostic approach from their histological mimickers. Identifying more cases of this entity will help to clearly understand the pathogenesis, biologic behaviour, and any specific molecular alterations in the future.

Aldosterone and cortisol-secreting adrenocortical carcinoma: a 10-year follow-up case report and literature review / 中华内分泌代谢杂志

A 10-year follow-up case of aldosterone and cortisol-secreting adrenocortical carcinoma, a rare disease presenting as an adrenal space-occupying lesion accompanied with hypertension and hypokalemia was reported, and the medical record was investigated in detail. Through case presentation and literature review, it was noted that patients with adrenocortical carcinoma presented a difference in clinical manifestations, pathology, and biological behaviors. This paper may help clinicians enhance their understanding of adrenocortical carcinoma. Especially significant adrenal space-occupying lesions highly suspicious of recurrence and producing different types of endocrine hormones should be paid more attention.

Surgical strategy and procedure of adrenocortical carcinoma with retrohepatic inferior vena cava tumor thrombus with intraoperative ultrasound guidance / 中华肝胆外科杂志

Adrenocortical carcinoma (ACC) with inferior vena cava thrombosis is rare and has a poor prognosis, and the current literature overwhelmingly supports aggressive surgical intervention. This article summarizes the management of a patient with ACC with inferior vena cava thrombosis, and discusses the feasibility of detailed preoperative imaging data and intraoperative ultrasound to assess the superior and inferior boundaries of ACC with inferior vena cava thrombosis, while describing the intraoperative ultrasound-guided surgical planning and procedure for ACC with retrohepatic inferior vena cava tumor thrombus. Furthermore, it also demonstrates that it is feasible to accurately assess the superior and inferior boundaries of ACC with inferior vena cava thrombosis by preoperative multimodal imaging and intraoperative ultrasound, determine the mode of flow blockage during the operation, and obtain radical resection of the tumor.

Carcinoma corticosuprarrenal virilizante en un niño / Virilizing adrenocortical carcinoma in a child

Introducción: Los tumores suprarrenales en niños son poco frecuentes y el carcinoma suprarrenal representa menos de un 10 %. En el prepúber, la manifestación más típica es el desarrollo de pubertad precoz. Objetivo: Describir las características clínicas, los procederes diagnósticos y terapéuticos de un paciente con carcinoma adrenal en edad pediátrica. Presentación de caso: Paciente de 8 años, masculino y de piel blanca con antecedentes de salud. Acude a la consulta por crecimiento de vello pubiano y aumento del pene en longitud y grosor de aproximadamente 2 años de evolución. En el examen físico se constatan aumento de la velocidad de crecimiento y signos sugestivos de virilización (voz gruesa, vello axilar, vello sexual púbico y genitales externos estadio III de Tanner). Se realizaron estudios hormonales que corroboraron el hiperandrogenismo por secreción endógena autónoma, con niveles de gonadotropinas suprimidas, niveles de testosterona y dehidroepiandrosterona elevados. También se realizaron estudios imagenológicos que evidenciaron edad ósea acelerada y la existencia de un tumor. Se realizó una adrenalectomía izquierda y se confirmó por anatomía patológica el carcinoma corticosuprarrenal virilizante izquierdo en estadío 2. Inició un tratamiento con quimioterapia por dicho diagnóstico y actualmente se mantiene en seguimiento. Conclusiones: Los carcinomas corticosuprarrenales en niños son mayoritariamente funcionantes y constituyen una de las causas de pubertad precoz periférica. Estos son infrecuentes y agresivos, por lo que la realización de estudios genéticos en familias con síndromes hereditarios contribuiría a su diagnóstico precoz para un adecuado tratamiento y mejor pronóstico(AU)

Introduction: Adrenal tumors in children are rare and adrenal carcinoma represents less than the 10 percent. In the prepubescent, the most typical manifestation is the development of early puberty. Objective: Describe the clinical characteristics and diagnostic and therapeutic procedures of a patient with adrenal carcinoma in a pediatric age. Case presentation: 8-year-old male, white-skinned patient with a history of health conditions. He attentds to the consultation due to pubic hair growth and penis enlargement in length and thickness of approximately 2 years of evolution. Physical examination shows increased growth rate and signs suggestive to virilization (deep voice, axillary hair, pubic sexual hair and external genitalia in Tanner's stage III). Hormonal studies were carried out that corroborated hyperandrogenism by autonomic endogenous secretion, with suppressed gonadotropin levels, elevated testosterone and dehydroepiandrosterone levels. Imaging studies were also performed that showed accelerated bone age and the existence of a tumor. A left adrenalectomy was performed and stage 2 left virilizing adrenocrotical carcinoma was confirmed by pathological anatomy studies. He began chemotherapy treatment for this diagnosis and is currently being followed up. Conclusions: Adrenocortical carcinomas in children are mostly functioning and are one of the causes of peripheral early puberty. These are uncommon and aggressive, so genetic studies in families with hereditary syndromes would contribute to their early diagnosis for adequate treatment and better prognosis(AU)

Carcinoma de corteza suprarrenal. Presentación de un caso y revisión de la literatura

RESUMEN El carcinoma suprarrenal es un tumor raro pero devastador, esto se debe fundamentalmente a que en la mayoría de los casos se encuentra en estadios avanzados en el momento del diagnóstico. Tiene una incidencia de 0,5-2 casos por un millón habitantes al año. Entre el 40 y el 70 % de los pacientes tienen metástasis cuando se inicia el estudio. Se presenta de manera general en adultos, aunque también afecta a los niños. La mediana de edad en el momento del diagnóstico es 46 años, siendo más frecuente en el sexo masculino. Se presenta el caso de una paciente con antecedentes de hipertensión arterial de un año de evolución, ante los síntomas presentados se le realizan estudios por imágenes y de laboratorio diagnosticándose un tumor suprarrenal izquierdo. Se le realizó supraadrenalectomía izquierda obteniéndose como resultado histopatológico un carcinoma adenocortical suprarrenal. Se presenta este caso porque el carcinoma suprarrenal representa una entidad poco frecuente y es relevante exponer esta experiencia para el manejo de este tipo de neoplasia.

ABSTRACT Adrenal carcinoma is a rare devastating tumor, mainly because in most cases it is in advanced stages at the time of diagnosis. It has an incidence of 0.5-2 cases per one million inhabitants per year, in which 40 to 70 % of patients have metastases when the study begins. It occurs mainly in adults, although it also affects children. The median age at the time of diagnosis is 46 years, being more frequent in males. The case of a patient with a history of arterial hypertension of one year of evolution is presented. In view of the symptoms presented, imaging and laboratory studies are performed, diagnosing a left adrenal tumor. A left supraadrenelectomy was performed, obtaining an adenocortical adrenal carcinoma as a histopathological result.

Giant virilising adrenal cortical carcinoma

Androgen secreting adrenocortical carcinoma (ACC) is a very rare disease with a poor prognosis. Approximately 80% of tumors are functional, most commonly secreting glucocorticoids. We herewith report a case of a huge functional ACC of the right adrenal gland in a 33-year-old female who presented with complaints of hirsutism, amenorrhea and an abdominal lump. On abdominal examination a large lump was palpable in the right hypochondrium reaching up to the umbilicus. Contrast-enhance computed tomography (CECT) revealed a mass in the right suprarenal region. The tumor measured 29 cm × 20 cm × 12 cm and weighed 7.8 kg, the largest reported case of ACC in the world to the best of our knowledge.

Construction and verification of tumor microenvironment-related gene prognostic model for adrenocortical carcinoma / 肿瘤研究与临床

Objective:Bioinformatics method was used to screen out prognostic model constructed by the tumor microenvironment (TME)- related genes of adrenocortical carcinoma (ACC), and the prognostic model was verified to provide clinical guidances and related biomarkers for the diagnosis and treatment of ACC.Methods:Transcriptome and clinicopathological data of 79 ACC patients were collected from the Cancer Genome Atlas (TCGA) database. ESTIMATE algorithm was used to calculate immune score, stromal score (both reflect TME) and ESTIMATE score; VennDiagram was used to select differentially expressed genes among immune score, high and low stromal score groups (grouped by median value); Gene Ontology (GO) database and Kyoto Encyclopedia of Genes and Genome (KEGG) database were used to perform functional enrichment analysis on selected genes and to explore the potential function and pathway of genes. Univariate Cox analysis, lasso regression analysis and multivariate Cox analysis were used to screen out genes related to ACC TME and to establish risk score (RS) model for ACC patients. The receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of RS. The data sets GSE33371 and GSE19750 of Gene Expression Omnibus (GEO) were used as external validation sets to validate the prognostic model. The data of 79 ACC patients were extracted from the TCGA database, and the clinicopathological factors and the RS of the established prognostic model were included in the Cox regression analysis to obtain the prognostic factors of ACC patients.Results:According to the immune score and stromal score, 1 205 differentially expressed genes from intersection of both scores were screened out by using VennDiagram, including 833 up-regulated genes and 372 down-regulated genes. After continuing the regression analysis and screening of differentially expressed genes, the ACC prognostic model containing 9 TME-related genes (GREB1, POU4F1, HIC1, HOXC9, CACNB2, RAB27B, ZIC2, C3, CYP2D6) was finally constructed, that was, RS = GREB1×0.223 6+POU4F1×0.671 7+HIC1×0.167 5+HOXC9×0.211 3+CACNB2×0.156 0+RAB27B×0.956 5+ZIC2×0.582 7+C3×(-0.003 1)+CYP2D6×0.819 3. The area under the curve (AUC) of ROC for the 1, 3, and 5-year overall survival of 79 ACC patients predicted by the model in the TCGA database was 0.876, 0.919, 0.917, respectively. In the GEO validation set, the AUC of the 1, 3, and 5-year overall survival for 45 ACC patients predicted by the model was 0.689, 0.704, and 0.708, respectively, indicating that the model had a high prediction accuracy for survival results of ACC patients. Cox regression analysis on the data of 79 ACC patients in the TCGA database showed that the TME-related gene prognostic model RS was an independent factor influencing the prognosis of ACC patients ( HR = 1.011, 95% CI 1.005-1.016, P < 0.01). Conclusions:The established ACC TME-related gene prognostic model can be used to predict the prognosis of ACC patients. The model including 9 genes may become a new target for studying the pathogenesis and immunotherapy of ACC, and it is worthy of further research.

Giant non-functioning adrenocortical carcinoma: an unusual tumour presentation

Adrenocortical carcinoma is a rare tumour with incidence of 1 per million all over the world. Age distribution is bimodal with peaks occurring at 5-20 years and 40-50 years. Tumours greater than 9 cm commonly involve inferior vena cava (IVC) or right side of heart. 80 percent of the carcinomas are functional. We describe a case report of a rare tumour of a non-functioning adrenocortical carcinoma in a 40 year old female having incidence of 0.5/million world over with no extra-adrenal spread at presentation without IVC or right heart involvement in spite of having a large size of 12 cm. Patient underwent successful surgical extirpation with adjuvant radiotherapy with regular follow ups and disease free survival since the surgery. It is imperative to determine hormone levels in symptomatic and asymptomatic patients with adrenal masses. The possibility of adrenocortical carcinoma should not be ruled out in a functioning/non-functioning tumour. All solid incidentalomas on computed tomography (CT)/magnetic resonance imaging (MRI) greater than 5 cm in size should be removed surgically with adjuvant therapy consideration after histopathological reporting.

Functioning adrenocortical carcinoma causing virilisation: a case report

Adrenocortical carticnoma (ACC) is an uncommon tumor with an incidence of 1-2 cases/million/year. It has two peak incidences; the first one in the first decade and the second one in the fourth decade. Most patients present with features of steroid hormone excess or abdominal mass effects, but about 15% of ACC are diagnosed incidentally. It is hormonally functional in 80 - 100% patients and the predisposing lesions include congenital adrenal hyperplasia and adenoma. ACC has significant syndromic and genetic association. Surgery offers the best chance of cure, especially in localized disease. Here, we present the case of virilization in a young female child secondary to a functioning ACC. The child had classical hormonal and imaging features of functioning ACC and underwent resection of the tumor (Adrenalectomy) with good outcome.

Clinical features and imaging findings of adrenocortical carcinoma in children / 中国医学影像技术

Objective: To observe clinical features and imaging findings of children adrenocortical carcinoma (ACC). Methods: Clinical and imaging data of 13 children with ACC confirmed by pathology were retrospectively analyzed. Among them, 11 cases received preoperative abdominal CT and 4 cases received preoperative abdominal MR scanning. The clinical and imaging manifestations of ACC were observed. Results: Among 13 ACC children, 10 (10/13, 76.92%) were female, and most common clinical manifestations included obvious masculinization (9/13, 69.23%), Cushing syndrome (4/13, 30.77%), clitoral hypertrophy (3/13, 23.08%), pubic hair presbyopia (3/13, 23.08%), abdominal pain and abdominal mass (2/13, 15.38%). Ten children (10/13, 76.92%) had elevated serum androgen. CT showed largeadrenal masses with maximum diameter>6 cm in 7 cases (7/13, 53.85%), the lesions were lobulated in 8 (8/13, 61.54%) cases. Among 13 lesions, 5 (5/11, 45.45%) had uneven density with calcification foci. All lesions unevenly and obviously enhanced after enhancement (11/11, 100%), and "network-like" changes were observed in 8 cases (8/11, 72.23%). Tumor involvement of surrounding tissue and renal vein or inferior vena cava tumor thrombi were noticed in 2 cases (2/11, 18.18%). MR T2WI showed slightly high signal lesions in 3 cases and medium signal lesion in 1 case, all uneven enhanced after enhancement. Conclusion: Imaging manifestations of children ACC had certain characteristics, combining with clinical manifestations were helpful to diagnosis of this disease.

Protein Expression of Cyclin B1, Transferrin Receptor, and Fibronectin Is Correlated with the Prognosis of Adrenal Cortical Carcinoma

BACKGROUND: Adrenal cortical carcinoma (ACC) is a rare cancer with a variable prognosis. Several prognostic factors of ACC have been previously reported, but a proteomic analysis has not yet been performed. This study aimed to investigate prognostic biomarkers for ACC using a proteomic approach.METHODS: We used reverse-phase protein array data from The Cancer Proteome Atlas, and identified differentially expressed proteins in metastatic ACCs. Multivariate Cox regression analysis adjusted by age and staging was used for survival analysis, and the C-index and category-free net reclassification improvement (cfNRI) were utilized to evaluate additive prognostic value.RESULTS: In 46 patients with ACC, cyclin B1, transferrin receptor (TfR1), and fibronectin were significantly overexpressed in patients with distant metastasis. In multivariate models, high expression of cyclin B1 and TfR1 was significantly associated with mortality (hazard ratio [HR], 6.13; 95% confidence interval [CI], 1.02 to 36.7; and HR, 6.59; 95% CI, 1.14 to 38.2; respectively), whereas high fibronectin expression was not (HR, 3.92; 95% CI, 0.75 to 20.4). Combinations of high cyclin B1/high TfR1, high cyclin B1/high fibronectin, and high TfR1/high fibronectin were strongly associated with mortality ([HR, 13.72; 95% CI, 1.89 to 99.66], [HR, 9.22; 95% CI, 1.34 to 63.55], and [HR, 18.59; 95% CI, 2.54 to 135.88], respectively). In reclassification analyses, cyclin B1, TfR1, fibronectin, and combinations thereof improved the prognostic performance (C-index, 0.78 to 0.82–0.86; cfNRI, all P values <0.05).CONCLUSION: In ACC patients, the overexpression of cyclin B1, TfR1, and fibronectin and combinations thereof were associated with poor prognosis.

Right atrium tumor extension through the inferior vena cava. considerations about nine cases operated under cardiopulmonary bypass

Abstract Introduction: Adrenocortical and renal cell carcinomas rarely invade the right atrium (RA). These neoplasms need surgical treatment, are very aggressive and have poor prognostic and surgical outcomes. Case series: We present a retrospective cohort of nine cases of RA invasion through the inferior vena cava (four adrenocortical carcinomas and five renal cell carcinomas). Over 13 years (2002-2014), nine patients were operated in collaboration with the team of urologists. Surgery was possible in all patients with different degrees of technical difficulty. All patients were operated considering the imaging examinations with the aid of CPB. In all reported cases (renal or suprarenal), the decision to use CPB with deep hypothermic circulatory arrest (DHCA) on surgical strategy was decided by the team of urological and cardiac surgeons. Conclusion: Data retrospectively collected from patients of public hospitals reaffirm: 1) Low incidence with small published series; 2) The selected cases did not represent the whole historical casuistry of the hospital, since they were selected after the adoption of electronic documentation; 3) Demographic data and references reported in the literature were presented as tables to avoid wordiness; 4) The series highlights the propensity to invade the venous system; 5) Possible surgical treatment with the aid of CPB in collaboration with the urology team; 6) CPB with DHCA is a safe and reliable option; 7) Poor prognosis with disappointing late results, even considering the adverse effects of CPB on cancer prognosis are expected but not confirmed.

Late recurrence of adrenocortical carcinoma and metastatic disease. Case report / Recurrencia tardía de carcinoma adrenocortical con compromiso metastásico. Reporte de un caso

Abstract Introduction: Adrenocortical carcinoma (ACC) is a malignancy with an annual incidence of 0.72 cases per million people. It is a rare tumor that is associated with high mortality in late stages, as well as with a 5-year survival of 13% in stage IV patients, and 61% in stage II lesions. Nevertheless, tumor recurrence occurs in up to 54% at 23 months with predominance of locoregional involvement, being striking the late presentation of tumor recurrence with extensive involvement. Case presentation: This is the case of a 52-year-old male patient with a history of resection of an ACC of 6cm five years earlier, who was admitted for decompensated heart failure. A chest x-ray was taken and metastasis was suspected. After conducting biochemical studies and a CT scan of the abdomen, ACC with metastases to the liver and lung was diagnosed. The patient decided not to receive palliative chemotherapy. Conclusion: This unfortunate outcome is related to the lack of follow-up after the initial procedure. Clinical, hormonal, and imaging evaluation is recommended every 3 months for 2 years, and then at least every 6 months.

Resumen Introducción. El carcinoma adrenocortical (CAC) es una neoplasia que reporta incidencia anual de 0.72 casos por cada millón de personas. Se trata de un tumor infrecuente que se asocia con una mortalidad elevada en estadios avanzados y una supervivencia a 5 años del 13% de pacientes en estadio IV y del 61% para lesiones en estadio II; sin embargo, la presencia de recurrencia tumoral es hasta de 54% a los 23 meses con predominio de compromiso locoregional, siendo llamativa la presentación tardía de la recurrencia tumoral con compromiso extenso. Presentación del caso. Paciente masculino de 52 años con antecedente de resección de un CAC de 6cm de tamaño 5 años atrás, quien ingresa por falla cardíaca descompensada, encontrando en la radiografía de tórax una imagen sugestiva de metástasis. Tras estudios bioquímicos y tomografía de abdomen se diagnostica CAC con compromiso metastásico a hígado y pulmón. El paciente opta por no recibir manejo quimioterapéutico paliativo. Conclusión. Este desenlace desafortunado tiene relación con la ausencia de seguimiento tras el procedimiento inicial. Se recomienda evaluación clínica, hormonal e imagenológica cada 3 meses por 2 años y luego al menos cada 6 meses.

Carcinoma adrenal em crianças: estudo longitudinal em minas gerais, brasil / Adrenal carcinoma in children: longitudinal study in minas gerais, brazil

RESUMO Objetivo: Analisar as características clínicas, laboratoriais e histopatológicas e o percurso até o estabelecimento do diagnóstico e do tratamento de pacientes com carcinoma de suprarrenal (CSR). Métodos: Estudo retrospectivo com 13 pacientes tratados no serviço de oncologia pediátrica do Hospital das Clínicas da Universidade Federal de Minas Gerais (HC-UFMG) entre 2004 e 2015. Resultados: A idade ao diagnóstico variou de 1,0 a 14,8 anos (mediana: 2,0 anos). As manifestações de hipercortisolismo foram identificadas em todos os casos, e as de virilização, em todas as meninas. Todos os pacientes preencheram os critérios de Weiss para diagnóstico histopatológico de CSR. A imuno-histoquímica foi realizada em 61,5% dos casos. A maioria dos pacientes apresentou doença em estádio I (76,9%). Todos foram submetidos à ressecção tumoral total. Dois pacientes (estádios III e IV) receberam quimioterapia associada ao mitotano. O único óbito observado foi do paciente com doença em estádio IV. A probabilidade de sobrevida global para todo o grupo aos 5,0 anos foi de 92,3±7,4%. A mediana de tempo entre o início dos sintomas e o diagnóstico foi de 9,5 meses, e de 6,0 meses entre a primeira consulta e o início do tratamento. Conclusões: A baixa idade ao diagnóstico, o predomínio de casos com doença localizada e a ressecção tumoral completa - com apenas um caso de ruptura de cápsula tumoral - são possivelmente a explicação para a evolução favorável da população estudada. O longo percurso entre o início dos sintomas e o diagnóstico sugere a importância da capacitação dos pediatras para o reconhecimento precoce dos sinais e dos sintomas do CSR.

ABSTRACT Objective: To analyze clinical, laboratory and histopathological features and the path to diagnosis establishment and treatment of patients with adrenal carcinoma (AC). Methods: Retrospective study with 13 patients assisted at the pediatric oncology service of Hospital das Clínicas, Universidade Federal de Minas Gerais, Brazil, between 2004 and 2015. Results: Age at diagnosis ranged from 1.0 to 14.8 years (median: 2.0 years). Manifestations of hypercortisolism were identified in all cases and virilization in all girls. All patients met the Weiss criteria to AC histopathological diagnosis. Immunohistochemistry was performed in 61.5% of the cases. Most patients had stage I disease (76.9%). All subjects were submitted to total tumor resection. Two patients (stages III and IV disease) received chemotherapy associated to mitotane. The only death case was that of a patient with stage IV disease. The probability of overall survival for the entire group up to 5.0 years was 92.3±7.4%. The median time between the onset of symptoms and diagnosis was 9.5 months, and 6.0 months between first visit and start of treatment. Conclusions: Low age at diagnosis, predominance of cases with localized disease and complete tumor resection - with only one case of tumor capsule rupture - can possibly explain the favorable evolution of the studied population. The long period between onset of symptoms and diagnosis highlights the importance of training pediatricians for early recognition of AC signs and symptoms.

Carcinoma adrenocortical oncocítico virilizante / Adrenal oncocytic virilizing carcinoma

Las neoplasias oncocíticas se encuentran raramente en la glándula suprarrenal. Suelen ser benignos y no funcionales. Existen informes extremadamente limitados de neoplasias oncocíticas suprarrenales. Alrededor del 20% de las neoplasias oncocíticas adrenocorticales muestran componentes malignos y el 10-20% produce hormonas que pueden causar desbalances hormonales. Se presenta un carcinoma adrenocortical oncocítico virilizante en mujer de 35 años de edad quien acudió a consulta por presentar hipomenorrea secundaria de seis meses de duración acompañada de hirsutismo y agravamiento del acné que afectaba principalmente la cara. El examen de laboratorio revela niveles elevados de testosterona libre. La tomografía computada mostró tumor multinodular en la glándula suprarrenal derecha con necrosis central y sin evidencia de linfadenopatía o invasión de estructuras que la rodeaban. Se programó la adrenalectomía derecha lográndose resección completa del tumor. Después de la cirugía, se normalizaron los ciclos menstruales, el hirsutismo, el acné y el resto de las pruebas. El examen histopatológico del tumor fue compatible con carcinoma adrenocortical oncocítico(AU)

Oncocytic neoplasms are found more rarely in the adrenal gland. They are usually benign and nonfunctional. There are limited reports of adrenal oncocytic neoplasms. About 20% of adrenocortical oncocytic neoplasms show malignant components and 10-20% produce hormones that can cause hormonal imbalances. We present a virilizing oncocytic adrenocortical carcinoma in a 35-year-old woman who consulted for hypomenorrhea accompanied by hirsutism and face acne worsening. Laboratory test revealed high levels of free testosterone. Computed tomography showed multinodular tumor of the right adrenal gland with central necrosis and without evidence of lymphadenopathy or invasion of surrounding structures. A right adrenalectomy was performed. After surgery, menstrual cycle, hirsutism and acne, as well as hormonal tests were normal. Histopathological examination of tumor showed an oncocytic adrenocortical carcinoma(AU)

Diagnosis and prognosis of adrenocortical carcinoma in children / 中国肿瘤临床

Objective: To summarize the diagnosis and prognosis of adrenocortical carcinoma in children. Methods: Medical records of 10 pediatric patients with adrenocortical cancer treated in Children's Hospital of Nanjing Medical University from September 2010 to March 2018 were retrospectively reviewed, and their clinical manifestation, laboratory, auxiliary, and pathological examination results, and prognosis were analyzed. Results: The average age of all patients (5 male and 5 female pediatric patients) was (53.3+48.4) months. Clinical mani-festations included abdominal mass, hypertension, cortisol level, and peripheral precocious puberty. Laboratory tests showed that lactate dehydrogenase, neuroenolase, and cortisol levels were high in some patients, and sex hormones were abnormal. Auxiliary examination using the abdominal computed tomography enhancement showed irregular an adrenal gland, uneven density, necrosis, mass calcification, and some infiltration into the surrounding tissue. Pathological examination suggests tumor cell pleomorphism, more frequent pathological division, high mitotic index, abundant interstitial sinusoid, necrosis, tumor infiltration, vascular invasion, and Weiss score of≥3 points. Lactate acid dehydrogenase and cortisol levels; Weiss score; and tumor size, staging, and resection rate were not statistically different among prognostic factors. Conclusions: For pediatric patients with adrenal masses, the survival rate should be improved by combining the clinical manifestation, laboratory examination, and auxiliary examination for the early diagnosis of adrenocortical carcinoma and to select the appropriate treatment. Combined with pathological results, adrenocortical carcinoma can be well differentiated from other adrenal masses.

Advances in the diagnosis and treatment of adrenocortical carcinoma / 国际外科学杂志

Adrenocortical carcinoma is a malignant endocrine tumor.There is no unified standard for diagnosis and treatment because of the low incidence.There are two peaks in the age of onset,which are 0 to 10 years and 40 to 50 years,and the incidence of children and women is higher.The percentage of 60 to 70 ACC patients show clinical symptoms due to the excess hormone,but there are still many patients with poor clinical symptoms.The common endocrine symptoms include polycythemia,masculinity or male breast development.The prognosis of ACC is poor,and the classification and staging of the tumor and hypercortisol are associated with the prognosis.Surgical resection is the first choice,but the recurrence rate of the tumor is high and the overall survival rate is low after operation.In this paper,the clinical characteristics,diagnosis,differential diagnosis,prognosis and treatment of ACC are summarized by reviewing the past researches.

Estrogen-secreting adrenocortical carcinoma / 영남의대학술지

Adrenocortical carcinoma is a rare type of endocrine malignancy with an annual incidence of approximately 1–2 cases per million. The majority of these tumors secrete cortisol, and a few secrete aldosterone or androgen. Estrogen-secreting adrenocortical carcinomas are extremely rare, irrespective of the secretion status of other adrenocortical hormones. Here, we report the case of a 53-year-old man with a cortisol and estrogen-secreting adrenocortical carcinoma. The patient presented with gynecomastia and abdominal discomfort. Radiological assessment revealed a tumor measuring 21×15.3×12 cm localized to the retroperitoneum. A hormonal evaluation revealed increased levels of estradiol, dehydroepiandrosterone sulfate, and cortisol. The patient underwent a right adrenalectomy, and the pathological examination revealed an adrenocortical carcinoma with a Weiss' score of 6. After surgery, he was treated with adjuvant radiotherapy. Twenty-one months after treatment, the patient remains alive with no evidence of recurrence.

Primary malignant tumors of the adrenal glands

Malignancy must be considered in the management of adrenal lesions, including those incidentally identified on imaging studies. Adrenocortical carcinomas (ACCs) are rare tumors with an estimated annual incidence of 0.7-2 cases per year and a worldwide prevalence of 4-12 cases per million/year. However, a much higher incidence of these tumors (>15 times) has been demonstrated in south and southeastern Brazil. Most ACCs cause hypersecretion of steroids including glucocorticoids and androgens. ACC patients have a very poor prognosis with a 5-year overall survival (OS) below 30% in most series. Pheochromocytoma or paraganglioma (PPGL) is a metabolically active tumor originating from the chromaffin cells of the adrenal medulla. The incidence of PPGL is 0.2 to 0.9 cases per 100,000 individuals per year. Pheochromocytomas are present in approximately 4-7% of patients with adrenal incidentalomas. Classically, PPGL manifests as paroxysmal attacks of the following 4 symptoms: headaches, diaphoresis, palpitations, and severe hypertensive episodes. The diagnosis of malignant PPGL relies on the presence of local invasion or metastasis. In this review, we present the clinical and biochemical characteristics and pathogenesis of malignant primary lesions that affect the cortex and medulla of human adrenal glands.

Approach to the patient with aldosterone-producing adrenocortical carcinoma / 中华内分泌代谢杂志

Aldosterone-producing adrenocortical carcinoma (ACC) is a rare endocrine malignancy. Only a few cases are reported in China. This systematic review investigated the diagnosis and treatment strategy of aldosterone-producing ACC through a recent case of the disease. A case of a 49-year-old female who diagnosed with aldosterone-producing ACC by hormonal assays, medical imaging and pathology. Her condition has been alleviated after surgery. Aldosterone-producing ACC is a rare malignancy with limited treatment options and surgery is the primary treatment strategy.
