Tumor de ovario de los cordones sexuales con túbulos anulares: reporte de caso y revisión de la literatura / Ovarian sex cord tumor with annular tubules: case report and review of the literature

RESUMEN Objetivos: Reportar un caso de Tumor de Ovario de los Cordones Sexuales con Túbulos Anulares (TCSTA), hacer una revisión de la literatura acerca del diagnóstico, tratamiento y pronóstico de esta condición. Materiales y métodos: Se informa el caso de una mujer que consultó al Instituto Nacional de Cancerología, Bogotá (Colombia), con diagnóstico final de TCSTA avanzado, quien recibió tratamiento quirúrgico y quimioterapia con evolución satisfactoria a los 6 meses. Se realizó una búsqueda de la literatura en las bases de datos Medline vía PubMed, LILACS y Scielo, que incluía reportes y series de caso de mujeres con diagnóstico de TCSTA, publicados desde 1990, sin incluir rango de edad. Se extrajo información sobre el diagnóstico, tratamiento y pronóstico reportado. Se realizó resumen narrativo de los hallazgos. Resultados: Se incluyeron 14 publicaciones que incluían 26 pacientes. La edad media al diagnóstico fue de 22,5 años. Los síntomas principales fueron alteraciones de la menstruación y dolor pélvico. La tomografía computarizada fue la tecnología de imágenes más frecuentemente utilizada. El tratamiento fue quirúrgico, siempre usado, acompañado de quimioterapia (29 %); 2 casos recibieron radioterapia. Hubo recaída en el 20 % de los casos. La mortalidad fue del 12,5 %, toda en el primer año. Conclusiones: La información sobre la utilidad diagnóstica de las imágenes, marcadores tumorales y estudios de histoquímica es escasa, como también los datos sobre el pronóstico de la entidad. El tratamiento quirúrgico es el de elección, teniendo en cuenta el deseo de fertilidad de la paciente y el estadio tumoral. Se requieren más estudios que documenten de manera más detallada el manejo de esta condición.

ABSTRACT Objectives: To report a case of ovarian sex cord tumor with annular tubules (SCTAT) and conduct a literature review on diagnosis, treatment and prognosis of this condition. Material and methods: Case report of a woman with a final diagnosis of advanced SCTAT seen at the National Cancer Institute in Bogota (Colombia) who received surgical treatment and chemotherapy with a satisfactory course after 6 months. A literature search was conducted in the Medline via PubMed, LILACS and Scielo databases, including case reports and series of women diagnosed with SCTAT published since 1990, not using age ranges. Information about diagnosis, treatment and reported prognosis was retrieved. A narrative summary of the findings was prepared. Results: Fourteen publications with 26 patients were included. Mean age at diagnosis was 22.5 years. The main symptoms were menstruation abnormalities and pelvic pain. Computed tomography (CT) was the imaging technology most frequently used. Surgical treatment was used in all cases, together with chemotherapy in 29 %; 2 patients received radiotherapy. Recurrence occurred in 20 % of cases. Mortality was 12.5 %, with all deaths occurring within the first year. Conclusions: There is a paucity of information about the diagnostic utility of imaging, tumor markers and histochemical studies, as well as prognosis of this disease condition. Surgery is the treatment of choice, taking into consideration the patient's wishes regarding fertility, as well as the stage of the tumor. Further studies are needed to provide more detailed information about this condition.

Introducción: El síndrome de Peutz-Jeghers se caracteriza por hiperpigmentación mucocutánea y hamartomas gastrointestinales que pueden aparecer desde el estómago hasta el ano. Tiene un patrón de herencia autosómico dominante y expresividad variable. El diagnóstico se basa en los hallazgos clínicos y la apariencia histológica de los pólipos. No ha sido reportado hasta ahora asociación de esta entidad a telangiectasias y prolapso de la válvula mitral. Objetivo: Describir los hallazgos que permitieron establecer el diagnóstico de Síndrome de Peutz-Jeghers en un paciente y brindar asesoramiento genético. Presentación del caso: Paciente masculino de 36 años de edad con antecedentes de prolapso de la válvula mitral que acude a consulta de genética clínica con su esposa para solicitar asesoramiento genético, debido a que tienen una hija con diagnóstico de Síndrome de Peutz-Jeghers y desean conocer el riesgo de tener otro hijo afectado. Al examen físico se observa mácula hiperpigmentada en labio inferior y varias de estas en encías. Con tales hallazgos y el antecedente de tener la hija Síndrome de Peutz-Jeghers se emite el mismo diagnóstico en el padre. Como dato de interés se constatan en este individuo múltiples telangiectasias en tórax, cuello y espalda. Los estudios realizados en busca de la causa de estas fueron negativos. Conclusiones: Los antecedentes y los hallazgos encontrados en el paciente permitieron realizar el diagnóstico de Peutz-Jeghers y brindar asesoramiento genético. Se presenta el primer reporte de esta enfermedad asociada a telangiectasias y prolapso de la válvula mitral en la literatura científica(AU)

Introduction: Peutz-Jeghers syndrome is characterized by mucocutaneous hyperpigmentation and gastrointestinal hamartomas that can appear from the stomach to the anus. It has an autosomal dominant inheritance pattern and variable expressiveness. The diagnosis is based on clinical findings and histological appearance of the polyps. No association between this entity and telangiectasias and mitral valve prolapse has been reported so far. Objective: To describe the findings that made it possible to establish the diagnosis of Peutz-Jeghers syndrome in a patient and to provide genetic counseling. Case presentation: Thirty-six-year-old male patient with a history of mitral valve prolapse who attends a clinical genetics consultation with his wife to request genetic counseling due to the fact that their daughter was diagnosed with Peutz-Jeghers Syndrome and they want to know about the risk of having another affected child. On physical examination, a hyperpigmented macule on the lower lip and several of these on the gums were observed. With such findings and the antecedent of having a daughter with Peutz-Jeghers syndrome, the same diagnosis is made in the father. As data of interest, multiple telangiectasias on the thorax, neck and back were found in this individual. The studies carried out to identify the same cause were negative. Conclusions: The history and findings in this patient allowed us to make the diagnosis of Peutz-Jeghers syndrome as well as to provide genetic counselling. The first report of this disease associated with telangiectasias and mitral valve prolapse is presented in the scientific literature(AU)

Peutz-Jeghers syndrome: an unusual autopsy finding in pregnancy

Peutz-Jeghers syndrome (PJS) is a rare autosomal dominant polyposis entity that often remains undiagnosed. The major problems associated with PJS are acute complications due to (i) polyp-related intestinal obstruction, (ii) intussusception, and (iii) the risk of cancer in the long-term. We report the case of a 32-year-old female who presented at the emergency room with signs of acute abdomen and died during the clinical workup. She had a one-month history of nausea, vomiting, and diarrhea and was pregnant at about 30 weeks. There was no contributing past history except for undergoing small bowel resection in infancy. The postmortem examination revealed multiple arborizing polyps throughout the gastrointestinal tract, chiefly in the small bowel. Intestinal obstruction was found at the proximal jejunum with necrosis, perforation, and peritonitis. Histologically, the polyps were composed of tree branch-like bundles of smooth muscle covered by normal-appearing glandular epithelium, confirming the diagnosis of hamartomatous polyps. No malignant or premalignant lesions were detected in the gastrointestinal tract or other organs. This case was an opportunity to analyze the natural history and the pathological features of the Peutz-Jeghers syndrome in an adult and to investigate the presence of neoplastic lesions associated with this condition.

Manejo da síndrome de Peutz-Jeghers no contexto de recursos limitados / Peutz-jeghers syndrome in resource-limited scenario

ABSTRACT BACKGROUND: Peutz-Jeghers Syndrome (PJS) is a rare, autosomal dominant disease, caused by deletions in the chromosome 19p33.3/ gene LKB1/STK11. These mutations inactivate a serine/threonine kinase and predispose to carcinogenesis. In PJS, tumors of the gastrointestinal, testicles, pulmonary, breast, pancreas, uterus and ovaries can be found. OBJECTIVE: To evaluate demographics, clinical presentation and complication/outcomes of pediatric patients presenting with Peutz-Jeghers syndrome (PJS), as well as to present and discuss management in the context of limited resources. METHODS: We conducted a retrospective chart review of a cohort of six patients, who were diagnosed and/or followed at the Clinics Hospital, University of Campinas - Sao Paulo/Brazil, between 2000 and 2018. Data analyzed included gender, age of presentation, age of diagnosis, family history, PJS complications. RESULTS: Median age of diagnosis of 6.7 years, with a mean time of follow-up of 8.1 years. Mucocutaneous pigmentation was universally present. Half of the patients had a known family history at the time of diagnosis. On follow up, intestinal intussusception was documented in four out of six patients, in most (three), in different locations and in multiple occasions. The active investigation of siblings and parents of the index case led to the diagnosis of three first-degree relatives in the present case series. CONCLUSION: In this first pediatric PJS Brazilian case series, we report a wide spectrum of PJS manifestations and complications. In a resource limited scenario, despite limitations for the surveillance of complications, the relative frequency of complications was not higher than historically reported.

RESUMO CONTEXTO: A síndrome de Peutz-Jeghers (SPJ) é uma doença autossômica dominante rara, causada por deleções no cromossomo 19p33.3/gene LKB1/STK11. Essas mutações inativam uma serina/treonina quinase e predispõem à carcinogênese. Na SPJ, podem ser encontrados tumores do trato gastrointestinal, testicular, pulmonar, de mama, de pâncreas, de útero e de ovários. OBJETIVO: Avaliar dados demográficos, apresentação clínica e complicações de pacientes pediátricos que se apresentam com SPJ, além de apresentar e discutir o manejo no contexto de recursos limitados. MÉTODOS: Realizamos uma revisão retrospectiva de prontuários de uma coorte de seis pacientes, diagnosticados e/ou acompanhados no Hospital das Clínicas da Universidade de Campinas - São Paulo, Brasil, entre 2000 e 2018. Os dados analisados incluíram sexo, idade de apresentação, idade do diagnóstico, história familiar, complicações da SPJ. RESULTADOS: Idade média de diagnóstico de 6,7 anos, com tempo médio de seguimento de 8,1 anos. A pigmentação mucocutânea estava universalmente presente. Metade dos pacientes tinha um histórico familiar conhecido no momento do diagnóstico. Intussuscepção intestinal foi observada em quatro dos seis pacientes durante o período de acompanhamento, sendo que em três ocorreram vários episódios em diferentes múltiplas localizações. A investigação ativa de irmãos e pais do caso-índice levou ao diagnóstico de três parentes de primeiro grau na presente série de casos. CONCLUSÃO: Nesta primeira série de casos brasileiros de SPJ pediátrica, relatamos um amplo espectro de manifestações e complicações da SPJ. Em um contexto de recursos limitados, apesar das limitações para a vigilância de complicações, a frequência relativa de complicações não foi maior do que o relatado historicamente.

A rare case of gastric-type mucinous adenocarcinoma in a woman with Peutz-Jeghers syndrome

Adenocarcinoma of the cervix is less common than squamous cell carcinoma. Minimal deviation adenocarcinoma (adenoma malignum) is considered an extremely well-differentiated variant of GAS. An association exists between GAS and Peutz-Jeghers syndrome, which is a rare autosomal dominant disorder characterized by mucocutaneous pigmentation and multiple hamartomatous polyps in the gastrointestinal tracts. The incidence of GAS in patients with Peutz-Jeghers syndrome is estimated to be 11–17%. We present a rare case of adenoma malignum, diagnosed using colposcopic biopsy in a woman with Peutz-Jeghers syndrome, which was histopathologically confirmed to be GAS after surgery.

Analysis of STK11 gene variants among 64 patients with Peutz-Jeghers syndrome / 中华医学遗传学杂志

OBJECTIVE@#To screen for pathogenic variants in the coding regions of STK11 gene among Chinese patients with Peutz-Jeghers syndrome (PJS).@*METHODS@#Peripheral blood samples were collected from 64 patients. The coding regions of the STK11 gene were detected by PCR and Sanger sequencing.@*RESULTS@#Fourty-eight patients were found to harbor STK11 gene variants, which included 39 types of variants consisting of missense, nonsense, insertional, deletional and splice site variants. Among 64 PJS patients, the detection rate of point variants was 75.00% (48/64), of which missense variants accounted for 29.17% (14/48), nonsense variants accounted for 29.17%(14/48), insertion variants accounted for 2.08% (1/48), deletional variants accounted for 10.42% (5/48), and splice site variants accounted for 29.17% (14/48). The detection rates of sporadic cases and those with a family history were 71.8% (28/39) and 80.0% (20/25), respectively. Two variants (c.250A>T, c.580G>A) occurred in 3 PJS probands. Thirteen variants were unreported previously and were considered to be pathogenic.@*CONCLUSION@#The detection rate of variants among Chinese PJS patients is similar to that of other countries. A number of novel common variant sites were discovered, which enriched the spectrum of PJS-related variants.

Síndrome de Peutz-Jeghers como causa de invaginación intestinal en niño / Peutz-Jeghers syndrome as a cause of intestinal intussusception in children

La invaginación intestinal se presenta con mayor frecuencia en el lactante menor de 2 años, con un pico entre los 5 y 9 meses de edad. En la gran mayoría de los casos es idiopática o de causa desconocida, probablemente secundaria a una infección viral que provoca un crecimiento del tejido linfático intestinal. Sólo en un 2-8% de los pacientes se demuestra una alteración anatómica como causa de la intususcepción (divertículo de Meckel, pólipo). Es la llamada invaginación intestinal secundaria, que suele presentarse en los menores de 3 meses o mayores de 3 años. El síndrome de Peutz-Jeguers (SPJ) es una condición rara y su frecuencia es probablemente inferior a 1/50,000. Se caracteriza por la presencia de pólipos hamartomatosos potencialmente malignos en el tracto digestivo asociada a pigmentaciones mucocutáneas características. Los datos actuales sugieren la existencia de al menos 2 genes implicados: STK11 (19p13.3), identi cado recientemente, es el responsable de la enfermedad en el 70% de las familias. Se describe el caso de dos adolescentes con cuadro de Intususcepción intestinal con diagnóstico de poliposis familiar de Peutz-Jeghers, requiriendo ambas procedimiento quirúrgico

Intestinal intussusception occurs more frequently in the infant younger than 2 years, with a peak between 5 and 9 months of age. In the vast majority of cases it is idiopathic or of unknown cause, probably secondary to a viral infection that causes a growth of the intestinal lymphatic tissue. Only in 2-8% of the patients an anatomical alteration as cause of the intussusception is demonstrated (Meckel's diverticulum, polyp). It is called secondary intestinal invagination, which usually occurs in children under 3 months or older than 3 years. Peutz-Jeguers syndrome (SPJ) is a rare condition and its frequency is probably less than 1 / 50,000. It is characterized by the presence of potentially malignant hamartomatous polyps throughout the digestive tract associated with characteristic mucocutaneous pigmentations. Current data suggest the existence of at least 2 genes involved: STK11 (19p13.3), recently identi ed, is responsible for the disease in 70% of families. We describe the case of two adolescents with intestinal intussusception with a diagnosis of familial polyposis of Peutz Jeghers, requiring both surgical procedures

Small Bowel Tumors and Polyposis: How to Approach and Manage? / 대한소화기학회지

Although small bowel the mainly occupies the most part of the gastrointestinal tract, small intestine tumors are rare, insidious in clinical presentation, and frequently represent a diagnostic and management challenge. Small bowel tumors are generally classified as epithelial, mesenchymal, lymphoproliferative, or metastatic. Familial adenomatous polyposis and Peutz-Jeghers syndrome are the most common inherited intestinal polyposis syndromes. Until the advent of capsule endoscopy (CE) and device-assisted enteroscopy (DAE) coupled with the advances in radiology, physicians had limited diagnostic examination for small bowel examination. CE and new radiologic imaging techniques have made it easier to detect small bowel tumors. DAE allows more diagnosis and deeper reach in small intestine. CT enteroclysis/CT enterography (CTE) provides information about adjacent organs as well as pictures of the intestinal lumen side. Compared to CTE, Magnetic resonance enteroclysis/enterography provides the advantage of soft tissue contrast and multiplane imaging without radiation exposure. Treatment and prognosis are tailored to each histological subtype of tumors.

Minimal deviation adenocarcinoma (adenoma malignum) of the uterine cervix: clinicopathological analysis of 17 cases

OBJECTIVE: The aim of this study was to evaluate the clinicopathological features of minimal deviation adenocarcinoma (MDA) and to analyze its prognostic factors. METHODS: We retrospectively analyzed the medical records of 17 patients who were diagnosed with MDA at a single institution between January 2005 and December 2015. RESULTS: The median age of the patients was 47.7 years (33–75 years). MDA was diagnosed in 7 patients (41.2%) before performing definitive surgery. Stage IB disease was diagnosed in 12 patients (70.6%) and advanced stage disease (stage II: 3, stage III: 2) in 5. MDA was incidentally diagnosed following hysterectomy for benign conditions in 6 patients. Adjuvant therapy was administered to 13 patients (76.5%). During median follow-up over 33.6 months (7–99 months), 11 patients (64.7%) showed no evidence of disease, 6 (35.3%) showed persistent or recurrent disease and 5 died of the disease. Peutz-Jeghers syndrome was not suspected in any patient, and no mutation was detected in the 3 patients who underwent genetic testing. Univariate analysis showed that advanced stage disease (P=0.016) and lymphovascular space invasion (P=0.002) demonstrated a statistically significant association with poor overall survival (OS) rates. Advanced stage disease continued to show a significant association with poor OS rates (hazard ratio, 2.92; 95% confidence interval, 1.097–7.746; P=0.032) even after multivariate analysis. CONCLUSION: Early diagnosis is important to manage MDA. Clinicians should consider MDA among the differential diagnoses in patients with a suspicious clinical presentation even with negative cervical screening tests.

Diagnosis and treatment for 46 cases of Peutz-Jeghers syndrome / 中南大学学报(医学版)

To explore the clinical features, pathological features, gene test results, diagnosis, treatment and prognosis of Peutz-Jeghers syndrome(PJS).
 Methods: We retrospectively analyzed clinical data of 46 hospitalized cases of PJS during 2007 and 2017.
 Results: All 46 patients had mucocutaneous melanin pigmentation and multiple gastrointestinal polyposis. The pigmentation was first noticed often within 5 years old, and 14 cases had family history. The clinical manifestations mainly included black spots, abdominal pain, hematochezia, and anemia. Histological examinations showed that 20 patients were classified as hamartomatous polyps,18 as adenomatous polyps, 14 as inflammatory polyps, and 10 as zigzag polyps. Eleven patients sequenced a panel of 20 genes previously associated with colorectal cancer (CRC) by next-generation sequencing, and the results showed 5 patients with gene mutations, and 3 of them with intussusception and surgical histories were found to have pathogenic germline mutations in the STK11 gene. Endoscopic treatment was the main therapy, but endoscopy combined with laparoscopy or surgical treatment was performed when complications occurred or the polyp was too large. Malignant tumors were found in 3 patients during follow-up.
 Conclusion: PJS is a hereditary disease which is characterized by spots of the skin or mucosa and gastrointestinal multiple polyps. The main pathological features are hamartoma and adenoma. The risks for intussusception and surgical operation are found to be high in the patients with pathogenic germline mutations in the STK11 gene. Endoscopic treatment is the main therapy. PJS patients should be followed up regularly due to the increasing risk for cancer and being easily to relapse.

Síndrome de Peutz-Jeghers: novos dados e bases moleculares sobre uma doença rara / The Peutz-Jeghers syndrome: new data and molecular bases on a rare disease

A síndrome de Peutz-Jeghers é uma associação de polipose no trato gastrointestinal do tipo familiar e pigmentação melânica mucocutânea, particularmente nos lábios, mucosa bucal e polpa digital. Há poucas décadas, algumas centenas de casos haviam sido descritos na literatura, o que torna a doença não tão rara. O objetivo deste trabalho foi relatar casos clínicos em que os pacientes eram portadores da síndrome. Em um dos casos, tia e sobrinha evidenciaram a implicação genética da doença. Dados clínicos, bases moleculares e resultados histopatológicos, com a utilização de anticorpos (Ac) monoclonais, mostram a relevância do trabalho. Portadores crônicos da síndrome após décadas, ainda não diagnosticados, procuram o cirurgião-dentista para tratamentos diversos, dando-lhe oportunidade e responsabilidade na detecção da doença, devido ao risco de desenvolvimento de tumores malignos no trato gastrointestinal.

The Peutz-Jeghers syndrome is a familiar association of polyposis in the gastrointestinal tract and melanic mucocutaneous pigmentation, particularly in the lips, oral mucosa and fi ngertips. A few decades few hundred cases had been described in the literature wich makes the disease not so rare. The objective of this study is to report clinical cases where patients were carriers of the syndrome. In one of the cases the aunt and nice showed the genetic implication of the disease. Clinical data, molecular basis and histopathological results with monoclonal antibodies (Ac), show the relevance of this work. Chronic carriers of the syndrome after decades, still undiagnosed, seek the dentist for various treatments giving him the opportunity and responsibility to detect the disease due to the risk of development of malignant tumors in the gastrointestinal tract.

Familial Pancreatic Cancer and the Future of Directed Screening

Pancreatic cancer (PC) is the third most common cause of cancer-related death in the United States and the 12th most common worldwide. Mortality is high, largely due to late stage of presentation and suboptimal treatment regimens. Approximately 10% of PC cases have a familial basis. The major genetic defect has yet to be identified but may be inherited by an autosomal dominant pattern with reduced penetrance. Several known hereditary syndromes or genes are associated with an increased risk of developing PC and account for approximately 2% of PCs. These syndromes include the hereditary breast-ovarian cancer syndrome, Peutz-Jeghers syndrome, familial atypical multiple mole melanoma, Lynch syndrome, familial polyposis, ataxia-telangiectasia, and hereditary pancreatitis. Appropriate screening using methods such as biomarkers or imaging, with endoscopic ultrasound and magnetic resonance imaging, may assist in the early detection of neoplastic lesions in the high-risk population. If these lesions are detected and treated before the development of invasive carcinoma, PC disease morbidity and mortality may be improved. This review will focus on familial PC and other hereditary syndromes implicated in the increased risk of PC; it will also highlight current screening methods and the future of new screening modalities.
