Pseudotumour of the Testis-Awareness Prevents Mismanagement.

Inflammatory pseudotumour of the testis is a rare but important clinical entity to be recognised by the surgical trainee. We present a case of a 30-year-old gentleman who presented with a hard painless testicular mass. Ultrasound scrotum revealed a diffuse paratesticular swelling arising from the tunica vaginalis with a normal-appearing testis. Germ cell tumour markers were normal. Exploration through an inguinal approach confirmed it to be arising from the tunica vaginalis. Wide excision of the tumour along with a cuff of adherent tunica albuginea was done. Final histopathology revealed a diffuse fibrous pseudotumour of the tunica vaginalis confirming its benign nature.

The Histopathological Spectrum of Scrotal Lesions in a Tertiary Care Hospital: A Cross-Sectional Study.

BACKGROUND: The incidence and clinical presentation of testicular and paratesticular lesions are variable. A preoperative diagnosis is often difficult with only a clinical examination. The diagnosis of testicular lesions is mainly based on histological investigation, despite advances in imaging and tumor marker testing. This study aimed to document the histopathological spectrum of scrotal lesions, including testicular and paratesticular lesions. AIM: The study aimed to research the histopathological spectrum of scrotal lesions. SETTINGS AND DESIGN: This was a cross-sectional study conducted at NKP Salve Institute of Medical Sciences & Research Centre and Lata Mangeshkar Hospital, a tertiary care hospital in Nagpur, India. MATERIALS AND METHODS: Following the institutional ethics committee's approval, a two-year cross-sectional study was carried out in the tertiary care hospital. Seventy operated scrotal specimens sent for histopathological examination were included in the study. The clinical details and investigations of the patients, as well as the gross and histopathological findings of all the specimens, were studied carefully. STATISTICAL ANALYSIS: The clinical details and gross and histopathological findings were noted in a proforma, entered in a Microsoft Excel sheet (Microsoft Corp., Redmond, WA), and verified. The data were presented in a tabular form using tablets, pie charts, and bar diagrams. The collected data were analyzed and presented in percentages and frequencies. RESULTS: The present study evaluated the histopathological spectrum of scrotal lesions in 70 operated scrotal masses. The mean age of the participants in the study was 46.55 ± 18.69 years, with the youngest patient at four years and the oldest being 88 years of age. Sixty-six (80%) of the 70 cases were of non-neoplastic lesions, while 14 (20%) were of neoplastic lesions. Testicular atrophy (16 cases) was the most common non-neoplastic lesion. The most frequent neoplastic lesion in the present study was a seminoma (seven cases). CONCLUSION: This study strongly recommends routine histopathological examination of all scrotal specimens for the detection of various testicular and paratesticular lesions, as well as neoplasms. Histopathology not only provides a tissue diagnosis in scrotal disorders, but it also adds to understanding etiopathogenesis and can aid in the development of future treatment options.

Testicular mesothelioma disguised as hydrocele: a case report.

BACKGROUND: Testicular tumors have many different manifestations. The majority of these cases are presented as an incidental finding during hydrocelectomy. Malignant mesotheliomas are uncommon tumours that can arise from the coelomic epithelium of the pleura, peritoneum, pericardium, and tunica vaginalis. CASE PRESENTATION: We present a 51-year-old South Asian (Indian) male patient with a rare case of mesothelioma, presenting with right hydrocele, to whom a right hydrocelectomy was performed. Any history of trauma or asbestos exposure was not present. Histopathological and immunohistochemistry reports revealed a malignant mesothelioma of tunica vaginalis. There was no invasion of the tumour to the epididymis and spermatic cord. Imaging studies showed no signs of metastasis. 1 month later, a high inguinal orchidectomy was performed. The patient underwent adjuvant chemotherapy thereafter and is still on follow-up. CONCLUSION: Although hydrocele is common, detailed evaluation is mandatory to rule out certain rare tumours-testicular and paratesticular variants.

Epididymal Adenomatoid Tumour: A Case Report.

Adenomatoid tumours are rare benign neoplasm involving the para testicular region, mostly the tail of the epididymis. They are typically small, firm and asymptomatic masses in the scrotal region and often discovered incidentally during physical examination or imaging studies. It is very challenging to differentiate them clinically and radiologically from malignant intratesticular solid tumours, which may lead to unnecessary orchidectomies. This case report presents the clinical management of a 57-year-old male patient with adenomatoid tumour of the epididymis, highlighting the diagnostic workup, surgical approach and postoperative outcomes. In addition, a comprehensive literature review was conducted to discuss the morphological and immunohistochemical features to improve understanding of these rare lesions and assist in accurate diagnosis and appropriate management.

News in the fifth edition of World Health Organization classification of testicular tumors.

BACKGROUND: The fifth edition of World Health Organization classification of urinary and male genital tumours also brought news regarding testicular tumours. In contrast to the previous editions' radical alterations, the adjustments in the fifth edition are subtle and mostly impact the terminology, categorization of some of the rare tumours and diagnostic criteria. PURPOSE: Acquainting with current terms and tumor classification, which is necessary for good clinical practice.

The Diagnostic Power of the Platelet Mass Index for Testicular Tumours: A Simple Blood Test / El poder diagnóstico del índice de masa plaquetaria para los tumores testiculares: un simple análisis de sangre

Introduction: The relationship between inflammation and cancer has long been the focus of researchers' interest. There are many inflammatory markers studied for this purpose in the literature. In this context, we focused on the effects of platelet counts and platelet mass index (PMI) as inflammatory markers in the diagnosis of low-volume localized testicular cancer. Materials and methods: Thirty-eight patients with localized testicular cancer with a mean age of 30.84 ± 5.79 years and 38 patients with varicocele as a control group with a mean age of 32.8 ± 9.7 years were enrolled in the study. Number of platelets, mean platelet volume and value of PMI were calculated from peripheral blood samples obtained. Results: Number of platelets and PMI values were statistically significantly higher in patients with testicular cancer compared with the control group (p<.05). Conclusions: Both platelet counts and PMI values can be used as a simple test in the diagnosis of testicular cancer besides the well-known accurate serum tumor markers as AFP (alpha fetoprotein), hCG (human chorionic gonadotropin) and LDH (lactate dehydrogenase).

Introducción: La relación entre la inflamación y el cáncer ha sido durante mucho tiempo el foco de interés de los investigadores. Hay muchos marcadores inflamatorios estudiados con este propósito en la literatura. En este contexto, nos centramos en los efectos del recuento de plaquetas y el índice de masa plaquetaria (PMI) como marcadores inflamatorios en el diagnóstico de cáncer testicular localizado de bajo volumen. Materiales y métodos: Se incluyeron en el estudio 38 pacientes con cáncer testicular localizado con una edad media de 30,84 ± 5,79 años y 38 pacientes con varicocele como grupo control con una edad media de 32,8 ± 9,7 años. El número de plaquetas, el volumen medio de plaquetas y el valor de PMI se calcularon a partir de muestras de sangre periférica obtenidas. Resultados: El número de plaquetas y los valores de PMI fueron estadísticamente significativamente más altos en los pacientes con cáncer testicular en comparación con el grupo de control (p <.05). Conclusiones: Tanto el recuento de plaquetas como los valores de PMI se pueden utilizar como una prueba simple en el diagnóstico de cáncer testicular, además de los marcadores tumorales séricos precisos bien conocidos como AFP (alfa fetoproteína), hCG (gonadotropina coriónica humana) y LDH (lactato deshidrogenasa).

Environmental Pollution as a Risk Factor in Testicular Tumour Development: Focus on the Interaction between Bisphenol A and the Associated Immune Response.

Bisphenol A (BPA) is an endocrine disruptor to which animals and humans are highly exposed. Many reports have established a relationship between BPA exposure and breast cancer incidence, especially during critical periods of development. However, its effects on the immune response in testicular tumour growth have not yet been described. Thus, we wanted to analyse the effect of perinatal BPA exposure in pregnant female mice and the immune response modulation and tumour growth in an intratesticular cancer model in offspring male mice. Pregnant female mice were exposed to a dose of 250 mg/kg/day/body weight of BPA in their drinking water. In adulthood, male offspring underwent intrascrotal inoculation with 4T1 cancer cells. On day 21 after inoculation, mice were euthanised, and serum was obtained to measure BPA levels using HPLC coupled to mass spectrometry. The percentages of immune cell populations in peripheral lymph nodes (PLN), the spleen and tumours were evaluated by flow cytometry. In addition, the tumour expression of IL-10, TNF-α and TGF-ß was analysed by RT-PCR. Of note, we found detectable circulating levels of BPA in the offspring of mothers exposed to it while pregnant. Remarkably, BPA treatment promoted tumour growth by about 75% compared to mice coming from female mice that did not receive the compound. Perinatal exposure to BPA modulated the percentages of different immune cells in the spleen and PLN. In addition, the expression of inflammatory-related cytokines (IL-10 and TNF-α) in the tumours was significantly enhanced compared to control and vehicle groups. In conclusion, the perinatal BPA administration in pregnant female mice modulated different cellular and molecular immune components that resulted in outstanding testicular tumour size in male offspring.

May High Levels of Systemic Immune-Inflammation Index and Hematologic Inflammation Markers Suggest a Further Stage in Testicular Tumours?

INTRODUCTION: Due to variety of treatment alternatives for testicular tumours, parameters other than existing staging criteria are also needed. Most studies have revealed the correlation between cancer and inflammation. In this study, we aimed to investigate the value of preoperative inflammatory markers between early-stage testicular tumours and patients with advanced-stage, their relationship with tumour pathology and their importance in predicting stage. To calculate the differences between inflammatory markers, stage 1 tumours localized to the testis and advanced-stage tumours spread beyond the testis were classified into 2 groups according to tumour pathology. MATERIALS AND METHODS: The data of 112 patients undergoing inguinal orchiectomy in between 2008 and 2018 were recorded retrospectively. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and systemic immune-inflammation index (SII) were calculated by using the numbers of blood cell counts based systemic markers of inflammation. The differences between markers of inflammation were calculated by dividing tumours into 2 groups including early-stage and advanced- stage testicle tumours. RESULTS: According to the results of preoperative inflammatory markers in predicting the stage; in the seminoma group, the difference between the median NLR (2.37 vs. 4.39, p = 0.012), LMR (3.80 vs. 2.40, p = 0.018) and SII (612 vs. 1,127, p = 0.009) of stage 1 and advanced stage were statistically significant, while in the non-seminoma group, only the difference between median PLR (99 vs. 154, p = 0.002) of stage 1 and advanced stage was statistically significant. Sensitivity and specificity of predicting advanced stage according to cut-off values of markers were 69 and 75% in NLR (3.21), 83 and 75% in LMR, and 59 and 75% in SII in the seminoma group; on the other hand, in the non-seminoma group, the sensitivity, and specificity of predicting the advanced stage of PLR cut-off (104) were 71 and 88% respectively. CONCLUSIONS: The clinical use of inflammatory biomarkers in testicular tumours may represent an important step in understanding germ cell tumours biology and in supporting staging criteria and prognostic criteria.

Dynamic contrast-enhanced and diffusion-weighted MR imaging in the characterisation of small, non-palpable solid testicular tumours.

OBJECTIVES: To explore the role of dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI), using semiquantitative and quantitative parameters, and diffusion-weighted (DW) MRI in differentiating benign from malignant small, non-palpable solid testicular tumours. METHODS: We calculated the following DCE-MRI parameters of 47 small, non-palpable solid testicular tumours: peak enhancement (PE), time to peak (TTP), percentage of peak enhancement (Epeak), wash-in-rate (WIR), signal enhancement ratio (SER), volume transfer constant (Ktrans), rate constant (Kep), extravascular extracellular space volume fraction (Ve) and initial area under the curve (iAUC). DWI signal intensity and apparent diffusion coefficient (ADC) values were evaluated. RESULTS: Epeak, WIR, Ktrans , Kep and iAUC were higher and TTP shorter in benign compared to malignant lesions (p < 0.05). All tumours had similar ADC values (p > 0.07). Subgroup analysis limited to the most frequent histologies - Leydig cell tumours (LCTs) and seminomas - replicated the findings of the entire set. Best diagnostic cutoff value for identification of seminomas: Ktrans ≤0.135 min-1, Kep ≤0.45 min-1, iAUC ≤10.96, WIR ≤1.11, Epeak ≤96.72, TTP >99 s. CONCLUSIONS: DCE-MRI parameters are valuable in differentiating between benign and malignant small, non-palpable testicular tumours, especially when characterising LCTs and seminomas. KEY POINTS: • DCE-MRI may be used to differentiate benign from malignant non-palpable testicular tumours. • Seminomas show lower Ktrans, Kep and iAUC values. • ADC values are not valuable in differentiating seminomas from LCTs. • Semiquantitative DCE-MRI may be used to characterise small, solid testicular tumours.

The World Health Organization 2016 classification of testicular non-germ cell tumours: a review and update from the International Society of Urological Pathology Testis Consultation Panel.

The World Health Organization (WHO) released a new tumour classification for the genitourinary system in early 2016 after consensus by pathologists with expertise in these organs. It utilized the framework of the 2004 classification, and incorporated the most up-to-date information concerning these tumours. In testicular tumours, the majority of the changes occurred in the nomenclature and classification of germ cell tumours; however, several modifications were also made for non-germ cell tumours. Among sex cord-stromal tumours, sclerosing Sertoli cell tumour (SCT) is no longer recognized as a separate entity but as a morphological variant of SCT not otherwise specified (NOS), as CTNNB1 gene mutations have been noted in both neoplasms but not in the other forms of SCT. Similarly, the lipid cell variant is not separately classified, but is considered to be a morphological variant of SCT NOS. Large-cell calcifying SCT is recognized as a distinct entity that occurs either sporadically or in association with Carney complex, with the latter patients having a distinct germline PRKAR1A gene mutation. Intratubular large-cell hyalinizing Sertoli cell neoplasia is also accepted as a separate entity linked with Peutz-Jeghers syndrome. The subcategories of 'mixed' and 'incompletely differentiated' forms of sex cord/gonadal stromal tumours have been replaced by 'mixed and unclassified sex cord-stromal tumours'. New entities introduced in the latest WHO revision include: myoid gonadal stromal tumour and 'undifferentiated gonadal tissue', a putative precursor lesion of gonadoblastoma, whereas juvenile xanthogranuloma and haemangioma are included in the miscellaneous category of tumours.

Síndrome H: primer caso pediátrico reportado en América Latina / H syndrome: First reported paediatric case in Latin America

Introducción: El síndrome H es una enfermedad genética extremadamente rara de compromiso multisistémico, el cual clínicamente puede ser reconocido de forma precoz, ofreciendo de manera oportuna un seguimiento, tratamiento específico y asesoramiento genético. Objetivo: Presentar un caso con características «típicas del síndrome H¼ para favorecer su identificación precoz. Caso clínico: Varón de 8 años de edad, evaluado por tumoraciones testiculares, lesiones dérmicas tipo hiperpigmentación con hipertricosis, retraso del lenguaje, talla baja, deformidades articulares, hipoacusia neurosensorial bilateral, anemia, hipergammaglobulinemia y alteraciones óseas. En los estudios histológicos de la piel y las masas testiculares se observó infiltración linfoplasmocitaria. El secuenciamiento del gen SLC29A3 detectó una mutación homocigota c.1087 C>T (p.Arg363Trp; rs387907067) concluyente con el síndrome H, la cual ha sido reportada previamente. Conclusiones: Este es el primer caso reportado en Latinoamérica del síndrome H, cuyas características descritas son parte del espectro clínico. El hallazgo clínico principal, que orienta al diagnóstico, es la hiperpigmentación acompañada de hipertricosis.

Introduction: H Syndrome is an extremely rare genetic disease, with a multisystemic character and which can be identified in early childhood, offering the opportunity of specific treatment and genetic counselling. Objective: To present a clinical case with "typical" characteristics of H Syndrome. Clinical case: The case is presented of an 8-year-old male patient who presented with testicular tumours and skin lesions characterised by hyperpigmentation with hypertrichosis, language delay, short stature, and joint deformities. He also presented with bilateral sensorineural hearing loss, anaemia, hypergammaglobulinaemia, and bone disorders. Histopathology studies of the skin and testicular masses reported lymphoplasmacytic infiltration. Sequencing analysis of gene SLC29A3 showed the homozygote mutation c.1087 C>T (p.Arg363Trp; rs387907067). Conclusions: These findings are consistent with H syndrome, and this is the first reported case in Latin America. The key to the diagnosis is the finding of hyperpigmentation with hypertrichosis.

Malignant testicular tumour incidence and mortality trends.

AIM OF THE STUDY: In Poland testicular tumours are the most frequent cancer among men aged 20-44 years. Testicular tumour incidence since the 1980s and 1990s has been diversified geographically, with an increased risk of mortality in Wielkopolska Province, which was highlighted at the turn of the 1980s and 1990s. The aim of the study was the comparative analysis of the tendencies in incidence and death rates due to malignant testicular tumours observed among men in Poland and in Wielkopolska Province. MATERIAL AND METHODS: Data from the National Cancer Registry were used for calculations. The incidence/mortality rates among men due to malignant testicular cancer as well as the tendencies in incidence/death ratio observed in Poland and Wielkopolska were established based on regression equation. The analysis was deepened by adopting the multiple linear regression model. A p-value < 0.05 was arbitrarily adopted as the criterion of statistical significance, and for multiple comparisons it was modified according to the Bonferroni adjustment to a value of p < 0.0028. Calculations were performed with the use of PQStat v1.4.8 package. RESULTS: The incidence of malignant testicular neoplasms observed among men in Poland and in Wielkopolska Province indicated a significant rising tendency. The multiple linear regression model confirmed that the year variable is a strong incidence forecast factor only within the territory of Poland. A corresponding analysis of mortality rates among men in Poland and in Wielkopolska Province did not show any statistically significant correlations. CONCLUSIONS: Late diagnosis of Polish patients calls for undertaking appropriate educational activities that would facilitate earlier reporting of the patients, thus increasing their chances for recovery. Introducing preventive examinations in the regions of increased risk of testicular tumour may allow earlier diagnosis.

Incidentally detected non-palpable testicular tumours in adults at scrotal ultrasound: impact of radiological findings on management Radiologic review and recommendations of the ESUR scrotal imaging subcommittee.

OBJECTIVES: The increasing detection of small testicular lesions by ultrasound (US) in adults can lead to unnecessary orchiectomies. This article describes their nature, reviews the available literature on this subject and illustrates some classical lesions. We also suggest recommendations to help characterization and management. METHODS: The ESUR scrotal imaging subcommittee searched for original and review articles published before May 2015 using the Pubmed and Medline databases. Key words used were 'testicular ultrasound', 'contrast-enhanced sonography', 'sonoelastography', 'magnetic resonance imaging', 'testis-sparing surgery', 'testis imaging', 'Leydig cell tumour', 'testicular cyst'. Consensus was obtained amongst the members of the subcommittee, urologist and medical oncologist. RESULTS: Simple cysts are frequent and benign, and do not require follow up or surgery. Incidentally discovered small solid testicular lesions detected are benign in up to 80 %, with Leydig cell tumours being the most frequent. However, the presence of microliths, macrocalcifications and hypoechoic areas surrounding the nodule are findings suggestive of malignant disease. CONCLUSION: Asymptomatic small testicular lesions found on ultrasound are mainly benign, but findings such as microliths or hypoechoic regions surrounding the nodules may indicate malignancy. Colour Doppler US remains the basic examination for characterization. The role of newer imaging modalities in characterization is evolving. KEY POINTS: • Characterization of testicular lesions is primarily based on US examination. • The role of MRI, sonoelastography, contrast-enhanced ultrasound is evolving. • Most small non-palpable testicular lesions seen on ultrasound are benign simple cysts. • Leydig cell tumours are the most frequent benign lesions. • Associated findings like microliths or hypoechoic regions may indicate malignancy.

Prepubertal testicular tumours: Should testicular-sparing surgery be considered? A single-institution experience and review of the literature.

OBJECTIVES: To review our 10-year experience with uncommon testicular tumours in children (prepubertal testicular and paratesticular), to review previous reports, and to determine the appropriate management of these rare tumours, specifically the role of testicular-sparing surgery. PATIENTS AND METHODS: We retrospectively reviewed all cases of testicular tumours managed at our institution between 1999 and 2009. Boys aged <16 years were included in the study. The patients' characteristics, presentation, the diagnostic tools, tumour markers, mode of treatment, pathological findings and outcome were assessed. We reviewed previous reports that addressed testicular and paratesticular tumours in prepubertal boys, using a Medline/PubMed search. RESULTS: From 80 patients, 13 boys (median age 8.7 years) presented with testicular tumours (16%) and were included in the study. Two boys presented with precocious puberty and one with gynaecomastia. The level of α-fetoprotein was high in three boys, and the human chorionic gonadotrophin level was elevated in one, and both markers were high in one. Testicular-sparing surgery was performed in three boys. Six of the 13 tumours were malignant and seven were benign. None of the patients developed a recurrence or testicular atrophy after testicular-sparing surgery. From the review of previous reports we devised an evidence-based algorithm for managing prepubertal testicular tumours. CONCLUSIONS: Paediatric testicular tumours are rare but they require an inguinal approach for either orchidectomy or testicular-sparing surgery; we recommend the latter option as long as frozen sections are analysed and a safety margin is maintained.

Cavernous haemangioma of the testis mimicking testicular malignancy in an adolescent.

Haemangioma of the testis is a rare condition. This benign vascular neoplasm may arise either within the testicular parenchyma (intratesticular) as in this case or from adnexal structures of the testis (extratesticular). Intratesticular haemangioma is rarer than extratesticular form. Intratesticular vascular neoplasms are extremely rare tumours and mostly seen in children or young adults. There are 21 reported testicular haemangioma cases in the literature as indexed in PubMed. Since 2007, only 19 cases of cavernous haemangioma have been reported in the literature in PubMed and other indexed sites. We report a case of cavernous haemangioma of the testis to attract attention to testicular haemangioma and also to prevent invasive surgery of the testis.

Ultrasound in the detection of testicular tumours.

Ultrasonic scanning provides high resolution sectional images of the scrotal content. The value of ultrasound in the detection of testicular tumours is discussed based on the ultrasonic findings in the normal testis as well as the findings in two patients with malignant testicular tumours.
