Adenomatoid tumour of testis

An incidental finding of large cell calcifying Sertoli cell tumor in an orchidectomy specimen for a separate adenomatoid tumor

Introduction

Large cell calcifying Sertoli cell tumors are exceedingly rare. They are most commonly benign, but risks for malignancy include older age, larger size of tumor, and solitary tumors. To the author's knowledge, this is the first case reported of an incidental large cell calcifying Sertoli cell tumor when an orchidectomy was performed for a separate lesion.

Case presentation

A 31-year-old male presented with a painless testicular lump. Ultrasound demonstrated an exophytic lesion in the superolateral aspect and calcifications were noted inferomedially and inferolaterally in the right testis. On histology from radical orchidectomy, the superolateral lesion was found to be an adenomatoid tumor, and the calcifications inferiorly represented a large cell calcifying Sertoli cell tumor. The background showed foci of germ cell neoplasia in situ but no evidence of invasive malignancy.

Conclusion

Calcifications on ultrasound in isolation may represent large cell calcifying Sertoli Cell tumors.

Epididymal adenomatoid tumor: a case report and literature review

Background

Adenomatoid tumor is a very rare benign neoplasm of mesothelial origin affecting mainly female and male genital tracts. The diagnosis is challenging as this tumor mimics many differential diagnoses. The current literature offers only some case reports and short series of adenomatoid tumors.

Case presentation

A 47-year-old patient with unremarkable medical history presented for chronic mild pain of the right testis evolving for months. The physical examination shows a palpable right intrascrotal nodule of 10 mm in greatest diameter. The nodule was painful, mobile with firm consistency. The laboratory investigations were within normal limits, the scrotal ultrasonography showed a well-circumscribed predominantly hyperechoic intrascrotal nodule in the right epididymal head with heterogeneous echostructure. Excisional biopsy of the lesion was performed and the histopathological analysis showed a well-circumscribed tumor with microcystic and trabecular architecture made of small interconnected tubules and cysts lined by flattened cells with prominent vacuolization and thread-like bridging strands, consistent with an epididymal adenomatoid tumor. The postoperative course was uneventful and the patient was discharged. Four months after surgical treatment, the patient has no sign of the disease.

Conclusion

Testicular adenomatoid tumors are uncommon benign neoplasms with diagnostic challenge. Adenomatoid tumors arising in epididymis are managed by excisional biopsy with testis-sparing surgery avoiding unnecessary orchidectomy.

Adenomatoid Tumor of the Testis Arising From the Tunica Albuginea

Adenomatoid tumors are the most common paratesticular tumor. Although they primarily arise from the epididymis, they can rarely occur as an isolated intratesticular mass. These tumors are benign and surgical excision is curative. We present a case of a 36-year-old man diagnosed with an intratesticular adenomatoid tumor.

Adenomatoid tumors of the testis: A report of two cases and review of the literature

Adenomatoid tumors are rare benign neoplasms that normally occur in the scrotum. The clinical symptoms and routine examinations mean that it is difficult to distinguish adenomatoid tumors from malignant intratesticular solid tumors, which may result in unnecessary orchidectomies. The present report describes two adenomatoid tumor patients treated between 2006 and 2013 at the Peking University Shenzhen Hospital who presented with an asymptomatic mass in the scrotum. Based on thorough analysis of clinical features, blood, radiological images and intra-operative findings, limited local excisions were performed, revealing adenomatoid tumors of the testis on pathological examination. The patients were followed up and exhibit no recurrence at the time of writing. The present report also summarizes the morphological and immunohistochemical features of paratesticular tumors and reviews the literature to improve understanding of these rare lesions and assist in accurate diagnosis.
