“…Adenomatoid tumors of the male (paratesticular) and female (uterus and fallopian tubes) reproductive tracts have been recognized since 1945. There have been no confirmed cases of malignant transformation and only one case report has cited the possibility 1,2 . Even with incomplete resection, no recurrence has been reported and Tammela et al .…”

Adenomatoid tumor of the tunica albuginea

Adenomatoid tumors are benign mesothelial tumors most commonly found in the paratesticular structures, especially the epididymis. Herein, we report a case of adenomatoid tumor originating in the tunica albuginea and mimicking an intratesticular neoplasm. We review the ultrasonographic presentation and literature regarding adenomatoid tumors originating in the tunica albuginea and testicular parenchyma.Key words adenomatoid, case report, review, testes, tumor, tunica albuginea. Case reportA 44-year-old African-American male presented with a 1 year history of a right midtesticular mass which had progressively enlarged over the last 3 months. He denied having any urinary or constitutional symptoms. On physical examination, his testicles were descended bilaterally with a nodule noted in the midposterior aspect of the right testicle. His physical examination was otherwise unremarkable. Serum tumor markers including b -human chorionic gonadotropin, a -fetoprotein and lactate dehydrogenase were normal. Scrotal ultrasonography was performed, revealing a right testicular mass (Fig. 1).The patient underwent exploration via a right inguinal approach. After isolating the spermatic cord, an excisional biopsy was sent for intraoperative frozen section analysis (Fig. 2). These sections were suggestive of an epithelial neoplasm, though malignancy could not be excluded. A right radical orchiectomy with high ligation of the cord was therefore performed. Final pathological analysis showed mesothelioid cell invasion from the tunica albuginea into the testicular parenchyma. The tumor cells were positive for CK7 and tumor cell nuclei stained darkly with calretinin (typical of mesotheloid subtype adenomatoid tumors). The tumor itself measured 0.7 ¥ 0.6 ¥ 0.5 cm with clear margins (Figs 3,4).

“…1,2 They often present as a hard painless mass and have been reported between the third and seventh decades. [1][2][3] Adenomatoid tumours are believed to be of mesothelial origin as supported by immunohistochemistry and ultrastructural studies. 4,5 Ultrasonography remains the imaging of choice for the initial investigation of testicular lesions.…”

We describe the case of a 65 year-old male presenting with a tender right testicular mass, confirmed to be a tumour on ultrasound. The patient underwent a radical inguinal orchidectomy and histology revealed multiple adenomatoid tumours in epididymis and tunica vaginalis. This is an infrequent benign tumour of mesothelial origin that has rarely been reported as multiple lesions in the literature. Immunohistochemistry demonstrates that adenomatoid tumour and mesotheliomas share the expression of podoplanin (D2-40) which is helpful to differentiate them from carcinomas. On the other hand adenomatoid tumour is differentiated from mesothelioma on morphological grounds since the former does not exhibit cellular atypia, mitotic activity or bland focal tumour necrosis. Although testis preserving surgery can be an option for benign adenomatoid tumours, most patients (as in our case) proceed to orchidectomy as diagnosing them confidently can be difficult.

“…Tedavisinde kitle enükleasyonundan ibaret testis koruyucu cerrahi yeterlidir (6). Tam rezeksiyon sağlanamayan olgularda bile rekürrens gelişmediği bildirilmiştir (10). Bu nedenle özellikle fertil çağdaki bireylerde gereksiz orşiektomileri önlemek amacıyla, tanısal açıdan şüpheli vakalarda intraoperatif frozen section yöntemi kullanılmalıdır (2,5,6).…”
