“…Cystic and extratesticular lesions are suggestive of benign pathology. Adenomatoid tumors of the tunica are frequently oval shaped, while those of the epididymis are usually round and homogenously echogenic 9,10 . Feuer et al .…”

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).

“…Adenomatoid tumors are usually found incidentally by the patient or by a physician at physical examination. Characterized as a painless firm scrotal mass, an adenomatoid tumor is a benign neoplasm with no reported metastases or recurrence after excision (67). The US appearance varies from hypoechoic to hyperechoic to isoechoic, compared with adjacent tissues.…”

Ultrasonography (US) with a high-frequency (7.5-10-MHz) transducer has become the imaging modality of choice for examination of the scrotum. US examination can provide information valuable for the differential diagnosis of a variety of disease processes involving the scrotum that have similar clinical manifestations (eg, pain, swelling, or presence of mass). The pathologic condition that may be at the origin of such symptoms can vary from testicular torsion to infection to malignancy. The ability of color and power Doppler US to demonstrate testicular perfusion aids in reaching a specific diagnosis in patients with acute scrotal pain. This review covers the anatomy of the scrotum and the scanning protocol for scrotal US, as well as detailed descriptions of disease processes and their US appearances. Newly described conditions such as intratesticular varicoceles and other benign intratesticular cystic lesions are also discussed.

“…Spermatoceles are large cystic dilatations of the ductal system also most commonly arising in the epididymal head; they are more common after vasectomy and are only distinguishable from simple epididymal cysts by the low‐level echoes generated by spermatic debris within the spermatocele. Most solid epididymal lesions are benign and include adenomatoid tumours and lipomas [18–20]. Typical features are homogenous lesions with well‐defined margins and low vascularity on Doppler imaging.…”
