A 51-year-old man was referred at the urological department due to the primary suspicion of a left testicular cancer. Staging computed tomography of the thorax, abdomen, and pelvis was negative for lymphatic or hematogeneous metastatic tumor spread. Moreover, testicular tumor markers such as α-fetoprotein (AFP) and beta-human chorionic gonadotropin (β-hCG), and preoperative hormone levels (testosterone, LH, FSH) were within normal ranges.\nTesticular ultrasound confirmed a 0.9 × 0.9 × 1.0 cm rounded, peripheral, and hyperechoic lesion of the lower pole of the left testicle (Fig. a) connected with the tunica albuginea, without pathological signs of the right testicle. No exact vascular signs or vascular flow within this lesion were reproducible on baseline color and power Doppler sonography (Fig. b). Contrast-enhanced ultrasound (LOGIQ E9 ultrasound machine by GE Healthcare, Fairfield, Connecticut, USA) was performed as an additional diagnostic tool to clarify the vascularization of the suspicious lesion. Interestingly, the lesion was contrast-absorbing after bolus contrast agent application of 2.4 cc (SonoVue, Bracco, Milan, Italy), Fig. c. Moreover, real-time elastography (RTE) of the left testis was performed to evaluate the tissue elasticity of the tumor mass, showing a hard lesion (Fig. d). In summary, multiparametric ultrasound confirmed a vascularized and hardened lesion, therefore being suspicious of testicular cancer.\nNext, inguinal exploration with organ-sparing surgery and tumor enucleation was performed without ischemia. Intraoperative frozen section analysis of the tumor and tumor bed biopsies was performed, providing no evidence of malignant germ cell tumor or testicular intraepithelial neoplasia (TIN). Final pathology report confirmed a completely removed adenomatoid tumor of the left testicle arising from the tunica albuginea.
A 30 year-old male presented with a right-sided, tender scrotal swelling of four days’ duration. He had no significant past medical history or history of trauma. On local examination, a firm, mobile, and tender mass measuring 2 × 2 cm was found; the contralateral testis was normal. A clinical diagnosis of tuberculous epididymitis or testicular neoplasm was made. Routine hematological and biochemical investigations, urine analysis, and a chest radiograph revealed no abnormalities. USG of the scrotum showed a well defined, hypoechoic mass measuring 2.5 × 2 cm in the region of the globus major of the right epididymis. Aspiration was done using a 10 mL syringe and a 24 gauge needle to yield a scanty, grey-white aspirate. The smears were stained with H and E, Papanicolaou, and MGG stains. The cytological features were similar as those of case 1 and a diagnosis of an adenomatoid tumor was made. The patient underwent a conservative testis-sparing surgery with the excision of the epididymal nodule. The nodule measured 2 × 2 cm and the cut section was grey-white with microcysts. The results of the histopathological investigation were consistent with features of an AT.
