A 12-year-old boy presented to the andrology department in June 2013 with left testicular pain that he had had for 6 months. There was no history of recent trauma, infection, hydrocele, or undescended testis. He denied having any urinary or constitutional symptoms. Physical examination revealed a hard, tender, 10 mm × 10 mm × 8 mm testicular nodule in the superior aspect of the left testis. The contralateral testicle was normal.\nScrotal ultrasonography (8 to 12 linear array transducer, LOGIQ P5, GE Healthcare, New York, New York State, USA) revealed 8 mm × 10 mm, hypoechoic homogeneous solid mass with unclear margin at the junction of the epididymis and left testis (). Serum tumor markers, including alpha-fetoprotein, beta-human chorionic gonadotropin, and lactate dehydrogenase, were all within normal limits. All preoperative laboratory tests, including complete blood count, biochemistry, and chest X-ray, were normal. A pelvic computerized tomography (CT) scan was negative for retroperitoneal metastasis. The provisional diagnosis was paratesticular tumor, with the possibility of benign nature.\nThe patient was then referred to our institution for surgical treatment. The left inguinal approach was established and the left spermatic cord was identified. On visual inspection, the tumor arose from the tunica albuginea protruding into the testis parenchyma. Intraoperative frozen-section biopsy showed benign tumor from tunica albuginea. Subsequently, a right tumor resection including removing a portion of tunica albuginea was performed.\nFinal histological examination confirmed the diagnosis of AT from the tunica albuginea (). Immunohistochemical analysis revealed the tumor cells were positive for calretinin, cytokeratin, and vimentin (). The postoperative course was uneventful. After 12 months of follow-up, the patient was asymptomatic without any evidence of local recurrence.
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.
