Sonographic Features of an Adult Granulosa Cell Tumor of the Testis

Adult granulosa cell tumour of the testis: an uncommon tumour

A male patient in his late 20s was admitted to the hospital after presenting with left abdominal, back and scrotal pain that had begun approximately 2 weeks earlier. He had a history of a stable left testicular mass for 3 years, and a physical exam revealed a non-tender, firm left testicular mass and a mild left varicocele. Testicular tumour markers were normal, but a scrotal ultrasound revealed a 2 cm hypoechoic left testicular lesion. Staging imaging showed no retroperitoneal adenopathy or pulmonary metastases.The patient underwent left radical inguinal orchiectomy with no evidence of extratesticular or spermatic cord involvement. His surgical pathology revealed a left pT1a 2.3 cm adult granulosa cell tumour of the testis with no lymphovascular invasion. The tumour was positive for inhibin and negative for OCT3/4, supporting the diagnosis.

Adult Granulosa Cell Tumor of the Testis: A Case Report with a Review of the Literature

Adult granulosa cell tumor (AGCT) of the testis represents a very rare testicular neoplasm that is poorly understood clinically. Here we report the case of a 22-year-old male who presented with unspecific scrotal symptoms. Scrotal sonography disclosed a 6 mm hypoechoic intratesticular lesion. Histological examination after orchiectomy revealed a homogeneous and well demarcated neoplasm with monomorphic cells with nuclear grooving and microfollicular formation of the so-called Call-Exner bodies. Immunohistology showed positive stainings of vimentin, calretinin, and inhibin with negative stainings of the typical germ cell tumor markers. Thus, the diagnosis of a benign AGCT was made. The patient is well one year after surgery. A total of 91 previous AGCT cases were identified in the literature. Median age of the cases reported to date is 44 years, median tumor size 3.2 cm. 54.3% of the AGCT cases were located on the left side. 12 cases (13.2%) were of malignant nature. Testis-sparing surgery would be the treatment of choice, but only two of all cases had received that procedure. The present report aims to increase the clinical knowledge of AGCT and specifically to increase the clinician's vigilance with respect to testis-sparing surgery in probably benign testicular masses.

Adult type granulosa cell tumor of the testis: Radiological evaluation and review of the literature

A testicular granulosa cell tumor of the adult type is very rare. Isolated case reports and small series have been published in the English literature. Here, we analyze an incidentally discovered testicular granulosa cell tumor in a 29-year-old man to discuss the radiological evaluation of this entity and review the literature.
