Аннотация
BACKGROUND: The adult granulosa cell tumor of the testis is a rare sex-cord/stromal tumor, with a potentiality for late recurrence and metastasis. Because of its rarity, this tumor is poorly understood, particularly in terms of its molecular features. As a result, it is necessary to register each occurrence in order to study the evolution of this rare malignancy and develop therapeutic strategies.
METHODS: A 50-year-old man discovered a painless right testicular mass unexpectedly, and the mass steadily expanded for 2 months. Ultrasonography showed a 5.2 cm × 4.0 cm × 3.6 cm mass in the right testicle. A right radical orchiectomy was performed on September 7, 2016. The pathologic diagnosis was a testicular adult granulosa cell tumor. The post-computed tomography scans and bone scintigraphy ruled out distant metastases. A high-throughput sequencing of 520 cancer-related genes revealed FOXL2 C134W, CDKN2A E87Gfs*24, TP53 S183*, TERT c.-124C > T, and H3F3A K28R mutations in this case. Because the patient stated he would be unable to return to the hospital for a follow-up appointment on time, he elected to have 4 cycles of adjuvant chemotherapy BEP (bleomycin, etoposide, and cisplatin) after the right radical orchiectomy.
RESULTS: The patient has not had a clinical recurrence or metastasis in 6 years.
CONCLUSION: Surgery together with adjuvant chemotherapy may be useful treatment options for these individuals with malignant tendencies who are unable to visit the hospital for a follow-up appointment on time. Adult testicular granulosa cell tumors have a relatively complex genetic profile; their etiology is linked to a number of common driver genes, including TERT, CDKN2A, TP53, and H3F3A.
