Primary Fibrosarcoma of the Testicle with Puzzling Post-surgery Presentation: Mimicking Recurrence

摘要

Sarcomas of the testis are extremely rare tumors, their incidence being difficult to assess accurately. The authors report a case of a 21-year-old male, presented with painless scrotal swelling that increased in size insidiously within three months. The examination revealed a 10 cm right testicular swelling—hard, not tender and oval in shape. Testicular ultrasound revealed right heterogenous testicular mass. Tumor markers (Human chorionic gonadotrophin (HCG) and alpha fetoprotein) were normal. CT chest and abdomen were normal. Radical orchidectomy was done through an inguinal approach. Histopathology showed testicular fibrosarcoma with spindle cells. After one month, the patient noticed reappearance of a swelling in the right hemiscrotum. Right inguinal exploration with massive resection of the recurrent scrotal mass was done. Histopathology revealed inflammatory process dominated by stitch granuloma. In conclusion, the recurrence rate of testicular sarcomas is high following radical orchidectomy, but still there was a place of non-malignant mass that looks like recurrence; it might occur like nonspecific inflammatory mass and stich granuloma.
