A case of primary chondrosarcoma of the testis is reported. A 40-year-old man presented a painless swelling of the right testis that he has been observing for 3 years. Gross examination of the resected specimen showed an encapsulated, gray to tan colored, roughly rounded tumor. Histologically, the tumor revealed a well-differentiated chondrosarcoma.
words: testis; testiculat neoplasms; chondrosarcoma
Although extra-skeletal cartilaginous neoplasms are rare, chondroid differentiation of teratomatous tumors of the testis is common. Benign cartilaginous component can be found in about 75% of mature teratomas and 54% of malignant teratomas of the testis. Primary intratesticular chondrosarcoma is extremely rare. We report a case of a testicular chondrosarcoma.
A 40-year-old man was admitted to the hospital with a painless mass in the right scrotum. The mass had been present for 3 years. The left testis was normal. There was no history of trauma to the testis or any other significant previous illness, such as mumps or venereal disease. Physical examination revealed an otherwise healthy man. A biopsy of the mass was performed and a diagnosis of testicular malignant neoplasm was made. A right orchiectomy was performed.
Although primary malignant mesenchymal tumors of the testis are rare, chondroid differentiation of teratomatous tumor of the testis is not. Five percent of all teratomas of the testis are well differentiated, and nearly 75% of these tumors contain cartilage elements. Pure cartilaginous tumors of the testis are extremely rare (1). In literature, Dounis described a chondroma (2) and Fuzesi et al. reported a metastasizing primary testicular chondrosarcoma (3). The former case was reported to be fit and well with no evidence of metastasis 2 years after definitive surgery, and the latter was reported to be in remission 36 months after surgery. The present case is the second testicular chondrosarcoma reported in English literature, and likewise the formerly reported case, the patient is well 25 months afteroperation.
