Scrotal extraosseous chondroma: Case report of an exceedingly unusual presentation and review of the literature

Abstract

We report an exceedingly rare case of scrotal extraosseous chondroma in a 63 year-old man that presented with a recently growing scrotal mass. The mass was excised and broke into three tan-white firm nodules ranging in size from 1.0 to 1.5 cm in greatest dimension. Histologic examination showed mature hyaline cartilage and the case was diagnosed as extraosseous chondroma. Except for those arising in the hands and feet, extraosseous chondromas are rare benign tumors that arise in tissue unrelated to bone. Only eight extraosseous chondromas have been reported in the pelvis, six of them in females, while both male cases have been in the prostate and testis. We present the third case of extraosseous chondromas in the male pelvis, first reported in the scrotum.
