کندروم نسج نرم: گزارش موردی

Background: Soft tissue chondroma is a rare slow-growing benign cartilage forming tumor. Tumors of this kind arise from the relative mesenchymal tissue and have tendency to occur in the fingers and toes. Due to its rarity, this tumor is likely to go undiagnosed. Histopathological examination usually reveals the correct diagnosis. Case presentation: Hereby, we report a case of soft tissue chondroma in a 27 year-old woman presented with a slow-growing mass in the volar aspect of her right hand. The tumor had developed over a 7-month period. The skeletal system was unremarkable on X-ray evaluation. The lesion was excised and the histopathological findings revealed a well-delineated cartilaginous neoplasm with lobular pattern. The tumor was composed of mature chondrocytes without atypia and the findings were compatible with chondroma. Conclusion: There are various hypotheses about the etiology of soft tissue chondromas and their microscopic findings are variable. They have a good prognosis. Recurrence is rare and malignant transformation has not been reported yet.
