Soft tissue chondroma (STC), also known as extraskeletal chondroma or chondroma of soft parts is a benign cartilaginous tumor which arise de novo from soft tissue. Also, it is an extremely rare entity predominantly involving extremities, especially fingers. A 26 year old male presented with 3 year history of swelling in left index finger. On local examination a hard 2 × 2 cm swelling was seen over the volar aspect of left 2nd proximal phalanx. Swelling was mobile on contraction of tendons. X-ray showed a soft tissue shadow on volar aspect of left second proximal phalanx. Histopathology showed a well encapsulated, hypo cellular nodule composed of benign chondrocytes surrounded by hyaline chondroid matrix. Nuclear pleomorphism, mitosis or necrosis was not seen. Based on radiological and histopathological findings a diagnosis of STC was made. STC should be considered in patients with slow growing, soft tissue masses.
