Chondroblastoma-like chondroma of the hand: case report

Abstract

Chondroblastoma-like chondroma is a rare tumor that almost exclusively manifests in the hand and presents with a set of unique diagnostic features. This tumor has been described in only a limited number of publications and is thus commonly omitted in the differential diagnosis of hand tumors. The diagnostic imaging and histological specimens may initially appear consistent with a number of relatively more common hand tumors, thereby delaying the diagnosis. We present the case of a 49-year-old woman with chondroblastoma-like chondroma of the hand treated with marginal excision. The physical examination, imaging, and needle biopsy made an initial case for giant cell tumor of tendon sheath until histological analysis of the excised specimen yielded the correct diagnosis.
