A Rare Case of Soft Tissue Osteoma of Hand

Osteomas are benign, slow-growing, differentiated tumours, which are primarily located in the region of maxillofacial skeleton. Osteoma involving the soft tissues with no bony attachments is a very rare event. A 68-year-old woman with comorbidities (diabetes mellitus type II, primary hypertension, pacemaker in situ) presented with a painless solid mass in the thenar region of her right palm, which appeared almost 1 and half years ago and showed a progressive enlargement in the last few months. Under regional anaesthesia, an excisional biopsy was performed and the histopathological evaluation of the lesion confirmed the diagnosis of soft tissue osteoma. The postoperative follow-up period was uneventful without any complication.
