Subungual chondroma in a teenager.

Soft tissue chondroma is a rare benign tumor that occurs more often in the distal limbs and is unattached to the underlying bone. An 11-year-old boy, presented with a nodule of the subungual area of the right big toe. Objectively, the nail plate was partially destroyed owing to protrusion. Digital dermoscopy revealed yellow keratinous masses in the subungual area, with fibers adhering to the surface. Post-traumatic hemorrhages were observed in the tumor. Owing to functional discomfort, the patient underwent removal of the mass under local anesthesia. The histological picture is consistent with subungual soft tissue chondroma. Subungual soft tissue chondroma is more common in adults, but can affect people of all ages.
