Abstract

PURPOSE
To report a case of orbital chondroma. CASE SUMMARY: A 15-year-old male presented with an 8-month history of left hypertropia. The best-corrected visual acuity was 20/20 in both eyes. The exophthalmometry showed no exophthalmos, with 13 mm in both eyes. There was a hard palpable mass at the superonasal orbit of the left eye. Orbital computed tomography showed a heterogenous soft tissue shadow at the superonasal orbit of the left eye, and orbital magnetic resonance imaging revealed a 25 × 16 × 20 mm well-defined mass with low signal intensity in the T1-weighted image, high signal intensity in the T2-weighted image, and heterogenous enhancement in the contrast enhanced T1-weighted image. The mass was surgically removed with anterior orbitotomy. A 27 × 17 mm well-capsulated lobular mass was found, and histopathological examination revealed hyaline cartilage and chondrocyte. The mass was diagnosed as a chondroma. CONCLUSIONS: A chondroma is a benign tumor, which usually occurs in long bones and the small bones of the hands and feet. It is very rare in the facial and pelvic bones. The sites of chondroma occurring in the head and neck include the ethmoid sinus and maxilla, but it is extremely rare in the orbit.
