Atypical fibroxanthoma is an uncommon tumor that usually occurs in the skin of the head and neck of the elderly with significant sun exposure. We describe a unique case featuring a rare ocular surface conjunctival tumor (atypical fibroxanthoma) and provide insight on its characteristic clinical features, surgical management, and histology.
A 71-year-old male fisherman with no pertinent ocular history presented to an academic center with a rapidly enlarging bulbar conjunctival mass in the right perilimbal region for the past several months. The patient underwent surgical excisional biopsy with cryotherapy, adjuvant alcohol, and amniotic membrane transplantation.
Pathology specimen illustrated an atypical spindle cell tumor with inflammatory cells, increased mitotic activity, cytologic atypia, and positive diffuse staining with CD163 and CD10 consistent with an atypical fibroxanthoma.
Atypical fibroxanthoma is an extremely rare ocular surface tumor that may simulate conjunctival or ocular surface squamous neoplasia. While this lesion typically pursues a benign clinical course, it may recur or rarely metastasize. Thus it should be treated aggressively with excisional biopsy, cryotherapy, absolute alcohol, and/or amniotic membrane transplantation.
