Orbital Myiasis Complicating Squamous Cell Carcinoma in Xeroderma Pigmentosum

Abstract

Ophthalmomyiasis is a rare infection seen in susceptible individuals. We report a case of orbital myiasis in squamous cell carcinoma (SCC) in a patient of xeroderma pigmentosum. On presentation, reddish brown ulcerated mass with numerous maggots in orbit were seen. Computed tomography scan showed the presence of soft tissue lesion without any bony destruction. Following debridement, emergency exenteration with sacrifice of eyelid skin was performed. The diagnosis of SCC was confirmed on histopathologic evaluation. The maggots belonged to family Calliphoridae and secondary bacterial infection with Klebsiella organism was identified. Management issues included extensive involvement requiring exenteration, non-availability of skin graft, delayed secondary healing and recurrence of pigmented lesions in skin lining of orbit. The skin grafting was avoided as it can harbour the neoplasm.
