Orbital Myiasis in Basal Cell Carcinoma

Abstract

Cases of orbital myiasis are rare in the world because the eyeball is a rare and exceptional site for infestation by dipteran fly larvae. A clinical case of a patient with this condition is presented. The patient was a 59-year-old male, a farmer from a rural area, who came for consultation because he presented intense pain in the eyelid, tingling sensation, red eye and tearing in the left eye after suffering a trauma in a lesion located in the lower eyelid on that side, which he reported had been evolving for years and had increased in size over time. Serohematic secretion, conjunctival ciliary injection and intense chemosis were observed in the left eyeball, in addition to marked edema and tumefaction with central ulceration, tissue necrosis and the presence of larvae of approximately 10 mm; Therefore, a diagnosis of cutaneous myiasis of the left lower eyelid was made and a biopsy confirmed a basal cell carcinoma in the lesion located in the same site, for which she received surgical treatment after the resolution of the septic picture. Myiasis is a rapidly evolving, high-risk disease that is closely related to the hygienic-sanitary and environmental conditions surrounding the individual. Treatment includes mechanical removal of the larvae promptly and with extreme care, as well as prophylactic treatment to avoid complications.
