Cutaneous histoplasmosis is an uncommon infection and can occur as a primary infection. A manifestation imitating a cutaneous neoplasm is rare, and eyelid involvement is rarer still. The authors report a case of histoplasmosis that presented as an ulcerated lesion on the lower eyelid margin that clinically resembled a basal cell carcinoma. Given its worldwide distribution, it is important to include this disease in the differential diagnosis of nonhealing eyelid lesions. Biopsy and tissue culture are paramount to establishing the diagnosis. This case describes a rare presentation of histoplasmosis on the eyelid and highlights the importance of histopathologic evaluation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
