Photolocalized tinea facialis.
The case of a 34-year-old white woman with tinea facialis that persisted for nine months prior to diagnosis is presented. The confluent plaquelike erythematous eruption of the face with eyelid lichenification that flared outdoors was thought to represent polymorphic light eruption and was refractory to antibiotics, corticosteroids (topical and systemic), and antimalarials. A KOH preparation was positive when the dermatosis spilled onto the mandibular region, and restaining of the initial skin biopsy revealed fungal hyphae. Complete resolution was accomplished with griseofulvin and MicTin. Tinea cab be added to the list of infectious agents that have a photosensitivity component. The fungus possibly "photolocalizes" to sun-damaged areas, ie, areas of increased capillary permeability. This case illustrates the importance of including tinea in considering diagnoses of sun-exposed lesions of the face.
