Exuberant clinical presentation of probable Malassezia folliculitis in a young nonimmunosuppressed patient.

Malassezia folliculitis is an inflammatory disorder observed in both immunocompetent and immunosuppressed patients. The authors describe an unusual and exuberant presumed case affecting the face, trunk and upper limbs of a 12-year-old nonimmunosuppressed patient. Although the agent was not identified by culture, the clinical and histopathological aspects plus the response to specific treatment support the diagnosis of Malassezia folliculitis.

Case for diagnosis.

We report the case of a 58-year-old white female with Parkinson's disease. She evolved to an extensive livedo reticularis in the limbs and abdomen after commencing treatment with amantadine. We discuss the diagnostic approach to livedo reticularis and its differential diagnoses, emphasizing that the drug etiology must be considered when investigating livedo reticularis.
