Erythromelanosis Follicularis Faciei et Colli: A Case Report in a Caucasian Male and Brief Review of the Literature

The document reported a case of erythromelanosis follicularis faciei et colli (EFFC) in a 50-year-old Caucasian male, characterized by symmetrical erythematous and hyperpigmented facial lesions with follicular papules. The patient had a history of arterial hypertension and Lyme disease but no family history of dermatologic conditions. Despite treatment with topical steroids and emollients, the condition remained static. The report highlighted the rarity of EFFC, especially in Caucasians, and reviewed similar cases from the past 10 years, noting variability in clinical presentation. The etiology of EFFC is unknown, and treatment options are not well defined, though laser treatments have been used.
