A Case of Linear Lupus Erythematosus Profundus on the Scalp Presenting as Alopecia

We present a case of a young male with a five year history of a hair-loss patch presenting linear distribution on the scalp. A biopsy specimen revealed a lymphocytic panniculitis and fat degeneration with mucin deposit. Focal hydropic degeneration of basal cells was also evident. Direct immuno-fluorescence revealed peribulbar granular deposits of IgM, IgA and C3. Antinuclear antibody was negative. Clinical appearance was unusual but histological examination revealed linear lupus erythematosus profundus. To our knowledge, only one other case of linear lupus erythematosus profundus on the scalp has been reported in English written literature until now.
