? Sarcoidosis. Presented by G. Robert Baler, MD.
For four years a 35-year-old white man has had an asymptomatic eruption involving the scalp, particularly at the hairline. Use of scalp or hair preparations was denied. His general health had been excellent although in the latter months of 1969 he had trigeminal neuralgia, which has since subsided.A raised, reddish-tan, infiltrated granulomatous eruption extended in a wavy line about the frontal hairline and in a circinate pattern into the frontal part of the scalp. The right anterior part of the lesion has healed without apparent scarring. There is a slightly depressed scar at the frontal hairline just posterior to the extending ridge.A biopsy specimen showed epidermal hyperplasia and granulomatous inflammation, with foci of central caseous necrosis surrounded by histiocytes, lymphocytes, and a few plasma cells and giant cells of the foreign-body type.
