A Case for Diagnosis: Foreign Body Reaction? Tuberculoid Reaction? Sarcoid? Presented by DR. FRANCES PASCHER and (by invitation) DR. OTTO B. HITSCHMANN.
A 5-year-old white girl was first seen at the Skin and Cancer Unit two months ago with lesions of five months' duration.
On the left side of the chin, 1 cm. beneath the lower lip, running to the upper part of the same side of the neck, the patient presents a well-circumscribed, erythematous lesion with papulovesicular elements in linear configuration.
A Moro contrast test on each side of the chin (both the affected and unaffected) was negative.
A biopsy showed the following: The corium presents a diffuse and focal cellular reaction composed of small round and wandering connective tissue cells. In some areas there are nests of epithelioid cells. The epidermis is markedly acanthotic and flattened in some areas. The vessels throughout are dilated.
