Purpura Annularis Telangiectodes (?). Presented by Dr. Leon Reznick and Dr. Maurice M. Tolman, Boston.
M., a 33-year-old Italian-American leather worker, has had an eruption for two years in the bathing-trunk area. The lesion starts as an area of erythema, a few millimeters in diameter, which then grows to a size of 1 cm. or more, becoming slightly scaly and raised. Soon the center fades to brown, while the periphery shows a collarette of tiny, erythematous papules. Eventually, the papules also fade, the whole process taking about four weeks. The patient presents lesions in all stages of development.
Biopsy showed chronic inflammatory changes, with a patch of infiltrate in the upper corium.
Dr. Alfred Hollander, Springfield, Mass.: I would like to propose a diagnosis of lichen planus annularis, although the histological specimen I saw is not compatible with that diagnosis.
Dr. Walter F. Lever, Boston: I agree with the thesis
