Regression of papular elastolytic giant cell granuloma using narrow-band UVB irradiation.
A 71-year-old Japanese man presented with asymptomatic, firm, brown-red papules on the dorsum of his left hand and back. A biopsy specimen revealed granulomatous infiltration consisting of multinucleated giant cells and histiocytes in the upper dermis. Elastic fibers were absent in the upper dermis, having been phagocytosed by giant cells. These papular elastolytic giant cell granuloma lesions regressed very well with narrow-band ul traviolet B irradiation, with only residual brown pigmentation left after treatment.
