丘疹性弹力纤维溶解性巨细胞肉芽肿经窄波UVB照射治疗获缓解

摘要

cqvip: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 multi-nucleated 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 ultraviolet B irradiation, with only residual brown pigmentation left after treatment.
