海报摘要

Generalized form of multinucleate cell angiohistiocytoma is an exceedingly rare entity and mainly affects face, upper trunk and extremities. The most characteristic histopathologic features include a proliferation of small-sized capillary-type vessels in the superficial and mid dermis intermingled with sparse multinucleated fibrohistiocytic cells and lymphocytes, and dermal fibrosis with thickened collagen bundles. Dermatologists and pathologists should be aware of the generalized form of this entity and consider it in the differential diagnosis of maculopapular rashes that mainly involve upper chest and extremities. The clinicopathologic correlation and recognition of this variant remains essential to differentiate it from other mimickers.
