Abstract

Summary

Churg Strauss granuloma (cutaneous extravascular necrotizing granuloma) is a distinct entity which is associated with systemic immunoreactive or autoimmune diseases in a majority of cases. Typically, Churg Strauss granuloma presents as symmetrical papules or nodules on the extremities. There are two histological patterns: the classic pattern reveals palisading granuloma with central degenerated collagen, interspersed polymorphonuclear leukocytes, and leukocytoclastic debris; the focal basophilic necrosis pattern does not show palisading granuloma. We report two cases of Churg Strauss granuloma with different histopathological patterns.
