Fig. 2From: Simultaneous development of sarcoidosis and cutaneous vasculitis in a patient with refractory Crohn’s disease during infliximab therapy a Trans-bronchial lung biopsy (TBLB) revealed non-caseating epithelioid cell granuloma with Langhans giant cells, which were compatible with sarcoidosis (HE staining, ×400). b Anti Propionibacterium acnes antibody staining was negative within this specimen. c Skin biopsy from the right thigh shown in Fig. 1d revealed leukocytoclastic vasculitis in the superficial layer of the sub-dermal portion. (HE staining, ×100). d A high-power field of Fig. 2c revealed remarkable infiltration of neutrophils around small capillaries and leukocytoclasis. (Elastica-Masson staining, ×400)Back to article page
