Ileocecal Mucosal Involvement of Blastic Plasmacytoid Dendritic Cell Neoplasm without Skin Lesions / 대한내과학회지

ABSTRACT

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a relatively rare hematological malignancy, and most cases present with characteristic skin lesions. The skin lesions appear as nodules, plaques, and bruise-like macules with redness or ulcerations. BPDCN without skin lesions is rare. Cases with hepatosplenomegaly, pulmonary involvement, multiple lymphadenopathies, renal masses, sinonasal sinus, and subcutaneous masses have also been reported. Here, we report the first case of ileocecal valve involvement of BPDCN without skin lesions.
