Abstract
Background: Kikuchi-Fujimoto Lymphadenitis, also known as histiocytic necrotizing lymphadenitis, is a benign, rare, and self-limiting disease that mainly affects young Asian women.
Case Report: We present a case of a 35-year-old Caucasian female with painful unilateral axillary lymphadenopathy. The patient was initially diagnosed with breast cancer based on her clinical presentation and initial pathology review of her lymph nodes.
Conclusions: However, after a series of imaging to exclude a primary neoplastic source and metastasis, and upon expert hematopathologic review of her lymph nodes, the patient was diagnosed with Kikuchi-Fujimoto Lymphadenitis.

Keywords: Kikuchi Fujimoto Lymphadenitis, necrotizing lymphadenitis, axillary adenopathy
