Lipogranuloma of the Head and Neck

Objective: To report a rare case of lipogranuloma of the head & neck. Case Report: We present a 33-year old female patient with a 2-month history of left neck mass refractory to antibiotic therapy. Laboratory workup and fine needle aspiration biopsy was nondiagnostic. Excisional biopsy revealed histologic evidence of a granulomatous soft tissue reaction consistent with lipogranuloma. Lipogranul...

Relation between lipogranuloma formation and fibrosis, and the origin of brown pigments in lipogranuloma of the canine liver

However, the pathogenesis of the lesion remains unclear. Kupff...
