Lupus panniculitis (profundus) involving the breast: report of 2 cases and review of the literature.

Abstract

Breast involvement with lupus panniculitis has been infrequently reported. We describe 2 cases with breast involvement proven by biopsy to be lupus panniculitis. Our review emphasizes the clinical presentation of lupus panniculitis with mastitis and its possible clinical similarity to malignancy. In addition, other connective tissue diseases and vasculitis with breast involvement are noted.
