Diabetic fibrous mastopathy, also known as lymphocytic mastitis, is an
uncommon lesion of the breast that occurs in women with long-standing
insulin-dependent diabetes mellitus (IDDM). To my knowledge, the fine
-needle aspiration findings of a histologically confirmed case of diab
etic fibrous mastopathy have not been previously described and illustr
ated in the cytology literature. (C) 1993 Wiley-Liss, Inc.
