Diabetic fibrous breast disease: description of a case with bilateral involvement and gradual spontaneous regression

We describe the clinica, radiologica and histopathological features of this rare bening breast disease in a 28-year-old patient with a long-standing history of insulin-dependent diabetes mellitus. The patient presented bilateral breast masses, mammography revealed dense breast and ultrasound demonstrated the presence of bilateral anechoic masses with irregular borders and posterior acoustic shadowing. Fine needle aspiration biopsy yielded and amorphous, a cellular hyaline-like material. The histological analysis of surgical biopsy specimens from both breast revealed the presence of keloid fibroblast with lymphocytic lobulitis. The clinical and histological findings suggested the diagnosis of the diabetic fibrous breast disease. Over 8 years of clinical follow-up the masses were seen to regress spontaneously. We confirm the findings reported previously in the literature. suggesting that those patients who fulfill the clinical cytological and imaging criteria for diabetic fibrous breast disease can be managed by clinical means, avoiding the need for surgical biopsy.
