Sclerosing lymphocytic lobulitis of the breast

Sclerosing lymphocytic lobulitis of the breast is an uncommon condition which clinicians need to be aware of. The disorder has characteristic pathological features; however, findings on triple assessment may be equivocal. In this paper we report ten cases of sclerosing lymphocytic lobulitis and outline the clinical, cytological and radiological features of this condition. Patients, often diabetic, typically present with discrete firm breast lumps. Fine needle aspiration cytology is either acellular or benign and mammography is normal or indeterminate whereas ultrasonography is usually suspicious of malignancy. If the condition is recognized prior to surgery, excision biopsy in patients who are often diabetic may be avoided.
