Sclerosing lymphocytic lobulitis of the breast is an uncommon conditio
n which clinicians need to be aware of. The disorder has characteristi
c pathological features; however, findings on triple assessment may be
equivocal. In this paper we report ten cases of sclerosing lymphocyti
c lobulitis and outline the clinical, cytological and radiological fea
tures of this condition. Patients, often diabetic, typically present w
ith discrete firm breast lumps. Fine needle aspiration cytology is eit
her acellular or benign and mammography is normal or indeterminate whe
reas ultrasonography is usually suspicious of malignancy. If the condi
tion is recognized prior to surgery, excision biopsy in patients who a
re often diabetic may be avoided.
