Diabetic mastopathy is a recently described collection of radiographical and histological features found in dense fibrous masses of the breast in long standing Type I diabetes. We describe the first case of bilateral disease with the alternate progression and regression of the disease over a 5 year period. A 45-year-old woman has been affected of insulin dependent diabetes mellitus (IDDM) for 21 years. She developed palpable mass retromamillar of the right side, indistinguishable radiographically from cancer. The histology showed a diabetic mastopathy (DMP) with B-lymphocytic ductitis and lobulitis, a discrete monocellular vasculitis and a keloid-like fibrosis. After 22 months she developed a suspicious palpable mass contralateral on the left side. The FNAB presented an identical morphology on histology. Additionally 10 months later there were no palpable masses of both mammae. Mammographically no suspect alterations were observed. One year later the clinical and mammographical examination showed similar findings, mentioned before. The pathogenesis is still obscure and includes the hypothesis of extracellular accumulation, secondary to prolonged hyperglycemia in IDDM, production of alternated non-enzymatic glycosylated end products with neoantigen formation, B cell predominant inflammation with autoimmune response against neoantigens and cytokine release secondary to the autoimmune response.

Diabetic mastopathy, an uncommon form of lymphocytic mastitis and stromal fibrosis, typically occurs in longstanding type 1 diabetes. Nineteen cases meeting predetermined histopathologic criteria for diabetic mastopathy were correlated as to clinical history and disease recurrence. Physical examination revealed palpable discrete masses or diffuse nodularity, both predominantly in the subareolar region. One nonpalpable lesion was detected incidentally during reduction mammoplasty. All cases contained lymphocytic ductitis and lobulitis with varying degrees of keloidal fibrosis, vasculitis, epithelioid fibroblasts, and lymphoid nodule formation. Single mammary lesions were found in 11 patients with type 1 diabetes, 1 with type 2 diabetes, and 3 without diabetes. Four cases were bilateral (3 patients with type 1 and 1 patient with type 2 diabetes). Six of 19 cases recurred (3 ipsilateral, 2 contralateral, and 1 bilateral). We confirm the histopathologic constellation for diabetic mastopathy. However, we question the specificity of these features because of identical findings in patients with type 2 diabetes and nondiabetic patients. We found diabetic mastopathy in men and women, as a solitary mass or bilateral disease, and recurrence in either breast, sometimes multiple. Recognition of potential recurrence is important because it might spare patients with documented diabetic mastopathy from repeated breast biopsies.

Diabetic mastopathy, although reported since 1984, is a poorly recognized diabetes complication. It more frequently affects pre-menopausal women with Type 1 diabetes mellitus and microvascular complications. The pathogenesis of this condition is believed to involve mammary tissue autoimmune reaction to the accumulation of abnormal matrix proteins, caused by hyperglycemia. The lesion often simulates breast cancer; its recognition, therefore, is important to avoid unnecessary diagnostic procedures and surgical treatments. We now report a case of diabetic mastopathy which clinically simulated breast cancer in a young pre-menopausal diabetic woman who, after sonography and mammography, was suggested surgery under suspicion of breast cancer. Histopathological examination by core-biopsy ruled out malignancy.

Diabetic mastopathy, or diabetic fibrous breast disease is a well-characterised benign, fibro-inflammatory condition affecting women with insulin dependent diabetes. To date the relationship between this condition and breast carcinoma has been poorly reported. We describe a case of breast carcinoma arising within a diabetic fibrous breast lesion, in a renal transplant recipient.

Diabetic mastopathy is an uncommon tumor-like proliferation of fibrous tissue of the breast that usually occurs in a patient who has suffered from type I diabetes mellitus of long duration. Here we report a rare case of diabetic mastopathy that occurred in type II non-insulin dependent diabetes mellitus. This patient was a 63-year-old postmenopausal woman. Mammography, ultrasonography and MR imaging could not distinguish it from breast cancer. Although the core needle biopsy specimen showed fibrosis without evidence of malignancy, excisional biopsy was performed. Histological findings demonstrated typical diabetic mastopathy with keloid-like fibrosis, perivascular lymphocytic infiltration, and lymphocytic lobulitis without evidence of malignancy. These lymphocytes were composed predominantly of B-cells. Five months after surgical biopsy, a nodular formation approximately 4 cm in diameter recurred adjacent to the resected end of the biopsy.

Diabetic mastopathy is a clinicopathologic entity that represents less than 1% of benign breast disease and is mainly related to type 1 diabetes. The pathogenesis is unknown but the most convincing hypothesis postulates extracellular collagen deposit and predominantly B-cell inflammation with autoimmune response. The clinical, radiological and pathological features of four patients with diabetic mastopathy are presented.

Diabetic mastopathy is an uncommon disorder of the breast seen mostly in young women suffering from type 1 diabetes mellitus. The presenting symptom is a rapidly growing breast lump that may simulate breast cancer. Clinically and radiologically it can be indistinguishable from breast carcinoma. Recognizing this clinical entity, in addition to close collaboration between the clinician and the pathologist can facilitate its early diagnosis, avoiding unnecessary alarm for the patient. A 36 years old patient with a long-standing type 1 diabetes mellitus was admitted to surgery for a rapidly growing left breast lump. Excisional biopsy of the lump revealed diabetic mastopathy.

We report a case of diabetic mastopathy in an elderly woman with type 2 diabetes. The patient was a 69-year-old woman diagnosed with type 2 diabetes at the age of 33 years. She had been treated with insulin for 25 years, however, her blood glucose had been poorly controlled. She noticed bilateral breast lumps in September 2002. Mammography of the breast showed increased density in the glandular pattern and architectural distortion without focal mass and microcalcification. Ultrasonography of the breast showed an irregular-shaped hypoechoic mass with an acoustic shadow. As malignancy needed to be excluded, core needle biopsy was performed in the left breast and diabetic mastopathy was confirmed pathologically. Diabetic mastopathy is usually a complication of pre-menopausal type 1 diabetes and develops in a unilateral breast. This case developed in bilateral breasts in an elderly type 2 diabetic patient.

We report a case of diabetic mastopathy in a man with type 2 diabetes. The patient was a 62-year-old man who had been diagnosed with type 2 diabetes at the age of 46 years. He had been treated with oral hypoglycemic agents. He noticed a mass in his left breast in February 2007, when HbA(1)c was 7.6% with the treatment using oral hypoglycemic agents, including acarbose, glimepiride, buformine, and pioglitazone. Mammography of the breast showed increased density, and ultrasonography showed a regular-shaped hypoechoic mass. Core needle biopsy was performed, and diabetic mastopathy was confirmed pathologically. Diabetic mastopathy usually occurs in women with type 1 diabetes. This case, a man with type 2 diabetes, is very rare.

Diabetic mastopathy is an uncommon benign entity occurring in young women with type 1 diabetes. Its clinical and radiological signs are not specific and often mimic a breast carcinoma. However, the benign nature of this lesion is easily recognized on histological examination, visualizing dense keloid-like fibrosis, lymphocytic lobulitis and ductitis with lymphocytic perivascular inflammation, with or without epithelioid-like fibroblasts. Surgery can generally be avoided. The evolution of this entity is characterized by the risk of local growth, bilateralisation or recurrence after surgical treatment. We present a case in which the core biopsy allowed the diagnosis of a diabetic mastopathy and we discuss its clinical, diagnostic, pathological and therapeutic particularities.
