Chronic Mastitis

Breast carcinoma occurring from chronic granulomatous mastitis.

Chronic granulomatous mastitis is known as a benign and relatively rare disorder that is often difficult to differentiate from breast carcinoma. We highlight the case of a 34-year-old woman who had recurrent episodes of right breast swelling and abscess for 8 years. These were proven to be chronic granulomatous mastitis by tissue biopsies on 3 different occasions. Her condition improved on simi...

The problem of 'chronic mastitis' with epitheliosis.

The incidence of breast cancer complicating chronic mastitis with epitheliosis has been reported to be as high as 45% and as low as 6%. At least part of this discrepancy appears to be due to difficulty in distinguishing between benign and malignant intraduct epithelial proliferation.A small series is presented here in which the incidence of invasive cancer after local excision of breast tissue ...

[Idiopathic chronic granulomatous mastitis: a case report].

Idiopathic chronic granulomatous mastitis is a rare disease in women at the reproductive life with clinic, mammographic, echographic and cytological characteristics suggestive of breast cancer. We report a case of breast pathology in a 35 years old woman who had a sensitiveness and eritematous tumor localized in the left breast. With the diagnosis of "mastitis", she was treated with antibiotics...

Capsule-negative Staphylococcus aureus induces chronic experimental mastitis in mice.

Staphylococcus aureus capsular polysaccharides (CP) have been shown to enhance staphylococcal virulence in numerous animal models of infection. Although serotype 5 CP (CP5) and CP8 predominate among S. aureus isolates from humans, most staphylococcal isolates from bovines with mastitis in Argentina are capsule negative. This study was designed to evaluate the effects of CP5 and CP8 expression o...
