title: Breast abscess as the initial presentation of squamous cell carcinoma of the breast.
abstract: Breast abscesses are common and rarely harbour an underlying malignancy. Antibiotics and drainage by aspiration are the mainstays of treatment. We encountered two post-menopausal patients aged 48 and 70 who presented with acute breast abscesses that had an underlying squamous cell carcinoma of the breast. Infective aetiology was considered in each case and pre-operative diagnosis is possible but requires a high level of suspicion to avoid a delay in diagnosis. Aspirate from the abscess should be sent for both culture and cytology and if drainage is done, then biopsy of the abscess cavity is essential. Clinicians should be aware of the association of this rare primary neoplasm of the breast.
