[Mastitis-like changes as debut symptom of Kaposi's sarcoma and AIDS].

Kaposi's sarcoma of the breast is rare but has been reported to imitate breast lumps or gynaecomastia, usually accompanied by Kaposi's sarcoma of the skin. We report a case of a patient presenting with mastitis of the breast as the first symptom of Kaposi's sarcoma and AIDS. Although uncommon, the diagnosis should be considered in patients with mastitis without other obvious causes.
