FNB diagnosis of breast carcinoma associated with HIV infection: a case report and review of HIV associated malignancy.

A 48 yr old HIV seropositive female presented with a right breast mass and bilateral axillary lymphadenopathy. Fine needle biopsy (FNB) revealed an adenocarcinoma with abundant mucin production and features suggestive of a cribriform and micropapillary ductal carcinoma in situ (DCIS). Histopathological examination of the tumor confirmed an invasive mixed colloid carcinoma with extensive DCIS. There have been 4 previous reports in the literature of breast carcinoma associated with HIV seropositivity. This case initially diagnosed by FNB is the first case reported in Australia. In spite of the somewhat more favourable histological type of breast carcinoma, this tumor shows numerous unfavourable prognostic factors and has had an aggressive clinical course with relapse of disease in the contralateral breast and distant metastases within 4 wks of surgery, probably related to the patient's immunodeficiency.
