Plexiform epithelioid schwannoma: a case report.

Epithelioid schwannoma is rare but may pose a challenge in histopathologic diagnosis. In the present report, we describe a plexiform variant of epithelioid schwannoma in the skin of the breast of a 47-year-old woman.

Role of primary breast cancer characteristics in predicting positive sentinel lymph node biopsy results: a multivariate analysis.

Hypothesis: Certain primary breast tumor characteristics can be used to predict positive sentinel lymph node biopsy (SLNB) results and thus determine which patients should undergo SLNB.

Design: Retrospective review of patients undergoing SLNB for invasive breast cancer from March 1, 1998, through March 31, 2001.

Setting: University-affiliated tertiary care hospital.
