title: Spontaneous infarction of an intraductal papilloma of the breast: cytological presentation on fine needle aspiration.
abstract: A relatively rare case of spontaneous infarction of an intraductal papilloma of the breast is presented which was considered to be suspicious for malignancy on fine needle aspiration (FNA) cytology. The aspirate revealed several groups of atypical cells featuring a high nuclear-cytoplasmic ratio, coarsely granular chromatin, and somewhat prominent nucleoli. There was abundant necrotic cellular debris in the background. These cellular features were considered evidence of ductal carcinoma of the breast. The correct diagnosis was made by open biopsy which revealed necrosis involving the breast due to infarction of an intraductal papilloma.
