Paget's disease of the nipple diagnosed on cytology: a case report.

Paget's disease of the breast nipple is an eczematous skin change of the nipple-areola complex often associated with an underlying in-situ or invasive carcinoma. The usefulness of cytology in the diagnosis of Paget's disease has been suggested only in few studies despite the fact that it offers definitive advantages over surgical excision biopsy. Easy practicability, quick, cost-effective and non-invasive stands opposite a limited sensitivity as disadvantage. We report a case of Paget's disease of nipple diagnosed by nipple touch smears.
