Cytological diagnosis of collagenous spherulosis of breast associated with fibroadenoma: report of a case with review of literature

Abstract

Collagenous spherulosis of the breast is a rare incidental finding frequently associated with other benign lesions of the breast. The estimated incidence of this innocuous condition is only about 0.2% in cytological material. It is of utmost importance to differentiate collagenous spherulosis from its malignant mimics to avoid unnecessary treatment. This article discusses the cytological findings of a case of collagenous spherulosis of breast associated with fibroadenoma, along with a brief review of literature.
