Fibromatosis is a fibroblastic lesion composed of uniform fibroblasts and collagen with an infiltrative growth pattern but lacking malignant cytological features. It is a rare entity and is even more unusual when found in the breast. Multicentricity in fibromatosis has been reported in 10% cases. Multicentricity in breast cancer has been defined as the presence of two or more tumor foci within different quadrants of the same breast. Considering this definition of multicentricity for fibromatosis, we herein report a case of recurrent multicentric aggressive mammary fibromatosis and its cytological features with review of literature because of limited literature of (FNAC) in mammary fibromatosis.
