Aim: The present study demonstrates the recent experiences in histopathological diagnosis of phyllodes tumor of breast. Material & Methods: Histopathological slides and medical records of eleven cases of phyllodes tumor of breast diagnosed at the Department of Pathology, SRMSIMS, Bareilly from January 2013 to December 2016 were reviewed. Cases were evaluated for degree of stromal cellularity and atypia, mitotic count, stromal overgrowth, and the nature of the tumour borders. Results: The median age at diagnosis was 45 years (range 30 years to 58 years). Mean tumor size was 10.2 cm (range 22cm to 6cm). Tumors predominated on the right side (54.5%). Wide tumorectomy was performed in seven patients and four patients underwent mastectomy. FNAC was performed in seven cases out of which 3 cases were diagnosed as phyllodes, 2 cases showed possibility of phyllodes and 2 cases were diagnosed as fibroadenomas. Histopathologically 10 cases were diagnosed as benign phyllodes and one case was diagnosed as borderline or low malignant potential. There were two cases of recurrent benign phyllodes tumor. Conclusions: The confrontation of our results to the data of the medical literature shows that histological confirmation is required for the diagnosis of phyllode tumors. The treatment of choice is surgery. The prognosis depends on the histological characteristics of these tumors.
