Breast Adenomyoepithelioma with predominance of morules: a cytological dilemma.

Abstract

Adenomyoepithelioma is a rare, benign proliferative tumour that can involve the breast. It is usually present as a solitary, unilateral, painless mass at the periphery of the breast in women range in age from 26 to 82 years (average 63 years). Tumour sizes range from 0.5 to 8 cm.(average size 2.5 cm).We report a case of adenomyoepithelioma of right breast in a 58 years old female since two months with diagnostic difficulty on cytology, especially with morules predominance that merits documentation due to its rarity.On physical examination, it was a single well defined, lobulated, non mobile, firm mass of 10 x 8 x 5 cm in upper outer quadrant of right breast without associated axillary lymphadenopathy. Sonomammography showed well defined lobulated right breast mass with macrolobulations and cystic changes suggestive of phyllodes tumour. Wide local excision was performed and histopathological study revealed adenomyoepithelioma which is confirmed by P63 immunostain.
