BACKGROUNDFine needle aspiration cytology is known to have a well-established role in the diagnosis and management of palpable breast lumps. Breast carcinoma is the second most common cause of death in female patients, male breast carcinoma is rare, accounting for less than 1% of all breast cancers and all cancers in men. Male breast masses are rarely aspirated and hence there is limited cytopathological experience.The aim of our study is to determine the efficacy of FNAC in the diagnosis of male breast lesions.

Aqueous Medium. -Tertiary amines catalyze the ring expansion of aziridines (I) to 2-aroyl-azetidines (III) with nitrogen ylides formed in situ from phenacyl bromide derivatives (II). The reaction proceeds with high cis-diastereoselectivity. -(GARIMA; SRIVASTAVA, V. P.; YADAV*, L. D. S.; Green Chem. 12 (2010) 8, 1460-1465, http://dx.doi.org/10.1039/c004736h ; Lab.
