Neurofibroma of breast- A rare case report

Neurofibroma are benign tumour of peripheral nerve sheath that are mostly sporadic. Solitary neurofibromas of breast are uncommon. In this study, a case of 21-year-old female was referred with complaint of hyper pigmented lump in left breast since birth with recent increase in size for 5 months. Ultrasonography revealed a well-defined hypoechoic Space occupying lesion in subcutaneous plane at 11’o clock position of left breast along with a large ill-defined hypoechoic area with normal vascularity noted extending from 11’o clock to 2’o clock areas in left breast. Microscopically, the underlying stroma showed proliferating spindle cells with interspersed collagen bundles. Spindle cells show bland serpentine (wavy dark) nuclei and scant cytoplasm.
