Fig. 3). For a histological diagnosis, he underwent USS guided fine needle aspiration, the histology revealed appearance of low grade lesion with no evidence of malignancy and diffuse cytokeratin positivity, majority of cells being S100 negative- making PNST (Peripheral Nerve Sheath Tumour) unlikely and
Lesion noted in situ prior to excision.
