Recurrent Melanoma Inguinal Lymph Node as unknown Primary Disease: A Case Report

Abstract

A-63-year old male presented with left inguinal swelling. Swelling was non-tender and firm in consistency. It measured 5×3×1 cm. Fine needle aspiration cytology was done. Smears were stained by H&E and Papanicolaou staining methods. Smears were hypercellular and showed plasmacytoid cells. Nucleomegaly and anisonucleosis were seen. Clumped chromatin with single conspicuous nucleolus was also seen. The patient had a recurrent lesion and cytological atypia. Cytological findings suggested the tumour to be a malignant melanoma. Keywords: Malignant tumour, Groin swelling, Cytoplasmic melanin pigment granules.
