AN INTERESTING CASE OF INGUINAL NODAL METASTATIC MELANOMA OF UNKNOWN PRIMARY

INTRODUCTION - Melanoma with unknown primary (MUP) accounts for approximately 1 to 8 percent of all melanomas and was described first in 1952. CASE STUDY - 60 years old male patient presented with swelling over left upper thigh for 3 months duration. With past history of excisional biopsy of nearby swelling showing secondary deposit possibly from Sertoli cell Tumour of Testis or Rhabdomyosarcoma. The patient was treated with Ilioinguinal Block dissection, and the Histopathological report revealed metastatic deposit of malignant melanoma, without clinical or radiological evidence of a known primary. CONCLUSION - The importance of presenting this paper is to highlight the rare presentation of malignant melanoma metastatic to inguinal lymph nodes from an unknown primary, and the need to aggressively treat these patients as they have a better prognosis than those with a known primary .
