A rare case of primary malignant melanoma of cervix with metastasis to inguinal lymph node detected on 18F-FDG PET-CT scan

Primary malignant melanoma of uterine cervix is extremely rare malignancy with very few case published reports. This neoplasm is having poor prognosis, so early diagnosis, staging and treatment is of extreme importance. 18F-FDG PET-CT (18F-labeled fluoro-2-deoxyglucose positron emission computed tomography) scan is an established modality to determine exact extent of disease in malignant melanoma thus determining the treatment protocol. In this reported case, PET-CT is showing primary lesion in uterine cervix with extension in to the vagina and involvement of left inguinal lymph nodes. No other abnormal 18F-FDG avid lesion or distant metastases noted in the scanned region of the body.
