We report a case of primary malignant melanoma (MM) of the female urethra. A 60-year-old female complained bleeding from the urethral meatus. MRI revealed a mass of 20 mm at the external urethral meatus. Pathological examination of transurethrally resected specimens revealed MM with stromal invasion. She underwent total urethrectomy plus cystostomy and sentinel lymph node biopsy. The tumor was pathologically confined in the specimen and no lymph node metastasis was found. She received interferone β as adjuvant therapy. However, she developed bilateral adrenal and pulmonary hilar lymph node metastases 1 year after urethrectomy. Although she started to receive nivolumab as salvage therapy, the disease progressed as well as development of interstitial pneumonia (IP) after four cycles. Following improvement of IP with steroid therapy, she started to receive ipilimumab, which resulted in the development of intolerable IP of grade 3. The patient finally died of MM 19 months after the initiation of treatment.

D008207 Lymphatic Metastasis Transfer of a neoplasm from its primary site to lymph nodes or to distant parts of the body by way of the lymphatic system. Lymph Node Metastasis,Lymph Node Metastases,Lymphatic Metastases,Metastasis, Lymph Node
D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D004724 Endoscopy Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.

D000074324 Ipilimumab An anti-CTLA-4 ANTIGEN monoclonal antibody initially indicated for the treatment of certain types of metastatic MELANOMA. Its mode of actions may include blocking of CTLA-4 mediated inhibition of CYTOTOXIC T LYMPHOCYTES, allowing for more efficient destruction of target tumor cells.

D000077594 Nivolumab A genetically engineered, fully humanized immunoglobulin G4 monoclonal antibody that binds to the PD-1 RECEPTOR, activating an immune response to tumor cells. It is used as monotherapy or in combination with IPILIMUMAB for the treatment of advanced malignant MELANOMA. It is also used in the treatment of advanced or recurring NON-SMALL CELL LUNG CANCER; RENAL CELL CARCINOMA; and HODGKIN'S LYMPHOMA.
