摘要
A 58-year-old woman complicated with autoimmune diseases of myasthenia gravis (MG), rheumatoid arthritis, and systemic lupus erythematosus noticed an irregular black macule on her bilateral major labia, which was diagnosed as malignant melanoma. The melanoma lesion involving the vagina, uterus, and ventral side of rectum was not operable and was treated with nivolumab and concurrent radiotherapy with good control of the MG. This resulted in remarkable tumor shrinkage, possibly due to synergistic effects of both treatments. To our knowledge, few reports have described the effectiveness of combination therapy with nivolumab and radiation for malignant melanoma. The present case showed an enhanced anti-tumor effect with combination therapy.
