Malignant melanoma is one of the most common malignant tumors. Although its incidence rate is generally low among the Chinese population, it has grown rapidly in recent years. The incidence of primary malignant melanoma in the digestive tract is very low. The incidence in the esophagus and rectum are more common, while reports in the colon are only reported in <10 cases. Primary signet ring cell carcinoma of the rectum is also a rare and unique tumor. This paper reports a case of rectal malignant melanoma with signet ring cell carcinoma.
恶性黑色素瘤是最常见的恶性肿瘤之一。虽然其发病率在中国人群中总体较低，但近年来呈快速增长趋势。消化道原发性恶性黑色素瘤的发病率非常低。在食管和直肠的发病率较为常见，而结肠的报道仅有不到10例。直肠原发性印戒细胞癌也是一种罕见且独特的肿瘤。本文报道1例直肠恶性黑色素瘤伴印戒细胞癌的病例。
