转移性黑色素瘤与低分化腺癌的鉴别诊断有时仍是困难的。作者报告2例以往没有描述过的黑色素瘤形态学类型。常规HE切片瘤细胞呈明显的印戒状,貌以转移性印戒细胞癌,作者将其命为印戒细胞黑色素瘤。例1为35岁男性,平素健康,右腋下一肿块,表面皮肤无病变,行肿块切除,最初诊断为转移性腺癌,临床检查无特殊。例2为63岁女性,有皮肤黑色素瘤病史,做腹股沟淋巴结切除,肿瘤已累及多个淋巴结。
The differential diagnosis of metastatic melanoma and poorly differentiated adenocarcinoma is sometimes still difficult. The authors report two types of melanoma morphologies that have not been described previously. The conventional HE slice tumor cells showed a marked signet ring appearance, metastasis signet ring cell carcinoma, the author will be the signet ring cell melanoma. Example 1 was a 35-year-old man with normal health, an inferior mass on the right side of the eye, no skin lesions on the surface, and a lumpectomy. The initial diagnosis was metastatic adenocarcinoma. There was no clinical examination. Case 2 is a 63-year-old woman with a history of skin melanoma. Her inguinal lymph node resection was performed and the tumor had involved multiple lymph nodes.
