A 96-year-old man presented with a polypoid melanoma, which showed a prominent clear stroma, similar to that of myxoid melanoma, but stained negative for Alcian blue at pH 2.5 and for colloidal iron. It is not clear whether melanoma displaying pseudomyxoid features (pseudomyxoid melanoma) may represent a distinct histological variant of melanoma. However, it must be differentiated from true myxoid melanomas, in which Alcian blue-positive acid mucopolysaccharides are present. Urso C. Cutaneous melanoma with pseudomyxoid features.
一名96岁男性患有息肉状黑色素瘤，其显示出明显的透明间质，类似于黏液样黑色素瘤，但在pH 2.5时阿尔辛蓝染色阴性且胶体铁染色阴性。目前尚不清楚表现出假黏液样特征的黑色素瘤（假黏液样黑色素瘤）是否可能代表黑色素瘤的一种独特组织学变体。然而，它必须与真正的黏液样黑色素瘤相鉴别，真正的黏液样黑色素瘤中存在阿尔辛蓝阳性酸性黏多糖。乌尔索C。具有假黏液样特征的皮肤黑色素瘤。
