以下是引用mingfuyu在2008-8-5 8:00:00的发言:
Spindle cell malignancy. I wish i could see more epidermis and dermal-epidermal junction. Last 2 photos appear to have in-situ melanoma but not sure. If you don't have immunostain, to establish melanoma in situ is critical in coming to the right diagnosis. If you can tell for sure those pigments are melanin, that would be diagnostic too. Unfortunately i favor melanin but cannot be sure from the photos. |
译文:梭形细胞恶性肿瘤。我希望能看到较多的表皮和真皮表皮交界处。最后2张图片似乎有原位黑色素瘤但不能肯定。如果你没有做免疫标记,看到原位黑色素瘤对正确诊断非常重要。如果你能确信这些色素是黑色素,那么也可以做出诊断。然而,我不能从这些图片中确信是黑色素。
