在黑人及日本人中,跖部是黑素瘤最好发的部位,而白人此处的黑素细胞肿瘤(良性及恶性)却十分罕见。为了了解白人跖部黑素细胞性肿瘤的临床诊断标准及制定治疗办法,对148例具有跖部色素性损害的白人患者进行回顾性研究。这些患者最初的临床诊断包括:黑素细胞痣,可疑黑素瘤、皮肤黑素瘤(CM)和其它。所有切除的标本均做了病理检查。结果:临床诊断为痣的170例中,仅2例病理检查不能证实为痣,但无一例为 CM。临床疑为 CM 的10例中,6例病理显示为
In blacks and Japanese, the melanoma is the best site for melanoma, and melanoma tumors (benign and malignant) are rare in whites. In order to understand the clinical diagnostic criteria of white melanotic melanocyte tumors and to develop therapeutic approaches, a retrospective study was performed on 148 white patients with pigmented vermis. The initial clinical diagnosis of these patients included melanocytes, suspected melanoma, cutaneous melanoma (CM), and others. All excised specimens were pathologically examined. RESULTS: Among the 170 cases of clinically diagnosed spasticity, only 2 cases were not confirmed as sputum by pathological examination, but none of them were CM. Among the 10 cases with clinically suspected CM, 6 cases showed pathological
