The diagnosis of pediatric atypical Spitz nevus/tumors (pASNT) is an emerging challenge in clinical dermatology and dermatopathology.
We review the main clinicopathologic issues raised by pASNT and describe 2 examples of different clinicopathologic subsets of lesions.
While Spitz/Reed nevi are commonly small- to medium-sized, tan to black plaques, pASNT are large and nodular, either 'red' (dotted and/or polymorphous vascular pattern on dermoscopy; spindle and/or epithelioid tumors on histopathology: Spitz tumors, sensu strictiori) or 'blue' (homogeneous blue color on dermoscopy; intimate admixture of epithelioid cells and heavily pigmented dendritic cells on histopathology: Blitz tumors or pigmented epithelioid melanocytomas).
Different clinicopathologic settings of pASNT probably exist. Dermoscopy can aid in their recognition and classification.
儿科非典型 Spitz 痣/肿瘤(pASNT)的诊断是临床皮肤科和皮肤病理学领域面临的新挑战。
我们回顾了 pASNT 提出的主要临床病理问题,并描述了两种不同临床病理亚组病变的实例。
Spitz/Reed 痣通常为小至中等大小,呈棕黑色斑块,而 pASNT 则较大且呈结节状,呈“红色”(皮损镜检呈点状和/或多形性血管模式;组织病理学呈梭形和/或上皮样肿瘤:严格意义上的 Spitz 肿瘤)或“蓝色”(皮损镜检呈均匀蓝色;组织病理学呈上皮样细胞和重度色素性树突状细胞混合:Blitz 肿瘤或色素性上皮样黑素细胞瘤)。
pASNT 可能存在不同的临床病理表现。皮损镜检有助于识别和分类。
