Blue nevi are small acquired melanocytic tumors. Two clinical forms are described, a fibrous form and a cellular form. Giant nevi are exceptional.
We describe a patient with a giant blue nevus of the scalp. In addition to this congenital, noninvasive tumor the patient presented numerous cutaneous melanocytic nevi. The main lesion was removed by surgical exeresis followed later with reconstruction plasty. The histological examination of the surgical specimen showed an infiltrating blue cell nevi. After a 4-year follow-up, there has been no recurrence and no metastasis.
There have been 11 cases of giant blue nevi reported in the literature. All were congenital lesions with polymorphous clinical and histological aspects. Fibrous forms are noninvasive and cellular forms have a potential for local invasion, whether shortly after birth or later with invasion of muscles, bone and meninges without intracerebral extension. Congenital blue nevi require early surgical exeresis.
蓝色痣是一种后天获得性小黑素细胞肿瘤。描述了两种临床类型，一种是纤维型，另一种是细胞型。巨大痣极为罕见。
我们描述了一名患有头皮巨大蓝色痣的患者。除了这种先天性非侵袭性肿瘤外，该患者还存在许多皮肤黑素细胞痣。主要病变通过手术切除，随后进行重建整形手术。手术标本的组织学检查显示为浸润性蓝色细胞痣。经过4年的随访，未出现复发和转移。
文献中报道了11例巨大蓝色痣病例。所有病例均为先天性病变，具有多形性的临床和组织学表现。纤维型为非侵袭性，细胞型有局部侵袭的可能，无论是在出生后不久还是后期侵袭肌肉、骨骼和脑膜而无脑内扩展。先天性蓝色痣需要早期手术切除。
