The solitary cutaneous mastocytoma is a variant of cutaneous mastocytosis which carries a good prognosis. It may develop at a very early age, during the first weeks of life, or even be congenital. Typically, they present as red-brownish lesions that may be asymptomatic or present systemic manifestations associated with histamine release.
A 19-year-old female patient who attended a medical consultation for a pigmented lesion, slightly raised in the left antecubital fold, asymptomatic, of recent appearance and progressive growth. Dermoscopy reported a fine symmetrical network, yellowish-brown in color and randomly distributed black dots. The pathology report and immunohistochemical findings were consistent with mast cell tumor.
The solitary cutaneous mastocytoma should not be considered as an exclusive entity in the pediatric population. Acknowledgment of its atypical clinical presentation with its dermatoscopic features, is useful for diagnosis.
孤立性皮肤肥大细胞瘤是皮肤肥大细胞增多症的一种变体，预后良好。它可能在很早的年龄，即出生后的头几周就出现，甚至可能是先天性的。典型情况下，它们表现为红棕色病变，可能无症状，或出现与组胺释放相关的全身表现。
一名19岁女性患者因左侧肘前窝出现一个色素沉着病变前来就诊，该病变略有隆起，无症状，近期出现且呈进行性生长。皮肤镜检查报告显示有一个精细对称的网络，呈黄棕色，并有随机分布的黑点。病理报告和免疫组化结果与肥大细胞瘤一致。
孤立性皮肤肥大细胞瘤不应被视为仅见于儿科人群的疾病。认识到其具有皮肤镜特征的非典型临床表现，有助于诊断。
