RESUMEN
O nevo de Spitz pigmentado consiste em uma lesão melanocítica benigna com características peculiares. Geralmente, melanoma é considerado no diagnóstico diferencial desta lesão, bem como o nevo de Reed. A dermatoscopia representa uma parte relevante da abordagem diagnóstica e, portanto, ela permite um estudo mais eficiente dessas lesões dermatológicas. O presente relato de caso é sobre uma paciente com dois nevos de Spitz pigmentados de localização no tronco e história familial de melanoma, no qual a dermatoscopia associada à histopatologia foram cruciais para o diagnósticos das lesões.

Pigmented Spitz nevus is a benign melanocytic skin lesion with distinct clinical features and it is frequently found on the extremities. However, it rarely occurs on acral area of the body, and such a case has not yet been fully documented. We present a case of acral pigmented Spitz nevus occurring on the foot, and this mimicked acral lentiginous malignant melanoma. Clinicians should be well aware of this entity and its possible clinical presentations. Since acral pigmented Spitz nevus is benign in nature, making the correct diagnosis is important to avoid unnecessary mutilating or excessive surgery.

Clinically, Spitz nevi usually appear as asymptomatic, dome-shaped, round to oval, firm nodules with a wide spectrum of colors ranging from translucent to purple, brown or black. The degree of pigmentation varies with the age of the patient and more darkly pigmented lesions are rare in children. Herein, we report an unusual case of pigmented Spitz nevus in a 7-year-old boy, which clinically resembles malignant melanoma.
