ABSTRACT
A giant congenital melanocytic nevus represents a rare condition. The halo phenomenon may be seen in congenital or acquired melanocytic nevi. In the literature, association of halo nevus and giant congenital melanocytic nevus is rare and the association of both with vitiligo even more rare. A 75-yearold woman at first consultation complained of a hyperchromic bluish-brown hairy macula on the lower back, buttocks and thighs present since birth and an achromic halo of onset three years ago. The histological features were consistent with congenital melanocytic nevus and halo nevus, respectively. After two years the patient developed achromic areas in normal skin, histologically consistent with vitiligo. The authors emphasize the rarity of this triple combination, the patient's age and the absence of malignant degeneration to date.
RESUMO
Nevo melanocitico congênito gigante constitui uma condição rara. O fenômeno halo pode ser observado em nevos melanocíticos congênitos ou adquiridos. Na literatura a associação nevo halo e nevo melanocítico congênito gigante é rara e a associação de ambos com vitiligo ainda mais rara. Mulher de 75 anos que à primeira consulta apresentava mácula hipercrômica castanho-azulada pilosa na região lombar, nádegas e coxas desde o nascimento e halo acrômico de aparecimento há 3 anos. Os histológicos foram compatíveis com nevo melanocítico congênito e nevo halo respectivamente. Após dois anos evoluiu com áreas de acromia à distância, com histológico de vitiligo. Os autores ressaltam a raridade desta tripla associação; a idade da paciente e a ausência de degeneração maligna até o presente momento.
