El hamartoma o nevus oligemicus es una entidad infrecuente, de etiopatogenia poco aclarada, en la que se produce una vasoconstricción selectiva del plexo vascular profundo dérmico con relación al superficial. Estas alteraciones funcionales dan lugar a lesiones fijas, adquiridas y asintomáticas a modo de máculas lívidas, eritematosas, típicamente frías al tacto si se compara con la piel sana adyacente. Comunicamos los casos de 6 varones jóvenes con lesiones en el abdomen y en los flancos, compatibles clínicamente con nevus oligemicus. La medición de la temperatura superficial de la lesión, constatando un descenso de hasta 2,5 °C respecto de la piel sana adyacente, permitió realizar el diagnóstico definitivo. Se describen los estudios complementarios realizados, los diagnósticos diferenciales, los posibles agentes etiológicos responsables y se comentan los casos referidos en la literatura hasta el momento. Consideramos que el nevus oligemicus es una entidad infradiagnosticada y mucho más frecuente de lo referido en la literatura (AU)
Hamartoma or nevus oligemicus is an uncommon lesion that is characterized by selective vasoconstriction of the deep dermal vascular plexus with respect to the superficial one and whose cause has not been clearly established. This selective vasoconstriction gives rise to fixed, acquired, and asymptomatic lesions in the form of livid, erythematous macules that are typically cold to touch compared with surrounding skin. We report the cases of 6 young men with lesions clinically compatible with nevus oligemicus on the abdomen and flanks. Measurement of the surface temperature of the lesion revealed a decrease of up to 2.5 °C with respect to healthy surrounding skin and allowed a definitive diagnosis to be made. We describe the additional studies undertaken, the differential diagnosis, and the possible etiologic agents, and discuss the cases reported in the literature to date. In our opinion, nevus oligemicus is an underdiagnosed lesion that is much more common than has been reported in the literature (AU)

Presentamos un caso de mastocitoma solitario localizado en piel escrotal en un niño de 5 años. El único síntoma referido era prurito moderado. El signo de Darier fue provocado rascando la lesión. Histológicamente, se constató infiltrado mastocitario en la dermis, lo que confirmó el diagnóstico. La localización de esta lesión en región genital es inusual (AU)

We report the case of solitary mastocytoma, which appeared under the identification bracelet on the left wrist of a 2-day-old newborn infant. Stroking the lesion elicited Darier's sign. Histopathologic examination of a punch biopsy specimen revealed a dense mast cell infiltrate of the dermis, which was confirmed by Giemsa and toluidine blue stains. We believe that this case represents and unusual reactive process.
