RESUMO
La melanosis pustulosa transitoria neonatal(MPTN)es un desorden pustularno infeccioso raro, de carácter benigno y autolimitado, más frecuente en la raza negra.Se caracteriza por la presencia de pústulas prominentes sin base eritematosa, que luego de su rupturadejan un collarete descamativo y posteriormente hiperpigmentación residual que puede durar varios meses. Compromete principalmente la cabeza, el cuello, el tronco y lasextremidades inferiores.Los hallazgos histopatológicos consisten en la presencia de neutrófilos formando pústulas estériles subcórneas. No existe afección sistémica y no requiere tratamiento. Se presenta el caso de un paciente varón de 10 días de vida, con múltiples máculas hiperpigmentadas en el tronco y las extremidades inferiores desde el nacimiento.
Transient neonatal pustularmelanosis is a rare benign and self-limited non-infectious pustular disorder, more common in blacks. It is characterized by the presence of prominent pustules without erythema, that leave a scaly collaretteafter rupture and residual hyperpigmentation that may last several months. It mainly affects thehead, neck, trunk and lower extremities. Histopathologicalfindings are the presence of neutrophils forming subcorneal sterile pustules. There is no systemic involvement and it does not require treatment.We report a 10-days old male patient with multiple hyperpigmented macules on the trunk and lower extremities since birth.

Transient neonatal pustular melanosis(TNPM) is a benign, self-limited, cutaneous disorder of unknown etiology. Significant physical findings are limited to the skin. Hematologic and serological tests are normal. Cultures of blood and pustule are negative. Biopsy specimens from pustules show a intracorneal or subcorneal separation containing neutrophils and also some eosinophils. TNPM produces only cutaneous lesions and requires no treatment. So it is essential to differentiate TNPM and other neonatal skin lesions. We experienced a case of TNPM in a male newborn with generalized superficial vesicopustules which developed into pigmented macules and report this case with review of related literatures.

A 6-day-old female infant had generalized superficial pustules which evolved into pigmented maucles, many of which had a peripheral collarvtte of scale. Histopsthologic stadies showed intracormeal aggregates of neutrophils. The appearance of the lesions and histopathologic finding fitted transient neonal pustular melanosis.
