ReferencesPrurigo pigmentosa é unha rara condición inflamatoria da pel descrita por primeira vez por Nagashima et al. en 1971. Afecta principalmente a mulleres novas de orixe asiática, pero tamén pode ocorrer noutras. Aparece como unha erupción simétrica de protuberancias vermellas elevadas no pescozo, no peito e nas costas. Estes brotes adoitan formar un patrón de rede e poden ir e vir, deixando manchas máis escuras na pel. O prurigo pigmentosa pode ser provocado por cambios no metabolismo, como os causados polas dietas cetoxénicas, que se fixeron máis populares recentemente.
Prurigo pigmentosa, also known as Nagashima disease or keto rash, is a rare inflammatory skin disease initially described by Nagashima et al in 1971. Prurigo pigmentosa typically, but not exclusively, affects young females of East Asian ethnicity, presenting as a symmetrical eruption of urticarial papules on the neck, chest, and back. The papular eruption typically coalesces into a reticulated pattern that repeatedly resolves and recurs, resulting in hyperpigmented skin of cosmetic concern. Prurigo pigmentosa can be triggered by metabolic derangements, including those secondary to ketogenic diets, which have experienced a rise in popularity in recent years.

Prurigo pigmentosa é unha afección da pel que causa protuberancias súbitas, con comezón e vermellas nun patrón similar a unha rede, seguida de manchas escuras. Recentemente, atopáronse evidencias de que Prurigo pigmentosa está asociada á dieta cetoxénica. Pode afectar a persoas de diferentes idades e sexos, con tendencia a ser máis frecuente nas mulleres. Nos casos en que volver a unha dieta regular ou usar tratamentos tópicos non axudan totalmente, os médicos poden prescribir un curso de antibióticos orais, como a doxycycline ou a minocycline (100 mg dúas veces ao día durante 1 ou 2 meses).

Lately, some evidences were founded that Prurigo pigmentosa is associated with the ketogenic diet. It can affect people of different ages and genders, with a tendency to be more common in females. In cases where returning to a regular diet or using skin treatments doesn't fully help, doctors may prescribe a course of oral antibiotics like doxycycline or minocycline (100 mg twice daily for 1 to 2 months).
