ReferencesPrurigo pigmentosa 是一種罕見的發炎性皮膚病，由 Nagashima 等人於 1971 年首次描述。它表現為呈對稱分布於頸部、胸部和背部的凸起紅色腫塊狀皮疹。這些腫塊常呈網狀分布，時隱時現，且會在皮膚上留下深色斑塊。Prurigo pigmentosa 可能與代謝變化有關，例如近年流行的生酮飲食所致的代謝改變。
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 是一種皮膚病，會導致突然出現發癢的網狀紅色腫塊，隨後出現黑斑。最近，有證據顯示 Prurigo pigmentosa 與生酮飲食相關。此病可影響任何年齡與性別的人，女性較常見。若恢復正常飲食或使用局部皮膚治療仍無效，醫師可能會開口服抗生素，如多西環素或米諾環素（每次 100 毫克，每天兩次，持續 1 至 2 個月）。
Prurigo pigmentosa is a skin condition causing sudden, itchy, red bumps in a net-like pattern followed by dark spots. 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).
