Prurigo pigmentosa is a rare inflammatory cutaneous disorder associated with ketosis that resolves with reticulate hyperpigmentation. A 19-year-old man was admitted to the hospital with diabetic ketoacidosis. He also had developed reticulate papules coalescing into plaques over the posterior neck, back, and abdomen. Histopathological findings consistent with the clinical findings suggested the diagnosis of prurigo pigmentosa. After treatment with topical triamcinolone and oral doxycycline along with resolution of his ketosis after insulin administration, the patient's rash healed with reticulate hyperpigmentation.
色素性痒疹是一种罕见的炎症性皮肤疾病，与酮症有关，在出现网状色素沉着后可自行消退。一名 19 岁男性因糖尿病酮症酸中毒入院。他还在后颈部、背部和腹部出现融合成斑块的网状丘疹。组织病理学检查结果与临床表现一致，提示诊断为色素性痒疹。在给予胰岛素治疗以纠正酮症后，患者接受了曲安奈德外用和多西环素口服治疗，皮疹痊愈并出现网状色素沉着。
