The patient was a 44-year-old female. She was diagnosed as having systemic lupus erythematosus at the age of 21 years and had been receiving systemic steroid treatment (5 mg prednisolone/day). Nodules began to appear on her neck, chest and back from June in 2000, and she was referred to our clinic for examination and treatment. Examination of a biopsy sample of an eruption on the neck revealed mucin deposition in the dermis. Based on the clinical and histopathological findings, she was diagnosed as having typical nodular cutaneous lupus mucinosis. The dose of steroid was increased, and the eruptions gradually disappeared.
