피부 루푸스 점액증 1예

Abstract

Cutanenous lupus mucinosis is a rare variant of lupus erythematosus eruptions. A 36-year-old female presented with 1-2 cm sized, skin colored, multiple nodules on the back for 1 year. She was diagnosed as systemic lupus erythematosus 10 years ago. Complete blood count showed lymphopenia. Antinuclear antibody(ANA) was positive at a titer of 1:640. Anti-Sm and ds-DNA were also positive. Histopathological findings showed that the collagen fibers in the upper dermis were loosely arranged and separated by amorphous materials. These materials were all positive for alcian blue staining. This case is compatible with cutaneous lupus mucinosis.
