diflucortolone and Mucinoses

Abstract Reticular erythematous mucinosis (REM) is a rare chronic mucinosis. Histologically, the presence of mucin in the upper dermis is the most specific feature. A 73-year-old woman presented to our outpatient clinic with a 4-year history of netlike macular erythema with slight edema on her left arm. She was diagnosed as having REM on the basis of the clinical picture and histological findings. She was treated with ultraviolet B irradiation using the VTRAC Excimer Lamp system with favorable response. This is the first reported case that was treated with a 308-nm excimer lamp.

We describe an 81-year-old Japanese patient with erythroderma overlapping with widespread and symmetrical deposits of mucin in the upper dermis. Clinically, the mucinous lesions on the nape and upper trunk were localized papular mucinosis. Histologically, there was a perivascular infiltrate of lymphohistiocytic cells mingled with plasma cells in the upper dermis but no sclerosis. Immunohistochemical staining revealed that more than 90% of these infiltrating plasma cells produced immunoglobulin lambda-chain. Both the erythroderma and generalized mucinosis responded to topical steroid and PUVA therapy. To the best of our knowledge, this is the first case of erythroderma accompanied by generalized mucinosis.
