One case report of mycosis fungoides with the clinical presentations of reticular erythematous mucinosis

A 42-year-old female patient presented with erythemas over the trunk and arms for 14 years and the skin lesions progressed and deteriorated lasting for 5 years.Six year ago,the first histopathological examination showed deposits of acid mucopolysaccharides in the papillary and reticular dermis with alcian blue staining positive.Then the diagnosis of reticular erythematous mucinosis (REM) was made at that time.Physical examination revealed slightly infiltrated plaque-like erythema on the face,scalp,neck,trunk and limbs,some of them coalesced in a reticular pattern.The purple-red plaques were also found on the abdomen.The recent biopsy of the plaque showed that atypical lymphocytes were infiltrated in a lichenoid pattern in the dermis.The lymphocytes infiltrated into epidermis and formed the Pautrier's microabscesses.The immunohistochemistry study found the infiltrated lymphocytes were positive to LCA (+++) and CD45RO (+++).The patient was diagnosed as mycosis fungoides.
