Abstract

Sinus histiocytosis with massive lymphadenopathy(SHML) is a benign, generally selflimited pseudolymphomatous disease that typically appears with cervical massive lymphaclenopathy. Extranodal involvement including skin occurs in the 28% of the cases. We report a case af SHML in 51 year-old male who had several, prominent firm masses ranging from 1-10cm in the cervical, axillary, inguinal areas and multiple, plum colored nodules and plaques in the face, trunk for about 10 years. The histopathological findings of cervical lymph node, facial nodule showed dense heavy infiltration of large histiocytes with abundant pale eosinophilic cytoplasm in the subcapsular and medullary sinuses of lymph node and dermis of skin. No atypical cells suggesting malignancy is seen in the infiltrates. The patient had been treated with combination of prednisolone and vinblasstine, but he expired 1 month later.
