title: [Significance of histopathologic analysis of skin lesions in scleromyxedema. Light microscopy, electron microscopy, immunohistochemistry and immunofluorescence microscopy].
abstract: Scleromyxedema (SM) may be considered as a possible disease entity in the differential diagnosis of scleroderma. Clinical data and the results of light, immunohistochemical, immunofluorescence and electron microscopic study of skin biopsies taken from a 53-year old patient with SM are reported. In the patient with SM in which abnormal serum paraprotein was not identified, the skin biopsy showed mucinous material in the dermis and proliferation of fibroblasts accompanied by mild dermal sclerosis. Immunofluorescence showed scanty granular IgG along the epidermal basement membrane and IgG and C1q focally along the connective tissue fibres in the dermis of clinically involved skin. In addition to clinical findings, detailed skin biopsy studies including contemporary techniques can contribute to the diagnosis of the disease.
