[Changes in the skin in transplantation versus host reaction. 2. Our clinical findings from observations using light microscopy and electron microscopy].
A clinical, light microscope and electron microscope study of skin changes was undertaken in 19 patients after bone marrow transplantation. Thirteen of the total number of 19 patients were clinically suspect of the acute and 6 of the chronic form of GvHD. Skin biopsy between the seventh and thirtieth day following transplantation confirmed the diagnosis of the acute form of GvHD in 7 of the 19 patients. In 4 of the 6 patients in whom skin biopsy did not verify the diagnosis of the acute form of GvHD, completely atypical rash in addition to signs of GvHD of the liver and intestines developed between the 30th and 50th day following transplantation. In all 6 patients who were clinically suspect of the chronic form of GvHD, skin biopsy performed some 4-10 months after transplantation confirmed the diagnosis of chronic, sclerodermoid or lichenoid GvHD. Furthermore in 71% of the patients with histologically verified chronic form of skin GvHD, symptoms of liver and intestine GvHD were present too at the time of the skin biopsy. With regard to the fact that histologically the least reliable seems to be the diagnosis of Grade 1 cutaneous GvHD, the authors recommend that regular dermatological follow-up examinations be made in the period of 7 to 50 days following transplantation in addition to skin biopsy in the case of appearance of any rash. Electron microscopy revealed in both forms of GvHD, the acute and the chronic, the most significant epidermal changes, i.e. degeneration of the cellular organelles and the appearance of numerous intracytoplasmic vacuoles.
