background: trichophyton verrucosum is a zoophilic fungus with a worldwide distribution. our aim was to investigate the proliferative effect of antigenic compounds of t. verrucosum on dermis fibro blasts and endothelial cells. methods: t. verrucosum was cultured in scc medium and was then transferred to a broth medium. surface antigens of this fungus were separated using the freeze and thaw met...

Histopathological examination of the ichthyotic skin showed perivascular dermal lymphoid cell infiltration in the superficial dermis and nodular and dense lymphoid cellular infiltration in the deep dermis. Lymphoid cells were CD3+ and CD20with a loss of CD7 expression. There were numerous (>25%) large, anaplastic cells with CD30 positivity among the lymphoid infiltrate. Clonal expansion of T ce...

elephantiasis nostras verrucosa (env) is a rare condition in which hyperkeratosis, fibrosis and disfiguration of dermis occurs. it is caused mostly by non infectious diseases such as surgery, trauma, tumors, and venous obstructions. to our knowledge there is not any case report of env in middle east region. in this patient, env caused by trauma and patient presented with enlargement of right lo...

P oters CONCLUSION: Previous studies were consistent with our results for both the vertical and horizontal dermal forces. In our study, the tensile strength of the tested human abdominal dermis samples, both aesthetic and post-bariatric, were superior to the tested commercial meshes. Therefore, in some selected cases, abdominal dermis could be an alternative tool in abdominal reconstruction dur...
