IgD, cyclooxygenase-2 and ribosomal protein S6-PS240 immune response in a case of early psoriasis
Journal Title: Nasza Dermatologia Online - Year 2018, Vol 9, Issue 1
Abstract
Psoriasis is an inflammatory skin disease. Five classic types of psoriasis have been defined: plaque, inverse, pustular, guttate, and erythrodermic. The early psoriasis immunologic skin immune response is not well understood. Here we aim to show an immune and cell signaling response in a case of early psoriasis. A 56 year old female presented with a desquamative lesion on her right leg. A skin biopsy for hematoxylin and eosin (H&E) and immunohistochemistry (IHC) staining was taken. The diagnosis indicated early psoriasis, and IHC showed positive IgD staining in the epidermal corneal layer, as well as positive staining with ribosomal protein S6-pS240 (RIBO) in the hyperproliferative epidermis. Cyclooxygenase-2 (COX-2) was also very positive in the granular layer in spots, at the basement membrane zone of the skin and in the inflammatory infiltrate in the dermis subjacent to hyperproliferative psoriatic areas. In an early case of psoriasis, we confirmed the presence of IgD, RIBO and COX-2. Each molecule seems to be playing a role in inflammation and intracellular signaling pathways in early psoriasis. The role of IgD is unknown, and this case brings to light the complexity of the pathologic changes occurring in early psoriatic lesions.
