Аннотация
CONTEXT: Pompholyx (called dyshidrosis by some) is one of the most common conditions and its immune response is presently poorly understood.
CASE REPORT: We describe a 58 year old African American female with a clinical history of rheumatoid arthritis and type II diabetes who presented a chronic five-year, itchy vesicular/blistering rash involving her hands and feet. A lesional skin biopsy was taken for hematoxylin and eosin (H & E) analysis. In addition, a multicolor direct immunofluorescence (MDIF) and immunohistochemistry (IHC) studies were performed. The major findings to be reported were: the H & E examination revealed spongiotic dermatitis and pompholix. IHC and MDIF studies demonstrated focally deposits of positive CD45, CD3, CD8, anti myeloperoxidase (MPO), and anti-human IgE, C3C, C3D and anti-human-fibrinogen within the epidermal spongiotic process, as well as around the blood vessels surrounding the inflammatory process especially at the sweat glands and respective ductus. The patient began mycophenolate mofetil therapy, with successful clearing of the palms and soles.
CONCLUSION: The significance of our findings indicates a complex immunological process including complement, MPO and T-cell immune response. In addition, possibly a secondary allergic process for the presence of IgE immune response and possibly aggravation by application of other medicines. Further immunological studies on pompholyx are needed. (Abreu-Velez AM, Pinto FJ, Howard MS. North Am J Med Sci 2009; 1: 117-120).
