An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [[acrodermatitis chronica atrophicans]].
High anti-[[Spirochaete|spirochetal]] [[antibody]] levels (such as [[Immunoglobulin G|IgG]], [[Immunoglobulin G|IgM]] and [[Immunoglobulin A|IgA]]) has been detected at indirect [[immunofluorescence]] and [[enzyme linked immunosorbent assay (ELISA)]]. Among various [[antigens]] in [[borrelia burgdorferi]], [[flagellum]] [[antigen]] is one of the recommended [[serology|serologic evaluation]] in [[Acrodermatitis chronica atrophicans|acrodermatitis chronica atrophicans]] [[patients]]. [[Diagnosis]] of [[Acrodermatitis chronica atrophicans|acrodermatitis chronica atrophicans]] can be excluded if the [[serology|serologic]] evaluataion is negative. [[Borrelia]] itself has been found in some of the [[skin]] samples. When clinical presentations are not clear enough, [[biopsy]] and [[histology|histological]] evaluation can assist. Findings such as [[Plasma cell|plasma cells]], [[histiocytes]] and [[Lymphocyte|lymphocytic infiltration]] plus [[telangiectasia]] and thinning of [[dermis]] and [[epidermis]] are commonly found in [[skin]] [[biopsy|biopsies]].

Overview

High anti-spirochetal antibody levels (such as IgG, IgM and IgA) has been detected at indirect immunofluorescence and enzyme linked immunosorbent assay (ELISA). Among various antigens in borrelia burgdorferi, flagellum antigen is one of the recommended serologic evaluation in acrodermatitis chronica atrophicans patients. Diagnosis of acrodermatitis chronica atrophicans can be excluded if the serologic evaluataion is negative. Borrelia itself has been found in some of the skin samples. When clinical presentations are not clear enough, biopsy and histological evaluation can assist. Findings such as plasma cells, histiocytes and lymphocytic infiltration plus telangiectasia and thinning of dermis and epidermis are commonly found in skin biopsies.
