IgA Paraneoplastic Pemphigus in Angioimmunoblastic T-cell Lymphoma with Antibodies to Desmocollin 1, Type VII Collagen and Laminin 332

Linear IgA dermatosis in association with angioimmunoblastic T‐cell lymphoma infiltrating the skin: A case report with literature review

“…Those eruptions could also be linked to drug administration . To the best of our knowledge, six cases of blistering skin disease associated with AITL have been previously described, with available information for only four of them. These are summarized in Table .…”

Case of paraneoplastic pemphigus with immunoglobulin (Ig)G and IgA antibodies to various antigens

“…5 In addition, sporadic reports of atypical PNP cases with IgA autoantibodies were also reported. [5][6][7][8][9] The serum of one patient showed IgA, but not IgG, anti-cell surface antibodies by IIF. 6 As IgA antibodies reacted with COS-7 cells transfected with Dsc2, the authors proposed the term IgA PNP.…”

“…As IgA antibodies reacted with COS‐7 cells transfected with Dsc2, the authors proposed the term IgA PNP. The term IgA PNP was also used for a case which showed various autoantibodies, including IgA autoantibodies to Dsc1 . In addition, a PNP case showed both IgG and IgA anti‐cell surface antibodies in IIF, and another PNP case showed IgA and IgG antibodies to a panel of known and unique antigens …”

Pemphigus

“…19,20 Furthermore, this disease has also been related to adenocarcinoma of the colon, pancreas, lung, prostate, breast, and liver and squamous cell carcinomas of the tongue, uterus, kidney, and Kaposi sarcoma. 19,42,[61][62][63][64] Pemphigus can precede or present after the onset of malignancy and may have independent clinical courses. In almost all cases, it appears in the form of PV with severe mucosal involvement.…”
