Paraneoplastic autoimmune multiorgan syndrome, also known as paraneoplastic pemphigus, has been observed only rarely among children. Correction: Paraneoplastic autoimmune multiorgan syndrome and paraneoplastic pemphigus describe the same spectrum of disease pathology Aimee S. Payne , Michael Kasperkiewicz , Paraneoplastic syndromes of the nervous system are a group of uncommon disorders that develop in some people who have cancer.

Figure 1 Characteristic clinical features of paraneoplastic pemphigus (PNP). Nat.. Originally described by Anhalt as paraneoplastic pemphigus in 1990, paraneoplastic autoimmune multiorgan syndrome (PAMS) is a potentially lethal blistering disease, characterized by polymorphous clinical features, including mucocutaneous erosions, blisters, lichenoid papules, and erythemas. Intractable stomatitis and polymorphous cutaneous eruptions, including blisters and lichenoid dermatitis, are characteristic clinical features caused by humoral and cell-mediated autoimmune reactions. The term "paraneoplastic autoimmune multiorgan syndrome," or PAMS, was suggested in recent studies. Overview. Cummins DL, Mimouni D, Tzu J, et al. Paraneoplastic autoimmune multiorgan syndrome (PAMS) is characterized by a heterogenous group of signs and symptoms including severe desquamative stomatitis, a polymorphous cutaneous eruption, humoral immunity against plakin proteins, contribution of cell-mediated autoimmunity and commonly a progressive respiratory failure. Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to a neoplasm. Nat. Epithelial cell membrane antigens other than DSG1 or DSG3 are targeted by effectors of PAMS autoimmunity. The pathogenesis for this process has been described as development of certain autoimmune reactions against cell wall antigens and proteins. 2004 Oct. 114(4):e513 .

An autoimmune mucocutaneous disease associated with neoplasia. It may display a spectrum of at least 5 different clinical and immunopathological mucocutaneous variants (i.e., pemphigus-like, pemphigoid-like, erythema multiforme-like, graft-vs-host disease-like, and lichen planus-like) and there are evidences . In this regard, it should be noted that these patients usually show a multi-organs involvement and different subsets of auto-antibodies to several tissues [1,3,6]. Lesions may also affect the nasopharynx, oropharynx, and larynx, leading to odynophagia, dysphagia, and hoarseness that require assessment by an ear, nose, and throat specialist. Diagnosis of paraneoplastic pemphigus/paraneoplastic autoimmune multiorgan syndrome (PNP/PAMS) in the setting of erosive or lichenoid mucocutaneous disease. 6. In 2001 Nguyen et al. Recent studies suggest that paraneoplastic pemphigus (PNP) is a heterogeneous autoimmune syndrome involving several internal organs and that the pathophysiological mechanisms mediating cutaneous, mucosal, and internal lesions are not limited to autoantibodies targeting adhesion molecules. Paraneoplastic pemphigus (paraneoplastic autoimmune multiorgan syndrome): clinical presentations and pathogenesis. Paraneoplastic pemphigus (PNP) is a rare but life-threatening mucocutaneous disease mediated by paraneoplastic autoimmunity. Paraneoplastic autoimmune multiorgan syndrome (or paraneoplastic pemphigus) is an autoimmune dis-ease with mucocutaneous manifestations, and is asso-ciated with different tumors (lymphoproliferative disorders such as non-Hodgkin's lymphoma, chronic lymphocytic leukemia, visceral malignancies, Castleman The pathophysi-ological mechanisms of PAMS involve both humoral and cellular autoimmunity responses. Collectively, these processes have been reported as part of paraneoplastic autoimmune multiorgan syndrome (PAMS), and they can occur in the setting of various hematologic malignant tumors, carcinoid tumors, and melanoma. PAMS-associated mortality may occur as a result of autoantibody formation against internal tumors and their infiltration into organs other than the skin lesions that characterize PAMS. This disorder is categorized by the presence of autoantibodies that react against proteins, such as desmoplakins, desmogleins, desmocollins, and others that exist in cellular junctions. (C,D) Polymorphous cutaneous eruptions, with erythematous macules, papules, flaccid bullae, and erosions on the trunk and extremities.

The scan revealed an anterior mediastinal mass, which, on excision, was determined to be an invasive thymoma. Paraneoplastic pemphigus (PNP) (also paraneoplastic autoimmune multiorgan syndrome [PAMS] to denote the systemic nature of the syndrome) is an autoimmune mucocutaneous blistering disease affecting adults or rarely children that generally heralds the presence of an underlying malignancy. Paraneoplastic pemphigus is a rare multiorgan disease of autoimmune causes, usually triggered by neoplasias, mainly of lymphoproliferative origin, such as leukemia and lymphoma.
