Localized Pemphigus Foliaceus with Unilateral Facial Involvement

Localized facial pemphigus foliaceus presenting in a dermatomal distribution: A case report

Pemphigus foliaceus is a superficial autoimmune blistering disorder of the skin. Localized forms of pemphigus foliaceus are rare. Only a few cases have been described. We report a case of an 81-year-old man with pemphigus foliaceus who initially presented with localized dermatomal facial lesions. Due to this atypical presentation, making the diagnosis was challenging. To our knowledge, this is the first case of localized pemphigus foliaceus with a dermatomal distribution to be recorded.

Role of auto-antibodies in the mechanisms of dengue pathogenesis and its progression: a comprehensive review

A complex interaction among virulence factors, host-genes and host immune system is considered to be responsible for dengue virus (DENV) infection and disease progression. Generation of auto-antibodies during DENV infection is a major phenomenon that plays a role in the pathophysiology of dengue hemorrhagic fever and dengue shock syndrome. Hemostasis, thrombocytopenia, hepatic endothelial dysfunction, and autoimmune blistering skin disease (pemphigus) are different clinical manifestations of dengue pathogenesis; produced due to the molecular mimicry of DENV proteins with self-antigens like coagulation factors, platelets and endothelial cell proteins. This review elaborately describes the current advancements in auto-antibody-mediated immunopathogenesis which inhibits coagulation cascade and promotes hyperfibrinolysis. Auto-antibodies like anti-endothelial cell antibodies-mediated hepatic inflammation during severe DENV infection have also been discussed. Overall, this comprehensive review provides insight to target auto-antibodies that may act as potential biomarkers for disease severity, and a ground for the development of therapeutic strategy against DENV.
