Case History A 67-year-old Sikh male was diagnosed with pemphigus vulgaris in 1996 when he presented with oral erosions. His disease remained controlled on long-term, low-dose prednisolone therapy. In 2004, he developed a verrucous keratotic plaque over the occipital region of his scalp and it had been gradually enlarging (Fig. 1). Biopsies were performed in 2004 and 2008 and histological featu...

Darier's disease is a rare genodermatosis caused by a defect in ATP2A2 gene located on chromosome 12q23-23 (1). This somatic mutation rarely occurs in the postzygotic phase of embryogenesis, leading to cutaneous mosaicism for the disease. The mosaic form of Darier's disease is also called linear Darier's disease and clinically presents with linear, zosteri-form or localized patterns located on ...

The mucosal-dominant variant of pemphigus vulgaris (MPV) is an autoimmune disease characterized by oral mucosal blistering and circulating pathogenic IgG antibodies against desmoglein 3 (Dsg3), resulting in life-threatening bullae erosion formation. Recently, microRNAs (miRNAs) have emerged as promising players the diagnosis prognosis several pathological states. For first time, we identified a...

Darier disease (DD) is a dominantly inherited skin disorder. It characterized by painful and malodourous plaques papules on the of patients. The typical features DD include: acantholysis abnormal keratinization. These histological are due to mutations in gene, ATP2A2, which encodes sarco/endoplasmic reticulum (ER) Ca2+-ATPase isoform 2 (SERCA2), pump ER. This leads malformation desmosomes adher...

Pemphigus vulgaris (PV) is an acquired autoimmune blistering disease characterized by the production of autoantibodies targeting desmosomal cadherins, primarily desmoglein 1 and 3, leading to acantholysis. The etiology PV multifactorial, including genetic susceptibility. This retrospective study aimed evaluate association HLA class II alleles examine impact PV-associated on concentration anti-d...

p38 mitogen activated protein kinase (p38 MAPK) signaling plays a major role in the modulation of immune-mediated inflammatory responses and therefore has been linked with several autoimmune diseases. The extent of the involvement of p38 MAPK in the pathogenesis of autoimmune blistering diseases has started to emerge, but whether it pays a critical role is a matter of debate. The activity of p3...

A 26-year-old woman presented with a 5-month history of painful oral erosions and a 1-month history of widespread flaccid vesicles over her face and torso. A biopsy specimen of a skin lesion revealed suprabasal acantholysis. The diagnosis of pemphigus vulgaris (PV) was confirmed by a positive intercellular (IC) antibody titer. The patient was treated with prednisolone (30-45 mg/d) combined with...
