Histopathology of autoimmune bullous dermatoses: What's new?

Hum Pathol 2022 Jun 25. Epub 2022 Jun 25.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA; Department of Dermatology, Mayo Clinic, Rochester, MN, USA. Electronic address:

Autoimmune bullous dermatoses are characterized by the presence of tissue-bound and often circulating pathogenic autoantibodies targeting structural components of the skin and/or mucous membranes. The diagnostic workup for this heterogeneous group of disorders consists of a multi-step process, of which the light microscopic examination is a crucial component. This review is organized following a classification scheme that is based on two main histopathologic features, namely level of intraepithelial split and composition of the inflammatory infiltrate.

A literature review on Janus kinase (JAK) inhibitors for the treatment of immunobullous disorders.

Int Immunopharmacol 2022 Jun 16;110:108923. Epub 2022 Jun 16.

Rasool Akram Medical Complex Clinical Research Development Center (RCRDC), School of Medicine, Iran University of Medical Sciences, Tehran, Iran; Skin and Stem Cell Research Center, Tehran University of Medical Sciences, Tehran, Iran. Electronic address:

Janus kinases (JAKs) are a group of intracytoplasmic tyrosine kinase proteins that bind to the cytoplasmic part of the transmembrane cytokine receptors and regulate signaling. The pathophysiology of various autoimmune and autoinflammatory conditions relies on JAK/STAT signaling and therefore, the inhibition of JAK/STAT pathways can be a promising treatment for such diseases, especially inflammatory skin conditions. The current study aimed to evaluate the efficacy of JAK inhibitors in the treatment of immunobullous diseases, including pemphigus, pemphigoid, dermatitis herpetiformis, and epidermolysis bullosa.

Comprehensive review on the pathophysiology, clinical variants and management of pemphigus (Review).

Exp Ther Med 2021 Nov 20;22(5):1335. Epub 2021 Sep 20.

Department of Oral Medicine and Oral Dermatology, 'Grigore T. Popa' University of Medicine and Pharmacy, 700115 Iași, Romania.

Pemphigus represents a group of chronic inflammatory disorders characterized by autoantibodies that target components of desmosomes, leading to the loss of intercellular adhesion between keratinocytes and causing intraepithelial blistering. The pemphigus group consists of four main clinical types with several variants: pemphigus vulgaris (with pemphigus vegetans and pemphigus herpetiformis as variants), pemphigus foliaceus, paraneoplastic pemphigus and IgA pemphigus (with two clinical variants: intraepidermal neutrophilic IgA dermatosis and subcorneal pustular dermatosis). Genetic factors are involved in the pathogenesis, with HLA-DR4 (DRB1*0402) and HLA-DRw6 (DQB1*0503) allele more common in patients with pemphigus vulgaris, HLA class II DRB1*0344 and HLA Cw*1445 correlated with paraneoplastic pemphigus, and HLA-DRB1*04:01, HLA-DRB1*04:06, HLA-DRB1*01:01, HLA-DRB1*14, associated with a higher risk of developing pemphigus foliaceus.

Dermatol Ther 2021 09 14;34(5):e15032. Epub 2021 Jul 14.

Department of Specialized, Clinical and Experimental medicine, Division of Dermatology, University of Bologna, Italy.

Autoimmune bullous diseases are a heterogeneous group of diseases characterized by the development of cutaneous and mucosal vesicles, blisters, and finally erosions. The common pathogenetic mechanism is the presence of autoantibodies targeting structural proteins of the skin and mucous membranes (demosomes and hemidesmosomes): in the case of pemphigus, the antigens are intraepidermal, whereas in the case of pemphigoid, dermatitis herpetiformis, and epidermolysis bullosa acquisita they are subepidermal. Mucosal involvement typically affects the oral and ocular mucosa, but in some cases, the upper airways or the upper digestive tract are affected. Read More
