Cutaneous eruptions are among the most common immune-related adverse events (irAEs) associated with anti-programmed cell death protein 1/programmed cell death ligand 1 therapy, and are often clinically and histologically characterized as lichenoid. Nonlichenoid patterns may also occur and are likely to be encountered by surgical pathologists, given the increasing clinical use of these agents. The purpose of this study is to describe the histopathologic features of nonlichenoid cutaneous irAEs from patients receiving anti-programmed cell death protein 1/programmed cell death ligand 1 therapies for a variety of underlying advanced malignancies...

Direct immunofluorescence (DIF) on frozen tissue (DIF-F) is the method of choice for the identification of immune deposits present in skin and other tissues. DIF can also be performed on formalin-fixed paraffin-embedded tissue (DIF-P) after antigen retrieval with proteases and has proven to be of value in renal pathology. However, its utility in skin biopsies has not been fully examined. In this study, we performed DIF-P on 60 skin biopsies that comprised of bullous pemphigoid (n = 18), pemphigoid gestationis (n = 1), pemphigus (n = 7), linear IgA disease (n = 7), vasculitis (n = 20), lupus erythematosus (n = 3), and dermatitis herpetiformis (n = 4) cases...

Itch which is one of the major, subjective symptoms in a course of bullous pemphigoid and dermatitis herpetiformis makes those two diseases totally different than other autoimmune blistering diseases. Its pathogenesis is still not fully known. The aim of this research was to assess the role of IL-31 in development of itch as well as to measure its intensity. Obtained results, as well as literature data, show that lower concentration of IL-31 in patients' serum may be correlated with its role in JAK/STAT signaling pathway which is involved in development of autoimmune blistering disease...

Pemphigus vulgaris (PV) is a chronic autoimmune bullous disease characterized by the formation of suprabasal cleavage and acantholysis. As this disease almost always affects the oral mucosa, conventional cytological smears of oral lesions can be used for the initial diagnosis of PV. We report two cases of PV that were initially diagnosed based on cytological smears of an oral sample. As atypical squamous cells were present even in the liquid-based cytological (LBC) smears of the oral lesion in these two cases, this ultimately led to the misinterpretation of squamous cell carcinoma...

BACKGROUND: Autoimmune bullous disorders (AIBDs) are a heterogeneous group of diseases which are rarely seen in children. Studies concerning the immunobullous diseases in pediatric patients are scarce. AIMS AND OBJECTIVES: In this study, we aimed to investigate the clinical features and treatment outcomes of AIBDs in children. MATERIALS AND METHODS: The electronic records of the patients in our AIBDs outpatient clinic were retrospectively reviewed...

We were fascinated to read the observations of Bandino et al. who described two patients who developed keratoacanthomas and squamous cell carcinoma in association with bullous pemphigoid-like lesions after treatment with PD-1 inhibitors, nivolumab or pembrolizumab, in a recent issue of the Journal. Herein we report two patients with no prior history of skin cancer who developed eruptive keratoacanthomas in the setting of lichenoid skin toxicity after starting nivolumab.

REVIEW
Minna E Kubin, Lars Hellberg, Riitta Palatsi
Bullous pemphigoid (BP) is the most common of pemphigoid diseases caused by autoantibodies against the structures of dermoepidermal junction followed by complement activation, innate immune cell infiltration, neutrophil proteinase secretion and subepidermal blister formation. The first line treatment of BP is topical and systemic glucocorticoids (GC). Regulation of the immune system and inflammatory cells is the main target of GC actions. GCs act through genomic and non-genomic mechanisms. The human glucocorticoid receptor (GR) mediates most of the biologic effects of glucocorticoids: cytosolic GR binds GCs and is capable to bind to glucocorticoid response elements in DNA and either transactivate or transrepress genes depending on the tissue and cell-type...

Arterial gas embolism (AGE) can be clinically devastating, and is most often associated with exposure to changes in ambient pressure, medical procedure or congenital malformation. Here we report a case of AGE in a 78-year-old male without these traditional risk factors. Rather, the patient's history included chronic obstructive pulmonary disease, necrotizing pneumonia, bullous disease and coughing. He was safely treated with hyperbaric oxygen (HBO₂) therapy for AGE, with initial clinical improvement, but ultimately died from his underlying condition...

Given the challenge of clinical diagnosis of bullous skin lesions, this report aimed to discuss the histological changes, the presentation and clinical reasoning for diagnosis of these lesions. At the same time, the importance of the pathology was reviewed to identify these clinical scenarios. In this case report, we highlighted the clinical progression of a case of pemphigus foliaceus. RESUMO Considerando o desafio do diagnóstico clínico de lesões cutâneas de apresentação bolhosa, o presente trabalho procurou discutir as alterações histológicas, a apresentação e o raciocínio clínico para o diagnóstico de tais lesões...

Erythema nodosum leprosum (ENL) may uncommonly present before treatment in patients with multibacillary leprosy. Atypical manifestations are known in ENL and may be clinically misleading. Such wide variations in the clinical presentation of leprosy in reaction make histopathology an important tool for supporting clinical diagnosis. We report bullous ENL presenting as the first manifestation of leprosy in a 30-year-old Indian man diagnosed using histopathology.

BACKGROUND: Pemphigus is a group of autoimmune blistering diseases affecting skin and mucous membranes. While pemphigus is an autoantibody mediated disease, the role of T cells and cytokines in the pathogenesis is being increasingly recognized. OBJECTIVE: This study was conducted to observe alterations in the serum cytokine levels of patients with pemphigus vulgaris (PV), pemphigus foliaceous (PF), paraneoplastic pemphigus (PNP) and compare with bullous pemphigoid (BP) and healthy subjects...

Belén Lozano-Masdemont
Membranous, bullous, or cystic aplasia cutis congenita is a clinical subtype of aplasia cutis, covered with a membranous or glistening surface. A male newborn presented at birth with two flat lesions on the left parietal scalp, surrounded by a rim of terminal hairs. Physical examination revealed two translucent papules. On dermoscopy, they showed a reddish background, thin, lineal vessels and, remarkably few hair bulbs could be seen because of the translucency of the lesion. No skull bone and brain defects were found...

E Amsler, A Soria
Allergy to beta-lactam antibiotics is a common condition and about 10% of patients report being allergic to penicillin. However, this diagnosis is largely overestimated. Two types of allergy should be distinguished and include immediate hypersensitivity that can lead to anaphylactic shock and delayed hypersensitivity, ranging from the most common maculopapular exanthema to severe bullous toxidermia or life-threatening DRESS. Allergy challenge with oriented skin tests according to the clinical features, supplemented with oral challenge in the absence of contraindication, will confirm or invalidate the diagnosis of beta-lactam allergy and will help to identify if necessary safe alternatives to beta-lactams...

A young patient presented himself to the emergency department with sudden-onset, breathing-dependent right-sided thoracic pain. The auscultation revealed diminished breath sounds on the right. The radiograph showed a pneumothorax which was immediately dealt with chest tube drainage. The CT scan of the thorax showed minuscule subpleural bullae. Video-assisted thoracoscopic surgery (VATS) was performed due to persistent fistulae formation through the drain. The subpleural, bullous and emphysematous changes were histologically confirmed...
