Mucous Membrane Pemphigoid in a Nonagenarian: A Case Report.

Mucous membrane pemphigoid is a rare autoimmune blistering disease characterized by post-bullous erosion of mucous membranes. Herein, we present a case of a nonagenarian man who was referred to our department of dermatology presenting with painful erosion of the buccal mucosa. Physical examination revealed palate erosion associated with erosion of the buccal mucosa.

Pustular Lichenoid Eruptions Induced by Immune Checkpoint Inhibitors: Two Case Reports and a Review of the Literature.

Immune checkpoint inhibitors (ICIs) have become the standard treatment for many types of cancer. After several years of using these therapies, many adverse events related to ICIs have been observed. Dermatologic toxicities such as nonspecific morbilliform rash, vitiligo, Stevens-Johnson syndrome/toxic epidermal necrolysis, and more rarely, lichenoid eruptions have been described in the literature.

Clinical Features, Histological Characteristics, and Disease Outcomes of Mycosis Fungoides in Children and Adolescents: A Nationwide Multicentre Cohort of 46 Patients.

Background: Our objective was to describe the clinical, histological characteristics, and disease outcome of a cohort of mycosis fungoides (MF) diagnosed during childhood including disease status at adulthood.

Methods: This is a retrospective multicentre survey of patients aged under 18 years at diagnosis with histologically confirmed MF. Patients' clinical and histological characteristics, treatments, and disease outcome (for patients followed for more than 12 months) were analysed.

Successful use of rituximab for refractory hemophagocytic lymphohistiocytosis in a melanoma patient treated with targeted therapy.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease characterized by aberrant immune hyperactivation of T CD8 lymphocytes and macrophages driven by cytokine dysfunction. We report a 64-year-old man, with advanced BRAF-mutant melanoma treated by combined targeted therapies who had a recalcitrant and cortico-dependent Epstein-Barr virus (EBV)-induced HLH. One rituximab cycle led to a rapid and prolonged HLH remission which allowed to switch the targeted therapy for immunotherapy rituximab thus makes it possible to limit the use of corticosteroids, which limits the effectiveness of immunotherapy.

How Do Experts Treat Patients with Bullous Pemphigoid around the World? An International Survey.

Many treatments are currently proposed for treating patients with bullous pemphigoid (BP). We assessed treatment modalities of BP depending on the different countries, BP extent, and patients' comorbidities. We surveyed worldwide experts about how they treat patients with BP.

Updated S2 K guidelines for the management of bullous pemphigoid initiated by the European Academy of Dermatology and Venereology (EADV).

Background: Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering disease of the skin and mucous membranes. This disease typically affects the elderly and presents with itch and localized or, most frequently, generalized bullous lesions. A subset of patients only develops excoriations, prurigo-like lesions, and eczematous and/or urticarial erythematous lesions.

Mixed Individual-Aggregate Data on All-Cause Mortality in Bullous Pemphigoid: A Meta-analysis.

Importance: The 1-year standardized mortality ratio (SMR) of bullous pemphigoid (BP) has been reported as 2.15 to 7.56 and lower in the US than in Europe.

Multiple cutaneous ulcers revealing a primary cutaneous Epstein-Barr virus-positive diffuse large B-cell lymphoma.

Primary cutaneous EBV-positive diffuse large B-cell lymphoma is an exceptional and aggressive neoplasia with a poorer prognosis than other cutaneous lymphoma. Our observation points out the rarity of the presentation and the dismal clinical course.

Panniculitis in a Woman With Opportunistic Pulmonary Coinfection by Pneumocystis jirovecii and Cryptococcus neoformans: 18F-FDG PET/CT Revealing the Infection and Assessing Treatment Response.

A 56-year-old woman, with history of psoriasis well controlled on ustekinumab, underwent 18F-FDG PET/CT to explore first onset of histologically proven skin panniculitis of unknown origin. PET/CT showed high uptake in panniculitis lesions in limbs and in a lung opacity suggestive of pneumonia. Based on PET/CT findings, a bronchoalveolar lavage revealed pulmonary coinfection by Pneumocystis jirovecii and Cryptococcus neoformans.
