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.

Mixed muco-cutaneous pemphigoid: Clinical and immunological features of 15 cases.

Introduction: We describe a series of patients whose auto-immune bullous skin disease (AIBD) of the dermal-epidermal junction (DEJ) was characterized by clinical, immunological and ultrastructural features intermediate between bullous pemphigoid (BP) and mucous membrane pemphigoid (MMP), and a recalcitrant course.

Patients And Methods: From the database of the French reference centre for AIBD, we screened all the patients who were referred for an AIBD of the DEJ with a mucosal involvement, who neither met the diagnostic criteria for the diagnosis of BP, nor were typical of MMP. Sera were analysed by NC16A-ELISA and immunobloting against the C-terminal and LAD-1 parts of BP180.

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.

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.

Reactive Eccrine Syringofibroadenomatosis Associated With Venous Leg Ulcers: A Case Report and Literature Review.

Eccrine syringofibroadenoma (ESFA) is a rare adnexal tumor deriving from the acrosyringeal portion of the eccrine duct. Five subtypes of ESFA were described including a reactive form. Reactive ESFAs are associated with inflammatory and neoplastic dermatoses.

Cutaneous Melanocytoma With CRTC1-TRIM11 Fusion: Report of 5 Cases Resembling Clear Cell Sarcoma.

We report 5 cases of primary intradermal nodular unpigmented tumors with a melanocytic immunophenotype associated with a novel CRTC1-TRIM11 fusion. Clinically, the cutaneous nodules were slowly growing in 3 women and 2 men (25 to 82 y old, median, 28 y) with no specific topography. Lesion size ranged from 4 to 12 mm (median, 5 mm).
