Cutaneous diphtheria from 2018 to 2022: an observational, retrospective study of epidemiological, microbiological, clinical, and therapeutic characteristics in metropolitan France.

The incidence of diphtheria has been rising over the past decade, particularly in its cutaneous form. A clinical review of the case series was therefore required. We reviewed the epidemiological, clinical, microbiological and therapeutic data of cutaneous diphtheria cases, in adult patients living in metropolitan France with a skin sample positive for corynebacteria of the complex between 2018 and 2022.

Trichoblastic Carcinosarcoma of the Skin: A Case Report and Literature Review.

An 83-year-old man presented to the dermatology department for an ulcerated skin lesion of the back that had been increasing in size during the past 11 years. The physical examination revealed a well-defined, fleshy, reddish plaque measuring 10 × 20 cm in diameter with erosions and black areas on the surface. The patient underwent surgical excision with margins of 10 mm followed by a skin graft.

[The colloid milium: An observation associated with trichinosis].

The colloid milium has four clinical forms: adult colloid milium, juvenile colloid milium, paracolloid (or nodular colloid degeneration) and pigmented colloid milium. We report the case of an adult colloid milium in a man of 56, who presented episodes of diffuse pruritus associated with myalgia and digestive disorders, indicative of trichinosis. He also developed gradually over the past 10 years, yellowish injuries in the mandibles and neck for whom histology objectified a colloid milium.

Teledermatology in Low-Resource Settings: The MSF Experience with a Multilingual Tele-Expertise Platform.

Introduction: In 2010, Médecins Sans Frontières (MSF) launched a tele-expertise system to improve the access to specialized clinical support for its field health workers. Among medical specialties, dermatology is the second most commonly requested type of tele-expertise. The aim of the present study was to review all MSF teledermatology cases in the first 4 years of operation.

A 78-year-old woman with an acute eosinophilic gastroenteritis.

Eosinophil accumulation in the gastrointestinal tract is a common feature of numerous disorders including mainly parasitic infection, drug-induced allergic reactions, inflammatory bowel disease, and various connective tissue disorders. Digestive tissue eosinophilia requires thorough searching for secondary causes that may be specifically treated with antibiotics, dietary and drug elimination or immunosuppressive therapy. Frequency, prognosis and therapeutic implications must guide the diagnostic course.

Persisting mixed cryoglobulinemia in Chikungunya infection.

Background: Chikungunya virus (CHIKV), an arbovirus, is responsible for a two-stage disabling disease, consisting of an acute febrile polyarthritis for the first 10 days, frequently followed by chronic rheumatisms, sometimes lasting for years. Up to now, the pathophysiology of the chronic stage has been elusive. Considering the existence of occasional peripheral vascular disorders and some unexpected seronegativity during the chronic stage of the disease, we hypothesized the role of cryoglobulins.
