Skin reactions associated with oral coumarin-derived anticoagulants are an uncommon occurrence. Leukocytoclastic vasculitis (LV) is primarily a cutaneous small vessel vasculitis, though systemic involvement may be encountered. We report 4 patients with late-onset LV probably due to warfarin. All 4 patients presented with skin eruptions that developed after receiving warfarin for several years. ...

Introduction. Buschke-Ollendorf syndrome (BOS) is an uncommon syndrome characterized by osteopoikilosis and other bone abnormalities, accompanied by skin lesions, most frequently connective tissue nevi. BOS is caused by mutations in the LEMD3 gene, which encodes the inner nuclear membrane protein Man1. We describe a unique case of osteopoikilosis associated with late-onset localized scleroderma...

OBJECTIVE To report a case of late-onset self-healing Langerhans cell histiocytosis. CASE DESCRIPTION A 4½-month-old female patient presenting with an eythematopurpuric eruption underwent a skin biopsy for histopathology and was first diagnosed with isolated cutaneous Langerhans cell histiocytosis. Her lesions regressed within a few months and she was retrospectively diagnosed with late-onset...

A 59 year old man is presented with a diagnosis of dermatitis herpetiformis. Duodenal and skin biopsy specimens from blisters of both recent and late onset were collected before treatment. Electron microscopy, immunohistochemistry, and in situ hybridisation were performed to analyse the presence of activated eosinophils and the local synthesis of interleukin 5 (IL5). Parallel state of eosinophi...

skin lesions were found in two 3–4-year-old holstein cows in a dairy farm in shiraz. lesions were distributed mostly around the neck, forelimbs, hindlimbs, and bilateral of midline portion and varied from nodule-like structure to patch with extensive accumulation of crust. skin scraping samples were taken from each animal and direct smears were prepared, stained with giemsa and observed under a...

Non-tuberculous mycobacterial skin infections have an increasing incidence. In immunocompetent patients, they usually follow local trauma. We present a case of cutaneous Mycobacterium abscessus infection following mesotherapy. The lesions were successfully treated with a combination of clarithromycin, ciprofloxacin, and doxycycline. Atypical mycobacterial infection should be suspected in patien...

BACKGROUND Although mild early cutaneous transient reactions to vaccinations are common, late-onset chronic lesions have been scarcely reported. We report herein a series of 9 patients presenting with cutaneous and subcutaneous pseudolymphoma. OBSERVATIONS Nine patients presenting with late-onset, chronic skin lesions occurring at the site of antihepatitis B (8 cases) and antihepatitis A (one...

OBJECTIVE We aimed to evaluate the clinical features of sclerodermatous chronic graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (AHSCT). METHODS We retrospectively analyzed 423 patients who underwent AHSCT. We assessed age, sex, pre-transplant diagnosis, conditioning regimen, GVHD prophylaxis, and occurrence of acute GVHD (aGVHD), chronic lichenoid an...
