erythema multiforme

We are currently facing a worldwide epidemic of syphilis. Clinical manifestations that are rarely seen have been encountered, leading the dermatologist to confront unusual clinical conditions in daily practice. Erythema multiforme triggered by syphilis is very rare and is also seldom reported in the literature. We report a case of secondary syphilis in an HIV-positive patient, whose clinical, pathologic and serologic features were consistent with the diagnosis of erythema multiforme triggered by syphilis.

Paraneoplastic pemphigus (PNP), a subset of pemphigus, is a unique autoimmune blistering condition that can affect multiple organs other than the skin. It is a life-threatening disease associated with an underlying malignancy, most commonly of lymphoproliferative origin. The clinical picture may resemble pemphigus, pemphigoid, erythema multiforme, graft-versus-host disease, or lichen planus. The earliest and most consistent finding is a painful, severe, chronic and often recalcitrant stomatitis. Treatment of PNP is difficult...

Lupus erythematosus (LE) is an autoimmune disease which may initially present solely with lip lesions. Due to a wide spectrum of presentation, these features may initially be misdiagnosed as other oral diseases such as lichen planus, erythema multiforme (EM), and actinic cheilitis, leading to a delay in diagnosis and treatment. We discuss a case of severely crusted cheilitis which was initially diagnosed as EM, with subsequent development of subacute cutaneous LE, and progression to systemic LE. We will discuss the clinical and histological features of lupus cheilitis...

Annular urticarial lesions in a child must establish a main differential diagnosis with urticaria multiforme, common urticaria, acute hemorrhagic edema of infancy, erythema marginatum, erythema annulare centrifugum, annular erythema in childhood, erythema multiforme, Sweet's syndrome, Schönlein-Henoch purpura, erythematosus lupus, several systemic vasculitis, and serum sickness.

Autoimmune progesterone dermatitis is a rare cyclic premenstrual reaction to progesterone produced during the luteal phase of the menstrual cycle. The clinical symptoms of autoimmune progesterone dermatitis overlap with other forms of dermatosis such as erythema multiforme, eczema, fixed drug eruption, urticaria, and angioedema. We experienced 3 cases of autoimmune progesterone dermatitis. All patients had a recurrent history of monthly skin eruptions. Skin lesions normally began a few days before menstruation and resolved a few days later...

Resveratrol is a polyphenol which has been gaining momentum in therapeutics in the last years. In this work, we hypothesized that it could act in the prophylaxis and/or treatment of inflammatory lesions of the oral cavity through its delivery from two different formulations of buccal mucoadhesive tablets. This was assessed through permeation studies, in order to verify the drug diffusivity through the buccal mucosa, using a porcine model to predict the human in vivo behavior. We observed that the tablet with a lower percentage of viscosity agents delivered more resveratrol, although a large amount of the drug was found retained within the stratum corneum...

BACKGROUND: Prevalence and incidence of drug eruptions vary around the world and are influenced by some key factors including HIV infection. OBJECTIVE: This study aimed to find the peculiarities of drug eruptions in people living with HIV (PLHIV) and on antiretroviral therapy (ART). METHODS: This was a retrospective cross-sectional study including ART-taking PLHIV, aged 15+ years, followed up between January 2010 and December 2014 at the day-care unit of the Yaoundé Central Hospital, and who presented with drug eruptions after ART initiation...

Erythema multiforme (EM) is a skin condition for which main causes are infectious factors (Herpes simplex virus, Mycoplasma pneumoniae). Anti-plakin auto-antibodies are found in some patients (1) . EM must be distinguished from Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), which are drug-induced in most cases (2-5) . This article is protected by copyright.

BACKGROUND: In severe drug eruptions, precise evaluation of disease severity at an early stage is needed to start appropriate treatment. It is not always easy to diagnose these conditions at their early stage. In addition, there are no reported prognostic biomarkers of disease severity in drug eruptions. The aim of this study was to test whether the thymus and activation-regulated chemokine (TARC) level in serum at an early stage of a drug eruption can serve as a prognostic biomarker of systemic inflammation...

Primary cutaneous aggressive epidermotropic CD8+ cytotoxic T-cell lymphoma (pCAECD8+ CTCL), is an extremely rare, rapidly progressing cutaneous lymphoma, with frequent systemic involvement, first recognized as a distinct clinicopathologic entity by Berti et al in 1999. (1) As the name suggests, this entity has an aggressive behavior and exhibits marked epidermotropism on histopathologic analysis. Conventional treatment modalities for classic CTCL are often ineffective and the prognosis is poor with a median survival of 12 months...

Autoimmune progesterone dermatitis (APD) is a rare disorder characterized by periodic skin lesions that erupt during the luteal phase of the menstrual cycle. Clinical manifestations of APD is caused by an unusual allergy to progesterone and has a wide range of clinical manifestations from eczema and urticaria to angioedema and erythema multiforme. A 46-year-old woman described recurrent, round erythematous plaques on the lower lip, both forearms and buttocks. These skin eruptions waxed and waned for 10 months, reoccurring 3-4 days before menstruation...

A fixed-dose formula that combines Ombitasvir (OBV), Paritaprevir (PTV) and Ritonavir (RTV) has been launched into the field of anti-HCV therapy in Japan for patients infected with HCV genotypes 1 and 2 in 2015. However, little is yet known as to the efficacy and safety of this novel therapy in patients on maintenance haemodialysis (HD). The present report describes a preliminary experience in 10 patients (five males and five females) who underwent maintenance HD. All of them had HCV genotype 1b, without having the resistance-associated variants at Y93 or L31 in the nonstructural proteins 5A (NS5A) region...

BACKGROUND: Adolescence is a period of transition to adulthood. Little is known about oral mucosal lesions (OMLs) in teenagers, in which the emergence of new habits, unfamiliar to children, could affect the type of lesions. The aim of this study was to evaluate the distribution of oral mucosal lesions (OMLs) in a wide sample of adolescents. METHODS: A retrospective cross-sectional study was carried out examining all medical records of adolescents (aged 13-18 years) treated at the Dental Clinic of the University of Brescia (Italy) in the period from 2008 to 2014...

The term Mycoplasma pneumoniae-induced rash and mucositis (MIRM) was recently proposed to identify the mucocutaneous condition secondary to M. pneumoniae infection that had historically been regarded among the more confusing pathologies of erythema multiforme and Stevens-Johnson syndrome. Based on a number of previous reports, these syndromes require differentiation since they have different prognoses and specific treatment requirements. We report a case of oral and genital erosions that strongly resembled MIRM without rash but were found to be secondary to a Chlamydia pneumoniae infection...

Fuchs syndrome is a particular type of erythema multiforme major; the lesions are only found on the mucosae and specifically affect oral, ocular, and genital mucosae. The cause is not always immediately apparent, which is why this pathology requires a rigorous, detailed clinical examination to eliminate a differential diagnosis. The severity of the symptoms, particularly of oral and ocular symptoms, requires immediate treatment. The treatment of this pathology requires a multiple-drug regime. Through a clinical case study, the objective of this work is to help guide practitioners when diagnosing and treating this pathology as no current consensus exists on these 2 subjects...

AIM: From a pharmacokinetic viewpoint, ombitasvir/paritaprevir/ritonavir, one of the standards of care for genotype 1b chronic hepatitis C in Japan, could be possible in patients with impaired renal function. The aim of this study was to assess the efficacy and safety that have not yet been addressed in patients undergoing dialysis. METHODS: A retrospective, multicenter study evaluated the outcome of 12-week ombitasvir (NS5A inhibitor)/paritaprevir (NS3/4A protease inhibitor)/ritonavir combination therapy for dialysis patients...

Imatinib mesylate (imatinib) is a tyrosine kinase inhibitor initially approved by the US Food and Drug Administration in 2001 for chronic myeloid leukemia (CML). Since then, the number of indicated uses for imatinib has substantially increased. It is increasingly important that dermatologists recognize adverse cutaneous manifestations of imatinib and are aware of their management and outcomes to avoid unnecessarily discontinuing a potentially lifesaving medication. Adverse cutaneous manifestations in response to imat-inib are not infrequent and can include dry skin, alopecia, facial edema, and photosensitivity rash...

The terms 'lichenoid' and 'interface' dermatitis are often used interchangeably to describe an inflammatory pattern characterized histologically by damage to the basal keratinocytes in the epidermis. The mechanism of cell damage of such cells is now best understood as apoptosis, or programmed cell death. This inflammatory pattern of dermatoses, is also accompanied frequently by a band of lymphocytes and histiocytes in the superficial dermis, that often obscures the dermal-epidermal junction, hence the term 'lichenoid'...
