Isotretinoin and the risk of erythema multiforme Final SPC and PL wording agreed by the PhVWP in June 2010 Doc. Ref.: CMDh/PhVWP/021/2010 Rev 1 July 2010 SUMMARY OF PRODUCT CHARACTERISTICS Section 4.4 There have been post-marketing reports of severe skin reactions (e.g. erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)) associated with isotretinoin use. As these events may be difficult to distinguish from other skin reactions that may occur (see section 4.8), patients should be advised of the signs and symptoms and monitored closely for severe skin reactions. If a severe skin reaction is suspected, isotretinoin treatment should be discontinued. Section 4.8 Skin and subcutaneous tissues Cheilitis, dermatitis, dry skin, localised exfoliation, pruritus, rash disorders: erythematous, skin fragility (risk of frictional trauma) Very common (≥ 1/10) Rare (≥ 1/10 000,< 1/1000) Alopecia Acne fulminans, acne aggravated (acne flare), erythema (facial), exanthema, hair disorders, hirsutism, nail dystrophy, paronychia, Very Rare (≤ 1/10 000) photosensitivity reaction, pyogenic granuloma, skin hyperpigmentation, sweating increased, ∗ Erythema multiforme, Stevens-Johnson Syndrome, toxic Unknown epidermal necrolysis. PACKAGE LEAFLET Possible side effects Skin and hair problems Unknown frequency Serious skin rashes (erythema multiforme, Stevens- Johnson syndrome, and toxic epidermal necrolysis), which are potentially life-threatening and require immediate medical attention. These appear initially as circular patches often with central blisters usually on arms and hands or legs and feet, more severe rashes may include blistering of the chest and back. Additional symptoms such as infection of the eye (conjunctivitis) or ulcers of the mouth, throat or nose may occur. Severe forms of rash may progress to widespread peeling of the skin which can be life threatening. These serious skin rashes are often preceded by headache, fever, body aches (flu-like symptoms). If you develop a rash or these skin symptoms, stop taking Roaccutane and contact your doctor immediately. ∗ cannot be estimated from the available data Isotretinoin and the risk of erythema multiforme July 2010 Page 1/1` .

Less than three months later, the World Health Organization (WHO) declared coronavirus disease-19 (COVID-19) to be a global pandemic. Growing numbers of clinical, histopathological, and molecular findings were subsequently reported, among which a particular interest in skin manifestations during the course of the disease was evinced. Today, about one year after the development of the first major infectious foci in Italy, various large case series of patients with COVID-19-related skin Citation: Cazzato, G.; Foti, C.; manifestations have focused on skin specimens.

Fundamentals of Dermatology Describing Rashes and Lesions
Dermatology for the Non-Dermatologist May 30 – June 3, 2018 - 1 - Fundamentals of Dermatology Describing Rashes and Lesions History remains ESSENTIAL to establish diagnosis – duration, treatments, prior history of skin conditions, drug use, systemic illness, etc., etc. Historical characteristics of lesions and rashes are also key elements of the description. Painful vs. painless? Pruritic? Burning sensation? Key descriptive elements – 1- definition and morphology of the lesion, 2- location and the extent of the disease. DEFINITIONS: Atrophy: Thinning of the epidermis and/or dermis causing a shiny appearance or fine wrinkling and/or depression of the skin (common causes: steroids, sudden weight gain, “stretch marks”) Bulla: Circumscribed superficial collection of fluid below or within the epidermis > 5mm (if <5mm vesicle), may be formed by the coalescence of vesicles (blister) Burrow: A linear, “threadlike” elevation of the skin, typically a few millimeters long. (scabies) Comedo: A plugged sebaceous follicle, such as closed (whitehead) & open comedones (blackhead) in acne Crust: Dried residue of serum, blood or pus (scab) Cyst: A circumscribed, usually slightly compressible, round, walled lesion, below the epidermis, may be filled with fluid or semi-solid material (sebaceous cyst, cystic acne) Dermatitis: nonspecific term for inflammation of the skin (many possible causes); may be a specific condition, e.g. atopic dermatitis Eczema: a generic term for acute or chronic inflammatory conditions of the skin.

Erythema Multiforme: Recognition and Management Kathryn P
Erythema Multiforme: Recognition and Management Kathryn P. Trayes, MD; Gillian Love, MD; and James S. Studdiford, MD Thomas Jefferson University Hospital, Philadelphia, Pennsylvania Erythema multiforme is an immune-mediated reaction that involves the skin and sometimes the mucosa. Classically described as target-like, the erythema multiforme lesions can be isolated, recur- rent, or persistent. Most commonly, the lesions of erythema multiforme present symmetrically on the extremities (especially on extensor surfaces) and spread centripetally. Infections, especially herpes simplex virus and Mycoplasma pneumoniae, and medications constitute most of the causes of erythema multiforme; immunizations and autoimmune diseases have also been linked to erythema multiforme. Erythema multiforme can be differentiated from urticaria by the duration of individual lesions. Ery- thema multiforme lesions are typically fixed for a minimum of seven days, whereas individual urticarial lesions often resolve within one day. Erythema multiforme can be confused with the more serious con- dition, Stevens-Johnson syndrome; however, Stevens-Johnson syndrome usually contains widespread erythematous or purpuric macules with blisters. The management of erythema multiforme involves symptomatic treatment with topical steroids or antihistamines and treating the underlying etiology, if known. Recurrent erythema multiforme associated with the herpes simplex virus should be treated with prophylactic antiviral therapy. Severe mucosal erythema multiforme can require hospitalization

“Drug Induced Erythema Multiforme” – a Review Dr
European Journal of Molecular & Clinical Medicine ISSN 2515-8260 Volume 07, Issue 10, 2020 “Drug Induced Erythema Multiforme” – A Review Dr. Sudakshina Mukherjee, Dr. N. Aravindha Babu., Dr. L.Malathy, Dr. N.Anitha Post graduate student. Department of Oral pathology and Microbiology Sree Balaji Dental College and Hospital and Research Bharath Institute of Higher Education and Research ABSTRACT: Erythema Multiforme (EM) is an uncommon, acute inflammatory reactive mucocutaneous disorder. It's a hypersensitivity reaction to different antigenic stimuli, most common being infection followed by drugs. It occurs predominantly in younger age group. Recurrence in EM can be seen especially secondary to HSV infection. Erythema multiforme is manifested clinically as classical cutaneous target like lesions and mucosal bullae or erosions. Within the total affected patients 70% of them suffer from mucosal involvement though mucosal involvement separately is comparatively rare. Manifestations of EM can be varying and may pose a diagnostic dilemma because infections (particularly herpes simplex and mycoplasma pneumoniae) and drugs seem to predispose towards development of EM. KEYWORDS: erythema multiforme, Stevens and Johnson, target lesion, bilateral conjunctivitis INTRODUCTION: Bateman and Bulkley in the year of 1817 first recognized EM, But in the year 1846, the first American case “Herpes Iris.” was reported. Later, in 1866 under the term “erythema exsudativum multiforme” first characteristic morphological feature of this particular eruptions was described by Hebra[1] along with its cause which was due to internal or systemic origin and not for any local etiology [2]. Stevens and Johnson, [3] in 1922, reported EM with predominant involvement of the oral and conjunctival mucous membranes as “a new eruptive fever associated with stomatitis and ophthalmia.” On systemic drug administration severe reactions are manifested which characterizes like EM, and Steven Johnson syndrome.

Erythema Multiforme-Like Targetoid Lesions in Secondary Syphilis
Letters to the Editor 381 Erythema Multiforme-like Targetoid Lesions in Secondary Syphilis Yoon Young Kim, Ji Hyun Lee, Sun Yeong Yoon, Jeong Deuk Lee and Sang Hyun Cho* Department of Dermatology, Our Lady of Mercy Hospital, College of Medicine, The Catholic University of Korea, 665 Bupyung-Dong, Bupyung-Gu, Inchon, 403-720, Korea. *E-mail: [email protected] Accepted December 21, 2006. Sir, Syphilis has variable clinical courses, diverse manifes- tations and histological patterns, commonly mimicking those of other diseases, which were recognized long before Sir William Osler dubbed syphilis “the great imi- tator” (1). We report here erythema multiforme (EM)-like targetoid lesions in secondary syphilis. CASE REPORT A 37-year-old woman presented with a 6 week history of pruritic targetoid lesions, which were violaceous, erythematous plaques in an annular pattern, 1–2 cm in size, on both palms (Fig. 1). She had no prior history of medication or herpes simplex infection before the skin lesions occurred. All other physical findings were normal. The clinical findings suggested EM. Fig. 2. Skin biopsy performed on the palm was consistent with interface Skin biopsy performed on the palm was consistent dermatitis, and showed hyperkeratosis, lymphocytic exocytosis, and with interface dermatitis, and showed hyperkeratosis, vacuolization of the basal layer. A mild perivascular lymphohistiocytic lymphocytic exocytosis, and vacuolization of the basal infiltrate without plasma cells was present throughout the papillary dermis layer. A mild perivascular lymphohistiocytic infiltrate (HE; original magnification ×100). without plasma cells was present throughout the papil- lary dermis (Fig. 2). Proliferation of endothelial cells targetoid skin lesions, polymerase chain reaction (PCR) and a perivascular dermal infiltrate containing plasma technology was used to detect treponemal genomic cells, which are histological hallmarks of syphilis (2), DNA in the skin lesions.
