Purpose of study: Immune-mediated adverse drug reactions occur commonly in clinical practice and include mild, self-limited cutaneous eruptions, IgE-mediated hypersensitivity, and severe cutaneous adverse drug reactions (SCAR). SCARs represent an uncommon but potentially life-threatening form of delayed T cell-mediated reaction. The spectrum of illness ranges from acute generalized. Pityriasis rosea (PR) is an acute, self-limited, exanthematous skin disease characterized by the appearance of slightly inflammatory, oval, papulosquamous lesions on the trunk and proximal areas of the extremities (picture 1A-E). The diagnosis and management of this disorder are reviewed here Exanthematous Diseases of Childhood Several viral and bacterial illnesses may be accompanied by localized or generalized skin eruptions called exanthems. These eruptions may be the first manifestation of a disorder and often are the reason for parents and patients to pursue medical evaluation An exanthem is the most common type of cutaneous drug eruption. The terms maculopapular and morbilliform (measles-like) are also often used to describe this class of drug rash. The eruption is characterized by pruritic, red to salmon-colored macules or papules that at times coalesce into plaques (Fig. 159-1) The most common IC-induced delayed reactions are self-limited exanthematous eruptions that develop within 1 week of exposure
Cell-mediated delayed-type exanthematous reactions rarely occur on NSAIDs. NSAIDs relatively frequently cause fixed drug eruptions. Skin lesions that occur after administration of X-ray contrast media are usually self-limited and generally resolve spontaneously within three to seven days Pityriasis rosea. Pityriasis rosea (PR) is an acute, self-limited, exanthematous skin disease characterized by the appearance of slightly inflammatory, oval, papulosquamous lesions on the trunk and proximal areas of the extremities ( picture 1A-E ). The diagnosis and management of this disorder are reviewed here Cutaneous reactions appear to be self-limited but may be treated with topical corticosteroids, oral antihistamines, and/or pain-relieving medications. Patients may develop cutaneous reactions after the first dose, second dose, or both doses of an mRNA COVID-19 vaccine. Reactions to the second dose tend to be less severe and develop faster The most common IC-induced delayed reactions are self-limited exanthematous eruptions that develop within 1 week of exposure. Risk factors for delayed reactions to IC include atopy, contrast exposure during high pollen season, use of the agent iodixanol, a history of other cutaneous drug eruptions, elevated serum creatinine levels, and.
Drug eruptions can range from a mild, simple exanthematous eruption to severe eruptions with systemic involvement, such as toxic epidermal necrolysis. The image above shows a widespread exanthematous eruption. This can be localized to skin or, in the presence of fever, may be part of a systemic reaction The pustular eruption typically lasts for 7-10 days and is followed by superficial desquamation lasting several days, characterized at times by collarettes of scale (Fig. 26.3). In most cases, AGEP is self-limited and resolves without treatment 1-2 weeks after removing the offending drug. Courses lasting longer than 2 weeks are rare Cutaneous drug eruptions are a major health concern and may affect up to 1 % of patients taking systemic medications, and are seen in 2-3 % of hospitalized patients. Most reactions are mild and self-limited upon discontinuation of the medication, but severe and life-threatening reactions are also possible
AGEP commonly presents with leukocytosis and fever in the acute pustular phase and follows a self-limited desquamative recovery phase upon removal of offending drug. Severe cases of AGEP may have. Acute generalized exanthematous pustulosis (AGEP) is a severe cutaneous adverse reaction (SCAR) characterized by sterile non-follicular pustules on an erythematous base that form rapidly after drug exposure. AGEP is mediated by numerous cytokines produced by drug specific T-cells that mediate neutro Bullous or blistering drug eruptions and drug-induced anaphylaxis and hypersensitivity syndromes are among the most serious types of adverse drug reactions. Based on the various mechanisms, bullous drug eruptions may be classified into the following categories: Spongiotic or eczematous Acute generalized exanthematous pustulosis Fixed drug eru.. The onset of a morbilliform eruption (MDE; also known as exanthematous or maculopapular drug eruption) typically occurs within 7 to 10 days after the initiation of the culprit drug. Occasionally a 14-day window has been noted. On rechallenge with a drug that the patient has been sensitized to in the past, the eruption may occur within 24 hours
Synopsis. Exanthematous, or morbilliform, eruptions are the most common of all medication-induced eruptions. They consist of red blanching macules and papules that begin on the head and trunk and spread symmetrically caudally and to the proximal extremities. In severe eruptions, lesions coalesce and may lead to generalized erythroderma Also if inflammatory, or other morbid affections, supervene upon the pure disease, they may become subjects for medical treatment. With these exceptions, hooping cough appears to be a self-limited disease. Most of the class of diseases usually denominated eruptive fevers, are self-limited Acute generalized exanthematous pustulosis (AGEP) usually appears abruptly. There is a sudden onset of high fever (usually above 38°C) and a rash. Initially the eruption consists of widespread erythematous and edematous plaques. Within hours to days, numerous tiny, nonfollicular subcorneal pustules appear within the plaques (Figure 1 and. Acute Generalized Exanthematous Pustulosis (AGEP) is a rare drug reaction manifesting as pustular lesions with surrounding erythema following exposure. The disease is often self-limited and treatment is supportive. It may present in an atypical variant with vesicles that desquamate into erosions, which classifies the disease as an AGEP/SJS Overlap

Exanthematous (or morbilliform) drug eruptions, although often extremely pruritic, are usually benign and self-limited. They may be difficult to distinguish from a viral exanthem. Some are the result of a drug-virus interaction such as occurs when amoxicillin or ampicillin is administered to patients with an Epstein-Barr virus infection Drug eruptions are among the most common diseases of the skin. The majority of cases are benign and self-limited, however particular variants are very severe and potentially life threatening. A precise and rapid diagnosis is essential but can be difficult in some instances as drug eruptions may lack specific histological criteria. Furthermore, pitfalls in the diagnosis are frequent and. Drug eruptions are among the most common diseases of the skin. The majority of cases are benign and self-limited, however particular variants are very severe and potentially life threatening. A precise and rapid diagnosis is essential but can be difﬁcult in some instances as drug eruptions may lack speciﬁc histological criteria. Furthermore
Multiple pustular eruptions are present on patients. Answer: C Acute generalized exanthematous pustulosis (AGEP) is a rare adverse skin reaction usually caused by medication or acute infection The mild exanthematous inflammatory disease is characterized by the presence of salmon-coloured maculopapular lesions. The most striking feature is the arrangement of the lesions such that the long axis is parallel to the lines of cleavage. The eruption is usually generalized, affecting chiefly the trunk, and the course is often self-limited Background Acute generalized exanthematous pustulosis (AGEP) is a relatively rare exfoliative dermatosis consisting of a generalized eruption of sterile, nonfollicular pustules arising on widespread erythematous and edematous skin that is usually caused by drugs. It has an acute onset, and patients often have systemic manifestations, including leukocytosis, fever, and hemodynamic instability The most common cutaneous manifestations of M. pneumoniae infection, exanthematous or maculopapular eruption, may be either localized or confluent. These eruptions are self-limited, and no therapy for the cutaneous eruption is needed. Erythema nodosum is a reaction pattern caused by a variety of infections, including M. pneumoniae
. It begins with a solitary red to tan plaque (herald plaque), usually on the trunk, arms, or thighs, which is followed by similar but smaller papular or macular lesions; these later may peel and leave a scaly collarette Bullous or blistering drug eruptions and drug-induced anaphylaxis and hypersensitivity syndromes are among the most serious types of adverse drug reactions. Based on the various mechanisms, bullous drug eruptions may be classified into the following categories: Spongiotic or eczematous Acute generalized exanthematous pustulosis Fixed drug eru.. Exanthematous eruptions in children are more likely to be due to a viral infection than another infection; however, most such reactions in adults are due to medications. Note any concurrent infections, metabolic disorders, or immunocompromise (eg, due to HIV infection, cancer, chemotherapy) because these increase the risk of drug eruptions
The eruption was always psoriasiform and either limited to the palms and soles (case 3) or extensive, with erythroderma (case 1) and acute generalized exanthematous pustulosis (case 2). Seven previous published cases were also psoriasiform and self-limited, 2 and 2 other cases 3 , 4 of severe cutaneous hypersensitivity were reported Severe cutaneous adverse reaction (SCAR) is life-threatening. It consists of Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP), and generalized bullous fixed drug eruptions (GBFDE). In the past years, emerging studies have provided better understandings regarding the. Acute generalized exanthematous pustulosis (AGEP) is a rare severe cutaneous adverse reaction caused mostly by drugs. Three of 22 AGEP cases (13.6%), recruited by us as part of two prospective multinational studies, occurred 24 to 48 hours after a spider bite. We suggest that a spider bite is a possible trigger for AGEP Fixed drug eruption (FDE) is a drug reaction that classically occurs in the same location with every re-administration of a particular drug (also see the Fixed Drug Eruption chapter). FDEs are relatively common in children, accounting for 10-14 % of ADRs. It may be very difficult to determine the causative drug
The MPE phenotype consists of self-limited diffuse erythematous macules and papules without systemic involvement . DRESS syndrome, meanwhile, is characterized by cutaneous involvement with typical skin eruptions (e.g., exfoliative dermatitis and generalized maculopapular exanthema), fever, atypical lymphocytosis, eosinophilia, lymphadenopathy. The eruption commonly begins with a Pityriasis rosea is a self-limited, exanthematous skin disease that develops acutely and is characterized by the appearance of slightly inflammatory, oval, papulosquamous lesions on the trunk and proximal areas of the extremities. Pityriasis rosea is largely a disease of older children and young adults Background: Little is known about the dermoscopic evaluation of cutaneous adverse drug reactions (CADRs). Objectives: To evaluate the dermoscopic patterns of CADRs and identify those associated with severe cutaneous adverse reactions to drugs (SCARDs). Patients and Methods: Patients included in this study from May 2015 to April 2016 had presented with CADRs
Exanthematous (or morbilliform) drug eruptions, although often extremely pruritic, are usually benign and self-limited. They may be difficult to distinguish from a viral exanthem. They may be difficult to distinguish from a viral exanthem Pityriasis rosea is a self-limited, exanthematous disease that manifests as oval papulosquamous lesions typically distributed in a symmetrical fashion over the trunk and extremities. The exact etiology is unclear, but viral triggers have been suggested. The eruption is usually preceded by a primary lesion consisting of a slightly raised, salmon. This skin lesions may be associated by viral agents, usually developed in children and adulthood and self limited.

Acute, febrile, exanthematous disease of children (age 2-5, males, Asian) Self-limited vasculitis with a predilection for coronary arteries Cause unknown possibly an immune response to bacterial infection, since it occurs in outbreak , Exanthematous drug eruptions, also known as maculopapular drug eruptions, are the most common cutaneous skin reactions and represent approximately 95% of all cutaneous drug eruptions. Exanthematous drug eruptions usually begin within 1-2 weeks of starting a medication and gradually resolve 1-2 weeks following cessation Drug Eruptions • Medication-induced changes in the skin & mucous membrane, most are hypersensitivity reactions • Most cutaneous drug reactions are self-limited . if offending drug is discontinued • Triggers: Antigen from foods, insect bites, drugs, environmental, exercise-induced, & infections Pathophysiolog
Therapy for exanthematous drug eruptions is supportive in nature. First-generation antihistamines are used 24 h/d. Other treatments include long term antibiotics, oral antifungal agents, phototherapy, acitretin, methotrexate and hydroxychloroquine.
