The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
The SCARs group of disorders includes four other drug-induced skin reactions: drug reaction with eosinophilia and systemic symptoms (DRESS syndrome), Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and Stevens–Johnson/toxic epidermal necrolysis overlap syndrome (SJS/TEN). SJS, SJS/TEN, and TEN, while initially described as ...
About 90% of these adverse reactions take the form of benign morbilliform rash hypersensitivity drug reactions such as MPR. However, they also include more serious reactions: Pseudo-allergic reactions in which a drug directly stimulates mast cells, basophils, and/or eosinophils to release pro-allergic mediators (e.g. histamine);

Allopurinol has been linked to severe cutaneous adverse reactions (SCAR), toxic epidermal necrolysis, Stevens-Johnson syndrome, and drug reaction with eosinophilia and systemic symptoms (DRESS). Clinically, these syndromes are similar in that they both involve fever, eosinophilia, rash, and dysfunction of the liver and kidneys. [1]
[3] [4] Risk factors include HIV/AIDS and systemic lupus erythematosus. [2] Diagnosis is based on a skin biopsy and involvement of more than 30% of the skin. [3] TEN is a type of severe cutaneous adverse reactions (SCARs), together with SJS, a SJS/TEN, and drug reaction with eosinophilia and systemic symptoms. [5]
The typical amount of time it takes for a rash to appear after exposure to a drug can help categorize the type of reaction. For example, Acute generalized exanthematous pustulosis usually occurs within 4 days of starting the culprit drug. Drug Reaction with Eosinophilia and Systemic Symptoms usually occurs between 15 and 40 days after exposure.
A wide range of drugs are known to cause hypereosinophilia or eosinophilia accompanied by an array of allergic symptoms. Rarely, these reactions are severe causing, for example, the drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome. Drug- induced hepatitis marked by immunoallergic pathology, which has much bidirectional ...
