Fixed drug eruption (FDE) usually appears as a solitary/small number of pruritic, well circumscribed, erythematous--violaceous macules that evolve into oedematous plaques which typically resolve after the discontinuation of the offending drug, leaving residual hyperpigmentation. This eruption is considered pathognomonic of a drug-induced dermatosis and is triggered within a few minutes or up to...

Entecavir (Baraclude®, Bristol-Myers Squibb) is a potent and selective antiviral agent that has demonstrated efficacy in patients with chronic hepatitis B. The most frequent adverse events attributed to entecavir include increased alanine aminotransferase, upper respiratory tract infection, headache, abdominal pain, cough, pyrexia, fatigue, and diarrhea. Although quite a few randomized double-b...

A 34-year-old woman was diagnosed with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), most likelyrelated to a reaction to allopurinol.The patient presented with a 2-week history of a painful pruritic rash that started on her back and progressed to the rest of her body over a five-day period. The eruption started after several new drugs were started, including allopurinol for hyp...

Fixed drug eruption (FDE) is typically establishes as round or oval, sharply delineated erythematous edematous plaques. Essentially it a drug-induced cutaneous reaction that happens at the similar site with each exposure to specific medication. A extensive spectrum of drugs can occasionally give rise numerous contrary orofacial manifestations, predominantly dry mouth, taste disturbances, oral m...

Drug-induced cutaneous rashes, whether confined to the skin or part of a systemic disease, are characterised by a spectrum of inflammatory disease patterns that include perivascular dermatitis, nodular and diffuse dermatitis, vesiculobullous lesions, pustular eruptions, sclerodermoid reactions, vasculitis, folliculitis/perifolliculitis and panniculitis. While a single drug can elicit a range of...

Cutaneous adverse effects of imatinib mesylate (Glivec) are common and various types of skin eruptions have been reported. We report here a 57-year-old man who presented with lichen planus-like lesions on his extremities and palmoplantar hyperkeratosis due to the use of imatinib mesylate for chronic myeloid leukaemia. The skin lesions improved after discontinuation of imatinib mesylate but re-a...

IMPORTANCE Several chemotherapeutic agents have been reported to induce subacute cutaneous lupus erythematosus (SCLE). To our knowledge, this is the first report to date of SCLE induced by monotherapeutic gemcitabine hydrochloride and includes a comprehensive review of all published cases of chemotherapeutic drug-induced SCLE. OBSERVATIONS We describe a patient who developed a SCLE-like erupt...

Erythema multiforme (EM) is an uncommon, immune-mediated disorder that presents with cutaneous or mucosal lesions or both. In herpes simplex virus (HSV)-associated EM, the findings are thought to result from cell-mediated immune reaction against viral antigen-positive cells that contain the HSV DNA polymerase gene (pol). The target lesion, with concentric zones of color change, represents the c...
