Acute generalized exanthematous pustulosis induced by hydroxychloroquine: a case with atypical clinical presentation

Abstract Acute generalized exanthematous pustulosis is a rare drug-induced eruption that is characterized by acute, nonfollicular sterile pustules on an erythematous and edematous base. The most frequently implicated drugs are beta-lactam antibiotics. Hydroxychloroquine has been widely used to treat dermatologic and rheumatologic diseases and has been reported as a rare cause of acute generalized exanthematous pustulosis. A 42-year-old female presented with pustular lesions on the skin surface with erythema, facial edema, and occasional atypical target-like lesions after 21 days of treatment with 200mg/day hydroxychloroquine for rheumatoid arthritis, diagnosed one month previously. We report a case with acute generalized exanthematous pustulosis induced by hydroxychloroquine and treated with dapsone and systemic corticosteroid.

Acute localized exanthematous pustulosis caused by cefoperazone and sodium sulbactam

Abstract Acute localized exanthematous pustulosis is a localized variant of acute generalized exanthematous pustulosis, which is characterized by the eruption of multiple scattered pustules following drug administration. A 72-year-old woman presented with multiple erythematous pustules on her face, which had appeared two days after using cefoperazone and sodium sulbactam. Histopathological findings showed subcorneal pustules and mixed inflammatory cell infiltration in the dermis. The pustules resolved within about two weeks after the patient discontinued the antibiotics. This report discusses the case of a woman with a cutaneous drug reaction consistent with acute localized exanthematous pustulosis that occurred after cefoperazone and sodium sulbactam were administered.

Acute generalized exanthematous pustulosis associated with spider bite

Abstract: Acute generalized exanthematous pustulosis (AGEP) is an acute febrile rash, usually induced by drugs, which recently has been linked to spider bite. We report a case of a male patient, 48 years old, with an erythematous rash accompanied by fever and small non-follicular pustules. He reported previous pain in the buttock with the onset of a necrotic plaque. The lesion was compatible with spider bite of the genus Loxosceles. According to the EuroSCAR group instrument, the patient scored +10 indicating definite diagnosis of AGEP. As the patient had a compatible lesion and had no other triggers of AGEP, in an Loxosceles endemic area, the AGEP would be associated with spider bite, as described in other publications.

Acute generalized exanthematous pustulosis x Von Zumbusch’s pustular psoriasis: A diagnostic challenge in a psoriatic patient

AbstractSevere cutaneous drug reactions include a wide spectrum of clinical manifestations ranging from mild morbilliform cutaneous rash, to severe forms of hypersensitivity. Special attention is given in this report to the acute generalized exanthematous pustulosis (AGEP), induced in 90% of cases by the use of systemic drugs, especially aminopenicillins and macrolides. The incidence of the disease is low, 1-5 cases per million patients / year. The main differential diagnosis is Von Zumbusch's Pustular Psoriasis. The prognosis is generally good and the disease self limited, after withdrawal of the triggering drug. In this report the authors describe a case of AGEP, triggered by ceftriaxone in a patient with psoriasis vulgaris.

Pustulosis exantemática generalizada aguda secundaria a hidroxicloroquina / Acute generalized exanthematous pustulosis secondary to hydroxychloroquine

La pustulosis exantemática generalizada aguda (PEGA) es una erupción cutánea severa de escasa frecuencia, caracterizada por la aparición de pústulas estériles no foliculares sobre una base eritemato-edematosa, asociada a fiebre y neutrofilia. La hidroxicloroquina (HCQ), una droga antimalárica ampliamente utilizada en enfermedades dermatológicas, ha sido asociada como una causa poco frecuente de PEGA. Presentamos un paciente de sexo femenino de 20 años de edad, que desarrolló PEGA secundaria a la ingesta de hidroxicloroquina.

Acute generalized exanthematous pustulosis (AGEP) is an uncommon severe skin rash characterized by the appearance of non-follicular sterile pustules on an erythematous background, associated with fever and neutrophilia. It ́s characterized by an acute onset and spontaneous resolution within 2 weeks. Hydroxychloroquine (HCQ), an antimalarial drug widely used in dermatological diseases, has been associated as a rare cause of PEGA. We present a 20 years old woman who developed AGEP secondary to HCQ.
