What is acute generalized Exanthematous Pustulosis?

What causes acute generalized Exanthematous Pustulosis?
Acute generalized exanthematous pustulosis (AGEP) is a severe cutaneous reaction characterized by the appearance of edematous erythema with overlying non-follicular pinpoint pustules; approximately 90% of AGEP cases are caused by drugs such as anti-malarial agents, anti-infective agents, and diltiazem [37R].
What drugs cause Exanthematous Pustulosis?
Although many causative factors leading to AGEP have been described, it is, in over 90% of cases, associated with the ingestion of drugs [5,6]. Aminopenicillins, pristinamycin, sulphonamides, quinolones, hydroxychloroquine, terbinafin and diltiazem are the most frequent causative drugs [7].
How do you get rid of acute generalized Exanthematous Pustulosis?
Acute generalized exanthematous pustulosis (AGEP) is most commonly caused by antibiotics (eg, aminopenicillins, macrolides, cephalosporins) followed by calcium channel blockers. The main treatment of AGEP is discontinuation of the culprit medication, which typically results in resolution within 2 weeks.

Is there an overlap between acute generalized exanthematous pustulosis and toxic epidermal necrolysis?
Background: Both acute generalized exanthematous pustulosis (AGEP) and toxic epidermal necrolysis (TEN) are adverse cutaneous reactions. Despite the fact that these 2 cutaneous reactions differ in presentation, prognosis, pathologic features, and treatment, overlap can exist between them, creating a diagnostic challenge.
What is acute generalized exanthematous pustulosis (AGEP)?

What are the most severe cutaneous manifestations of epidermal necrolysis?
The most severe cutaneous manifestations include pustular and bullous skin eruptions. These 2 manifestations can lead to acute generalized exanthematous pustulosis or Stevens-Johnson syndrome and toxic epidermal necrolysis.
