DRESS syndrome with gall bladder granulomatousvasculitis: case report
A 63-year-old man developed DRESS syndrome with gallbladder granulomatous vasculitis during treatment withcarbamazepine.
The man received oral carbamazepine tablets 200mg twice aday for seizures. Five weeks later, he experienced atypicalchest pain. A maculopapular rash and significantly derangedliver function tests (LFT) were observed during his admission.A presumptive diagnosis of carbamazepine-related adversedrug reaction was made. He was advised to stopcarbamazepine and was prescribed levetiracetam. But hefailed to fill his prescription for levetiracetam and continued onhis old stock of carbamazepine on discharge. After 1 week, hedeveloped epigastric pain and altered LFT, fever and elevatedlipase which suggested acute pancreatitis. Abdominalultrasound showed an oedematous heterogeneous pancreasconsistent with pancreatitis. Also, there were multipleimmobile gallstones.
The man underwent a cholecystectomy and was discharged.Three weeks later, he presented again with raisedinflammatory markers, fever and delirium. A gall bladderhistology showed a granulomatous vasculitis without evidenceof cholecystitis. Carbamazepine concentration was measuredwhich confirmed his ongoing ingestion of the drug. His bloodcount revealed intermittently raised eosinophil count. Overthe next 2 weeks, he returned to his baseline and wasdischarged home. The remaining tablets were discarded.There was no further presentations related to vasculitis.
