Pristinamycin-induced toxic epidermal necrolysis: A case report.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are acute, life-threatening and rare severe cutaneous adverse reactions induced by drugs in most cases. The drugs most often reported to be implicated in inducing TEN/SJS are allopurinol, antibacterial sulfonamides, antiepileptic drugs and oxicam. Pristinamycin is an oral streptogramin antibiotic with bactericidal activity against Gram-positive bacteria that is rarely linked to TEN. Typically, this condition develops 4-28 days after drug exposure, Herein, we report a case of a 71-year-old female who developed TEN within 3 days of administration of pristinamycin and was managed successfully with supportive care, including intravenous fluids, pain control, prophylactic antibiotics and intravenous methylprednisolone. This case of rapidly developing SJS/TEN after administration of pristinamycin highlights the possibility that these complications can develop within only a few days following ingestion of drugs thought to be probably safe.
