Penicillamine-induced Stevens Johnson Syndrome-toxic Epidermal Necrolysis (SJS-TEN) Overlap in an HIV-infected Patient with Wilson's Disease and Hepatitis B.

INTRODUCTION: Stevens-Johnson syndrome (SJS) and Toxic epidermal necrolysis (TEN) are severe adverse drug reactions characterized by widespread blistering and mucositis. Wilson's disease is a rare, autosomal recessive disorder that results in excessive copper accumulation in the body, where penicillamine is an effective treatment option for copper chelation. Penicillamineinduced SJS-TEN is a rare but potentially fatal adverse effect. There is increased susceptibility to SJS/TEN in HIV infection due to immunosuppression and chronic liver disease due to impaired hepatic function. OBJECTIVE: To diagnose and manage the occurrence of the rare severe adverse cutaneous drug reactions in the backdrop of immunosuppression and chronic liver disease. CASE REPORT: We are reporting penicillamine-induced SJS-TEN overlap in a 30-year-old male with Wilson's disease, HIV and Hepatitis B who was treated with intravenous immunoglobulins. The patient later developed neurotrophic ulcer in the right cornea as a delayed sequela. CONCLUSION: Our case report emphasizes that there is an increased predisposition to SJS/TEN in immunocompromised and chronic liver disease patients. Physicians should be well aware of the potential danger of SJS/TEN in this subset of patients, even while prescribing a relatively safer drug.
