A 58-year-old male presented with malaise, ocular discharge and ulceration of his oral mucosa and glans penis. His medical history lists atrial fibrillation and idiopathic pancreatitis. Approximately one week prior to presentation he experienced fatigue, diffuse myalgia and fever. Four days later, he developed redness of his sclerae, a sticky discharge in his eyes and a sore throat. His general practitioner started chloramphenicol eye drops. Since then, he developed swelling, ulceration and painful aphthous lesions of his oral mucosa and his glans penis. Two days later, an allergic reaction to chloramphenicol was suspected and his general practitioner discontinued the eye drops. Our patient was started on oral prednisolone and clemastine tablets, one day thereafter he was admitted to our hospital. There was no fever upon presentation. The patient stated that he did not have sexual relations outside his marriage.
