Superficial Thrombophlebitis of the Penis following AstraZeneca ChAdOx1-S Vaccination: A Rare Venous Thromboembolic Complication

Penile Mondor’s disease is a rare condition characterised by superficial thrombophlebitis of the penis which is usually self-limiting. The cause is often unknown. The AstraZeneca ChAdOx1-S vaccine has been found to cause a hypercoagulable state, which is well documented. This case report describes a man who presented with Mondor’s disease following ChAdOx1-S vaccination with no other risk factors. LEARNING POINTS: This is the first documented case of penile thrombophlebitis following ChAdOx1-S vaccination. We highlight a rare presentation of an uncommon condition. Clinicians should be aware of the clotting risks associated with ChAdOx1-S vaccination.
