Propylthiouracil induced ANCA vasculitis and Sweet syndrome

A 65-year-old lady presented to our clinic for a rash affecting her neck, arms and legs. It initially started as small skin colored papules affecting the neck and spreading to her arms and legs. Simultaneously she was also being reviewed by the respiratory physicians for worsening dyspnoea and a chest radiograph showing bilateral lymphadenopathy. Her past medical history includes hyperthyroidism for which she was taking propylthiouracil (PTU) and asthma for which she was taking montelukast and inhalers.
