1.Vasculitis.
2.Ecthyma Gangrenosum.
Classically described as occurring in Pseudomonas aeruginosa bacteraemia, but can be caused by other organisms. It also affects other immunocompromised patients as those with severe malnutrition, diabetes, etc. It starts as well-circumscribed oedematous lesions (vesicles) that quickly acquire a haemorrhagic centre and an erythematous periphery. Increase in size is associated with central ulcerative necrosis spreading towards the periphery of the lesion (Fig.1).
