Reacción de hipersensibilidad tardía asociada a la picadura de medusa

Abstract

A case is presented involving a patient who sought medical attention due to the appearance of inflammatory skin lesions 10 days after a jellyfish sting. The symptoms progressed to severe bronchospasm, and respiratory failure, necessitating orotracheal intubation and management in the intensive care unit (ICU), considering a delayed hypersensitivity reaction. Initiation of steroid pulses was deemed necessary, leading to progressive improvement, subsequent liberation from invasive ventilatory support, and discharge from the intensive care unit. Despite the low frequency of appearance, the severity of these reactions that can put the patient's life at risk makes it necessary to know their pathophysiology and management.
