A case report: Anaphylactic reaction to chloroprocaine in a patient with mastocytosis and lidocaine allergy

Abstract

This case report presents a 53-year-old woman with a history of mastocytosis and reported lidocaine allergy who experienced an anaphylactic reaction following administration of chloroprocaine during a breast biopsy procedure. The patient was promptly treated with epinephrine, methylprednisolone, famotidine, and diphenhydramine, leading to stabilization. She was subsequently transferred to the intensive care unit (ICU) for observation and discharged after 24 hours. This case highlights the importance of vigilance and preparedness for managing anaphylactic reactions in patients with mastocytosis and known allergies to local anesthetics.
