 Abstract


Severe congenital neutropenia (SCN) is a primary immunodeficiency disease characterized by early onset of severe bacterial infection and persistent severe neutropenia. We describe an SCN patient with a history of recurrent infections. The clinical course was complicated by necrosis of the nasal cartilage due to mucormycosis. Molecular studies revealed a homozygous germline HAX1 mutation.
Fungal infections may lead to serious complications in immunodeficient patients. Recurrent and severe infections should alert physicians to possible immunodeficiency disease. Early diagnosis and appropriate treatment are the most important keys to preventing irreversible
organ damage.

Key words: Fungal infection. HAX1. Mucormycosis. Severe congenital neutropenia.
