ABSTRACT

Mastocytosis is carachterized by excessive mast cell accumulation in the skin and/or internal organs. Mastocytosis is divided into two groups; systemic and cutaneous. Symptoms depend on excessive cytokine release and their local and systemic affects. Symptoms may be mild or cause life-threatening anaphylactic reactions. In the literature anaphylactic reactions reported in systemic disease of adult and childhood mastocytosis. We here present an anaphylaxis in the newborn with a diagnosis of cutaneous mastocytosis.
