Most forms are not considered classic cancers, but rather myeloproliferative neoplasms. A very rare and aggressive form, mast cell leukaemia, is cancerous.
There is currently no known cure for systemic forms. Treatment focuses on managing symptoms and preventing complications. Some cases of cutaneous mastocytosis in children may resolve over time.
Symptoms can be triggered by factors like temperature changes, friction on the skin, stress, certain medications (e.g., NSAIDs, opioids), and alcohol, which cause mast cells to release their contents.
Diagnosis involves a combination of clinical evaluation, blood tests (like serum tryptase), a skin biopsy for cutaneous forms, and often a bone marrow biopsy for suspected systemic disease.
