    Summary

    Mastocytosis, a condition involving bone marrow and intestinal mast cells, can cause severe shock-like symptoms when triggered by substances like alcohol. This case highlights the direct activation of intestinal mast cells leading to these reactions.

    Area of Science:

    • Gastroenterology
    • Hematology
    • Immunology

    Background:

    • Mastocytosis is a rare disorder characterized by the abnormal accumulation of mast cells in various tissues.
    • Gastrointestinal involvement in mastocytosis can lead to diverse and often severe symptoms.

    Observation:

    • A patient presented with shock-like symptoms, including tachycardia, headache, and diarrhea, after ingesting alcohol, acetylsalicylic acid, or receiving contrast medium.
    • Provocation with alcohol led to immediate and severe gastrointestinal distress.

    Findings:

    • The patient was diagnosed with urticaria pigmentosa involving the bone marrow, hepatosplenomegaly, and confirmed intestinal mastocytosis via jejunal biopsy.
    • Histological confirmation of intestinal mast cells supported the diagnosis.

    Implications:

    • The observed symptoms are attributed to the direct activation of accumulated intestinal mast cells.
    • This case underscores the importance of considering mastocytosis in patients with unexplained gastrointestinal symptoms and systemic reactions.
    • Differential diagnosis from conditions like allergic gastroenteritis, sprue, and carcinoid syndrome is crucial.
