  • Title: Osteoporosis as the sole presentation of bone marrow mastocytosis.
    Author: Lidor C, Frisch B, Gazit D, Gepstein R, Hallel T, Mekori YA.
    Journal: J Bone Miner Res; 1990 Aug; 5(8):871-6. PubMed ID: 2239371.
    Abstract:
    Three (young) adults with severe generalized osteopenia and vertebral compression fractures were studied. Extensive clinical and laboratory investigations were not contributory. Undecalcified bone biopsies demonstrated multiple mast cell granulomas in the marrow in two patients and numerous mast cells diffusely distributed throughout the bone marrow in the third patient. Mast cells may serve as a pathogenic agent in osteoporosis. Therefore, we conclude that isolated skeletal mastocytosis without clinical evidence of mast cell mediator release should be sought in the evaluation of a patient with unexplained severe bone loss.
