Systemic mast cell disease (SMCD) can be regarded as a tumorous proliferation of tissue mast cells involving various organs. The frequency with which SMCD is found in patients with haematological disorders suggests that the association is non-random. The association includes primarily, myeloid disorders such as myelodysplastic syndromes and acute or chronic myeloproliferative disorders. Lymphoproliferative disorders may also occur but more rarely, mostly non-Hodgkin's low grade B cell lymphomas. In this report a case is described in which SMCD occurred in a patient with hairy cell leukaemia.

Systemic mastocytosis is a rare condition characterized clinically by the local consequences of vasoactive peptides released from infiltrating mast cells in the reticuloendothelial tissues. Mast cells originate from the pluripotent bone marrow stem cells; it is therefore not surprising that myeloproliferative and myelodysplastic disorders commonly coexist or terminate the clinical phase of mastocytosis. We report here, to our knowledge, the first case of Hodgkin's and Castleman's disease occurring in a patient with co-existent systemic mastocytosis, which remained unchanged after combination chemotherapy for Hodgkin's disease.

Systemic mast cell disease is characterized by an abnormal infiltration of mast cells involving several parenchymal organs and the bone marrow. Its spectrum of clinical and histologic presentation is highly variable and is not necessarily correlated with prognosis. Mast cell disorders presenting as atypical infiltrates in the bone marrow may simulate or be associated with other hematolymphoid malignancies, from which they must be distinguished. The paucity of reliable histochemical and immunohistochemical markers for the detection of mast cells in paraffin sections further confounds this diagnosis. The authors have employed immunohistochemistry for the C-KIT encoded tyrosine kinase receptor protein, CD117, for detection of mast cells on paraffin sections of 89 bone marrow specimens including systemic mast cell disease and other disorders. CD117 staining was found in all cases of mast cell disorders (seven of seven), and in one case of chronic myelogenous leukemia in blast crisis. None of the other myeloid disorders tested (0 of 16), or any of the cases of Hodgkin's disease (0 of 12), B-cell lymphomas (0 of 32), T-cell lymphomas (0 of 3), or histiocytic proliferations (0 of 3) showed staining for CD117. CD117 expression is effective in the separation of mast cell disease from disorders that may simulate it histologically.

Systemic mastocytosis is a disease characterized by multifocal mast cell proliferation in the bone marrow or other extracutaneous organs. Because of loosely scattered and hypo-/agranular mast cells, the diagnosis is sometimes very difficult. In the bone marrow, mast cell infiltration may be associated with prominent lymphoid infiltration leading to a misdiagnosis of a low grade non-Hodgkin lymphoma. A 49-year-old woman presented with right arm and leg pain, psychiatric symptoms, and diarrhea for four years. Physical examination and laboratory investigation revealed hepatosplenomegaly, anemia, mild thrombocytosis, mild leucocytosis and lymphocytosis. In the bone marrow biopsy, there was a prominent B lymphocyte proliferation reminiscent of a low grade non-Hodgkin lymphoma/leukemia and there were some spindle cells aggregates in paratrabecular location. The consecutive bone marrow biopsies were similar to the first. The subsequent splenectomy specimen exhibited striking fibrosis. In the lymph node sections, there was marginal zone hyperplasia. Multifocal accumulations of mast cells were strongly positive with mast cell tryptase and CD117 on immunohistochemical staining, though no metachromasia was identified in Giemsa and Toluidine Blue stained aspirates and tissue sections, probably due to hypo-/agranulation of mast cells. The case was presented to emphasize the importance of the antibody to mast cell tryptase in the diagnosis of mastocytosis and to discuss problems of differential diagnosis of systemic mastocytosis.

Systemic mastocytosis with associated clonal hematologic non-mast cell lineage disease (SM-AHN) represents a specific subtype of mastocytosis and is extremely rare in children. We describe a 4-year-old child with systemic mastocytosis associated with Hodgkin's lymphoma. The child had cutaneous mastocytosis and lymphadenopathy without other clinical features of SM, which was diagnosed only by bone marrow examination.
