In this case report, we describe two patients with systemic mastocytosis with an associated haematological neoplasm. The KIT c.2447A>T;p. (Asp816Val) (D816V) mutation, the original driver mutation of mastocytosis, can, in combination with additional genetic abnormalities, drive the clonal evolution towards an additional myelodysplastic or myeloproliferative neoplasia. When patients present with a dominant phenotype of the latter neoplasia, which is often the cause in chronic myelomonocytic leukaemia (CMML) or acute myeloid leukaemia (AML), the original mastocytosis could be overlooked, missing therapeutic opportunities.

We present the case of a 58-year-old male patient with a long-standing, intermittent oedema of the lower extremities and significant spontaneous variations in haematocrit values. Repeated examinations failed to reveal a clear etiology until the patient suffered from a severely painful exacerbation of leg oedema and hypotension. Laboratory analysis showed hypoalbuminemia. The combination of oedema, hypotension, hypoalbuminemia and hemoconcentration was indicative of a systemic capillary leak syndrome. This condition is known to be associated with monoclonal gammopathy, as was the case in our patient. New investigations showed suspicious lesions in the nasopharynx, scrotum and breast. Biopsies of this breast mass as well as bone marrow biopsy showed the presence of an extranodal natural killer/T-cell lymphoma, nasal type. Polychemotherapy was administered according to the SMILE schedule leading to a remission after two cycles. The patient then underwent autologous hematopoietic stem cell transplantation. The patient is currently without signs of systemic capillary leak syndrome. This report illustrates that systemic capillary leak syndrome may occur as a prodrome of haematological malignancies, such as natural killer/T-cell lymphoma and documents that it is responsive to chemotherapy.
