Review Case ReportsSweet's syndrome as the presenting symptom of hairy cell leukemia with concomitant infection by Mycobacterium kansasii.
A patient with Sweet's syndrome and leukopenia is reported. Hematological evaluation revealed hairy cell leukemia (HCL). The clinical picture was dominated by persistent fever, which is a common feature of both Sweet's syndrome and HCL. ⋯ Remarkably, the skin lesions completely regressed within 1 week after the start of r-IFN-alpha. In the literature, Sweet's syndrome is rarely mentioned as a feature of HCL. Mycobacterial disease, especially atypical mycobacteria, is relatively often seen in HCL.

Incidence and clinical risk factors for bleeding and thrombotic complications in myeloproliferative disorders. A retrospective analysis of 260 patients.
Bleeding and thrombosis are frequent complications in myeloproliferative disorders (MPD) and are associated with severe organ damage and a high mortality. Elevated platelet count, elevated hematocrit, and patient age are regarded as risk factors for bleeding and thromboembolic events in MPD, although the significance of these parameters was not confirmed by clinical studies. We retrospectively analyzed vascular complications in 260 patients with MPD and tried to identify parameters predictive for bleeding and thrombembolic events. ⋯ Thrombohemorrhagic complications were less frequent after phlebotomy in PV and after therapy with alkylating agents in CML. The institution of cytoreductive therapy soon after the diagnosis was made may explain the reduced incidence of complications later in the disease. We conclude that morbidity and mortality from thrombohemorrhagic complications are high in myeloproliferative disorders.(ABSTRACT TRUNCATED AT 400 WORDS)
