A variant myelodysplastic syndrome with multilineage Pelgeroid chromatin.
An unusual myelodysplastic syndrome with similar features in two patients is described. The entity is characterized by a maturation arrest at the myelocyte stage, strikingly clumpy chromatin, and a clinical course marked primarily by difficulties caused by anemia and thrombocytopenia. Electron microscopic description of the characteristic abnormal clumpy chromatin cells is included. While the disorder is unquestionably a myelodysplastic syndrome, it is clearly distinct from chronic myelogenous leukemia, chronic myelomonocytic leukemia, and the spectrum of refractory anemias with excess blasts.

Protein C antigen deficiency and warfarin necrosis.
Recent reports have suggested a correlation between congenital protein C deficiency and tissue necrosis complicating oral anticoagulants (warfarin necrosis). The authors studied blood samples of 13 patients, obtained two weeks to more than six months after warfarin necrosis. Protein C antigen levels were assayed by an enzyme-linked immunosorbent assay method (Diagnostica Stago, France). Factors II, VII, IX, and X were assayed by functional methods, and IX and X additionally by immunologic methods. The results show that 11 of 13 patients with a history of tissue necrosis had low protein C levels, ranging from 23 to 69%, with the normal range being 70-140%. These results confirm that low protein C antigen levels are implicated in the pathogenesis of warfarin necrosis.

Anti-Pr cold hemagglutination associated with livedo reticularis.
A report of anti-Pr cold hemagglutination associated with livedo reticularis is presented. Livedo reticularis is descriptive of the superficial venous system appearing when blood flow is altered in this area. Cold antibody directed against the Pr antigen of the red cell membrane can cause hemagglutination, thereby altering blood flow in cooler areas of the body. This patient had livedo reticularis approximately 8 months prior to detection of the anti-Pr cold agglutinin.

Acute leukemia after successful chemotherapy for oat cell carcinoma.
A report of acute myelomonocytic leukemia following successful therapy for oat cell carcinoma is presented. The patient had been treated with extensive cytotoxic and radiation therapy, and was without clinical evidence of disease at one year follow-up. Eighteen months later, a peripheral smear revealed numerous blasts with monocytoid characteristics. This unusual presentation is discussed and compared with several other cases appearing in the recent literature.
