Subcutaneous panniculitis-like T-cell lymphoma in a patient with long-term remission with standard chemotherapy.

Subcutaneous panniculitis-like T-cell lymphoma (SPTL) is a very rare postthymic T-cell non-Hodgkin's lymphoma with poor prognosis. There is not a standard treatment for this disease. Here we describe the first case of SPTL with unusual periorbital involvement, pancytopenia, hepatic dysfunction and coagulopathy, which was successfully treated with a chemotherapy regimen of cyclophosphamide, hydroxydaunomycin (doxorubicin), Oncovin (vincristine) and prednisone (CHOP).

[The registration of false teeth and the others].

Retinal vein thrombosis as the presenting symptom of essential thrombocythemia.

Visual loss resulting from retinal vascular disorders can be the presenting sign of serious systemic disease. Associations between retinal vein thrombosis and other systemic disorders have been well documented, but a comprehensive literature search failed to reveal any report of essential thrombocythemia as a cause of central retinal vein thrombosis. We describe the first young female patient with symptomatic visual loss due to central retinal vein thrombosis as her presenting symptom of essential thrombocythemia.

Acquired von Willebrand disease in a patient with monoclonal gammopathy of undetermined significance.

We describe a patient with acquired von Willebrand disease (vWD), who had typical presentation and clinical manifestations of acquired vWD, but correct diagnosis was delayed because of lack of awareness and early recognition. The patient was initially seen at a community hospital with persistent nasal mucosal bleeding and was transfused with an excessive amount of cryoprecipitates before appropriate hemostatic evaluation. Hemostasis work-up revealed that he had classic features of acquired vWD.
