Concomitant presentation of acute myeloid leukemia with T-cell large granular lymphocytic leukemia.

T-cell large granular lymphocyte leukemia (T-LGL) also known as T-cell chronic lymphocytic leukemia is rare and comprises a small minority of all small lymphocytic leukemias. The concomitant presentation of T-LGL with acute myeloid leukemia (AML) has not been previously reported. We present an elderly gentleman with concomitant T-LGL and AML (non-M3) diagnosed by a combination of morphologic evaluation, immunophenotyping by flow cytometry, and T-cell gene rearrangement studies.

Metastatic retroperitoneal epithelioid angiomyolipoma.

Angiomyolipoma (AML) is a rare benign neoplasm that usually arises in the kidneys, but may rarely originate in sites such as the retroperitoneum, liver and bone. It is characterised by an intimate admixture of blood vessels, smooth muscle and fat. This multiphasic composition allows for its recognition on ultrasound and CT scan examination.

Pulmonary tumor thrombotic microangiopathy from metastatic gallbladder carcinoma: an unusual cause of severe pulmonary hypertension.

Pulmonary hypertension and cor pulmonale due to tumor emboli causing pulmonary tumor thrombotic microangiopathy (PTTM) is rare and extremely difficult diagnosis to make prior to death. Pulmonary hypertension due to metastatic tumor emboli should be included in the differential diagnosis of various causes of dyspnea in patients with a history of cancer or more common causes, including infection, thromboembolism, metastasis, adverse effects of drugs, and recurrent effusions. We describe a patient with gallbladder carcinoma who presented with progressive dyspnea and severe pulmonary hypertension.

Bortezomib and dexamethasone in previously untreated multiple myeloma associated with renal failure and reversal of renal failure.

Multiple myeloma (MM) associated with renal failure carries a worse prognosis when compared with MM without renal failure. Bortezomib, a reversible proteosome inhibitor, is a new drug indicated for the treatment of refractory or relapsed myeloma. Published data on the use of bortezomib in patients with myeloma and renal failure are few.

Palmar skin lesions reversed by propylthiouracil therapy.

Antithyroid thioureylene compounds such as propylthiouracil, methimazole, and thiamazole have been shown to have some beneficial effect in the treatment of plaque psoriasis in small clinical trials. An incidental finding is reported here on a patient with autoimmune polyendocrine syndrome type II who had dermatitis-like palmar skin lesions on the right palm, which was reversed with propylthiouracil therapy.

Thigh abscess due to Nocardia farcinica.

Nocardia farcinica is an uncommon cause of nocardiosis and usually infects immunocompromised individuals. We describe a patient with Hodgkin's disease and a thigh abscess due to N. farcinica.
