Metastatic Bronchoalveolar Carcinoma Presenting as Chronic Esophageal Stricture.

We report a case of chronic esophageal stricture resulting from metastatic bronchoalveolar carcinoma in a patient without a prior diagnosis of malignancy. The diagnosis was made on pathologic examination of the resected specimen after esophagectomy. Further workup subsequently revealed additional sites of metastasis.

Vascular Calcification Slows But Does Not Regress After Kidney Transplantation.

Introduction: Medial arterial calcification is a common and progressive lesion in end-stage renal disease that is associated with poor cardiovascular outcomes. Whether this lesion can be arrested or reversed is unknown, and was examined retrospectively by measuring progression of breast arterial calcification before and after kidney transplantation.

Methods: Arterial calcification was measured on serial mammograms from patients with previous kidney transplantation and compared to measurements performed before transplantation or in patients on the active waitlist.

Warfarin Accelerates Medial Arterial Calcification in Humans.

Objective: Warfarin is associated with medial arterial calcification in humans, but the magnitude and specificity of this effect and the role of other risk factors are unknown. Using serial mammograms, progression of arterial calcification was compared in women receiving no anticoagulants, warfarin, or other anticoagulants, and before, during, and after warfarin use. Approach and Results: Warfarin users with mammograms were identified by computerized searches of medical records that included renal function and diabetes mellitus.
