Hypovitaminosis D in Haematological Malignancies: Cause or Consequence?

Vitamin D is a pleiotropic hormone, widely controversial for its role in the development of chronic diseases and cancers, including haematological malignancies, and also for its impact on overall survival. Observational and interventional studies are being conducted on hypovitaminosis D and haematological malignancies and their subtypes in order to improve the therapeutic management of patients. We carried out a prospective observational study over three years on a population of 251 patients followed up for newly diagnosed haematological malignancies to investigate the impact of vitamin D deficiency on this category of patients.

Bronchopulmonary sequestration is a rare malformation characterized by lung tissue fed by one or several aberrant systemic arteries. The authors present the case of a 35-year-old woman in whom extralobar sequestration was fortuitously detected at the time of persistent pleuropneumopathy. Computed tomography was used in the diagnosis of pulmonary sequestration.
