• diffuse alveolar damage
  4 June 2004

  Digital case
  JRC:6304 : Diffuse alveolar damage (methotuxate).
  JRC:6305 : Diffuse alveolar damage.
  Definition: Diffuse alveolar damage (DAD) is the lesion that underlies and is responsible for the majority of cases of the acute respiratory distress syndrome (ARDS).
  DAD can follow a large number of precipitating events including infection, sepsis, trauma, shock, toxic inhalants, drug toxicity, burns and others.
  DAD begins with an acute exudative phase characterized by the presence of (...)

• pulmonary adenocarcinoma
  13 November 2003

  pulmonary adenocarcinomas
  Definition: Adenocarcinoma is the most common type of lung cancer in contemporary series, accounting for approximately one-half of lung cancer cases (about 50%).
  The increased incidence of adenocarcinoma is thought to be due to the introduction of low-tar filter cigarettes in the 1960s, although such causality is unproven.
