Varicella pneumonia is a type of viral pneumonia. It is a common cause of multiple small round calcific lung lesions. Varicella-zoster virus most commonly causes self-limited benign disease (chickenpox) in children. However, in adults it tends to cause significant complications including varicella pneumonia. Varicella pneumonia is the most serious complication of disseminated varicella-zoster virus infection with mortality rates of 9-50%. More than 90% of cases of varicella-zoster virus pneumonia in adults occur in patients with lymphoma or compromised immune systems. Histologic features of varicella-zoster virus pneumonia are those of diffuse alveolar damage. With recovery from the initial disease, spherical nodules are seen, scattered randomly throughout the lung parenchyma.
