Case 7 :
Question :
  A 3 month old boy having hepatosplenomegaly. What is the diagnosis?

Answer :
  Langerhans cell histiocytosis

Chest involvement in LCH could be lung parenchymal lesion, enlarged mediastinal lymph nodes, and osteolytic lesion of the bony thorax.

For the pulmonary lesion, two forms have been described, depending on early or late stage. In early stage, the lung shows small nodules (1-5 mm diameter) some of which may cavitate. The fibrosis and cyst formation (each cyst is usually less than 1 cm size) are noted in later stage. Both forms are much better seen with CT scan. The chest radiograph findings consist of reticular, nodular, reticulonodular patterns, and honeycombing.
