Crystal storing histiocytosis (CSH) is a rare disorder characterized by the accumulation of crystalline material in the cytoplasm of histiocytes. Involvement of the central nervous system (CNS) with CSH is extremely rare. Herein, we report a case of crystal storing histiocytosis involving the CNS. Using immunohistochemistry and mass spectrometry we demonstrate that the disease resulted from an ...

Interstitial lung diseases (ILD) comprise a number of clinical conditions, including sarcoidosis, pulmonary fibrosis and pulmonary Langerhans’ cell histiocytosis (PLCH; histiocytosis X).
