Ceroidosis in the "brown bowel syndrome".
A middle-aged patient with "brown bowel syndrome" or gastrointestinal ceroidosis manifested as malabsorption of undetermined cause is described. Autopsy revealed involvement of the entire gastrointestinal tract and unusual cardiac findings. Microscopically, the pigment responsible for the discoloration is a lipofuchsin that is deposited in the smooth muscle cells of the gastrointestinal tract. In all reported cases, ceroidosis was associated with some abnormality of the gastrointestinal tract--that is, malabsorption, steatorrhea, or gross local disease--with the possible exception of prolonged malnutrition. This case is also unusual because of the unexplained multifocal proliferative endocarditis. Vitamin E deficiency may be the common denominator of all these various disorders.
