A boy with Farber's lipogranulomatosis is reported. Excessive ceramide was revealed by thin‐layer chromatography of the extracts from the liver. Acid ceramidase activity of the liver was 31.5% of control with exogenous substrate and 33.3% without exogenous substrate. The histological appearance showed granulomatous lesions, composed of spindle or oval‐shaped storage cells and proliferation of the connective tissues, in the subcutaneous tissue of the lower lip, periarticular regions and the pericardium. Histo‐chemically the storage cells were revealed to contain lipid and polysaccharide. The foreign body granuloma formed by the surgical suture in the liver was surrounded by a large number of foamy cells. In gastrointestinal mucosa widespread erosion, disappearance of glands and abundant collagen fibers were noted. On electron microscopy, the spindle or oval shaped cells in the subcutis of the lip had intracytoplasmic inclusions containing granular or fibrillar materials and a smaller number of curvilinear structures, so called “Farber bodies”. Our case was a typical clinical and histopathological presentation of Farber's lipogranulomatosis. However, ceramidase activity was higher than in previous descriptions, and severe gastrointestinal lesions and the appearance of a large number of foamy cells around the foreign body granuloma have not been described previously.
