Familial lymphohistiocytosis is one of a group of familial diseases recently reported, probably related to Letterer-Siwe disease. These illnesses are almost invariably fatal in early childhood and are characterized pathologically by diffuse infiltration of most tissues by lymphocytes and large histiocytes. This may be the first reported case of extreme ocular involvement by this pathologic process.
