Familial histiocytic reticulosis (familial haemophagocytic reticulosis)

The clinical and pathological findings are recorded in two siblings who died in early infancy from familial histiocytic (;haemophagocytic') reticulosis. The nature of this condition is obscure but probably represents a primary histiocytosis. The only other family on record is that described by Farquhar and Claireaux (1952) and by Farquhar, Macgregor, and Richmond (1958).
