[Co-existence of fibrous bone dysplasia and familial intestinal polyposis]. / Koexistenz von fibröser Knochendysplasie und familiärer intestinaler Polyposis.

The aetiology of fibrous bone dysplasia is unknown. Combinations with endocrine and non-endocrine diseases are recognised. The co-existence of polyostotic fibrous dysplasia with Peutz-Jeghers syndrome has not been previously described. A patient is now reported who had both these diseases. They have in common a benign proliferative tendency in various organs, but the common denominator is unknown. The basic relationship between the conditions requires further observation and study.
