[Gardner's syndrome, a rare disease]. / Gardner-syndroma, avagy amikor a raritások "kopogtatnak az ajtón".

Introduction: Gardner's syndrome is a clinical subgroup of Familial Adenomatosus Polyposis, arare, autosomal disease. It is characterized by gastrointestinal polyps and extra-intestinal manifestations including multiple osteomas, skin and tissue tumours. The authors describe a case of a male patient, and discuss the diagnosis, treatment and follow-up of patients with Gardner's syndrome. We conclude that the knowledge of rare syndromes is very important for the correct treatment.
