A 22-year-old make presents with the following. His father was recently diagnosed with colorectal adenocarcinoma. What could be the possible diagnosis?

Images show osteoma of the mandible, colonic polyps and epidermoid cyst respectively. Eponymous polyposis syndromes now recognized to belong to the general disorder of FAP include: - 1. Gardner's syndrome (colonic polyps, epidermal inclusion cysts, osteomas) 2. Turcot's syndrome (colonic polyps and brain tumours) Osteomas usually present as visible and palpable prominences in the skull, mandible, and tibia of individuals with FAP. They are viually always benign. Radiographs of the maxilla and mandible may reveal bone cysts, supernumerary and impacted molars, or congenitally absent teeth. Desmoid tumours can present in the retroperitoneum and abdominal wall of affected patients, usually after surgery. Surgical treatment of patients with FAP is directed at removal of all affected colonic and rectal mucosa
