title: "Colonic type" adenocarcinoma of the nasal cavity and paranasal sinuses.
abstract: Primary "colonic type" tumors of the nasal cavity and paranasal sinuses are adenocarcinomas with histologic features similar to those of colonic cancers. Their behavior is one of local invasion and recurrence. Unlike tumors of the colon, they rarely metastasize. Surgical resection by means of lateral rhinotomy with or without radiation is the treatment of choice. Prognosis is poor. This type of tumor should be recognized by pathologists and its implications should be known to head and neck surgeons.
