the peutz-jeghers syndrome is characterized by an association of gastrointestinal polyposis with rnelain spots on oral mucosa, lips, and skin. this symdrorne is inherited as a simple mendelian autosomal dominant trait. intussusception is by far the most common complication. although these polyps are widely regarded as hamartomas and rarely undergo malignant change, they have been reported to be...

Peutz-Jeghers syndrome is an autosomal dominant inherited disease, belonging to the hamartomatous polyposis syndromes. It is characterized by multiple hamartomatous polyps of the gastrointestinal tract associated with oral and anal mucocutaneous pigmentations. We report the case of an adult patient diagnosed with an atypical form of Peutz-Jeghers syndrome, thereby emphasizing the different poss...

A 46-year-old female presents with a pelvic mass and is diagnosed as having a high-grade endometrial stromal sarcoma. During surgery, she is noted to have areas of intussusception of the small bowel secondary to large hamartomatous polyps. The patient had a previous history of small bowel obstruction secondary to what had been thought to be hyperplastic polyps but represented hamartomatous poly...

  Hamartomatous polyps of the palatine tonsil are very rare. They have been variously termed as a lymphangiectatic fibrous polyp, lipoma, pedunculated tonsil etc. in the English literature. We present here a case of hamartomatous polyp of the tonsil occurring in a 32-year-old male who presented with bilateral enlarged palatine tonsils with recurrent tonsillitis. Surgical excision showed two pa...

Peutz-Jeghers syndrome is a rare condition characterized by mucocutaneous pigmentation, polyposis and an increased cancer risk at a number of gastrointestinal and extra intestinal organs. We present a patient with a history of gastrointestinal bleeding with no mucocutaneous pigmentation. Upper and lower gastrointestinal endoscopy revealed multiple polyps located in the deuodenum and colon. Hist...

Background Juvenile polyps, classified as hamartomatous lesions with neoplastic potential, are the most common gastrointestinal polyp of childhood. Risk factors for neoplasia include germline DNA mutations, a family history of juvenile polyps, and multiple polyps (≥3 or ≥5). Only a few large pediatric series (>100patients) of patients with juvenile polyps have been reported, with limited data a...

BACKGROUND Digestive hamartomatous polyps are a rare entity. They may be sporadic (solitary Peutz-Jeghers polyp or solitary juvenile polyp) or reveal genetic predisposition like Peutz-Jeghers syndrome, juvenile polyposis or Cowden disease. SUMMARY Diagnosis is based on personal and family history and on clinical data including physical signs (in particular dermatological), endoscopic findings...

Mutations in a protein phosphatase and a protein kinase cause hamartomatous polyposis syndromes, which are characterised by the formation of multiple benign polyps and an increased susceptibility to some types of cancer.

A case is reported here of juvenile polyposis in a 15year-old girl. She was diagnosed upon the assessment of the dysenteric syndrome. Coloscopy and gastroscopy had shown polyps of variable size whose histological study confirmed the hamartomatous character typical of the youthful non adenomatous polyps free of dysplasia. There was no localization in the small bowel. Coloprotectomy with ileoanal...

Cronkhite-Canada Syndrome (CCS) is a syndrome characterised by a constellation of signs including but not limited to onychodystrophy of the finger and toe nails, skin hyperpigmentation and alopecia. Endoscopic features showed hamartomatous polyps involving all segments of the gastrointestinal tract with the characteristic exception of being oesophageal sparring. These polyps show confirmation b...
