A genetic disorder in which polyps form in the intestine and dark spots appear on the mouth and fingers. Having Peutz-Jeghers syndrome increases the risk of developing gastrointestinal and many other types of cancer.

A hereditary disease caused by autosomal dominant mutations involving CHROMOSOME 19. It is characterized by the presence of INTESTINAL POLYPS, consistently in the JEJUNUM, and mucocutaneous pigmentation with MELANIN spots of the lips, buccal MUCOSA, and digits.

An inherited condition characterized by generalized hamartomatous multiple polyposis of the intestinal tract. Transmitted in an autosomal dominant fashion, Peutz-Jeghers syndrome consistently involves the jejunum and is associated with melanin spots of the lips, buccal mucosa, and fingers. This syndrome is associated with abnormalities of chromosome 19. Also known as Jeghers-Peutz syndrome and Peutz's syndrome.

Peutz-Jeghers syndrome (PJS) is characterized by the association of gastrointestinal (GI) polyposis, mucocutaneous pigmentation, and cancer predisposition. PJS-type hamartomatous polyps are most common in the small intestine (in order of prevalence: jejunum, ileum, and duodenum) but can also occur in the stomach, large bowel, and extraintestinal sites including the renal pelvis, bronchus, gall bladder, nasal passages, urinary bladder, and ureters. GI polyps can result in chronic bleeding, anemia, and recurrent obstruction and intussusception requiring repeated laparotomy and bowel resection. Mucocutaneous hyperpigmentation presents in childhood as dark blue to dark brown macules around the mouth, eyes, and nostrils, in the perianal area, and on the buccal mucosa. Hyperpigmented macules on the fingers are common. The macules may fade in puberty and adulthood. Recognition of the distinctive skin manifestations is important especially in individuals who have PJS as the result of a de novo pathogenic variant as these skin findings often predate GI signs and symptoms. Individuals with PJS are at increased risk for a wide variety of epithelial malignancies (colorectal, gastric, pancreatic, breast, and ovarian cancers). Females are at risk for sex cord tumors with annular tubules (SCTAT), a benign neoplasm of the ovaries, and adenoma malignum of the cervix, a rare aggressive cancer. Males occasionally develop large calcifying Sertoli cell tumors of the testes, which...

Peutz-Jeghers syndrome is an autosomal dominant disease with multiple hamartomatous polyps in the stomach, small bowel, and colon along with distinctive pigmented skin lesions.

Peutz-Jeghers syndrome (PJS) is an autosomal dominant inherited disorder characterized by intestinal hamartomatous polyps in association with a distinct pattern of skin and mucosal macular melanin deposition. Patients with Peutz-Jeghers syndrome have a 15-fold increased risk of developing intestinal cancer compared with the general...

Peutz-Jeghers syndrome (PJS) is an inherited condition that is associated with an increased risk of growths along the lining of the gastrointestinal tract (called hamartomatous polyps) and certain types of cancer. Most affected people also have characteristic dark blue to dark brown macules around the mouth, eyes, and nostrils; near the...

Peutz-Jeghers syndrome (PJS) is a rare, autosomal-dominant disorder characterized by hamartomatous polyposis caused by germline mutations in the STK11 (LKB1) gene. Mutations are found in about 93% of individuals and may be inherited in an autosomal-dominant manner or occur de novo. The defining features are mucocutaneous pigmentation and...
