Abstract:

A female patient, 16-year-old, presented ??recurrent lower abdominal pain for one year, recurrence and aggravation for 10 days''. Physical examination revealed that the patient's lips had dot-like dark spots, 1?4 mm in diameter, with clear boundaries and without fusion and fading under pressure, and there was tenderness in the upper left abdomen. The laboratory and imaging examinations were further completed and the patient was admitted to hospital with ??1. intussusception; 2. multiple polyps in the intestine; 3. likely Peutz-Jeghers syndrome (PJS)''. After admission, laparotomy was performed for duodenal and jejunal polyp resection, and the postoperative diagnosis was PJS. PJS is a clinically rare disease with three typical characteristics: skin and mucous membrane pigmentation, multiple polyps in the gastrointestinal tract, and family genetic tendency. The clinical data of this case are introduced to improve the understanding of PJS, provide reference for the following diagnosis and treatment of similar patients, and reduce the occurrence of emergency surgery and short bowel syndrome.

Key words: Peutz-Jeghers syndrome (PJS), intussusception, familial adenomatous polyposis
