Article Synopsis
  • Peutz-Jeghers syndrome (PJS) is a rare genetic disorder linked to heightened cancer risk, primarily due to mutations in the STK11 gene, with a study focusing on its manifestations and genetic profiles among 20 patients across 14 families.
  • The research found that typical symptoms began around 18.9 years of age, with common issues including abdominal pain and specific polyps; 85% of patients had mucocutaneous lesions, and dysplastic polyps were present in some cases, leading to a few malignancies.

Background: Peutz-Jeghers syndrome (PJS) is characterized by the presence of hamartomatous polyps in the gastrointestinal tract and mucocutaneous pigmentation on the lips, oral mucosa, nose, fingers, and toes. Synchronous mucinous metaplasia and neoplasia of the female genital tract (SMMN-FGT) refers to the occurrence of multifocal mucinous lesions in at least two sites, including the cervix, uterus, fallopian tubes, and ovaries, in the female genital tract. SMMN-FGT and PJS are rare diseases with a very low incidence, especially when occurring simultaneously.

Department of Paediatric Surgery, SGPGIMS, Lucknow, 226014, India.

Background: Peutz-Jeghers syndrome (PJS) is an autosomal dominant disorder characterized by hamartomatous gastrointestinal polyps along with the characteristic mucocutaneous freckling. Multiple surgeries for recurrent intussusception in these children may lead to short bowel syndrome. Here we present our experience of management in such patients.
