RESUMO
Peutz-Jeghers syndrome (PJS) is a rare autosomal dominant genetic condition characterized by the development of hamartoma-type intestinal polyposis and areas of skin pigmentation, among other signs. Additionally, the occurrence of solitary Peutz-Jeghers polyps is exceedingly rare. We present the case of a 50-year-old female with a medical history of hypothyroidism, chronic gastritis, and dyslipidemia, who presented with dyspeptic symptoms and occasional rectal bleeding. Endoscopic examination revealed a solitary hamartomatous polyp in the gastric body and other gastrointestinal abnormalities. The patient underwent treatment and is being monitored with regular endoscopic studies and evaluations for other potential neoplasms. This case underscores the importance of considering the syndrome as a potential differential diagnosis. It emphasizes the necessity of a multidisciplinary approach to managing and monitoring such cases, particularly the early detection of possible neoplasms.
