Peutz-Jeghers syndrome with osseous metaplasia of the intestinal polyps

Pathology International
T NaritaS Yokoyama


A case of Peutz-Jeghers syndrome (PJS) with osseous metaplasia in three of 15 hamartomatous polyps of the small intestine is reported. At 35 years of age, the patient was diagnosed as having PJS by cutaneous pigmentation around the mouth and polyposis of the stomach, duodenum and intestine. Fifty-two polys of the large intestine were resected, which were characteristic of those of PJS. Three of them showed adenomatous and carcinomatous changes, but there was no osseous metaplasia in any of the resected polyps. At age 40, he had surgery under the diagnosis of intestinal obstruction. There were 15 polyps in the resected jejunum. These polyps were also characteristic of those of PJS. Additionally, three of these polyps were accompanied by osseous metaplasia. Histologically, mature bone formation and calcification were found close to the hyperplastic glands in the submucosa or in the propriate muscle. Malignant transformation was not observed. Osseous metaplasia is extremely rare in benign polyps, and it has not been reported in hamartomatous polyps of PJS to date. The knowledge of this association may be helpful in the clinical diagnosis of this benign lesion in PJS.
