A 19-year old male Caucasian patient visited the emergency department of our hospital because of melena. He was previously healthy and used no medication but had noticed black stools one week before his visit. There had been no abdominal discomfort, nausea or vomiting. None of his family members had gastrointestinal diseases, and he used no alcohol, did not smoke or use elicit drugs. His occupation is unknown. On physical examination the abdomen was nontender and without palpable masses. Rectal examination revealed black stools. His weight was 62 kg. and his length 1,87 m. Laboratory tests showed an iron deficiency anemia with a hemoglobin concentration of 4.7 mmol/L (normal > 8,5 mmol/L) and a serum ferritin concentration of 4 μg/L (normal > 30 μg/L). Liver function tests, serum creatinine, albumin, CRP and glucose were all normal. Duodenoscopy showed a normal esophageal, gastric and duodenal mucosa without evidence of recent bleeding. A Meckel scan showed no evidence for a Meckel's diverticulum. A small bowel series however, demonstrated a large polyp in the proximal jejunum and possibly a smaller polyp in the distal jejunum (Figure ).\nAs this polyp was the probable cause of the patient's bleeding, a laparotomy with peroperative small bowel endoscopy was performed. Approximately 50 cm beyond Treitz' ligament, a multilobular, 40 mm large polyp was seen, which was subsequently surgically resected (Figure ). There were no other small bowel polyps; the suspected smaller polyp seen on the small bowel series was therefore most likely an artefact.\nPathologic examination of this polyp demonstrated a hamartomatous polyp with arborization of smooth muscle compatible with a PJP (Figure ). No signs of dysplasia were seen and the surrounding tissue had a normal histological appearance. Immunohistochemistry was negative for p53, focally positive for cyclin D1 and the basal parts of the cryps were positive for Ki67/MIB1.\nThe postoperative course has been unremarkable and no further gastrointestinal bleeding has occurred. Total colonoscopy did not show any additional polyps. A repeated, extensive family history, performed by a clinical genetics consultant, did not reveal clues (including pigmentation, nasal or gastrointestinal polyps or typical secondary tumors) to the occurrence of PJS in family members.
We report a case of a 37 year old man who admitted to our hospital with complaint of occasionally painless rectal bleeding since 8 years ago which had exacerbated with no history of weight loss, abdominal pain, loss of appetite or anal pain. He had no significant past medical history or significant family history of GI malignancy. In physical examination he did not had any pigmentation in mucocutaneous and any abnormal finding in abdomen and rectal examination.\nGastrointestinal endoscopy revealed multiple polyps located in the deuodenum and less than 100 polyps in colon with aggregation in left colon and sigmoid with pathology of juvenile polyposis.\nA barium enema he had mucosal lesions in keeping with polyps in sigmoid (). A laparotomy was performed and multiple giant polyps entire colon was found. Total abdominal proctocolectomy and J pouch ileoanal anastomosis and omentectomy was performed and a diverting ileostomy was inserted. Histopathological evaluations of the polyps revealed hamartomatous polyps in keeping with a diagnosis of Peutz Jeghers syndrome ().
