A 24-year-old Caucasian man presented with an acute onset of melaena to the Emergency Department of our hospital. He had no abdominal pain, or history of change in bowel habit or any significant loss of weight or appetite. He was previously healthy and took no regular medications. He had no family history of gastrointestinal disorders. Our patient was also a non-smoker and had no history of illicit drug use.\nUpon admission, he was hypotensive and tachycardic. However, abdominal examination was completely unremarkable. Rectal examination revealed black tarry stool. Multiple dark pigmented patches were noted on the buccal mucosa of our patient. Laboratory tests revealed microcytic, hypochromic anaemia with a haemoglobin of 7.6 gm%. Blood urea was elevated at 12 mmol/litre. Initial assessment showed no other abnormalities.\nHe was resuscitated and required transfusion of six units of blood. Urgent upper gastrointestinal endoscopy revealed polyps in the stomach and duodenum, but no active bleeding sites were found. The presence of buccal pigmentation and multiple polyps on endoscopy suggested a diagnosis of PJS. A computed tomography (CT) scan of the abdomen of our patient was therefore performed. This confirmed multiple small bowel intussusceptions. (Figure )\nUrgent laparotomy was undertaken on our patient and the intussusceptions were reduced. Through enterotomies, eight polyps were removed from the affected segment of the gut. The affected segment of gut was found to be viable. He had a fairly uneventful recovery with no further bleeding. Pathological examination of the polyps confirmed hamartomas with smooth muscle arborisation, compatible with Peutz Jeghers polyps. No features of pseudo-invasion were noticed in any of the polyps.

In 2003, a 40-year-old woman consulted a doctor because of feeling a palpable mass in the right breast and bleeding discharge from both breasts. Mammography was taken and revealed bilateral mass with infiltrating margins. Excisional biopsy was performed on both breasts. In histopatholgical examination, grossly; the right side showed a nonencapsulated mass with 5.0 × 4.0 × 1.0 cm size as well as relatively dense consistency and the left one showed the same mass with 6.0 × 3.0 × 2.0 cm size. In microscopic examination it was showed carcinoma in atypical sclerosing papilloma of both breasts [].\nOne month later bilateral modified radical mastectomy and axillary lymph nodes dissection were performed. In microscopic examination there was no residual of primary tumor and the only abnormality is atypical ductal hyperplasia. Lymph-nodes, skin, and nipple were free. Three months later a colonoscopy was performed and multiple polyps were found in the large bowel. Biopsy was taken and the result was hamartomatous polyp [].\nTwo years later in 2005, she was referred to the hospital again because of abnormal uterine bleeding (menometrorrhagia). Pelvic ultrasound showed increased endometrial thickness with normal adnexal regions. Bilateral salpingo-oophorectomy was performed. In histopathological examination, grossly, the uterus was measured 10.0 × 8.0 × 3.0 cm. The right ovary was measured 4.0 × 2.0 × 1.0 cm and the left one 4.0 × 3.0 × 1.0 cm. The cut surface of both ovaries showed nonhomogenous appearance with no obvious lesion. In microscopic examination, both ovaries showed sharply circumscribed rounded epithelial nests composed of ring-shaped tubules encircling the hyalinized basement membrane-like material. The nests have two basic patterns: The simple pattern is that of a single tubule encircling a central rounded hyaline mass, and the complex pattern is characterized by communicating tubules encircling multiple hyaline masses. These features are compatible with sex cord tumor with annular tubules that are usually associated with Peutz–Jeghers syndrome []. Except simple hyperplasia of endometrium; no any pathologic feature was found in the endometrium.
