A 22-year-old male patient was admitted in the surgery ward with symptoms of bowel obstruction. He had a history of vomiting and abdominal distention since 10 days. The patient had experienced similar complaints on and off for the past year. On examination, the patient's abdomen was distended and a vague swelling was noted in the umbilical region. The baseline investigations were normal with only a rise noted in the patient's erythrocyte sedimentation rate which was 70 mm at 30 minutes and 118 mm at the end of 1hour. His Mantoux tested negative. An X-ray abdomen showed multiple fluid levels and a contrast-enhanced CT scan revealed ileal wall thickening and mesenteric nodes. The surgeon proceeded with a laparotomy and resected a segment of ileum with omental adhesions and sent for histopathological examination.\nThe cut open small intestinal segment measured 34 × 6 cm. A polyp of 1.5 cm diameter was noted 18 cm from the proximal end. Two ulcers were identified, the first measuring 2 × 2.5 cm was 14 cm from the proximal end and the second, measuring 2 × 1.5 cm was 20cm from the proximal end. Both ulcers were shallow, situated along the horizontal plane, with undermined edges and a fibrotic base. A stricture was present 9cm from the distal end with dilatation of the proximal segment. The serosa showed large lymph nodes measuring 4 × 5 cm, whose cut section was whitish and creamy in consistency. The areas adjacent to the ulcers showed diffuse thickening of the wall and on cut section revealed a whitish mass extending from the submucosa upto the serosa. Representative sections from each of the grossly abnormal areas and the resected margins were submitted for processing.\nSections from the polyp showed a polypoidal mass with a core containing smooth muscle fibers and was identified as a Peutz-Jeghers polyp. Sections from the ulcerated areas showed edematous lamina propria with a dense infiltration of eosinophils and lymphocytes with congested blood vessels in the submucosa and a dense lymphocytic infiltration in the muscularis propria [] and serosa. Sections from the lymph node showed partial loss of architecture, areas of necrosis and fibrosis with epithelioid cell aggregates but no definite granuloma was made out. Multiple sections from the thickened areas showed diffuse sheets of lymphocytes ulcerating the mucosa and infiltrating transmurally upto the serosa and periserosal fat. Rest of the mucosa showed focal erosions, increased eosinophilic and lymphocytic infiltrates in the lamina propria and increased intra-epithelial lymphocytes with focal shortening of villi. In view of the high suspicion of tuberculosis and lymphoma, further diagnostic modalities were sought after such as acid fast staining, polymerase chain reaction (PCR) and immunohistochemistry.\nZiehl–Neilson acid fast staining revealed numerous acid fast bacilli. The PCR was positive for tubercle bacilli. A lymphoma panel of immunohistochemical markers showed CD 45 and CD 20 positivity [] with weak positivity for Bcl2. The rest of the IHC markers such as cytokeratin, chromogranin, CD 3 and CD 10 were negative.\nThus, a final diagnosis of primary small intestinal B-cell lymphoma, tuberculosis and Peutz-Jeghers polyp was made.
A 22-year-old male patient was referred to us for evaluation of multiple pigmented lesions over his mouth, present since childhood. Since the age of 9 year, there was a history of occasional hematochezia. However, there was no history of melena. The parents had taken him to a local physician, and the condition was managed with antihelminthic drugs, but the problem used to recur. There was no history of weight loss or any other systemic complaints. Five days back, he had presented to the general emergency with complaints of nonpassage of stool and flatus, pain, and distension of abdomen and vomiting. He had tachycardia, tachypnea, dehydration, hypotension, and distended rigid abdomen. Per rectal examination revealed empty rectum with blood mixed mucus. Straight X-ray abdomen showed dilated bowel loops, multiple air-fluid levels, and the absence of gas in colon and rectum []. Diagnosis of small bowel obstruction was made, and the patient was resuscitated. Hematological profiles and serum electrolytes were within the normal limits. Exploratory laparotomy was done. On exploration, ileocecal intussusception was found with a short segment of gangrenous ileum which was managed with limited ileocecal resection []. Numerous polyps were found along the whole length of the small and large gut. Proximal ileostomy with distal mucous fistula was made. A polyp was found to be the apex of the intussusception, which was histologically found to be a hamartomatous polyp [].\nDuring follow-up, upper gastrointestinal endoscopy and colonoscopy were done which revealed the presence of polyps from the gastric fundus to the rectum. Biopsy from those polyps confirmed a hamartomatous pathology []. Besides, detailed cutaneous examination revealed melanotic mucocutaneous macules in the lips and buccal mucosa [Figures and ]. As per the patient, one of his two younger brothers had similar lesions over the lips, but he was not available for examination. There was no history of hematochezia, melena, or weight loss among the siblings or any other family member.\nAfter 5 months of the first surgery, the patient was reoperated for taking down of ileostoma. During operation, colocolic intussusception was found in the transverse colon with a large mass palpable inside. This colocolic intussusception was resected with ileotransverse anastomosis. Postoperative period was uneventful, and the patient was discharged after 6 days. Histopathology of the mass showed expansion of the marginal zone of the lymphoid tissue along with sheets of heterogeneous population of small lymphocytes, suggestive of MALToma []. Immunohistochemistry showed CD20 positivity. Both proximal and distal margins were negative for malignant cells.\nAfter 1-year follow-up, the patient was asymptomatic. Colonoscopy revealed few pedunculated polyps in the rectum and sigmoid colon, but the surface was smooth. Yearly colonoscopy follow-up was planned to detect early malignant changes.
