Small intestinal hemangiomas are uncommon tumors that frequently present with gastrointestinal bleeding (GIB). Diagnosis, detection, and treatment can be challenging and may require surgical intervention. An 81-year-old female presented with melena. Video capsule endoscopy revealed active bleeding in the proximal jejunum and push enteroscopy identified a polypoid nodule with central umbilication. The patient underwent laparoscopic resection and jejunal submucosal hemangioma was detected. Submucosal hemangiomas are a rare cause of GIB. As the most common site of submucosal hemangiomas is the mid-jejunum, they are not easy to detect. Surgical intervention is usually required for a definitive diagnosis and definitive treatment., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Numan et al.)

Raoultella planticola osteomyelitis is rarely reported in the literature. The most likely source in our case is the oral microbiome secondary to the tooth extraction. Herein we present a case of Raoultella planticola osteomyelitis of the jaw that leads to the diagnosis of diffuse large B-cell lymphoma (DLBCL) of the jaw. A 75-year-old male with no significant medical history, presented to the emergency department with right upper jaw pain after he had a tooth extraction a week before his presentation. Computed tomography (CT) scan of the face showed concerns of right maxillary osteomyelitis with soft tissue swelling and prominent cervical lymph nodes. He underwent a bone biopsy of the maxilla and was started on intravenous ampicillin-sulbactam. His bone culture grew pan-sensitive Raoultella planticola. in addition to that, his bone biopsy revealed diffuse large B-cell lymphoma of the jaw. The patient underwent staging imaging, and he was found to have metastasis to the liver. He was started on chemotherapy and had a good response. In conclusion, Raoultella planticola osteomyelitis is extremely rare. The diagnosis of maxillary DLBCL can be a challenge. Fortunately, our patient had an infection at the same site that led to the diagnosis of DLBCL., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2019, Asif et al.)

Angioedema is an allergic reaction that usually involves the face and pharynx. Intestinal angioedema is a rare subtype that is typically linked to the use of angiotensin-converting enzymes inhibitors (ACEIs). Intestinal angioedema is challenging to diagnose, as it can mimic gastroenteritis or other inflammatory bowel conditions. Herein, we present a 34-year-old female who presented with recurrent episodes of abdominal pain. She underwent extensive workup for her abdominal pain and rash, and all was unrevealing except for high Immunoglobulin E (Ig E). Multiple imaging came back negative for any pathology. The allergy and immunology team evaluated the patient, and they believed her symptoms are likely caused by isolated intestinal angioedema with a histamine-related rash. She was started on high doses of antihistamines; her symptoms partially improved. Subsequently, she was started on a trial of omalizumab, which resulted in complete resolution of her symptoms. In conclusion, intestinal angioedema is a rare disease that should be suspected in cases of recurrent abdominal pain with negative workup, especially if the patient is taking ACEIs. Few cases were reported in the literature for patients on ACEI. In our case, the diagnosis was a challenge, as the patient was never on ACEI., Competing Interests: The authors have declared that no competing interests exist.

Renocolic fistula is a rare clinical finding that is most commonly iatrogenic after surgical intervention. Herein, we present a case of renocolic fistula secondary to xanthogranulomatous pyelonephritis (XGP) with a subtle presentation as anemia. A 40-year-old female was found to have a hemoglobin of 6.5 g/dL after presenting for worsening fatigue. A urinalysis was remarkable for numerous white blood cell (WBC), positive bacteria, and nitrite. As part of her anemia workup, an esophagogastroduodenoscopy (EGD) was done which was normal while a colonoscopy showed a fistula opening with surrounding nodularity close to the splenic flexure of the colon. A computed tomography (CT) scan of the abdomen and pelvis with contrast showed chronic left kidney pyelonephritis with multiple contiguous abscesses in the inferior left kidney in addition to a staghorn calculus concerning for XGP. The patient was started on antibiotics and underwent laparotomy with repair of the renocolic fistula, partial omentectomy, and left nephrectomy. She tolerated the surgery well and was discharged with a stable hemoglobin. XGP is a rare type of chronic pyelonephritis that is usually a result of chronic obstruction by an infected stone. Spontaneous renocolic fistulas are rare nowadays with the advancement in antibiotics and renal stones treatment., Competing Interests: The authors have declared that no competing interests exist.

Synchronous multiple primary lung cancer is a unique type of lung carcinomas that are diagnosed with more than two different pathological types in the same or different lung lobes. Isolated metastasis to the kidney is considered rare. Herein, we present a case of a 58-year-old male with a history of chronic obstructive pulmonary disease (COPD) and 40 pack-year of cigarette smoking, who was diagnosed with synchronous small cell lung cancer (SCLC) and squamous cell carcinoma (SCC) with isolated metastasis to the kidney. Isolated kidney metastasis from lung cancer is an infrequent finding; it should be considered when the patient is diagnosed with lung cancer. In the absence of disseminated disease and contraindications, nephrectomy is an option for treatment with chemotherapy or as a palliative measure if the patient is symptomatic., Competing Interests: The authors have declared that no competing interests exist.

Breast cancer is the most common cancer in women; it is well-known to metastasize to lymph nodes, lungs, liver, brain, and bones. However, luminal gastrointestinal metastasis is rare, especially to the appendix. Herein, we report a case where cancer metastasized to the ileum and appendix, causing acute appendicitis and small bowel obstruction. This is a 44-year-old female with a history of stage IV metastatic breast cancer to bones, lungs, and ovaries, presented with acute abdominal pain for one day. Her abdomen was soft, distended with generalized tenderness. Computed tomography (CT) of the abdomen and pelvis showed a partial small bowel obstruction and swollen appendix. After her symptoms worsened on conservative treatment, she was taken to the operating room where she was found to have a markedly dilated ileum with signs of acute appendicitis, so she underwent ileocecectomy, appendectomy, and lysis of adhesions. Pathology showed metastatic breast cancer in the appendix with findings consistent with acute appendicitis. She tolerated surgery well without complications. In conclusion, small intestinal and appendiceal metastases of breast cancer are very rare though they should be considered in the differential diagnosis in cancer patients presenting with acute abdominal pain., Competing Interests: The authors have declared that no competing interests exist.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors. Tumor thrombus formation in advanced HCC stages is common and usually involves the hepatic or portal veins. The formation of tumor thrombus is considered a poor prognostic factor. Herein, we report a rare case wherein the thrombus extended to the inferior vena cava (IVC) reaching the right atrium without affecting the hemodynamic status. This is a 59-year-old male who presented with melena. He was found to have grade 3 esophageal varices with findings suggestive of recent bleeding associated with a large amount of blood in the gastric body that required banding. Computed tomography (CT) of the abdomen and pelvis showed multiple liver masses with an intraluminal IVC mass extending from the hepatic vein into the right atrium. A CT scan of the chest confirmed the presence of a tumor thrombus in the IVC extending to the right atrium. The patient declines surgical intervention and he was discharged. Unfortunately, he passed after a short period of time. In conclusion, tumor thrombus formation is common in HCC. However, expansion of the thrombus to IVC and right atrium is rare and indicates poor prognosis., Competing Interests: The authors have declared that no competing interests exist.

Anemia is a common finding in alcoholics. It is often multifactorial and caused by a combination of liver dysfunction, ineffective erythropoiesis, and poor nutrition. Zieve's syndrome (ZS) is a clinical syndrome that presents with a triad of jaundice, hemolytic anemia, and hyperlipidemia secondary to alcohol use. Herein, we present a case of a 58-year-old male with a history of liver cirrhosis who presented after a fall due to binge drinking and was found to have severe anemia. Workup was consistent with hemolytic anemia with no source of active bleeding. The patient was managed with supportive treatment and blood transfusions which improved his anemia. However, given his advanced liver disease, he developed encephalopathy and subsequently severe aspiration pneumonia. He died 18 days after admission., Competing Interests: The authors have declared that no competing interests exist.
