ABSTRACT
Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic and intra-abdominal lymphadenopathy. A diagnostic bronchoscopy was performed where an incidental tracheal nodule was discovered and biopsied. Pathology was consistent with epithelial-myoepithelial carcinoma. Lymph node biopsy demonstrated non-caseating granulomas consistent with sarcoidosis. Patient underwent tracheal resection of the primary tumor with primary tracheal reconstruction. Hypercalcemia subsequently normalized with clinical improvement. Repeat CT imaging demonstrated complete resolution of lymphadenopathy. Our findings are suggestive of a possible paraneoplastic sarcoid-like reaction to the epithelial-myoepithelial carcinoma with associated lymphadenopathy and symptomatic hypercalcemia.
ABSTRACT
Sporadic Creutzfeldt-Jakob disease is a rare neurodegenerative disorder of unknown etiology that causes rapidly progressive dementia. This disease is uniformly fatal and most patients die within 12 months. Clinical findings include myoclonus, visual disturbances, and cerebellar and pyramidal/extrapyramidal signs in addition to rapidly progressive cognitive and functional impairment. These findings are all non-specific and it is often difficult and challenging to diagnose premortem because of low awareness and clinical suspicion. We present a 66-year-old woman with a 5-month history of rapidly progressive dementia. After a series of extensive diagnostic examinations and continuous follow-up, she was diagnosed with probable sporadic Creutzfeldt-Jakob disease based on Centers for Disease Control and Prevention (CDC) criteria, with key findings of rapidly progressive dementia, blurry vision, extrapyramidal signs (cogwheel rigidity), and abnormal hyperintensity signals on diffusion-weighted MRI. Her symptoms progressively worsened and she died 7 months after the onset. The postmortem brain autopsy demonstrated the presence of abnormal protease-resistant prion protein by Western Blot analysis. A literature review was performed on differential diagnoses that present with rapidly progressive dementia and thereby mimic sporadic Creutzfeldt-Jakob disease. These include Alzheimer's disease, dementia with Lewy Bodies, frontotemporal dementia, meningoencephalitis, corticobasal degeneration, progressive supranuclear palsy, CADASIL, and paraneoplastic encephalomyelitis.

Minimally invasive surgery for resection of colon tumors is being utilized with increasing frequency making accurate preoperative tumor localization essential to proper surgical planning and patient positioning. Traditional endoscopic localization techniques such as lesion distancing from the anal verge are adequate in the majority of patients. Patients with a significantly tortuous and redundant colon, however, are at increased risk for ambiguous and incorrect lesion localization. The use of endoscopic submucosal marking by injection to tattoo the site of interest may increase the accuracy of tumor localization, but its efficacy can be technique dependent. We present a novel technique for endoscopic tumor localization using endoscopic clip placement, followed by immediate abdominal radiograph, to accurately locate a colonic lesion in preparation for laparoscopic colonic resection.

A 50-year-old woman presented with chronic epigastric abdominal pain and constipation. She underwent diagnostic upper and lower endoscopy for further evaluation. Several hours following the procedure, she developed chest and subcutaneous emphysema of her upper chest, neck, and face. A chest X-ray demonstrated marked subcutaneous emphysema, pneumopericardium, and pneumomediastinum. A CT scan revealed a small leak at the rectosigmoid junction. Because the patient did not have peritoneal signs, she was treated conservatively and discharged on hospital day seven. The complications of both esohagogastroduodenoscoy, and colonoscopy are discussed, with an emphasis on perforations.

Suspected cases of acute appendicitis in pregnancy are considered surgical emergencies due to the potentially devastating outcomes for both mother and unborn child if the appendix perforates. Acute appendicitis is also the number one cause of non-traumatic acute abdomen in pregnancy, as well as the number one cause of fetal death. We present a case report with a typical presentation of suspected acute appendicitis in a pregnant woman. The work up and diagnostic tools available are discussed at length, as well as the finer points in treatment of this population.
