The patient is a 46 year old female being evaluated for bariatric surgery. During an endoscopy procedure, a raised, "yellowish" nodule (size not specified) was identified at the mid esophagus, 30 cm from the incisors (image 1). An endoscopic mucosal resection (EMR) was performed. Grossly the lesion was described as a 0.6 x 0.4 cm yellow-red, ulcerated and centrally loculated lesion (image 2). H&E images of the EMR specimen are provided in images 3, 4, 5 and 6. PASD staining is shown in images 7 and 8. Immunohistochemistry is shown for S100 is in image 9 and inhibin in image 10.
