Cecal Tuberculosis Mimicking Submucosal Tumor.

Ileal Vanek's tumor mimicking cecal carcinoma.

Inflammatory fibroid polyps or Vanek's tumors are rare benign pseudotumoral lesions with morphological characteristics similar to those of submucosal mesenchymal tumors. They have been described in the gastrointestinal tract, most frequently in the gastric antrum. We present a case of ileal Vanek's tumor associated with a raised carcinoembryonic antigen level and with radiological and endoscop...

Multidrug-Resistant Tuberculous Mediastinal Lymphadenitis, with an Esophagomediastinal Fistula, Mimicking an Esophageal Submucosal Tumor

Mediastinal tuberculous lymphadenitis rarely mimics esophageal submucosal tumor, particularly in the case of multidrug-resistant tuberculosis (MDR-TB). Herein, we report the case of a 61-year-old woman who visited a local hospital complaining of odynophagia. An initial esophagogastroduodenoscopy revealed an esophageal submucosal tumor, and subsequent chest computed tomography showed subcarinal ...

Cecal Giant Lipoma Mimicking Malignancy

Incidental giardiasis diagnosed by fine-needle aspiration of a phantom cecal "mass".

Dear Dr. Bedrossian: Differential diagnosis of a submucosal cecal mass discovered by colonoscopy includes neoplasms such as carcinoid, lymphoma, leiomyoma, gastrointestinal (GI) stromal tumor, and lipoma, among others. However, infectious processes such as tuberculosis, actinomycosis, and ameboma in the ileal–cecal regions have been reported presenting as masses mimicking tumors. Giardia is the...

Acute Appendicitis Caused by Previous Endoscopic Submucosal Dissection for an Adenoma Adjacent to the Appendiceal Orifice

Endoscopic submucosal dissection (ESD) is a groundbreaking treatment for tumors adjacent to the appendiceal orifice that are difficult to remove by conventional endoscopic mucosal resection, and successful cases are increasingly reported. However, little is known about the subsequent complications, especially long-term complications. A female in her early 70s with a 15-mm cecal tumor adjacent t...
