Mucosectomy band ligation as a treatment for in situ esophageal carcinoma.

Esophageal squamous cell carcinoma (ESCC) remains the most prevalent subtype of esophageal cancer worldwide. Major risk factors include chronic alcohol consumption and heavy smoking. We present the case of a 65-year-old male with chronic alcoholism and a 75 pack-year smoking history, admitted for his first hydropic decompensation of alcoholic cirrhosis. The patient presented with abdominal distension and discomfort. Physical examination confirmed ascites, and further evaluation indicated decompensated cirrhosis. An upper gastrointestinal endoscopy revealed a 15 mm flat mucosal lesion located 35 cm from the dental arcade, classified as IIb according to the Paris Classification. The lesion had a denuded surface, and narrow band imaging (NBI) showed a brownish appearance with abnormal intrapapillary capillary loops (IPCL), suggesting a degenerative squamous lesion of the esophagus. A computed tomography (CT) scan showed no signs of distant metastasis. Histopathological examination of biopsies confirmed high-grade dysplasia (carcinoma in situ).

Diagnosis of non-Hodgkin's lymphoma due to a tiny polyp in the cecum.

Endoscopic findings in primary or secondary intestinal lymphoma are non-specific, which can lead to finding a polyp, an ulcer or a completely normal mucosa. As a matter of fact, this makes having a high clinical suspicion with only the endoscopic technique, quite difficult. Due to this reason, we believe that either taking random biopsies or biopsies from visible lesions of affected sections in another imaging tests, should be indicated in order to increase the diagnostic capacity of the endoscopic technique.
