      A 77-year-old man with a history of total gastrectomy for gastric linitis (7 years before presentation) was referred to our center for abdominal pain and rectorragy. A 20-kg weight loss was noted. An upper gastrointestinal tract endoscopy was normal, and a colonoscopy revealed a circular tumoral mass occluding the inferior rectal lumen. The histopathologic evaluation of a biopsy specimen taken from the mass revealed poorly differentiated adenocarcinoma that was characterized by signet ring cells. A computed tomographic scan of the pelvis and abdominal area and a magnetic resonance imaging scan of the pelvis confirmed the circular tumor infiltrate with a longitudinal extension of 8 cm (Figure). Preliminary investigations excluded local or distant adenopathy or distant metastasis.
