VIM and sarcomatoid carcinoma: Both carcinoma and sarcomatoid spindle cell elements are positive for pancytokeratin AE1/AE3, while spindle cells are positive for vimentin.[19] Occasionally, spindle cell carcinoma of the stomach presents with complicated symptoms, such as hematochezia and weight loss due to fistulous tract formation in the colon.[20] In addition, a 76-year-old man had a 6 cm sarcomatoid carcinoma of the remnant stomach after distal subtotal gastrectomy with a duodenal ulcer 28 years ago.[21]
