Mucosal adenocarcinoma of the descending duodenum is a very rare gastroin
A 61-year-old woman who was hospitalized with recurrent abdominal pain for more than 20 days. The patient developed epigastric pain with no obvious cause more than 20 days prior, mainly left epigastric pain and middle epigastric pain, and presented persistent dull pain without nausea or vomiting, fever or chills. The patient was treated at a local hospital, gastroscopy revealed a new lesion in the circum-intestinal cavity in the descending part of the duodenum, and pathological biopsy revealed mucous adenocarcinoma in the descending part of the duode
Mucosal adenocarcinoma of the descending duodenum has a high misdiagnosis rate and missed diagnosis rate, clinical manifestations lack specificity, and pathological diagnosis is the main basis for diagnosis.
Core Tip: The pathological diagnosis and clinical features of a rare case of descending duodenal mucosa adenocarcinoma were analyzed. Through detailed pathological examination, we confirmed the histological type of the tumor, combined with the patient’s clinical manifestations, imaging findings and treatment response, and comprehensively analyzed the pathogenesis, progression and prognosis of the case. The research focuses on revealing the diagnostic difficulties and treatment challenges of such rare tumors, aiming to provide references for clinicians and improve the level of diagnosis and treatment of similar cases.
