Originally from Spain, where he had been living for 6 years after having lived in Colombia and Ecuador for 5 years. His usual treatment was lormetazepam 2 mg and omeprazole 20 mg/day. He came to the emergency department for progressive weight loss of 15 kg in the last 2 months, without associated anorexia. He had experienced episodes of mild generalised abdominal pain, together with dysphagia to solids and early postprandial fullness. Symptoms were relieved by occasional vomiting of food, with worsening in the last 6 weeks. Physical examination revealed a significant mucocutaneous dryness with preserved general condition and normal vital signs. No palpation of peripheral lymph nodes. Rhythmic heart tones, no murmurs. Excavatum, soft abdomen with no abnormal enlargement. Lower limbs without oedema or signs of deep vein thrombosis. Laboratory tests showed acute renal failure with a pre-renal profile and no electrolyte abnormalities. CBC and coagulation without anomalies. The systematic urine analysis showed ketonuria and the chest X-ray showed an anterior mediastinal widening with the presence of an air-fluid level inside. Given the high suspicion of an underlying neoplastic process, tests were arranged preferentially to accelerate the workup. <span class="elsevierStyleItalic">Trypanosoma cruzi</span> serology was negative. A cervicothoracic CT scan showed a stenosing mass at the gastroesophageal junction with severe retrograde oesophageal dilatation and retained food debris (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). This was a major limitation for performing an upper gastrointestinal endoscopy, requiring 3 attempts, hospital admission, insertion of a nasogastric drainage tube, establishment of total parenteral nutrition and fasting for 72 h in order to achieve its performance. This showed an oesophageal dilatation with a tortuous appearance, without endoluminal lesions. Finally, an endoscopic ultrasound revealed a submucosal thickening at the subcarinal level with biopsy, which reported fibromuscular hyperplasia in the lamina propria, abundant lymphoplasmacytic infiltrate in the lamina propria and muscularis mucosae, and absence of intestinal metaplasia. Positron emission tomography (PET/CT) showed no pathological uptake at the gastroesophageal junction or at other distant sites. The study was completed with a manometry that showed a total absence of peristalsis and a pressurisation pattern compatible with type 1 achalasia. The patient’s final diagnosis was inflammatory pseudotumour at the gastroesophageal junction secondary to type 1 achalasia. Endoscopic dilatation with a 20 mm balloon was performed without complications, after which clinical improvement was observed. At the subsequent 3-month follow-up visit, there were no new episodes of dysphagia or vomiting, and weight gain was observed.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0020" class="elsevierStylePara elsevierViewall">There are few reported cases secondary to oesophageal inflammatory pseudotumour.<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2–4</span></a> It is an exceptionally rare entity, which makes it a diagnostic and therapeutic challenge. The aetiology is unknown; some authors suggest that the origin of this lesion is an inflammatory response to mucosal ulceration, while others attribute it to gastroesophageal reflux. It usually affects the submucosal layer in the lower portions of the oesophagus, with reactive cells, myofibroblasts and fibroblasts being confirmed histopathologically, together with inflammatory cells, dysplasia and in some cases pseudomalignant mesenchymal cells.
