A 42-year-old female patient was referred to our gastroenterology department with a 4-month history of weekly symptoms of dysphagia for solids and liquids. The patient also reported occasional symptoms of food impaction and heartburn. She denied nausea, vomiting, weight loss or a recent change in bowel habits. The patient was not under any medication. Medical or surgical history was unremarkable. There was no family history of gastrointestinal cancer. Physical examination was normal, and laboratory tests did not reveal anaemia or other abnormalities. She underwent an oesophagogastroduodenoscopy, and the oesophagus is shown in figure 1. Biopsies were performed in the upper and lower parts of the oesophagus and the result is shown in figure 2. Macroscopically and histologically, the stomach was normal. On the same day, the patient underwent a high-resolution manometry (HRM) (Medtronic 36-channel solid-state catheter) with 10 supine liquid swallows (5 mL water each) with the following findings (figure 3).
What is the diagnosis? How do we approach this patient? How is this treated?
This patient has lichenoid oesophagitis (LE). When LE is associated with lichen planus (LP) lesions and positive direct immunofluorescence (DIF) studies, it is defined as lichen planus oesophagitis (LPE). When LP lesions are absent and DIF studies are negative, it is defined as lichenoid oesophagitis pattern (LEP).1
Lymphocytic oesophagitis and LE may be in the same spectrum of disease since there are histological similarities, with the latter being distinguished by the presence of civatte bodies.1
LPE is more likely to occur in women, to progress to strictures and to be associated with rheumatological disorders, whereas LEP is more likely to affect the midoesophagus and to be associated with viral hepatitis and HIV infection. Both have a risk of neoplasia.1 In this case, DIF, autoimmune and virological studies were negative. Therefore, a diagnosis of LEP was made. An oesophagogastric junction outflow obstruction was seen on HRM.2 This is the first description of a manometric pattern associated with LE.
Treatment includes steroids and immunomodulators.1 A trial of oral prednisolone 40 mg/day was started with complete resolution of symptoms. After 8 weeks, under 10 mg, there was a significant histological improvement (figure 4). HRM revaluation was also normal. Currently, the patient is asymptomatic under azathioprine 2.5 mg/kg/day.
The key learning points are performance of midoesophageal biopsies in selected cases of non-obstructive dysphagia, performance of DIF studies in LE and exclusion of related diseases.
