title: Study of upper gastrointestinal tract involvement in pemphigus by esophago-gastro-duodenoscopy.
abstract: BACKGROUND
  Involvement of upper gastrointestinal tract in pemphigus vulgaris is not uncommon.
  
  
  OBJECTIVE
  To study the involvement of upper gastrointestinal tract (UGIT) with the help of esophago-gastro-duodenoscopy (EGD) in patients of vesiculobullous dermatoses with emphasis on pemphigus vulgaris.
  
  
  METHODS
  Forty-two patients (M-22, F-20) with vesiculobullous dermatoses, diagnosed on the basis of clinical features and skin histopathology as pemphigus vulgaris (PV)-40 patients and pemphigus foliaceus (PF)-2 patients were included in the study. The EGD was performed and mucosa of the esophagus, stomach and first part of the duodenum were examined. Mucosal biopsies were taken from the lower esophagus in 26 patients of PV and studied after H and E staining.
  
  
  RESULTS
  On EGD, esophageal involvement was seen in 67% patients of PV (27/40). Of these, Grade I esophagitis was observed in seven, Grade II in 11, Grade III in four and Grade IV involvement was seen in five patients of PV. Three PV patients had associated esophageal candidiasis. Involvement of esophageal mucosa was also observed in one out of two patients of PF. Gastric mucosa was involved in 52% and duodenal mucosa in 20% of PV patients. Acantholysis was observed in seven out of 26 (27%) esophageal biopsies of PV patients. Two patients of PV vomited a tube-like structure, indicative of 'esophagitis dissecans superficialis'. The involvement of the gastric mucosa in patients with history of oral corticosteroid intake (60%) was compared to the group without history of oral corticosteroids (30%).
  
  
  CONCLUSIONS
  Among PV patients under study, significant involvement of oral (87%), esophageal (67%), gastric (52%) and duodenal mucosa (20%) was observed.
