title: Severe erosive stomatitis and giant lymph node hyperplasia of retroperitoneum (Castleman's tumor).
abstract: A severe, extensive, erosive stomatitis developed in a 33-year-old Japanese man who had had intraperitoneal giant lymph node hyperplasia (Castleman's tumor) of the hyaline-vascular type. Histologically, there was a dense lymphoid cell infiltration in the dermis with invasion of the mucosal epithelium. It was hypothesized that an autoaggressive attack of lymphoid cells against the epithelium of the oral mucosa played a role in the pathogenesis of this erosive stomatitis and it was suggested that there might be a correlation between the occurrence of stomatitis and the presence of Castleman's tumor.
