title: [Nodular fibrohistiocytosis of the stomach].
abstract: The paper described 11 observations of peculiar nodulous formations of the stomach localized in the submucous layer and usually ulcerated. They consist of the connective tissue stroma with abundance of vessels in which polymorph cells of the immune system are deposited and there is an abundant eosinophilic infiltration. The structure of the formation resembles gradually fibrosing granulations. The process goes in waves. In some cases, lesions typical of the scarry tissue at the site of chronic ulcer were observed in the adjacent submucous layer and sometimes in the external muscle layer of the stomach. It is suggested that the described formation is associated with the healed ulcer, possibly under special conditions of the immune system stimulation. The morphological essence of the process is most completely described by the term "fibrohistiocytosis with tissue eosinophilia".
