title: Primary localized extranodal hodgkin disease of the transverse colon.
abstract: Extranodal Hodgkin disease presenting as a primary localized neoplasm is uncommon, with rare case reports describing primary sites other than lymph nodes. The gastrointestinal tract is the most frequent site of involvement by extranodal Hodgkin disease, typically involving the stomach or small bowel. To date, we have been able to find only one fully documented case of Hodgkin disease of the sigmoid colon confirmed by immunohistochemical studies. We report a case of extranodal Hodgkin disease involving the transverse colon, presenting as inflammatory bowel disease and documented by light microscopic, immunohistochemical, cytogenetic, and molecular studies.
