Localized primary extranodal Hodgkin's disease is rare, especially in the digestive tract. A case is reported in which primary Hodgkin's disease presented as an ulcerated tumour of the sigmoid colon. The prognosis and management of such localized extranodal Hodgkin's lesions are discussed.
The case is reported of a 19-year-old patient with gastric carcinoma, in which clinical presentation (intermittent fever, myalgia, proximal muscle weakness and diffuse nodular-trabeculated infiltration of both lungs) was very unusual. The patient developed further complications (microangiopathic hemolytic anemia with disseminated intravascular coagulation) and died of subdural hematoma. Bone-marrow biopsy showed metastatic mucin-producing adenocarcinoma, but the gastric primary site of the tumor could only be demonstrated at autopsy.
Examples are reported of lymph node lesions simulating histologically and/or clinically malignant lymphomas. Two main categories of alterations have been distinguished: A. hyperplastic lymph node alterations associated with systemic disease and/or viral or drug-induced lymphadenitis; B. anatomo-clinical entities such as giant lymph node hyperplasia, massive lymphadenopathy with sinus histiocytosis, and angio-immunoblastic lymphadenopathy. It is suggested that in some situations such as angio-immunoblastic lymphadenopathy the borderline between reactive and enoplastic alterations is not clear cut. To evaluate such changes, close collaboration between the clinician, the hematologist and the patholigist is necessary.
