Résumé

The purpose of this study was to describe the clinicopathological features of 40 cases of necrotizing non-granulomatous lymphadenitis in Thai patients. The clinical features, histomorphology and special stains were evaluated in 40 Thai patients from the pathology records of King Chulalongkorn Memorial Hospital from January 2001 to December 2003 in those diagnosed as having necrotizing non-granulomatous lymphadenitis. Of the 40 patients, 17 cases (42.5%) had Kikuchi-Fujimoto disease (KFD), 8 cases (20%) had tuberculosis (TB) lymphadenitis and 1 case (2.5%) had systemic lupus erythematosus (SLE) with associated lymphadenitis. Fourteen cases (35%) did not have a specific diagnosis due to a lack of follow-up data. KFD most commonly occurs in young women, and is characterized by the presence of coagulative necrosis and karyorrhexis often centered in the paracortex, an absence of neutrophils and plasma cells, proliferation of various cells composed of lymphocytes, histiocytes, immunoblasts and plasmacytoid monocytes and the absence of a granuloma. Tuberculous lymphadenitis usually occurs in women with a mean age of 34.25 years. The lymph nodes reveal extensive coagulative necrosis involving the cortex, paracortex and medulla, proliferation of mixed inflammatory cells, including neutrophils, lymphocytes and plasma cells in the necrotic area and the presence of proliferating histiocytes at the periphery of the necrotic area. The lymph nodes of SLE-associated lymphadenitis reveal large numbers of plasma cells and hematoxylin bodies. We suggest that necrotizing non-granulomatous lymphadenitis is not specific for any disease, but rather a common histologic change found in diseases, such as TB, SLE, and KFD. Further investigation to obtain a definite diagnosis should be done for appropriate treatment.

Résumé

Desmoplastic infantile ganglioglioma (DIG) is an uncommon neuroepithelial tumor associated with epilepsy, mostly occurring in the first 2 years of life. Most DIGs carry good prognosis after complete resection, even when a primitive cellular element is present. However a few examples of DIG with histologic anaplasia have recently been reported, and one demonstrated an unusual aggressive behavior. The authors describe herein a DIG with high Ki-67 proliferation index (30%) in a 10-month-old male infant with epilepsy, but with an excellent prognosis after total tumor resection.
