Résumé
Primary ovarian transitional cell carcinoma is extremely rare tumor. The histologic subtype was divided from malignant Brenner tumor due to it's own histologic characteristics and chemosensitive nature. Most of recent studies revealed that transitional cell carcinoma has a good response to chemotherapy and long-term survival. Recent histopathologic reports show that transitional cell carcinoma of the bladder and of the ovary are immunophenotypically different. We experienced a case of primary ovarian transitional cell carcinoma, and report this case with a brief review of the concerned literatures.

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

We studied the onset of coronary artery aneurysm formation in 42 patients of Mucocutaneous lymph node syndrome (MCLS), the serial changes of T cell subsets, and serum immunoglobulin levels including lgG, lgA, lgM, in 13 patients among them during acute (before high dose gamma-globulin therapy ) and subacute phase (after gamma-globulin therapy) to evaluate the role of the immunoregulatory abnormalities in coronary artery aneurysm formation. The following results are obtainded : 1) The coronary artery aneurysm was found in 16 patients (38%). They were detected in between 6th and 13th day of illness with the mean of 8.8+/-2.1 day. 2) The total T lymphocyte (T1), helper T lymphocyte (T4), and helper/supperessor ratio (T4/T8) decreased during acute phase. 3) Following gamma-globulin therapy it showed a increase in T4,T8, and all immunoglobulines. Above results showed that the most of aneurysms developed during acute phase and suppressed, rather than enhanced, T cell function significantly contributed to aneurysm formation, whereas high dose gamma-globulin retarded or reversed this suppression which would be one of mechanism of beneficial effort of gamma-globulin in MCLS.
