Comparison of p53 and CD44 variant 6 expression between paired primary and recurrent ovarian cancer: an immunohistochemical analysis.

Progression of malignant potential in ovarian cancer was investigated by comparing recurrent tumor with their primary tumor counterparts in terms of p53 and CD44 variant 6 (CD44v6) expression. Forty-three paired primary and recurrent tumors were immunohistochemically evaluated for expression of p53 and CD44v6. A paired analysis revealed that p53 and CD44v6 expression were significantly greater in recurrent tumors than those in the primary counterparts with statistical significance, respectively (P=0.0055 and 0.0071; Wilcoxon signed-rank test). No relationship between these two proteins was found. These results suggested that recurrent ovarian cancer may possibly express a stronger malignant potential in comparison to the primary tumor.

Alveolar rhabdomyosarcoma of the vulva. Report of two cases.

The cytologic and histologic findings in two cases of the extremely rare alveolar rhabdomyosarcoma of the vulva are reported. The tumor cells in fine needle aspiration smears from one case and tumor imprints from both cases were isolated or were in sheets or reticular patterns. The nuclei were round to oval; only a few cells were multinucleated. The chromatinic material was increased in amount and finely granular. Many mitotic figures were observed. The cytoplasm was scanty in general, but some cells had abundant cytoplasm; cross striations were not recognized. The tumor cells were positive with immunocytochemical stains for desmin, vimentin and myoglobin. Similar findings were observed in biopsy and surgical specimens.

Primary retroperitoneal mucinous cystadenocarcinoma: report of a case.

A case of primary retroperitoneal mucinous cystadenocarcinoma is presented. Ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) examinations demonstrated a large cystic tumor with solid excrescences. Angiographic examination demonstrated an avascular area with small areas of faint blush. It must be borne in mind that mucinous cystadenocarcinoma originating from the retroperitoneum can occur, although it is very rare.

Disseminated intravascular coagulation in transfusion-associated graft-versus-host disease. Report of two cases.

In two cases of transfusion-associated graft-versus-host disease (TA-GVHD), severe bleeding tendencies were observed besides the characteristic features of the disease. An elevation of fibrin degradation products (FDP), D-dimer, thrombin-antithrombin III complex (TAT) and plasmin-alpha 2 plasmin inhibitor complex (PIC), was revealed. These findings were compatible with disseminated intravascular coagulation (DIC). To our knowledge, the association of TA-GVHD and DIC has not been described, and it is our speculation that allogeneic immune reactions may play some pathogenic role in developing DIC in TA-GVHD. The DIC may be responsible for the rapid progression of multiple organ failure (MOF) in TA-GVHD.
