Neoplasms showing both carcinomatous and sarcomatous features are well established, and have been reported in practically every organ where carcinoma can occur. But the difference in terminology and difficulties in histopathologic interpretation have hampered adequate understanding of these neoplasms. We report a case of carcinosarcoma in the recurrent form of serous cystadenocarcinoma of the ovary. The patient was a 64-year-old female who underwent total hysterectomy and bilateral salpingoophorectomy three years ago, due to perforated papillary serous cysta denocarcinoma of the right ovary. Recurrent pelvic masses contained both carcinomatous and sarcomatous components. Morphological transition between carcinomatous and sarcomatous components, and epithelial characteristics in the sarcomatous component by immunohistochemistry were recognized. We postulate the histopathogenetic mechanism based on the phenotypic conversion of carcinoma into sarcoma in the carcinosarcoma.

A case of an ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma is reported. The patient was a 46-year-old female with a right ovarian cystic mass and underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The patient died of the disease in five months. Macroscopically, the right ovarian cyst wall contained numerous well-demarcated mural nodules. Histologically, the cysts were mucinous cystadenocarcinoma, and the nodules were composed of sarcoma-like spindle and polygonal cells with atypia and numerous mitoses. Spindle cells in the mural nodule showed epithelial characteristics by electron microscopy and immunohistochemistry. This case supports an epithelial origin of the mural nodule of anaplastic carcinoma in ovarian mucinous tumors.

The mutation of p53 tumor suppressor gene is the most common genetic variation of primary malignant tumors. The occurrence, progression and reaction for medical management of cancers can be different according to the characteristics of p53 gene, even if they are same kinds of malignant tumors. In this study, the property of p53 gene in 4 kinds of squamous cell carcinoma cell lines were investigated by using immunocytochemistry, PCR-SSCP, sequencing and Western blot methods. As a result, p53 mutation detected in 3 kinds of squamous cell carcinoma cell lines. Namely, it is found that T in codon 176 changed to A, and G in codon 281 changed to A in KUMA3 cell lines; CC in codon 241 changed to TT in KUMA4 cell lines; G in codon 266 changed to T in KUMA6 cell lines. In single nucleotide polymorphism of codon 72 of p53 gene, the genetic variations are Arg/Pro heterozygote in KUMA3 and KUMA4 cell lines; Arg/Arg homozygote in KUMA5 cell lines; Pro/Pro homozygote in KUMA6 cell lines. These results will provide useful data for p53 gene researches of various squamous cell carcinomas.

Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.

Iliac vein compression syndrome is a rare clinical condition in which left common iliac vein is anatomically compressed between right common iliac artery and the fifth lumbar vertebrae or pelvic brim. Patients usually have marked edema of the left leg. Although the actual incidence is unknown, this syndrome most affects women in the second to fourth decade of life. We report 4 cases of iliac compression syndrome treated by surgical intervention during the last fifteen-year period. Among them, two women have suffered from chronic intermittent swelling and pain of left leg, and two men had acute or subacute symptoms. The fibrous web in the entrance of left iliac vein into vena cava existed in one case. Including this one, two were treated by transposition of iliac artery or vein with thrombectomy. One was decompressed the arterial compression by mobilization or adhesiolysis of the surrounding vessles with thrombectomy. To the last one in which the distal common iliac vein was compressed by tortous dilated left internal iliac artery, transsection and ligation of the internal iliac artery was performed. All patients have experienced improved left leg condition after operation. except the last one in which suffered from thrombosis of left popliteal vein after the iliac decompression.

We report a case of histiocytoid hemangioma (angiolymphoid hyperplasia with eosinophilia) in a 60 year-old female patient who was effectively treated with dapsone. The therapeutic effect of dapsone may support the hypothesis that immunologically mediated reactive process plays a role in the pathogenesis of histiocytoid hemangioma.
