1.Polyvesicular Vitelline Tumor of the Ovary: A case report .
Korean Journal of Pathology 1999;33(11):1102-1106
Polyvesicular vitelline tumor of the ovary is an extremely rare variant of yolk sac tumor. We present a case of pure polyvesicular vitelline tumor in a 43-year-old woman. Light microscopy revealed a predominantly polyvesicular pattern embedded in mesoblastic stroma with the cysts showing two type of lining; tall columnar and cuboidal, or mesothelioid cells. The lining atypical cells showed occasional mitoses and intracytoplasmic PAS positive hyaline globules. In some areas, the cystic space contained a large amount of intraluminal hyaline material. Immunohistochemically, alpha- fetoprotein and alpha-1-antitrypsin were detected as a fine granular deposit in the cytoplasm of epithelial cells and hyaline globules. Electron microscopically, marked specialization of the vesicular lining cells suggested a differentiation toward gut structures and mature yolk sac.

BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

7.Carcinosarcoma in Recurrent Lesion of Serous Cystadenocarcinoma of the Ovary: A case report.

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.

We report a rare case of adreno-hepatic fusion in a 63-year-old man with a traumatic hepatic rupture. The adrenal tissue was located beneath the Glisson's capsule of the liver, and measured 3.5x2x0.3 cm. On histologic examination, the ectopic tissue was composed of both adrenal cortex and medulla surrounded by a delicate capsule of connective tissue.
