A case of desmoplastic fibroma of mandible in a 18 years old woman is presented. She had complained progressive swelling of right mandible for 4 years. Radiographically, a multilocular radiolucent of right hemimandibulectomy showed multinodular external surface without cortical destruction. Cut surfaces revealed grayish white, fibrous homogeneous appearance with firm consistency, sparing head portion. The maximum diameter of the tumor was 13 cm. Microscopically, the tumor was composed of interlacing bundles of monomorphic spindle-shaped cells with abundant intercellular collagen. Ultrastructurally, most tumor cells were fibroblastic-like cells with abundant RER and cytoplasmic fibrils, but a few disclosed transition to myofibroblasts. However, no fully developed myofibroblasts were seen.

Malignant mixed mesodermal tumor (MMMT) of the ovary is endometrioid tumor containing epithelial and mesenchymal components. The mesenchymal component may be homologous, in which case the term carcinosarcoma is often used, or heterologous, containing cartilage, striated muscle, osteoid, bone, or fat, or combination of these elements. MMMT usually afflicts the postmenopausal woman and occurs more often in the nulliparous female. The disease is usually advanced (stage III) when diagnosed. Cliniopathologic data were presented for 3 cases of MMMT of the ovary with review of literatures. Clinical history substantiated previous reports in postmenopausal women wit this tumor. Symptoms were the same as for ovarian malignancy in general. All the patients presented wit stage II disease, according to the International Federation fo Gynecology and Obstetrics (FIGO) classification. Two patients died of tumor 4 and 10 months after operation, respectively. One patient had been alive at 2 months after operation. None of 3 cases demonstrate evidence of endometriosis in the remaining ovaries. Microscopically, periodic acid-Schiff (PAS)-positive, diastase-resistant hyaline droplets were found frequently in undifferentiated mesenchymal stroma and epithelial structures. The clinical significance and origin of the hyaline droplets in MMMT should be further explored.

Postoperative CT scans for accuracy of pedicular screw placement were assessed in 20 patients (82 pedicular screws) treated with several kinds of pedicular screws. When putting screws, the position of the guide pin was confirmed by the image intensifier. The measurement of canal encroachment from the medial border of the pedicle and the angle of insertion through the body of each vertebra were assessed; 1. Fifty-five(69.1%) were placed within the pedicle. 2. Ten(12.2%) were placed within 2mm of the medial border of the pedicle. 3. Three(3.6%) had 2mm to 6mm canal encroachment with the patient developing neurologic complication that was improved 8 months after the operation. 4.Fourteen(17.1%) perforated the lateral border of the pedicle, but they were not associated with neurologic complication. 5. The screws placed within 2mm of the medial border of the pedicle had higher angle of insertion than the screws exactly within the pedicle. Even with the use of image intensifier, there was a high rate of pedicle disruption. We have to insert the screws more exactly according to true anatomic angle of the pedicle on each level of every vertebra from the entry point avoiding high angle of insertion to prevent any disruption of the medial border of the pedicle which may result in neurologic complication.

Electron microscopic study of two malignant fibrous histiocytomas confirmed the presence of previously described tumor cells in the literature. In addition, there existed intermediate cells with morphologic features of both myofibroblasts and histiocytes, or both histiocytes and smooth muscle cells. Our result supported the idea that malignant fibrous histiocytoma may be derived from the undifferentiated mesenchymal cells that differentiate primarily along a fibroblastic and histiocytic cells.

Congenital subglottic stenosis of the larynx is one of the most common cause of chronic airway obstruction im infancy and childhood. It is defined as narrowing of the space bounded inferiorly by the inferior margin of the cricoid cartilage amd superiorly by the insertion of the fibers of the conus elasticus into the true vocal cords. In case we experienced was a female full-term baby delivered by Cesarean section. The stenosis was believed by hypertrophy of stromal soft tissue and cricoid cartilage in the subglottic area. The lesion was associated with tracheoesophageal fistula of H1 type. A brief review of the literature was done.

Breast carcinoma has been infrequently reported in children. About 25 cases have been reported in world literatures since first description in 1913, by Bryan. We present a case of juvenile breast carcinoma in a 17 months old girl with brief review of literatures. Grossly, the submitted specimen is grayish white and measured by 1.3x1.0x0.8 cm in size. It is not encapsulated and its cut surfaces are homogeneous. Microscopic examination showed a neoplastic proliferation of duct cells forming mainly glandular spaces with focal papillary pattern, solid sheets or cribriform pattern. The glandular spaces were filled with collections of PAS-positive eosinophilic secretory materials. The individual cell varied from columnar to polygonal and showed moderate hyperchromatism and variation of nuclear size. Mitoses and necrosis are not found. Tumor cell invasion into the stroma was found.
