Meningeal carcinomatosis as the initial clinical manifestation of a tumor is a very rare event and difficult to make diagnosis. Lumbar puncture is a single and useful diagnostic method, and meticulous cytologic study of cerebrospinal fluid specimen is needed for correct diagnosis. A case of meningeal carcinomatosis diagnosed by cytologic study of CSF and later confirmed primary carcinoma of the stomach by, fiberscopic biopsy is briefly presented. Meningeal signs and symptoms were the primary clinical manifestation in case.

A case of extrastkeletal Ewing's sarcoma on lower extremity in a 60-year-old male is reported. Extraskeletal Ewing's sarcoma is a rare malignant neoplasm that shows similar histologic and ultrastructural features to Ewing's sarcoma of bone. Histologically, the neoplasm was composed of small, round to oval cells with scant cytoplasm that were arranged in sheets with large area of necrosis. Electron microscopy of the neoplastic cells revaled scant cytopasm containing glycogen rosettes and a paucity of organelles. There is no ultrastructural evidence to indicate the origin of the cells.

Neurilemmoma*

The term malignant mesenchymoma has been applied to those tumors of the soft tissue of mesenchymal origin which are composed of tumor cells differentiating into two or more unrelated malignant forms in addition to the fibrosarcomatous element. Recently authors experienced a case of malignant mesenchymoma in the right axillary area. Microscopically the sarcoma revealed multiple pattern of differentiation, including liposarcoma, malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma and rhabdomyoblastoma. The presence of rhabdomyblastic cells were proved by immunochemical study utilizing desmin. This patient was treated with surgical excision and radiation.

Tuboovarian abscess associated with pregnancy is not commonly reported. Diagnosis may be difficult if the obstetrician is not aware that this condition can occur during pregnancy. The diagnosis is often made at laparotomy by a physician expecting appendicitis or another inflam-matory condition. A case of ruptured tuboovarian abscess on 34 weeks' gestation of pregnancy was presented and reviewed briefly.
