The pure epithelioid malignant schwanoma is a rare form of malignant schwanoma and differs from the ordinary epithelioid malignant schwanoma because of the absence of a spindle cell component. We present a case of purely epithelioid malignant schwanoma arising in the parapharyngeal area from vagus nerve without difinite evidence of von Recklinghausen's disease. The patient was a 28-year-old man with palpable right neck mass and swallowing difficulty during 2 years. The mass was an ovoid encapsulated tumor and measured 5x3x3 cm in dimension. The cut surface showed brownish tan homogeneous nodular appearance with partly myxoid area. Microscopically the tumor showed nodular pattern composed of epitheliod cells which were arranged in both tight clusters and stringy cords. The cells were ovoid in shape and had vesicular nuclei with single prominent eosinophilic nucleolei and sometimes abundant intracytoplasmic mucin. Mitoses were infrequent. Ultrastructural study showed rudimentary cell junction and degenerated cytoplasmic organelles including scattered mitochondriae, short segments of rough endoplasmic reticulum and lipid droplets. There were no definite basement membrane and melanosome. Immunohistochemical study showed the cells being positive for S100 protein, neuron specific enolase and myelin basic protein and negative for cytokeratin.

We report two cases of murine typhus diagnosed by indirect immunofluorescent test. The patients showed cardinal symptoms and signs such as fever and chill, general myalgia, intractable headache and typical rash. Laboratory values and histopathologic findings were compatible with murine typhus. The oral administration of doxycycline improved dramatically the clinical manifestations of the two CCLSPS.

OBJECTIVE: To observe changes in reflex threshold and gain in spastic muscles and to find useful parameters in biomechanical assessment of spasticity. METHOD: Ankle plantar flexor muscles of twenty two hemiplegic patients were stretched by isokinetic dynamometer. Stretching was done at the velocities of 10degrees/sec, 300degrees/sec, and at the threshold velocity (e.g. lowest velocity at which electromyographic evidence of stretch reflex was recorded). Peak eccentric torque, torque at joint angle of 20degrees, torque threshold angle, and stiffness index were measured. RESULTS: Peak eccentric torque and stiffness index were increased and torque threshold angle was decreased in hemiplegic side. Peak eccentric torque and stiffness index were increased at 300degrees/sec compared to 10degrees/sec. Stiffness index showed significant correlation with modified Ashworth scale at 300degrees/sec and threshold velocity. CONCLUSION: Both reflex threshold and reflex gain were changed in spastic muscles. Stiffness index was thought to be one of useful parameters in biomechanical assessment of spasticity.

Congenital M llerian anomalies of uterus are so infrequently encountered and endometriosis, primary infertility, hematometra, and urinary tract anomalies are claimed to be common complaints in women with unicornuate uterus. We report one case of rudimentary horn associated with agenesis of right kidney and pelvic endometriosis which is presented with brief review of literature about anomaly of the female genital tract.
