Vascular invasion in Stage I carcinoma of the cervix.

Vascular invasion was identified as an important prognostic variable for all lesion sizes in 138 patients with Stage I cervical carcinoma. A matched pairs analysis, controlling for lesion size and extracervical spread, showed that vascular invasion was significantly associated with poor outcome. Regression analysis also indicated that vascular invasion contributed prognostic information beyond that available from lesion size and extracervical spread.

Atypical leiomyoma of prostate.

A prostatic leiomyoma with nuclear atypia, similar in appearance to atypia sometimes seen in uterine leiomyomas, was an incidental finding in a fifty-three-year-old man who underwent prostatectomy for hyperplasia. The smooth muscle nature of the lesion was confirmed by electron microscopic examination. This is the third lesion of this type to be reported.

Subdural hematoma secondary to metastatic neoplasm: report of two cases and a review of the literature.

Subdural hematoma secondary to dural metastases is a rare event. Vascular obstruction due to invasion of dural vessels is an important etiological factor. When this is associated with a clotting defect, the subdural hematoma can cause significant clinical symptoms and death.
