RESUMEN
Aggressive angiomyxoma (AA) is a rare, locally infiltrating soft tissue tumor typically located in the genital tract of young, reproductive age women. Surgical excision has been the mainstay of treatment. Recently, gonadotropin-releasing hormone agonist therapy has been reported to decrease the size of estrogen-receptor positive AA. We present the first case of a postmenopausal woman treated with an aromatase inhibitor to shrink the size of tumor prior to surgical resection.

A case of pathologic fracture of a mandibular condyle due to a primary adenocarcinoma of the rectum is presented. This is the first reported case of a secondary adenocarcinoma from the rectum to this site. Secondary metastases to the condyles are extremely rare. Only twelve have been reported in the literature. The primary tumor was from an unknown site in three cases (anaplastic adenocarcinoma); from the breast in four; and from the lung, liver, prostate, uterus, and hallux (a malignant melonama) in the remainder. Only of these tumors presented as a condylar fracture, and that was from a primary breast adenocarcinoma.

A stratiform, massive copper sulfide deposit with possible gold, silver, and cobalt credits was discovered by a United Nations reconnaissance team in Paleozoic (?) metamorphic terrain of north central Turkey. The deposit, which is of possible volcanigenic exhalative origin, contains evidence of extensive prehistoric underground mining and smelting activity that, based on radiocarbon data, may date to 2800 B.C. (Early Bronze I Age).
RESUMEN
Late Tertiary silicic ashflow tuffs and lavas peralkaline in chemical character (atomic Na + K greater than Al), mainly comendites, occur over wide areas in northwestern Nevada and appear to be widespread in southeastern Oregon. Such peralkaline rocks-which are not uncommon in the western United States-and other chemically unusual silicic rocks are found near the margins rather than toward the center of the Great Basin.
