Organochlorine levels in North Atlantic right whale (Eubalaena glacialis) blubber.

Polychlorinated biphenyls (PCBs), total DDT (DDT + DDE + DDD), dieldrin, heptachlor epoxide, chlordanes, and hexachlorobenzene (HCB) were found in blubber biopsies from endangered North Atlantic right whales (Eubalaena glacialis) in the Bay of Fundy and on Browns-Baccaro Banks. Analyses included four sex and age class composite samples from 1988, and 21 individual samples from 1989. Generally, PCBs demonstrated the highest wet weight residue levels (up to 1.9 micrograms/g), followed by total DDT (DDT + DDE + DDD) (trace to 0.47 micrograms/g). Relatively low residue levels in adult females suggest that transmammary organochlorine (OC) residue transfer occurs during lactation. The actual blubber residue loads may have been underestimated, because the samples were taken when the whales were depositing fat reserves and the samples may not have been representative of the remainder of the blubber.

Adrenal myelolipoma: rationale for nonoperative management.

With increasing use of computerized tomography and ultrasonography, asymptomatic lesions of the adrenal gland are frequently detected. One such tumor is the adrenal myelolipoma, composed of adipose and hemic elements histologically resembling bone marrow. This tumor can be diagnosed by its characteristic appearance on CT scan, and fine-needle biopsy guided by CT can be used to obtain a tissue diagnosis. Because patients with adrenal myelolipoma typically have recurrence of symptoms after resection, surgical intervention is not indicated unless an enlarging tumor impinges on surrounding structures.

Myoid hamartomas of the breast.

Tumors containing smooth muscle are rare in the breast. A myoepithelial origin for the myoid component of such lesions was postulated in previous reports. Myoepithelial hyperplasia has long been recognized as a common component of some breast lesions, including sclerosing adenosis, papillomas, and fibroadenomas. Three breast tumors composed of variable admixtures of adipose tissue, fibrous tissue, and smooth muscle are described. The authors postulate that the myoid component of two of the three lesions may have arisen in a milieu of myoepithelial hyperplasia. The origin of the myoid component in the third case is not clearly defined.
