Is a Partial Anterior Cruciate Ligament Tear Truly Partial? A Clinical, Arthroscopic, and Histologic Investigation.

Purpose: (1) To determine whether examination under anesthesia (EUA) and/or magnetic resonance imaging (MRI) is an accurate means for determining patient selection for a selective-bundle reconstruction, (2) to determine whether the preoperative clinical assessment correlates with the arthroscopic examination, and (3) to examine histologically whether a partial anterior cruciate ligament (ACL) tear is truly partial in terms of vascular insult.

Methods: This prospective, nonrandomized cohort study included 95 patients who underwent primary ACL reconstruction from January 2013 through May 2014. All patients underwent an EUA, MRI, and arthroscopic evaluation.

Case report 714. Postirradiation osteosarcoma after radiation of metastatic skeletal lesion.

Two cases of postirradiation osteosarcoma are presented--one in a 76-year-old woman with breast carcinoma and subsequent osteosarcoma after radiation therapy for a metastatic lesion in the right tibia, and the other in a 16-year-old girl with hepatocellular carcinoma metastatic to the left tibia and osteosarcoma after radiation therapy to that bone. Microscopically, both cases were high-grade spindle cell lesions with osteoid production. Both patients fared poorly.

Ductal adenoma of the breast with tubular features. A probable component of the complex of myxomas, spotty pigmentation, endocrine overactivity, and schwannomas.

The features of ductal adenoma of the breast, a solid intraductal tumor, include the following: arrays of long, straight, narrow, roughly parallel tubules composed of distinct epithelial and myoepithelial cells; a modest amount of fibrous tissue that separates the ducts from one another; and a fibrous capsule. We found this neoplasm in four women (ages 27 through 61 years) who had the complex of myxomas, spotty pigmentation, endocrine overactivity, and schwannomas, an autosomal dominant familial syndrome. The lesion was bilateral in two of the women.

Myxoid fibroadenoma and allied conditions (myxomatosis) of the breast. A heritable disorder with special associations including cardiac and cutaneous myxomas.

Among 145 patients with the complex of myxomas, spotty pigmentation, endocrine overactivity, and psammomatous melanotic schwannomas, 31 (21%) had mammary lesions. The ages of these 26 females and five males ranged from 6 to 64 years (mean, 30 years). Five patients had breast symptoms.
