Rare breast lesions: correlation of imaging and histologic features with WHO classification.

Mammographers occasionally are surprised by the diagnosis of a rare lesion at breast biopsy. The imaging features of some breast lesions are unfamiliar because they are rarely seen in routine mammographic practice and they are not well described or well documented in the radiologic literature. Moreover, there may be wide variation in the appearances of rare breast lesions at mammography and ultrasonography (US).

Characterization of sonographic and mammographic features of granular cell tumors of the breast and estimation of their incidence.

Objective: The purpose of this series was to review the spectrum of sonographic and mammographic features of granular cell tumors (GCTs) of the breast and to compare their frequency relative to breast carcinoma.

Methods: Ten cases of a breast GCT diagnosed during the last 13 years were analyzed for the imaging characteristics and clinical features. Sonographic images were reviewed for location, size, echogenicity, margins, height-width ratio, and sound transmission.

Outpatient therapeutic 131I for thyroid cancer.

Objective: We retrospectively analyzed the safety, cost effectiveness, and patient acceptance of outpatient high-dose 131I treatment for thyroid cancer at our hospital since 1997, when the Nuclear Regulatory Commission began allowing high-dose outpatient therapy with radioiodine.

Methods: Forty-eight patients were treated as outpatients because their living conditions were acceptable and they were willing to comply with radiation safety guidelines. The homes of 3 patients were surveyed for contamination.
