Cutaneous myoepithelioma with a plexiform pattern of growth: a case report.

Cutaneous myoepithelioma, a recently recognized, rare but well-characterized entity, is comprised solely of myoepithelial cells. In this report, we describe a cutaneous myoepithelioma with a plexiform pattern of growth in the scapular region of a 58-year-old woman.

Preoperative parathyroid scintigraphic lesion localization: accuracy of various types of readings.

Purpose: To retrospectively compare the accuracy of various parathyroid scintigraphy readings for single-gland disease (SGD) and multigland disease (MGD) in patients with primary hyperparathyroidism, with histologic analysis as the reference standard.

Materials And Methods: Institutional review board approval was obtained for this HIPAA-compliant study. Records of 462 patients with primary hyperparathyroidism who underwent preoperative imaging with a technetium 99m ((99m)Tc) sestamibi and (99m)TcO4- protocol that consisted of early and late pinhole (99m)Tc sestamibi, pinhole thyroid imaging, image subtraction, and single photon emission computed tomography (SPECT) were retrospectively reviewed.

Incidence of metastatic well-differentiated thyroid cancer in cervical lymph nodes.

Objective: To determine the incidence of clinically positive lateral cervical nodes at presentation and after initial treatment in patients with well-differentiated thyroid cancer.

Design: Retrospective chart review.

Setting: University-affiliated teaching hospitals.

Sestamibi scans and intraoperative parathyroid hormone measurement in the treatment of primary hyperparathyroidism.

Objective: To assess the value of preoperative sestamibi scanning and intraoperative parathyroid hormone (IOPTH) measurement in the treatment of patients with primary hyperparathyroidism due to multiple gland disease (MGD).

Design: Retrospective medical record review.

Setting: Tertiary care academic medical center.

The value of frozen section examinations in determining the extent of thyroid surgery in patients with indeterminate fine-needle aspiration cytology.

Objectives: To determine the usefulness of intraoperative frozen section (FS) examinations in establishing the diagnosis of thyroid cancer in patients undergoing thyroidectomy for nodules with indeterminate cytological features and to determine the cost-effectiveness of FS examinations in this situation.

Design: Retrospective medical record review. The results of fine-needle aspiration biopsies (FNABs), FS examinations, and final pathologic examinations are compared.
