Leiomyoma of the sternothyroid muscle.

Background: Leiomyomas are benign cutaneous tumors of smooth muscle origin. Only a small percentage of leiomyomas arise in the head and neck region. We present the first case of leiomyoma arising in the sternothyroid muscle of the neck.

Case of Cerebral Amyloid Angiopathy-Related Inflammation - Is the Absence of Cerebral Microbleeds A Good Prognostic Sign?

Objective: The aim of this study is to describe a case of pathologically proven cerebral amyloid angiopathy-related inflammation (CAA-I) without cerebral microbleeds (CMBs) and its clinical course.

Background: CAA-I is an uncommon variant of cerebral amyloid angiopathy. Keys to diagnosis rely on the physician's awareness of this entity, CMBs on magnetic resonance imaging (MRI), an often favorable response to immunosuppression, and ultimately brain biopsy.

Pathologic reporting of lymph node metastases in differentiated thyroid cancer: a call to action for the College of American Pathologists.

Lymph nodes in differentiated thyroid cancer have many different histomorphologic features. The current AJCC staging system does not distinguish between different lymph node characteristics and is based entirely on the presence of metastatic disease to upstage pN0 to pN1. However, clinicians involved in the management of thyroid cancer recognize that there is a difference in the clinical significance of finding macroscopic versus microscopic nodes.
