Brace yourself: an unusual case of knee pain, an extradigital glomangioma of the knee.

The differential diagnosis for knee pain is extensive. Glomus tumors comprise approximately 1.6% of soft-tissue tumors in the extremities. Classic subungual tumors occur more frequently in women, whereas ectopic locations are more common in men. Unusual locations include the stomach; lungs; trachea; bones; intestines; fallopian tubes; and intraneural, neuromal, and intravenous locations. We present the case of a 50-year-old man with a 12-year history of enlarging right knee mass found to be a glomangioma. This case report discusses the incidence, presentation, imaging characteristics, histology, and management of glomus tumors of the knee.

Preoperative Protective Endovascular Covered Stent Placement Followed by Surgery for Management of the Cervical Common and Internal Carotid Arteries with Tumor Encasement.

Objective The objective of this study was to report the outcomes on a preliminary cohort of patients with tumor encasement of either, or both, the cervical internal carotid artery (ICA) and common carotid artery (CCA) following preoperative covered stent placement and surgical resection. Setting This study was set at the University of Florida College of Medicine, Jacksonville, FL. Participants Subjects who received preoperative stenting of the cervical ICA/CCA before surgical resection of head and neck tumors between April 1, 2015, and July 31, 2015 were participated. Main Outcome Measures The outcomes assessed were resectability of tumors after stenting, histopathological assessment of specimen margins, complications associated with stenting. Results Five subjects received preoperative covered stent placement of the ICA/CCA before surgical resection. The mean age was 65.2 years. Median follow-up was 3.5 months. Excision of the adventitia from the stent was performed in all subjects. No intraoperative complications occurred. One vascular-related complication occurred in one subject who suffered occlusion of the stent, sustaining a ministroke. No involvement of tumor at the deep margin (inner surface of adventitia) of the resection was seen in any subjects. Conclusions Preoperative covered stent placement of the cervical ICA/CCA in the management of subjects with head and neck tumors who display encasement on preoperative imaging may represent a safe and effective treatment.
