An Anatomic Variant of Persistent Median Artery in Association with Carpal Tunnel Syndrome: Case Report and Review of the Literature.

The persistent median artery can be a rare cause of carpal tunnel syndrome. We present an anatomic variant of this artery. A 47-year-old female patient with bilateral carpal tunnel syndrome was found to have bilateral patent, functional persistent median arteries (PMA) upon operative exploration.

Dorsal Wrist Ganglion Associated with Extensor Digitorum Brevis Manus: Case Report and Review of the Literature.

Aberrant accessory muscles are rare entities in the hand. The extensor digitorum brevis manus (EDBM) muscle is amongst them and may be seen in association with dorsal ganglion cysts. Distinguishing an EDBM muscle is relevant in the diagnostic consideration of a dorsal ganglion in order to facilitate and guide its proper treatment.

Intravascular Papillary Endothelial Hyperplasia (Masson's Tumor) of the Hand.

A nonspecific soft tissue mass of the hand can be difficult to diagnose due to the multitude of possible etiologies. In this case, we discuss our experience in diagnosing and treating intravascular papillary endothelial hyperplasia, or Masson's tumor, of the hand. The wide range of differential diagnoses and the morphological resemblance to angiosarcoma make Masson's tumor an important clinical entity to understand.
