Pseudoaneurysm of the Facial Artery after the Injection of Botox

Facial artery pseudoaneurysm is a rare lesion that can be mistaken for an epidermal cyst or other lesions. We present here the case of an iatrogenic pseudoaneurysm of the facial artery branch that was caused by Botox injection. Botox is frequently used for cosmetic and therapeutic purposes in any part of the body. We treated this lesion by performing aneurysmectomy, and the histopathologic analysis showed myxoid degeneration.

Intravenous Pyogenic Granuloma (or Lobular Capillary Hemangioma) Developed within the Right External Iliac Vein

A pyogeinc granuloma, also known as a lobular capillary hemangioma, is a benign vascular tumor of the skin and mucous membranes, which is common in infants and children. It usually presents as a rapidly evolving solitary, sessile, or polypoid vascular nodule. An intravenous pyogenic granuloma (IVPG) is a rare form of pyogenic granuloma, in which the whole lesion appears as a single polypoid mass projecting into the lumen of a vein. All reported cases of IVPG have been limited the head, neck, and upper extremity. We report a case of an intravenous pyogenic granuloma located within the iliac vein of a lower extremity.
