Pazopanib as Treatment Option for Pseudomyogenic Hemangioendothelioma: A Case Report

Abstract

Pseudomyogenic hemangioendothelioma (PHE) also known as epithelioid sarcoma-like hemangioendothelioma (ES-H) is a vascular lesion of intermediate grade biologically behaving between benign hemangioma and malignant angiosarcoma. We present a 35-year-old male with an unremarkable medical history, who was referred to a sarcoma clinic complaining of right heel pain with equinus deformity and a mass in his right lower limb for 6 months. Biopsy was performed and reported as Pseudomyogenic Hemangioendothelioma. The patient was started on pazopanib with a favorable clinical and radiological response. Long-term follow-up is still needed, however further studies are vital to clarify the role of Tyrosine Kinase Inhibitor therapy.

Engineering considerations for practical lithium–air electrolytes

“…They are the charge-reversed versions of the peruorinated ammonium chlorides, which are ionic liquids. [64][65][66] The strong electron-withdrawing effect of the peruorinated chains around the boron strengthens the B-C bond and similar electrolytes have been used in battery systems. 67,68 Additionally, in the undiluted form, they would enable perfect lithium transference.…”
