Sarcomatous Transformation in a Cellular Angiofibroma

A rare cellular angiofibroma of the epididymis

Combined Hepatocellular and Cholangiocarcinoma with Sarcomatous Transformation

Combined hepatocellular and cholangiocarcinoma with sarcomatous transformation was first recognized in Ramathibodi Hospital in 2005. This variant of carcinoma has been increasingly reported particularly from Asian countries. Dedifferentiation of the epithelial component to various sarcomatous components is likely the underlying mechanism. The causative factors of hepatocarcinogenesis in Thailan...

Cellular angiofibroma in women: a review of the literature

Cellular Angiofibroma (CA) represents a quite recently described mesenchymal tumour that occurs in both genders, in particular in the vulvo-vaginal region in women and in the inguino-scrotal area in men. The first description of this tumour dates from Nucci et al. article in 1997; since then, the literature reports different reviews and case report of this tumour in both genders, but no article...

High-grade malignant transformation of a radiation-naïve nasopharyngeal angiofibroma.

BACKGROUND Nasopharyngeal angiofibromas are typically considered benign vascular neoplasms, with descriptions of high-grade sarcomatous change found only in lesions with prior radiotherapy. METHODS AND RESULTS We describe the first reported case of high-grade malignant change in a nasopharyngeal angiofibroma naive to radiation. A 45-year-old man presented with left-sided nasal congestion and ...

A Giant Vulvar Mass: A Case Study of Cellular Angiofibroma

Cellular angiofibroma is a mesenchymal tumor that affects both genders. Nucci et al. first described it in 1997. Cellular angiofibroma is generally a small and asymptomatic mass that primarily arises in the vulvar-vaginal region, although rare cases have been reported in the pelvic and extrapelvic regions. It affects women most often during the fifth decade of life. The treatment requires simpl...
