OBJECTIVE To demonstrate the role of angiogenesis in the progression of cutaneous squamous cell carcinoma. INTRODUCTION Angiogenesis is a pivotal phenomenon in carcinogenesis. Its time course in cutaneous squamous cell carcinoma has not yet been fully established. METHODS We studied the vascular bed in 29 solar keratoses, 30 superficially invasive(More)
METHODS: We studied the vascular bed in 29 solar keratoses, 30 superficially invasive squamous cell carcinomas and 30 invasive squamous cell carcinomas. The Chalkley method was used to quantify the microvascular area by comparing panendothelial (CD34) with neoangiogenesis (CD105) immunohistochemical markers. The vascular bed from non-neoplastic adjacent(More)
Multistep carcinogenesis involves loss of function of tumor suppressor proteins such as p53 and induction of angiogenesis. Such mechanisms contribute to cutaneous squamous cell carcinoma progression and may be interconnected. We aimed to explore p53 immunoexpression in spectral stages of cutaneous squamous cell carcinoma and correlate expression to both(More)
