With a lifetime incidence of approximately 10% in the general population, cutaneous squamous cell carcinoma (CSCC) is the second most common type of nonmelanoma skin cancer. Most CSCCs are benign and can be completely eradicated by surgery or other dermatological procedures. There is, however, a subgroup associated with an increased likelihood of lymph node metastases and, therefore, with high morbidity and mortality. This article analyzes the various factors that define aggressive CSCC. We propose a method for defining high-risk SCC on the basis of a series of major and minor criteria. This method will allow better prognostic evaluation and enable personalized management of patients with high-risk SCC, possibly leading to improved overall survival.
Bilateral periorbital edema and swelling are frequent in clinical practice and are commonly attributed to orbital contact dermatitis due to different drugs and cosmetic products. However, when there is a background of a solid cancer, the possibility of eyelid metastasis should be also considered. Metastases to the eyelids are rare, and in most cases, these lesions are unilateral. Because only a few cases of bilateral involvement have been reported in the literature, clinical and morphological data of this variant are under recognized. We report the clinical and histopathological characteristics of 2 patients with 4 eyelid metastasis and review the previous cases reported in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
