Epidermotropic cutaneous metastases of squamous cell carcinoma from primary esophageal cancer: report of a case and review of the literature

Metastatic squamous cell carcinoma (SCC) to the skin can be distinguished histologically from primary cutaneous squamous cell carcinoma as, unlike the latter, it is typically separated from the normal overlying squamous epithelium. Rare cases have been reported of cutaneous metastases of SCC that demonstrate continuity with the overlying benign squamous epithelium, termed "epidermotropic cutaneous metastases of SCC." We report the first case of epidermotropic cutaneous metastases of SCC originating from primary esophageal SCC with a review of the literature on this rare histological phenomenon

Anaplastic large cell lymphoma localized to the left breast years after radiotherapy for breast cancer

Anaplastic large cell lymphoma (ALCL) is a rare type of non-Hodgkin lymphoma that can involve the skin primarily or secondarily. Our case describes an unusual presentation of eruptive tumors localized to the leftbreast region several years following breast cancer surgery and radiation for carcinoma of the breast. This report highlights the challenges in reachingthe diagnosis of an aggressive systemic lymphoma presenting on the skin

Skin cancer screening: recommendations for data-driven screening guidelines and a review of the US Preventive Services Task Force controversy

Melanoma is usually apparent on the skin and readily detected by trained medical providers using a routine total body skin examination, yet this malignancy is responsible for the majority of skin cancer-related deaths. Currently, there is no national consensus on skin cancer screening in the USA, but dermatologists and primary care providers are routinely confronted with making the decision about when to recommend total body skin examinations and at what interval. The objectives of this paper are: to propose rational, risk-based, data-driven guidelines commensurate with the US Preventive Services Task Force screening guidelines for other disorders; to compare our proposed guidelines to recommendations made by other national and international organizations; and to review the US Preventive Services Task Force's 2016 Draft Recommendation Statement on skin cancer screening
