S100-EPISPOT: A New Tool to Detect Viable Circulating Melanoma Cells.

Metastatic melanoma is one of the most aggressive and drug-resistant cancers with very poor overall survival. Circulating melanoma cells (CMCs) were first described in 1991. However, there is no general consensus on the clinical utility of CMC detection, largely due to conflicting results linked to the use of heterogeneous patient populations and different detection methods.

Florid pseudoepitheliomatous hyperplasia related to tattoo: a case report.

Pseudoepitheliomatous hyperplasia is a benign condition defined by an exuberant proliferation of the epithelium with downward progression into the dermis. It may occur in reaction to several conditions including chronic cutaneous wound. We describe an unusual case of a florid pseudoepitheliomatous hyperplasia mimicking a well-differentiated squamous cell carcinoma, restricted to the red part of a rose tattoo.
