Scalp tumors.

Tumors of the scalp are characterized by an impressively broad and heterogeneous clinical spectrum. They frequently exhibit site-specific features distinguishing them from their counterparts elsewhere on the skin. Although mostly benign, diagnosis and treatment of these lesions may pose a significant challenge due to impaired visibility (and thus delayed detection), anatomical circumstances, exposure to (exogenous) noxious agents, distinct histological features, as well as the often-advanced age of affected individuals. This is even more true for malignant tumors of the scalp, which are uncommon but associated with a poor prognosis. Adequate patient care therefore requires interdisciplinary management. Against this background, the present article addresses general principles and distinct features of the most important tumors of the scalp.
