[Paraneoplastic dermatoses in the area of the head].

Paraneoplastic dermatoses or cutaneous paraneoplastic syndroms are non neoplastic skin changes closely related to and in their manifestation influenced by an underlying malignancy. The ability to identify these skin changes is of particular importance. Thus, recognition is useful in the early diagnosis of an otherwise asymptomatic malignancy and may significantly affect survival. In this paper important clinical characteristics and commonly associated malignancies of paraneoplastic dermatoses also affecting the head are reported.
