ABSTRACT
This chapter does not pretend to cover, in an exhaustive or even schematic fashion, all the disorders that can have repercussions affecting the scalp. Such an enterprise would require on its own an entire volume equivalent to the present one. The aim here is just to trace the major conditions most frequently encountered at this site, whether inflammatory or neoplastic, with apologies in advance to the reader for any overlapping of topics dealt with in other chapters such as those dealing with alopecia, seborrhea, or dandruff conditions.
