Abstract

Terra firma-forme dermatosis (also called “Duncan’s dirty dermatosis”) and dermatosis neglecta (or “unwashed dermatosis”) are two nosological entities characterized by hyperpigmented lesions with a “dirty” appearance. Both conditions are infrequently described in literature, but their frequency in the general population is probably underestimated, because of missed identification by physicians and/or missed reporting due to their benign nature and rapid and complete resolution, in almost all cases with simple therapeutic measures. This chapter describes the morphological characteristics of the lesions and clinical history of the two conditions, which are the basis for their recognition and distinction from other hyperpigmented skin diseases, as well as the diagnostic tests which may be used in common practice to confirm diagnostic suspicion and the histopathological aspects. Finally, an overview is given of standard and alternative treatments, used for the treatment of cases with peculiar localizations and/or particularly extensive or severe.
