%X <b><span style=\"font-family:Verdana;\">Background: </span></b><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">Terra Firma-Forme Dermatosis (TFFD), a benign skin condition which
presents with asymptomatic brown to black plaques which resemble dirty skin. </span><b><span style=\"font-family:Verdana;\">Aim:</span></b><span style=\"font-family:Verdana;\"> To document a new case presentation with TFFD in the Arab region which is
considered as one of the differential diagnos</span></span><span style=\"font-family:Verdana;\">e</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">s of dirty neck. </span><b><span style=\"font-family:Verdana;\">Case presentation: </span></b><span style=\"font-family:Verdana;\">A 15-year-old
girl presented with a history of asymptomatic brownish dirt-like lesion on the
nape and sides of the neck for 4-years duration, not resolved by wash with
water and soap and confused with other dermatos</span></span><span style=\"font-family:Verdana;\">e</span><span style=\"font-family:Verdana;\">s like acanthosis nigricans or atopic dermatitis.
The diagnosis of TFFD was confirmed when the lesions </span><span style=\"font-family:Verdana;\">were </span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">completely resolved after
gentle swabbing with 70% isopropyl alcohol. </span><b><span style=\"font-family:Verdana;\">Conclusion:</span></b><span style=\"font-family:Verdana;\"> TFFD is rarely
reported in Arab region and should be considered when evaluating cases of dirty
neck-like presentation of atopic dermatitis or acanthosis nigricans.
