“…Despite these differences, the distinction between DN and TFFD becomes difficult at times and it seems that there exists clinical and histological overlap between the two conditions 3,4,6,7,9,10,13 . Some authors have suggested that the difference between TFFD and DN is arbitrary and TFFD may be a milder form of DN 14 . TFFD can simulate many dermatoses ( Table 1).…”

Duncan'ın kirli dermatozu olarak da bilinen Terra-firma forme dermatoz (TFFD), kir benzeri kahverengi gri renkli plaklar ile karakterize bir klinik tablodur. Anormal ve gecikmiş keratinizasyon patogenezinde rol oynar. Hastalıkta, tipik kir benzeri lezyonlar olsada, ayırıcı tanıda zorlanılabilir. TFFD'nin, %70 izopropil alkol ile silinerek giderilmesi tanı almasını ve tedavisini sağlar. Bu benign dermatozun tanınması, gereksiz hastane başvurularının, laboratuvar araştırmaları, deri biyopsileri ve ilaç tedavilerinin önüne geçilmesi için önemlidir. Bu yazıda yazar üç yeni TFFD olgusu bildirmektedir. Anahtar Kelimeler: Gecikmiş keratinizasyon, Duncan'ın kirli dermatozu, Terra-firma forme dermatozis, %70 izopropil alkol Terra-firma forme dermatosis (TFFD), also known as Duncan's dirty dermatosis, is characterized by "dirt-like" brown-grey cutaneous patches and plaques. Abnormal and delayed keratinization has been implicated in its pathogenesis. The disorder is not well known by dermatologists even though affected patients present with typical dirt-like lesions. TFFD can be easily diagnosed and treated with 70% isopropyl alcohol. It is important to recognize this benign dermatologic entity because it can be easily confused with many other dermatological conditions. Hence, in order to avoid unnecessary referrals, laboratory investigations, skin biopsies, and medications, a trial of wiping the skin lesion with 70% isopropyl alcohol pads is suggested whenever the diagnosis of TFFD is considered. In this article, the author is reporting three new cases of TFFD.

“…In the study of Asslan et al two patients were siblings and had xerosis, which may lead to a suspicion of the possible impact of inheritance on the occurrence of this disease, but more extensive studies are needed to confirm these assumptions (7). As a possible cause of TFFD, Ashique et al emphasize inadequate hygiene and inappropriate care of skin areas damaged by previous surgical interventions (13). Most of other authors did not establish a relationship of TFFD with poor hygiene or hygienic habits (3,10,12,13).…”

Most of other authors did not establish a relationship of TFFD with poor hygiene or hygienic habits (3,10,12,13). Patients often state that the changes occurred during warm periods and sometimes due to the intense exposure to the sun (1,8,10,12,14).…”

Terra firma-forme dermatosis (TFFD) or Duncan’s dirty dermatosis is a bizarre, acquired, and idiopathic dermatosis. It is characterized by its asymptomatic, yellowish, or brownish dirt-like lesions, resistant to usual washing with soap and water, but disappearing when rubbed with 70% ethyl alcohol or isopropyl alcohol. Swabbing with alcohol is both diagnostic and therapeutic means for this disorder. We present two boys, aged 14 and 11, with asymptomatic brownish, dirt-like lesions on the chest and forearms, respectively. Skin lesions were continuously present for more than a month. Both of the patients had usual hygiene habits. The diagnosis of TFFD was confirmed by rubbing with 70% ethyl alcohol which led to disappearance of the lesions. TFFD often causes much concern in patients and parents of affected children. Since its clinical picture is similar to some other dermatoses, the disease can be misdiagnosed. Therefore, it is important to recognize this dermatosis in dermatological and pediatric practice in order to explain the benign nature of the disease to patients and to avoid unnecessary diagnostic tests.
