“…Since TFFD is a retention hyperkeratosis, other keratolytic agents (such as salicylic acid, alpha--hydroxy acid, topical retinoids or even lemon juice) have also proven to be effective. 10 TFFD main differential diagnoses are dermatosis neglecta and acanthosis nigricans. 3,5,9 Dermatosis neglecta, as the term implies, results from a neglected hygiene, whereas in TFFD patients maintain adequate washing habits.…”

Terra firma-forme dermatosis is a dermatological condition characterized by the presence of hyperpigmented plaques, which are easily cleared with 70% isopropyl alcohol.CASE 1: A 14-year-old boy, with no relevant past medical history, presented with a brown-colored skin lesion on his chest, which had appeared one year earlier. The lesion was cleared with 70% isopropyl alcohol, proving the diagnosis of terra firma-forme dermatosis.CASE 2: A 12-year-old girl was referred to our consultation. She was obese and had insulin-resistance. On physical examination she had significant hyperpigmentation on her neck and axillae, which was interpreted as acanthosis nigricans. Nonetheless, we performed swabbing of the lesions with 70% isopropyl alcohol, which immediately cleared the skin, confirming the diagnosis of terra firma-forme dermatosis. In conclusion, terra firma-forme dermatosis is a benign and easily solved dermatosis. Nonetheless, its unesthetic appearance is often a cause of great distress to the patient. We aim to increased awareness of this entity.

Introduction: Terra firma-forme dermatosis is a benign condition and it can affect anyone, but it seems to be more common in children and young adults. It may appear as brownish or black spots that look like dirt. Typically, affected individuals are asymptomatic. Case description: A healthy 3-year-old girl, presented in our clinic with a 6-month history of brownish spots that looked like ‘dirt’, which were spread through the chest and flanks. After examination, we suspected that it was terra firma-forme dermatosis, so we rubbed the affected areas with gauze soaked in 70% isopropyl alcohol, thus removing these stains. After two months, the child presented with no injuries. Comment: Terra firma-forme dermatosis can be diagnosed and treated with the rubbing of gauze embedded in 70% isopropyl alcohol in the affected areas. It is important to prevent skin xerosis, by using smoothing cream with keratolytic agents like salicylic acid in order to accelerate the healing and complete resolution of the lesions. It is essential to make an early diagnosis to prevent unnecessary diagnostic and treatment procedures.
