Dermatosis neglecta is the name of a skin condition characterized by papules and
polygonal plaques, which are sometimes warty, brownish and hyperpigmented, adherent
and symmetric, though removable with ethyl or isopropyl alcohol. It occurs due to
inadequate skin cleansing causing accumulation of sebum, sweat, keratin and
impurities. Its occurrence, though little reported, is frequent. The main
differential diagnosis is the Terra fi rma-forme dermatosis. The treatment is simple,
with exfoliation, moisturizing and even rubbing of alcohol. Causes of negligence on
the patient’s side, which can range from hygiene carelessness to psychiatric
disorders, local hypersensitivity, limbs negligence or motor paralysis, should be
investigated. We illustrate the case of dermatosis neglecta in a 45-years old patient
admitted with pulmonary sepsis.
