Seborrheic dermatitis is a frequent skin disorder in infancy and adulthood. It also often occurs in patients with HIV or neurologic disorders like Parkinson disease or mood disorders. It is characterized by greasy, yellow flakes or scales in areas of high sebaceous gland activity like the scalp, face, chest and upper back. Additionally, erythema and itching can be present. The etiology and pathogenesis of seborrheic dermatitis is unknown; however, the focus lies on the involvement of Malassezia yeasts or fatty acid metabolites of Malassezia, on hormones and immunologic factors. The diagnosis is usually a clinical one, based on history and the appearance and site of lesions. The therapy consists mainly of antifungal agents, corticosteroids, immunomodulators, and keratolytics. Because of the chronicity of the illness with frequent relapses, a treatment strategy in which effectiveness and potential side effects are weighed should be used.

Seborrheic dermatitis is a chronic, recurring, cutaneous condition that causes erythema and flaking, sometimes appearing as macules or plaques with dry white or moist oily scales. In adults, it commonly occurs in areas with high concentrations of sebaceous glands. The face and scalp are the most frequently affected areas, and involvement of multiple sites is common. Dandruff is regarded as a mild noninflammatory form of seborrheic dermatitis. There is a high incidence of seborrheic dermatitis among persons with human immunodeficiency virus infection or Parkinson's disease. The cause of seborrheic dermatitis is not well understood, but appears to be related to the composition of the sebaceous gland secretions, the proliferation of Malessezia yeasts, and the host immune response. Treatment options for nonscalp and scalp seborrheic dermatitis include topical agents and shampoos containing antifungal agents, anti-inflammatory agents, keratolytic agents, and calcineurin inhibitors. Because multiple body sites are usually involved, the physician should examine all commonly affected areas. Patients should be made aware that seborrheic dermatitis is a chronic condition that will probably recur even after successful treatment.

Livedo reticularis is a spastic-anatomical condition of the small vessels which translates morphologically by a reticular pattern, interspersing cyanosis, pallor and erythema. The same can be congenital or acquired. Among the acquired, we highlight the physiological livedo reticularis and the idiopathic livedo by vasospasm; the latter configures the most common cause. The drug-induced type is less common. The drugs amantadine and norepinephrine are often implicated. Cyanosis is usually reversible if the causative factor is removed, however, with chronicity, the vessels may become permanently dilated and telangiectatic. We report a case of a patient diagnosed with Parkinson's disease with chronic livedo reticularis associated with the use of amantadine and improvement after discontinuation of the drug.
