Workup

  • Because AI has been linked to a variety of conditions, the workup of a patient presenting with this finding can be complex.[ncbi.nlm.nih.gov]

Treatment

  • The prognosis and treatment of generalized Kaposi's sarcoma is discussed.[ncbi.nlm.nih.gov]

Prognosis

  • Prognosis The prognosis for hereditary ichthyosis vulgaris is excellent. Many patients experience improvement of symptoms with age. The prognosis for acquired ichthyosis vulgaris depends on the severity of the underlying systemic disease.[emedicine.medscape.com]

Etiology

  • Ichthyoses comprise a large group of skin scaling disorders with diverse etiologies. The stereotypic pathophysiology is epidermal hyperplasia and abnormal desquamation, leading to visible accumulation of squames (scales) on the skin’s surface.[ansa.it]
  • A 2018 study identified 607 atopic dermatitis genes and 193 ichthyosis vulgaris ones as differentially expressed when these atopic or ichthyosis vulgaris patients were compared with healthy donors. [20] Etiology Hereditary ichthyosis vulgaris is an autosomal[emedicine.medscape.com]

Pathophysiology

  • Disruption of epidermal growth pathways through inhibition of various receptor tyrosine kinases by ponatinib may offer insights into the pathophysiologic mechanisms behind acquired ichthyosis.[ncbi.nlm.nih.gov]
  • Other Medscape Drugs & Diseases articles on ichthyosis include the following: Pathophysiology Ichthyosis vulgaris is classified as a retention hyperkeratosis.[emedicine.medscape.com]
  • The pathophysiological mechanisms responsible for paraneoplastic ichthyosis remain unclear. Ichthyosis occurs when there is a disruption in the process of cornification, which is complex and involves multiple enzymes.[karger.com]
  • The stereotypic pathophysiology is epidermal hyperplasia and abnormal desquamation, leading to visible accumulation of squames (scales) on the skin’s surface.[ansa.it]

  • This helps prevent dryness, scaling, cracking and build-up of skin. The skin affected by ichthyosis is treated by hydration with alpha-hydroxy acid lotions such as ammonium lactate. People with acquired ichthyosis have normal lifespan.[streetdirectory.com]
  • The main goal of the treatment is to hydrate the skin and to prevent complications such as infection. Use of soap-free cleansers and regular moisturisers are essential.[dermcoll.edu.au]
  • There are no guidelines for preventing the development of ichthyosis.[uvahealth.com]
