Acta Derm Venereol 2023; 103:adv12404. [PMID: 37615526 PMCID: PMC10464823 DOI: 10.2340/actadv.v103.12404] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 07/11/2023] [Indexed: 08/25/2023] Open
Abstract
This retrospective registry-based cohort study aimed to estimate the incidence and prevalence of genodermatoses in the Swedish population and to analyse associated healthcare usage. Patients diagnosed with genodermatoses were identified from the patient registry of Sahlgrenska University Hospital (Gothenburg, Sweden) between 2016 and 2020. Clinical data from medical records were used to verify diagnoses recorded in the National Patient Registry (NPR). The NPR was then searched for International Classification of Diseases, Tenth Revision (ICD-10) codes Q80-82 and Q84 from 2001 to 2020. The local cohort included 298 patients with 36 unique genodermatosis diagnoses. Verification of these diagnoses in the NPR showed positive predictive values of over 90%. The NPR search yielded 13,318 patients with 73 unique diagnoses, including ichthyoses (n = 3,341; 25%), porokeratosis (n = 2,277; 17%), palmoplantar keratodermas (n = 1,754; 13%), the epidermolysis bullosa group (n = 1011; 7%); Darier disease (n = 770; 6%), Hailey-Hailey disease (n = 477; 4%) and Gorlin syndrome (n = 402; 3%). The incidence and prevalence of each diagnosis were calculated based on the nationwide cohort and are reported. A total of 149,538 outpatient visits were registered, a mean of 4.6 visits per patient. This study provides a valuable resource for the epidemiology of genodermatoses by reporting on the incidence and prevalence of 73 different genodermatoses.

Ichthyoses-A Clinical and Pathological Spectrum from Heterogeneous Cornification Disorders to Inflammation. Dermatopathology (Basel) 2021; 8:107-123. [PMID: 34066992 PMCID: PMC8161842 DOI: 10.3390/dermatopathology8020017] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 04/27/2021] [Accepted: 04/28/2021] [Indexed: 11/22/2022] Open
Abstract
Ichthyoses are inborn keratinization disorders affecting the skin only (non-syndromic) or are associated with diseases of internal organs (syndromic). In newborns, they can be life-threatening. The identification of the gene defects resulted in reclassification and a better understanding of the pathophysiology. Histopathologic patterns include orthohyperkeratosis with a reduced or well-developed stratum granulosum, hyperkeratosis with ortho- and parakeratosis with preserved or prominent stratum granulosum, and epidermolytic ichthyosis. Another pattern features “perinuclear vacuoles and binucleated keratinocytes”, which is associated with keratin mutations. Some ichthyoses are histologically defined by psoriasis-like features, and distinct subtypes show follicular hyperkeratosis. In addition to histological and immunohistochemical methods, these patterns allow a better histopathologic diagnosis.

Abstract
Congenital ichthyosis includes a group of rare skin disorders known for tiles of hyperkeratotic skin resembling fish scales. With age, the hyperkeratosis generally becomes more concentrated around joints which increases impairment. Ichthyosis with confetti, also known as ichthyosis variegata or congenital reticular ichthyosiform erythroderma, is an extremely rare form of ichthyosis. It usually begins as non-bullous congenital ichthyosiform erythroderma with the expected scaling. However, with time patients develop widespread 'confetti-like' patches of healthy skin. The healthy skin reflects clonal expansion of 'normal' or reverted cells. Cell reversion has potential for future therapies using revertant stem cells. Controlling symptoms with emollients is the goal of treatment for ichthyosis since it has no cure.

[PMID: 21074957 DOI: 10.1016/j.braindev.2010.10.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2010] [Revised: 10/07/2010] [Accepted: 10/11/2010] [Indexed: 10/18/2022]
Abstract
We report a female patient with ichthyosis, epilepsy, mental retardation, hypergonadotrophic hypogonadism, polyneuropathy, and cranial dysmorphisms. This clinical picture may satisfy the main diagnostic criteria that characterize Rud syndrome (RS), a rare neurocutaneous disease. The patient underwent extensive clinical evaluation, neurophysiological studies (wakefulness and sleep EEG, EMG), dermatological and endocrinological evaluation and neuroimaging study (3 Tesla brain MRI). Interestingly, brain MRI unveiled a malformation of cortical development, never reported previously in RS. Although seizure semiology and EEG features could not provide clear cut information suggesting a focal onset, the role of this MRI finding in the genesis of the epileptic seizures cannot be ruled out. The finding of a focal cortical dysplasia in RS might be related to genetic abnormalities affecting the development of both epidermis and neural structures with the same embryological origin.
