Intermittent chronic telogen effluvium with an unusual dermoscopic finding following <scp>COVID</scp>‐19

Hair shaft defects, which are the result of both congenital and acquired pathologies, are usually accompanied by a violation of their physical characteristics and a change in appearance. Hair becomes dull, dry, not elastic, poorly styled, broken. Determining the presence of hair fragility formed the basis for the classification of heterogeneous abnormalities of the hair shaft and their division into two groups. The similarity of clinical symptoms and the impossibility of visual verification of the diagnosis dictate the need for additional research methods (dermatoscopy, microscopy, histology), the results of which will help to correctly diagnose. Knowledge of the nuances of the clinical picture, the main dermatoscopic and microscopic markers, the distinctive features of the course of various anomalies of the hair rods expands the capabilities of practicing trichologists, cosmetologists, dermatovenerologists and doctors of other specialties in the field of diagnosis, therapy and prevention of structural hair changes. The literature review presents the main clinical, dermatoscopic, microscopic and histological signs of various disorders of hair shafts.

Telogen effluvium post-COVID-19 is a condition characterized by the diffuse and reversible loss of scalp hair in the period following infection with SARS-CoV-2, and it is currently the second cause of alopecia in women. In the context of the COVID-19 infection, intense psychological stress contributes to alopecia appearance, along with systemic inflammation, autoimmune reactions, oxidative stress, and virally induced hypoxia. Cytokines with proinflammatory action and vasoactive substances negatively modulate the metabolism of some molecules, such as proteoglycans, involved in the hair follicle’s growth cycle. Studies show that a large percentage of hairs will suddenly enter the catagen phase during a moderate to severe COVID-19 infection. In the present paper, we update the data from the literature with a clinical example. Our case highlighted that the telogen effluvium after infections with SARS-CoV-2 is reversible with appropriate dermatological treatment. For therapeutic success, informing the patient about this pathology’s self-limited and reversible character is essential to reduce the emotional stress that may aggravate the disease.

A pandemia de Covid-19, causada pelo SARS-CoV-2, gerou complicações sistêmicas, incluindo a chamada "Covid longa". Relatos atípicos de queda de cabelo após infecções despertaram preocupações sobre o eflúvio telógeno e a alopecia areata na população acometida. Este estudo qualitativo e descritivo buscou aprofundar a compreensão da relação entre Covid-19, eflúvio telógeno agudo e alopecia areata, utilizando uma revisão integrativa realizada nas bases de dados BVS e Pubmed. Das 134 referências encontradas, 9 foram selecionadas após leitura crítica como principais resultados. Examinamos a relação entre a perda capilar pós-Covid-19, destacando fatores imunológicos e psicológicos. A relação entre Covid-19 e alopecia areata foi evidenciada, com destaque para o potencial desencadeador do vírus. A prevalência notável de afecções dermatológicas, especialmente o eflúvio telógeno, ressalta a necessidade de uma abordagem abrangente no tratamento. Concluímos destacando a importância de uma compreensão holística no tratamento pós-Covid-19, considerando aspectos fisiopatológicos e impactos psicológicos. A compreensão dos fatores imunológicos, psicológicos e do ciclo capilar orienta estratégias terapêuticas eficazes, proporcionando suporte emocional aos afetados.
