Method: This is a single case study, qualitative, of a 16-year-old adolescent experiencing maternal cancer. We analyzed a semi-structured interview, based on a script conceptualized by the selected theoretical model. Data processing took place through content analysis. Authorization was obtained from the Research Ethics Committee TI 25/2020. Results: The analysis of the adolescent’s interview allowed identifying categories in agreement with the model variables. Psychosocial adjustment dimensions and stress response symptoms, such as academic performance and somatic symptoms, were recognized in the adolescent’s adjustment process. Nursing interventions will focus on education and support. Conclusion: The theoretical model contributed to assess the needs of adolescents experiencing parental cancer, allowing nursing interventions to be prescribed in classified language that consider moderating and mediating variables, promoting adjustment. The model proved to be suitable for future interventions for adolescents experiencing similar situations.engAdolescentNeoplasmsNursingModelsTheoreticalA case study of an adolescent according to A Model of Children’s Adjustment to Parental CancerEstudo de caso de um adolescente segundo o Modelo Teórico do Ajuste ao Cancro ParentalEstudio de caso de un adolescente según el Modelo Teórico de Ajuste al Cáncer Parentaljournal articlehttps://doi.org/10.1590/1980-220X-REEUSP-2022-0188en1980-220X1008159036099199
