Abstract

Objectives Cushing's disease (CD) is a diagnostic and therapeutic challenge, especially in pediatric patients. CD, primarily caused by adrenocorticotropic hormone-secreting pituitary adenomas, manifests typically with growth retardation and weight gain. There are no published guidelines for pediatric patients.Case presentation We report three pediatric patients diagnosed with CD in a Portuguese tertiary hospital. All patients presented with hypercortisolism features. All patients underwent transsphenoidal pituitary surgery (TSS) as a first-choice treatment; however, it was unsuccessful in one patient and the other patients experienced recurrence. Patients were submitted to different approaches so basal serum cortisol levels could be achieved. Two of three patients achieved remission.Conclusions TSS remains the first-line treatment yet challenging due to microadenomas and technical complexities. Medical therapy with agents like metyrapone or ketoconazole, pituitary radiotherapy, or bilateral adrenalectomy are, usually, second-line interventions, unless there is a contraindication to surgery. Our findings support the finding that a shorter hypothalamic-pituitary-adrenal axis recovery time increases the risk of recurrence of CD. Our cases illustrate the intricate management and variable outcomes of pediatric CD, underscoring the importance of multidisciplinary care and continuous surveillance.
