What is already known on this topic?The incidence of Endogenous Cushing's syndrome is 0.7-2.4 per million people per year with only 10 percent of cases occur in children and adolescents. Ectopic ACTH syndrome (EAS) accounts for 10 percent of cases of CS in adults but is it is a very rare condition in the paediatric population. Furthermore, the bronchial carcinoid causing Cushing's syndrome is extremely rare with only a few cases reported in literature and very less is known about its response to the treatment.
What this study adds?The rarity of disease necessitates the accumulation of data of each case to understand the clinical behaviour and the response achieved by appropriate management and strict follow up. This paper presents the current state of knowledge about Cushing's syndrome due to bronchial carcinoid in paediatric patients and includes the clinical presentation, pathophysiology, approach to diagnose and treat this rare condition and its clinical outcome. The illustration of imaging, pathological slides and clinical photographs also contributes to better understanding of these aspects of disease.
AbstractIntroduction-Cushing's syndrome (CS) is rare in childhood and adolescence. The most common cause for CS in children is exogenous administration of glucocorticoids in the form u n c o r r e c t e d p r o o f of topical, inhaled or oral corticosteroids. Endogenous causes can be classified into adrenocorticotropic hormone (ACTH) independent and ACTH dependent causes. Material and methods-The English literature was searched from 2019 to oldest via PubMed, Google and Google scholar using keywords; "Ectopic ACTH Syndrome in children", "Bronchial carcinoid in children" and "Cushing's Syndrome in children. The patients of Bronchial carcinoids causing Ectopic ACTH syndrome (EAS) and reviewed their variables like age, sex, type of carcinoid, investigations, surgery, recurrences and outcome. Results-We found 14 cases of pediatric bronchial carcinoid producing ACTH in literature with mean age of 15.8 years and female preponderance. Most of the patients had right lung lesion and typical carcinoid in histology. We also describe our experience of managing a 12 year old, female, who presented to us with features of Cushing's syndrome and found to have ectopic ACTH secreting bronchial carcinoid, which was resected surgically. Conclusion-Bronchial carcinoid is extremely rare in children and only 4% of them are associated with CS. The postoperative treatment of CS is challenging with high prevalence of hypertension, increased BMI and visceral fat mass, impaired cognitive functions and decreased quality of life. Our patient was managed successfully by multidisciplinary approach and has recovered from hypertension and Cushing's habitus. A careful follow up is indispensable to monitor recurrence of carcinoid and complete remission of CS.
