Source abstract
BACKGROUND: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy of the adrenal glands, characterized by a high potential for local invasion and metastasis. In pediatric patients, it often presents as a localized tumor with either benign or intermediate malignant potential. While ACC is considered rare in children, early diagnosis and intervention are critical for improving outcomes. This case report presents three children diagnosed with intermediate-potential malignant ACC, diagnosed at an early stage, and successfully treated with complete surgical resection. CASE DESCRIPTION: The first case involves a 2-month-old female neonate presenting with signs of Cushingoid syndrome and a 5.5 cm left-sided stage II ACC. The second case describes a 3-year-old male who exhibited peripheral signs of precocious puberty with a 7 cm androgen-secreting right-sided stage II ACC. The third case involves a 2.5-year-old boy who presented with a hypertensive crisis-related seizure, adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome, and peripheral precocious puberty due to a 3.5 cm right adrenal stage I ACC. All three patients underwent successful complete resection of their respective tumors, with no signs of locoregional invasion or distant metastasis. Postoperatively, there was a complete resolution of the endocrine manifestations, such as Cushingoid features and precocious puberty. All three children underwent successful complete tumor resection, resolution of the endocrine findings and no recurrences after up to 4 years of follow-up. CONCLUSIONS: This case report highlights the diverse clinical presentations of pediatric ACC, showcasing the various hormonal profiles and symptoms associated with the disease. It emphasizes the critical importance of early detection and complete surgical resection in improving patient outcomes. Although pediatric ACC is a rare and aggressive disease, these cases demonstrate that with appropriate intervention, favorable outcomes can be achieved, even in cases with intermediate malignant potential.
