Adrenocortical tumors (ACT) are rare in childhood. Determination of malignant potential is difficult. To assess the presentation, clinical behaviour, and histology of these tumors in our center, the records of nine patients with ACTs between 1989 and 2000 were analyzed. The age, sex, clinical presentation, investigations, treatment, follow-up data, and current status were determined. The pathological features were reanalyzed by our pathologist. The endocrine profile of the tumors was also retrieved from the records. There were two males and seven females; the median age at referral was 2.5 years. Two patients (one male, one female) presented with clinical features of Cushing's syndrome with hypertension. Four girls had features of Cushing's syndrome with associated virilization. One 11-year-old girl presented with hypertension, hypokalemia, and pseudoparalysis due to an aldosterone-secreting tumor. One girl presented with precocious pubic hair and clitoromegaly. One male had evidence of true precocious puberty. The endocrine profile was available in eight cases: cortisol levels were raised in four, testosterone in four, and aldosterone in one. One boy had pubertal levels of follicle-stimulating hormone and testosterone. Surgery was the only modality of therapy used. Histopathology showed capsular invasion in four patients and vascular invasion in two. The median tumor weight was 80 g (15-550 g) and the size ranged from 1.5 x 1.5 to 12 x 12 cm. Five patients are alive without tumor recurrence at a median follow-up time of 2 years. Tumor recurrence was seen in two patients, one with capsular rupture during surgery and another with a tumor weight of 16 g with associated capsular and vascular invasion. Atypical modes of presentation like pseudoparalysis must be kept in mind. Histologic criteria for malignancy in ACT are unreliable. Tumor weight may not always be accurate in predicting tumor behaviour. Complete surgical excision remains the only effective and potentially curative treatment.
