Overview
Signs and Symptoms
Adrenocortical carcinoma may present differently in children and adults. Most tumors in children are functional, and virilization is by far the most common presenting symptom, followed by Cushing's syndrome and precocious puberty. Among adults presenting with hormonal syndromes, Cushing's syndrome alone is most common, followed by mixed Cushing's and virilization (glucocorticoid and androgen overproduction). Feminization and Conn syndrome (mineralcorticoid excess) occur in less than 10% of cases. Rarely, pheochromocytoma-like hypersecretion of catecholamines has been reported in adrenocortical cancers.[1] Non-functional tumors (about 40%, authorities vary) usually present with abdominal or flank pain, or they may be asymptomatic and detected incidentally.
All patients with suspected adrenocortical carcinoma should be carefully evaluated for signs and symptoms of hormonal syndromes. For:
- Cushing's syndrome (glucocorticoid excess) these include weight gain, muscle wasting, purple lines on the abdomen, a fatty "buffalo hump" on the neck, a "moonlike" face, and thinning, fragile skin.
- Virilism (androgen excess) is most obvious in women, and may produce excess facial and body hair, acne, enlargement of the clitoris, deepening of the voice, coarsening of facial features, and cessation of menstruation.
- Conn syndrome (mineralcorticoid excess) is marked by high blood pressure, which can result in headache, and hypokalemia (low serum potassium), which can produce muscle weakness, confusion, and palpitations. Low plasma renin activity, and high serum aldosterone.
- Feminization (estrogen excess) is most readily noted in men, and includes breast enlargement, decreased libido and impotence.[2]
