Step 1: Understanding bone growth disorders.
Bone growth abnormalities are often caused by hormonal imbalances, especially growth hormone (GH) secretion.
Step 2: Role of growth hormone.
Excess secretion of GH in adults leads to abnormal enlargement of bones, particularly facial bones, hands, and feet.
Step 3: Definition of acromegaly.
Acromegaly is a condition caused by hypersecretion of GH after epiphyseal closure, resulting in enlargement of facial bones and extremities.
Step 4: Evaluating other options.
Cushing’s syndrome is due to cortisol excess, dwarfism is GH deficiency, and goiter is thyroid enlargement.
Step 5: Clinical reasoning.
Facial bone enlargement is a hallmark symptom of acromegaly, not other listed disorders.
Step 6: Final conclusion.
Thus, the correct answer is acromegaly.
