13. Sindrome de Cushing
Body Compartment/System Signs and Symptoms
Body fat Weight gain, central obesity, rounded face, fat pad
on back of neck ("buffalo hump")
Skin Facial plethora, thin and brittle skin, easy
bruising, broad and purple stretch
marks, acne, hirsutism
Bone Osteopenia, osteoporosis (vertebral fractures),
decreased linear growth in children
Muscle Weakness, proximal myopathy (prominent atrophy
of gluteal and upper leg muscles)
Cardiovascular system Hypertension, hypokalemia, edema, atherosclerosis
Metabolism Glucose intolerance/diabetes, dyslipidemia
Reproductive system Decreased libido, in women amenorrhea (due to
cortisol-mediated inhibition of gonadotropin
release)
Central nervous system Irritability, emotional lability, depression,
sometimes cognitive defects, in severe cases,
paranoid psychosis
Blood and immune system Increased susceptibility to infections, increased
white blood cell count, eosinopenia,
hypercoagulation with increased risk of deep vein
thrombosis and pulmonary embolism
