Input: Abstract: In summary, we present a 30-year follow-up of injected wax for the prevention of male-pattern baldness. Removal was precipitated by the presence of a fibroxanthoma of the scalp. No other scalp lesions were found, nor were there any manifestations of an autoimmune disease. The injected wax failed to prevent androgenic alopecia and created a remodeling of the outer table of the cortex of the skull.
