My Mood: Points: 1,317,367.96 Bank: 0.00 Total Points: 1,317,367.96 | Also, not all 'excessive hair growth' is hirsutism: Quote:
Two types of excessive hair disorders exist and must be distinguished. Hypertrichosis is non–androgen-related pattern of excessive hair growth that may involve vellus, terminal, or lanugo type hair. Hypertrichosis can accompany certain genetic syndromes, or it can be induced secondarily by exogenous medications, most notably phenytoin, minoxidil, cyclosporine, diazoxide, corticosteroids, phenytoin (Dilantin), streptomycin, hexachlorobenzene, penicillamine, heavy metals, sodium tetradecyl sulfate, acetazolamide, and interferon. Hirsutism commonly occurs in women and presents as androgen-induced male-pattern hair growth of the terminal type. Hirsutism may have a congenital or exogenous origin. More common causes of hirsutism include polycystic ovary syndrome (PCOS), idiopathic hirsutism, hyperprolactinemia, hyperthecosis, and medications (eg, danazol, androgenic oral contraceptives). Less common causes of hirsutism include congenital adrenal hyperplasia, ovarian tumors, Sertoli-Leydig cell tumors, granulosa–thecal cell tumors, other tumors that stimulate the ovarian stroma, adrenal tumors, Cushing disease, tumors of the adrenal cortex, and severe insulin-resistance syndromes.
