Four disorders are considered in this chapter: two primary disorders of the apocrine glands, namely (1) apocrine bromhidrosis and (2) apocrine chromhidrosis; and two secondary disorders, (1) Fox–Fordyce disease and (2) hidradenitis suppurativa (acne inversa), in which apocrine glands become secondarily affected. 4,5 5α-Reductase type I is expressed in apocrine glands.
