Apocrine hidrocystomas arise from the proliferation of apocrine glands and are generally less than 1 cm in diameter . The pathogenesis of these tumors is not entirely known, but they tend to appear during adulthood, grow slowly, and persist indefinitely . Apocrine hidrocys-tomas are commonly found on the head, eyelids and neck . They are also been reported at oth-er sites, including axillae, areola of the nipple, periumbilical, anal, and genital areas .
