Encyclopedia entry (1928–1936)
ADENOMA SUDORIFERUM (hydradenoma eruptivum, syringo-cystadenoma; epithelioma benignum cysticum; lymphangioma tuberosum multiplex; syringoma and others), a rare dermatosis clinically characterized by the appearance of multiple dense nodules, ranging in size from a pinhead to a pea, in color from normal skin to brownish. Usually they resemble syphilitic papules, but do not peel, are monomorphic, and are persistent. Localization: neck, chest, lower eyelids. Histologically: in the corium, cords of cylindrical or polygonal epithelium, sometimes with cysts. The diagnosis is sometimes established only by biopsy, since clinically there may be complete similarity with adenoma sebaceum. Treatment: electrolysis, galvanocautery.
