Fig. 2. — CD99 expression in the normal adult sweat glands and sebaceous glands. (A) In apocrine glands, flattened lining cells are immunonegative for CD99 (left). Meanwhile, tall cells in apocrine glands express CD99 (right). (B) Inner small cells of eccrine glands express CD99 in opposition to outer large cells (arrow). Apicoluminal surface of the eccrine glands are immunonegative for CD99. (C) Two layers of excretory ductal cells are immunopositive for CD99. (D) In sebaceous glands, outer basal cells express CD99. However, mature sebocytes do not express CD99.
