Secretory carcinoma. These multinodular tumors present in dermis and superficial subcutaneous adipose tissue (a). They are composed of uniform epithelioid cells with vesicular nuclei and small nucleoli with florid luminal differentiation giving rise to a microcystic architecture. Also note the intraluminal pink colloid secretions (b). The tumor cells express cytokeratin AE1/3 (c) and S100 (d). Courtesy of Prof. B. Luzar, University of Ljubljana
