Dermal duct tumor: a histochemical and electron microscopic study

CH Hu, AS Marques, RK Winkelmann - Archives of Dermatology, 1978 - jamanetwork.com
• The histochemical and electron microscopic findings in seven cases of dermal duct tumor
are described. All seven of the patients were elderly, and five were women. The tumors were
small flesh-colored or red papules located most often on the head and neck region. Intense
phosphorylase and moderate respiratory enzymes characterized the histochemical reaction
of the tumors. The following three types of tumor cells were recognized ultrastructurally:
clear, dark, and luminal. The tumor was principally composed of clear cell proliferation …
