Diagnostic Considerations

Also consider the following:

  • Squamous cell carcinoma with microcystic adnexal carcinoma (MAC)–like features
  • Adenosquamous carcinoma
  • Eccrine epithelioma
  • Squamoid eccrine ductal carcinoma
  • Trichoadenoma
  • Cutaneous metastases of breast carcinoma
  • Cutaneous metastases of microcystic squamous cell carcinoma of the lung [47]
  • Other metastatic adenocarcinomas
  • Sweat duct proliferation associated with atrophoderma vermiculata [48]
  • Sclerosing microcystic adenocarcinoma/MAC-like carcinomas arising in the mucosal head and neck (some consider this entity as MAC on mucosal surfaces) [9]
