Any large basaloid tumor presenting in the dermis, including poorly differentiated adnexal carcinoma or metastatic carcinoma, has the potential to be mistaken for BCC if attention is not given to the clinical presentation, high-grade cytologic atypia, and absence of hallmark features of BCC.
Cutaneous adnexal carcinoma arising within a solitary cylindroma-spiradenoma.
Histopathologically, the deep and plaque types can be mistaken for microcystic adnexal carcinoma.
Based on the results of the database search, 27 cases were retrieved from the University of Pittsburgh Medical Center archives for the study: 12 cases of ductal CMBC (44%), which included 11 cases with morphologies not otherwise specified and 1 case of basal phenotype; 11 cases of SGC (41%), which included 5 cases of EC, 3 cases of porocarcinoma (PC), and 3 cases of microcystic adnexal carcinoma (MAC); and 4 additional, randomly selected cases (15%), which included 2 primary cutaneous adnexal benign neoplasms (a poroma and an apocrine adenoma) and 2 cases of PBC.
5) The clearly malignant features of this neoplasm required diagnosis as syringocystadenocarcinoma papilliferum, a rare, malignant, primary cutaneous adnexal carcinoma.

Ivan et al (25) extended the analysis of p63 to include metastases from adnexal carcinomas and found that 91% of PCANs were strongly marked with p63 and, excluding apocrine and mucinous carcinoma, their metastases labeled similarly.
