The occurrence of metastatic basal cell carcinoma (MBCC) is extremely low, ranging from 0.0028 to 0.5%. We present a rare case report of MBCC in a 57‐year‐old Caucasian male with a known history of numerous nonmelanoma cutaneous neoplasms. The patient presented with a large ulcerated right axillary mass that recurred 2 months after an initial BCC was resected from the same site. An excisional biopsy of the recurrent mass and regional lymph nodes showed atypical basaloid cells with hyperchromatic nuclei, stromal retraction and rare squamous features in the soft tissue and lymph node. The tumor cells were bcl‐2 negative and positive for Ber‐EP4. The negative expression of bcl‐2 correlates with the aggressive nature of this tumor and Ber‐EP4 confirmed the diagnosis of BCC.
