Case 1: The micronodular variant demonstrates discrete nodules the dermis. The surrounding stroma can often be quite desmoplastic. The small nodules tend to invade deeper into the dermis and even into the subcutis.

Case 2: Although the exact size of a micronodule has not been agreed upon, it is clear that this variant is composed of small nodules of basaloid cells rather than the larger nodules of the nodular variant.

Micronodular BCC is similar to nodular BCC, however, the nests are smaller and clinically, this variant appears as a plaque with poorly demarcated borders. It may penetrate more deeply into the dermis or subcutis and has a higher rate of local recurrence. Thus, micronodular BCC is considered to be in between the nodular and aggressive subtypes in terms of behavior (Crowson).
