Reflectance confocal microscopy (RCM) is a noninvasive imaging technique that has been used to diagnose basal cell carcinoma (BCC). How accurate is RCM to predict whether a BCC is infiltrative or superficial?

The 2006 study {2} was inconclusive:

Limitations: The pigmented BCCs imaged in this study were predominantly nodular; a different set or additional criteria may be necessary for detection of infiltrative and metatypical BCCs.

The 2016 study {1} focused on superficial basal cell carcinoma (sBCC) but only looked at 3 cases.


  1. Understanding if RCM is a decent replacement for a biopsy to diagnose BCC.
  2. Superficial BCCs can be treated quite well with Imiquimod 5% cream (US brand: Aldara) but Imiquimod not doesn't work as well on infiltrative BCCs, which typically requires surgery (Mohs if cosmesis is important or old-fashioned excision).
