Membranous type Basal Cell Adenoma (BCA).
🧨 Morphologically identical to cutaneous cylindroma, hence aka dermal analogue tumor.
🧨 This is a unique morphologic subtype that one should be aware of.

🧨 Because this particular subtype can be multifocal.
🧨 This can be associated with Brooke Spiegler syndrome, a rare AD disease caused by mutation of CYLD gene on chr 16.
🧨 This has a higher rate of local recurrence (25%) than other subtypes. 2/3
