Fig. 16  [Fig.3] A vertically oriented girondolelike arrangement of basaloid proliferations is displayed around a follicular axis. Inset, the lacelike basaloid proliferation, arising from the apparent external root sheath, has a hyaline basement membrane (frozen section, hematoxylin-eosin, x60; inset, x300).

Message

 
Folliculocentric basaloid proliferations seen in patients undergoing Mohs" micrographic surgery for basal-cell carcinoma represent complex growths of bulge epithelium. Folliculocentric basaloid proliferation is characterized histologically by a girondolelike arrangement of basaloid cells.
 

Critique

 
The insert in one of the photomicrographs shows sebocytes within the latticelike arrangement of epithelial cells, an indication that folliculocentric basaloid proliferation is a hyperplasia of mantle, rather than bulge, epithelium. The mantle is the anlage of sebaecous glands and ducts.
