This is a 3 tiered site with Home as a single chapter on the first tier. On the second tier, there are 2 textual chapters. On the third tier, there are three pictorial chapters.
The first (level 1) cluster of black, primary navigation bars in the MASTERBORDER to the left provides access to all the chapters, including textual chapters at tiers 1 & 2 and pictorials at tier 3.
The second cluster of secondary bars (each identified by a black sphere) provides access to sections representing a variety of melanocytic lesions and a hodge-podge of skin lesions.
Black spheres identify secondary bars (i.e., the bars of the first cluster to the left at the end of the page). Two of these secondary bars provide access to web sites: 1.) melanocytic neoplasia with emphasis on a borderland, and 2.) the histology of inflammation of the skin.
The next cluster (black spheres) provides access to a fanciful discussion of melanocytic neoplasia (the Whithers 1, 2 & 3), and a discussion of desmoplastic melanoma.
The cluster to the right at the end of the page (black primary bars) provides access to the chapters of this section.
