Clumped perinuclear BAP1 expression is a frequent finding in sporadic epithelioid Spitz tumors.

abstract：BACKGROUND:CD44 is a membrane glycoprotein and the major cell-surface receptor of hyaluronate (HA). Lack of CD44 expression in mouse epidermis leads to an abnormal HA accumulation in the dermis, indicating an important role of CD44 in local HA metabolism. Decrease of epidermal CD44 expression in patients of lichen scle...
