The cells are embedded within a myxoid stroma. Nests are separated by varying amounts of collagen.
Due to the large amount of myxoid stroma separating the cells, the tumor cells are said to display a random growth pattern.
The histologic features of myxoid neurothekeoma are distinguishing enough that its diagnosis is usually not problematic.
The myxoid neurothekeoma displays a lobulated, nonencapsulated but well-circumscribed proliferation of spindled and epithelioid cells embedded within a myxoid stroma.
