Scoring Method to Assess the Degree of Collagen Deposition or CD34 Immunostaining

Score	Degree of CD34 Immunostaining	Degree of Collagen Deposition
0	No CD34 immunostaining	No collagen deposition
1	Occasional focal areas of CD34 immunostaining	Occasional focal areas of collagen deposition
2	Regular focal areas of CD34 immunostaining	Regular focal areas of collagen deposition
3	Frequent focal areas of CD34 immunostaining	Frequent focal areas of collagen deposition
4	Diffuse CD34 immunostaining	Diffuse area of collagen deposition
