Morphometric characteristics of basal cell carcinoma peritumoral stroma varies among basal cell carcinoma subtypes

Table 2 Presence of immune reactions or elastosis in basal cell carcinomas.

Characteristic	Infiltrative¹ (n = 15)	Nodular¹ (n = 60)	Superificial¹ (n = 23)	P 1 (Infiltrative-Nodular)	P 2 (Infiltrative-Superficial)	P 3 (Nodular-Superficial)
Immune Reaction	4 (0.27)	18 (0.30)	12 (0.52)	1.0	0.32	0.14
Elastosis	8 (0.53)	12 (0.20)	6 (0.26)	0.0057	0.17	0.37

Chi-squared tests were used except where an individual cell had a value less than five in which case a Fisher's exact test was used
¹ Data are presented as totals and proportions
P 1 = p-value obtained for the difference between the median variable values between the infiltrative and nodular subtypes
P 2 = p-value obtained for the difference between the median variable values between the infiltrative and superficial subtypes
P 3 = p-value obtained for the difference between the median variable values between the nodular and superficial subtypes
