CD44 and carcinoma: Previous studies on the colon found that CD44 pattern of staining was mainly membranous (Al-Maghrabi et al., 2012; Holah et al., 2017) and there was a highly significant difference between carcinoma cases and normal cases (p = 0.02) (Chai et al., 2013), which is in line with our findings with respect to CD44 expression.
