Value of CD10 expression in differentiating cutaneous basal from squamous cell carcinomas and basal cell carcinoma from trichoepithelioma

ABSTRACT

Background: In addition to the well-defined histological criteria for squamous cell carcinoma [SCC] and basal cell carcinoma [BCC], immunohistochemical techniques can be used in difficult cases for their differentiation. As differential diagnosis between trichoepithelioma [TE] and BCC is sometimes difficult for the clinician and the pathologist, CD10 may be a useful marker for definite diagnosis. We aimed to evaluate the usefulness of this marker in the differentiation between SCC and BCC and also in the differentiation between BCC and TE
