Nodular trichoblastoma or basal cell carcinoma: A diagnostic dilemma of clinical significance

Nodular Trichoblastoma (TB) is a rare and benign adnexal tumor originating from rudimentary hair follicles. Adnexal neoplasms show complex clinical and histological features. A panel of immunohistochemical (IHC) markers helps in distinguishing tumors of follicular origin from other cutaneous tumors especially Basal cell carcinoma (BCC). We herein describe the histological and immunohistochemical features of TB which clinically and histologically mimiced BCC.
