Description

      Trichilemmal carcinoma (TC) is a rare malignant adnexal neoplasm with outer roots heath differentiation was first described by Headington. TC is commonly located on the scalp, forehead and neck, trunk or the upper extremities. Nevertheless an adverse outcome may occur with ganglion metastases and rarely haematogenous. Differential diagnosis is very important to distinguish it from the other malignant tumors, Although dermoscopic examination is very important to perform while considering the differential diagnosis of skin cancers, it is sometimes difficult to distinguish adnexal tumors from non melanoma skin cancers as in our case. We report a case of trichilemmal carcinoma in the inguinal region, which might have been diagnosed as a squamous cell carcinoma but Dermoscopic view of the tumor suggested a trichilemmal carcinoma, confirmed by histopathological examination.
