Trichilemmal carcinoma: A rare cutaneous adnexal tumour

Trichilemmal carcinoma is a rare neoplasm arising from outer root sheath of hair follicle on sun exposed areas, the diagnosis of which is predominantly confirmed on histological features as it resembles other malignant skin tumours. Immunohistochemistry helps in identifying the cell of origin. As the tumor is of low malignant potential and has indolent clinical course, the treatment is exclusively surgical. We report a case of 62-years-old healthy woman who presented with a painless nodule on scalp growing rapidly for the past 4 months. Wide surgical excision was conducted and the patient was followed up for one year with no signs of recurrence. Therefore, we emphasize that early detection and initiation of treatment with careful follow up is the only requirement needed to manage this tumour.
