Squamous cell carcinoma (SCC) is the second most common non-melanoma skin cancer and accounts for 90% of head and neck malignancies. Intracranial metastases of SCC are extremely rare. We are reporting a case of 55-year-old female with history of recurrent swelling over right side of forehead which was previously reported as cylindroma. CT scan of head revealed irregular lytic areas in right frontal bone suggestive of erosion. There were multiple small, rim enhancing lesions in bilateral parietal regions. Clinically it was diagnosed as malignant adnexal tumour. Wide excision of the lesion revealed features of invasive basaloid squamous cell carcinoma, probably a malignant transformation of the pre-existing cylindroma.
