Neurothekeoma is a rare neoplasm assigned to the broad category of benign peripheral nerve sheath tumors. Its cell of origin is still unknown, but most ultrastructural and immunohistochemical studies have favoured the Schwann cell perineurium or fibroblast. Neurothekeoma most commonly presents in females, especially in the second and third decades of life. Typically it presents as an asymptomatic solitary, firm, flesh-coloured or hyperpigmented slow-growing papule or nodule that involves the skin and superficial subcutis. It usually involves the face, neck, arm or shoulder but can also involve extracutaneous sites. Neurothekeoma occurs in myxoid (classic), cellular and intermediate (mixed) variants. Here, we report a 45-year-old male patient presenting with a nodule on the nose that was found to be a myxoid variant of neurothekeoma. It was treated with a simple shave excision followed by removal of the lobulated deeper part by forceps. He had no recurrence after tthree years of follow-up. To the best of our knowledge, this is the first case of a myxoid neurothekeoma of the nose to be reported in the Middle East.
