Pathologic examination revealed a cystic cavity lined by stratified squamous epithelium and filled with desquamated orthokeratinized material. The epithelial lining contained hair follicles and sebaceous glands. There were no postoperative complications, and the lesion has not recurred.
The diagnosis of midline nasal masses in children includes inflammatory or infectious lesions (subcutaneous abscess), facial trauma sequelae, benign neoplasm (eg, angioma, fibrous dysplasia, meningioma, and neurofibroma), malignant neoplasm (eg, teratoma, rhabdomyosarcoma, olfactory neuroblastoma, lymphoma, histiocytosis, and metastatic tumor), and congenital masses (eg, nasal dermoid cyst, epidermoid cyst, glioma, and encephalocele).1 The incidence of congenital midline masses has been reported to be 1 in every 20,000 to 40,000 births.2
