Patients usually present with a slowly enlarging asymptomatic swelling. Diagnosis is usually made in the early stages because of the esthetic effects. Histologically, the lesion is lined with non-keratinized squamous epithelium or, more frequently, pseudostratified columnar epithelium with goblet cells. These cysts are most often diagnosed in the fourth decade of life. However, we report a case of nasolabial cyst in an 80-year-old woman, and discuss the diagnosis, differential diagnosis, and treatment with reference to the literature.展开更多

Hypoglossal schwannomas usually occur between the third and fifth decades of life, with no sex predilection, commonly presenting as a painless, slow-growing, and lateral neck mass. The best treatment is complete surgical excision with preservation of the neural pathway, if possible. In fact, since these tumors are almost always benign, a conservative surgical approach is emphasized by most authors. We report a case of a large schwannoma of hypoglossal nerve origin in the upper neck in a 31-year-old male. Magnetic resonance imaging of the area demonstrated a 43 × 39 × 36 mm well-circumscribed mass with high and nonhomogeneous signal intensity on the right side of the upper neck. The lesion was successfully treated by extirpation, with no recurrence. The extracranial hypoglossal nerve sheath was as the origin of this tumor because the patient experienced remarkable disturbance of tongue motility after surgery.展开更多
