Facial nerve schwannoma mimicking chronic suppurative otitis media: A case report.

Rationale: Facial nerve schwannoma (FNS) is a rare slow-growing nerve sheath tumor derived from Schwann cells. FNS with normal facial nerve function may sometimes be misdiagnosed as otitis media because of similar ontological symptoms such as purulence, tympanic membrane damage, and hearing loss.

Patient Concerns: A 68-year-old woman was referred to our department because of otorrhea and hearing loss in the right ear for 20 years.

Sarcomatoid carcinoma involving the nasal cavity and paranasal sinus: a rare and highly progressive tumor.

Sarcomatoid carcinoma of nasal cavity and paranasal sinuses is an extremely rare malignant neoplasm. We report a case of sarcomatoid carcinoma arising in the left-side nasal cavity and paranasal sinuses in a 65-year-old man who was hospitalized for left-side nasal epistaxis, odor sensation. Histopathologic examination revealed the tumor was composed of pleomorphic spindle and round cells with frequent mitosis, and no carcinomatous component was recognized.
