Sarcoidosis is a systemic inflammatory disease that can affect virtually every organ system, leading to a wide variety of clinical manifestations. Central nervous system involvement producing neurologic symptoms can occur in patients with sarcoidosis, yet rarely are these...

The endoscopic transnasal paraseptal approach to a sphenoid sinus osteoma: Case report and literature review

December 20, 2013  |  Frank Rikki Canevari, MD; Georgios Giourgos, MD; Andrea Pistochini, MD


Osteomas are the most common benign tumors of the nose and paranasal sinuses. Their symptoms, which are nonspecific, occur as the result of a blocked nasal airflow or, in some rare cases, the involvement of nearby structures. Isolated sphenoid sinus osteomas are very rare, as...

A case and a series of published cases of esthesioneuroblastoma (ENB) in which long-standing paraneoplastic SIADH had preceded ENB diagnosis

October 24, 2013  |  Uri Gabbay, MD, MPH; Leonor Leider-Trejo, MD; Gideon Marshak, MD; Merav Gabbay, MD; and Dan M. Fliss, MD


Esthesioneuroblastoma (ENB) is a rare tumor of the olfactory mucosa. We treated a 50-year-old man with an ENB in the right ethmoid sinus who had been diagnosed 16 years earlier with syndrome of inappropriate antidiuretic hormone secretion (SIADH) of unknown cause. When the ENB...

Mummified leiomyoma of the midline anterior neck: Case report and literature review

August 22, 2013  |  Jacob Minor, MD; Mona Rizeq, MD; and Todd Wine, MD


Leiomyomas are benign smooth-muscle tumors that have only rarely been reported in the head and neck. Extensive calcification (mummification) is occasionally seen in deep somatic soft-tissue leiomyomas, which represent a rare subtype. We describe a case of mummified leiomyoma of...

Peripheral osteomas of the hard palate are relatively rare. Two cases of osteoma of the hard palate are reported, along with a review of the literature.

Giant cell tumor of the larynx: A case of malignant sarcomatous transformation

June 12, 2013  |  Richard J. Vivero, MD; Sandeep P. Dave, MD; Carmen R. Gomez, MD; and Donald T. Weed, MD


We report what is to the best of our knowledge the first case of malignant transformation of a giant cell tumor of the larynx. The patient, a 34-year-old man, presented to our tertiary care university teaching hospital where he underwent hemilaryngopharyngectomy with radial...

Spindle cell lipoma of the larynx

June 12, 2013  |  Antonio D'Antonio, MD, PhD; Giampiero Mottola, MD; Alessia Caleo, MD; Maria Addesso, MD; and Amedeo Boscaino, MD


Among the primary mesenchymal tumors of the hypopharynx and larynx, lipomas are rare. Macroscopically, they often resemble a retention cyst or laryngeal nodule. Spindle cell lipomas (SCLs) are an uncommon variant of lipoma. SCLs are extremely rare in the larynx; as far as we...

Primary pleural malignant mesothelioma with delayed metastasis to the piriform sinus: Report of a case

June 12, 2013  |  Umit Taskin, MD; Ozgur Yigit, MD; Mithat Aricigil, MD; and Gulben Huq, MD


Piriform sinus tumors are uncommon and silent lesions. Their prognosis is poor because these tumors are usually not detected until they have reached an advanced stage. Almost all piriform sinus cancers are primary squamous cell carcinomas; other primary and metastatic tumors of...

Solitary extramedullary plasmacytoma of the nasal tract: An unusual cause of epistaxis

Solitary extramedullary plasmacytoma is a rare hematologic malignancy with nonspecific clinical symptoms and imaging findings. We present a case of this entity that arose in the nasal tract of a 50-year-old man. The tumor was removed surgically, and the patient showed no...

A case of glomangiopericytoma involving the orbital wall

April 18, 2013  |  Eun Sun Jung, MD, PhD; Suk-Woo Yang, MD, PhD; Ji-Hong Kim, MD; Soo Whan Kim, MD, PhD


Sinonasal type hemangiopericytomas are very rare tumors, and are often called glomangiopericytoma. They are believed to be derived from perivascular modified smooth muscle cells. Their origin is similar to glomus tumors but some distinct differences exist. Glomangiopericytomas...
