The role of contact endoscopy in screening for premalignant laryngeal lesions: A study of 141 patients

May 8, 2014  |  Marisa Klancnik, MD; Ivo Gluncic, MD, PhD; Drasko Cikojevic, MD, PhD

Abstract

At their earliest stage, pathologic lesions of the laryngeal epithelium are macroscopically invisible. Ideally, these lesions should be detected before their clinical manifestations appear so that prompt management can be initiated. However, most diagnostic modalities are...

Abstract

We describe the use of an endoscopic modified Lothrop approach for clearance of an extensive sinonasal-type hemangiopericytoma of the nasal cavity and paranasal sinuses with bilateral frontal sinus involvement in a 44-year-old woman. The modified Lothrop approach is...

Cervical sympathetic chain paraganglioma: A report of 2 cases and a literature review

Abstract

We review 2 cases of surgically and pathologically confirmed paraganglioma of the cervical sympathetic chain. Both patients-a 46-year-old man and a 33-year-old woman-were treated surgically. Intraoperatively, both tumors were found to be hypervascular and arising from the...

Abstract

Inflammatory pseudotumor (IPT) is a rare, locally aggressive, benign neoplasm of unknown etiology. It is uncommon in the head and neck region, particularly in the paranasal sinuses. We present an unusual case of IPT of the maxillary sinus and orbit in a 27-year-old woman who...

Abstract

Granular cell tumor (GCT) is an uncommon, primarily benign lesion. We describe 2 cases of GCT. Patient 1 was a 38-year-old man who presented with a reddish, vegetative lesion that involved the posterior third of the left true vocal fold. Patient 2 was an 18-year-old girl who...

Organized hematoma of the maxillary sinus: A clinicopathologic study of 5 cases

February 12, 2014  |  Hidenori Yokoi, MD, PhD; Atsushi Arakawa, MD, PhD; Fumihiko Matsumoto, MD, PhD; Naoko Yokoi, MD, PhD; Katsuhisa Ikeda, MD, PhD; and Naoyuki Kohno, MD, PhD

Abstract

Organized hematoma of the maxillary sinus is rare. Its pathogenesis is still not clear, and it appears to have multiple causes. We report the clinical, clinicopathologic, and immunohistochemical findings in 5 patients-3 men and 2 women, aged 19 to 68 years (mean: 40.2)-with...

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...

Transglottic laryngeal paraganglioma: A rare location for this tumor

December 20, 2013  |  Secil Arslanoglu, MD; M. Zafer Uguz, MD; Demet Etit, MD; Murat Ermete, MD

Abstract

Laryngeal paragangliomas are rare neoplasms that originate in the neural crest cells of the laryngeal paraganglia. Although the vast majority of these tumors are benign, they exhibit different types of biologic behavior that require different treatment modalities. Therefore,...

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

Abstract

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...
