March 1, 2012     Joseph P. Mirante, MD, FACS, Dewey A. Christmas, MD, and Eiji Yanagisawa, MD, FACS

A patient presented with what appeared to be a defect in the left medial wall of the maxillary sinus but that was actually two large maxillary ostia with the absence of a left uncinate process. He was successfully treated with functional endoscopic sinus surgery.

Cervical thymic cysts are rare embryonic remnants that develop along the course of thymic migration in the neck. They usually occur during infancy and childhood, and they are extremely rare in adults. We report a case of cervical thymic cyst in a 53-year-old man. The patient presented with a small mass of the thyroid gland and a cystic mass at the left level II area of the neck. On histopathology, the thyroid mass was identified as a papillary carcinoma and the left-sided neck mass was diagnosed as a cervical thymic cyst lined with nonkeratinizing, flattened squamous epithelium. The cyst wall contained atrophic thymic tissue composed of lymphoid cells, epithelial cords, and Hassall corpuscles. Although it is rare, cervical thymic cyst should be considered in the differential diagnosis of a lateral cystic neck mass in an adult.

Ectopic eruption of a tooth is common in the dental arch, palate, and nose, but it is rare in the maxillary antrum. We present the case of a 35-year-old man with an ectopic canine and an associated dentigerous cyst in the maxillary sinus that masqueraded as an antrochoanal polyp.

Steatocystoma simplex of the infratemporal fossa: An uncommon location for a rare entity

January 1, 2011     Yekaterina A. Koshkareva, MD, Gregory S. Weinstein, MD, Michael Feldman, MD, and Gul Moonis, MD


Steatocystoma simplex is a rare entity characterized by the presence of a solitary cutaneous cyst derived from a sebaceous duct or gland. Multiple locations of this lesion have been reported previously. The purpose of this article is to report the unusual presentation of steatocystoma simplex as an infratemporal fossa mass. To the best of our knowledge, no case of steatocystoma simplex at this site has been previously reported. We also describe the radiologic and pathologic features of this entity, which might aid in diagnosis and management, and we discuss its etiology and treatment options.

Role of irrigation with hypertonic saline for a recurrent skull base hydatid cyst: Case report and review of the literature

August 31, 2010     Sadaf Zia, FCPS, Ather Enam, MD, Iftikhar Salahuddin, MD, and Aslam Khan, MD


Hydatid cyst is a parasitic disease caused by the tapeworm Echinococcus granulosus. This disease is a rare finding in the head and neck region, and its presentation varies according to the area involved. We report the case of a 25-year-old woman who presented with bilateral neck swelling, which was found on histopathologic examination to be caused by a hydatid cyst. The patient underwent surgical drainage of the cyst and a modified radical mastoidectomy, followed by a 3-month course of treatment with albendazole. However, she experienced a recurrence in the left neck region 1 year later. At that time, reexploration of the left mastoid cavity was performed, with debridement of diseased occipital bone and foramen magnum. Intraoperatively, we used a novel method of saline irrigation with 3% hypertonic saline, previously not tested on exposed nerves, in an attempt to prevent further recurrence. Four years after the second surgery, no disease recurrence was found, and no neurologic sequelae were noted. We conclude that hypertonic saline irrigation can be considered as an option for preventing recurrence in cases that are difficult to clear surgically, especially around cranial nerves, although more studies are needed to document the safety of this approach.

Cysts of the fossa of Rosenmüller: Report of two cases

July 31, 2010     Simon K.W. Lloyd, BSc(Hons), MPhil, FRCS(ORL-HNS), Riccardo A. Di Cuffa, DOHNS, MRCS, MRCGP, Felicity K. Seymour, MA, DOHNS, FRCS(ORL-HNS), Lloyd E. Savy, BSc(Hons), FRCR, and Henry R. Grant, FRCS


Cystic lesions of the nasopharynx are rare. Two cases of mucous retention cysts originating from the fossa of Rosenmüller are described, together with their characteristic radiologic appearance, which allows differentiation from other types of lesions in this region. The differential diagnosis and treatment options are discussed.

Adult nasal dermoid sinus cyst

July 31, 2010     Eugene A. Chu, MD and Lisa E. Ishii, MD


Midline congenital nasal lesions are rarely encountered in adults. We present the case of a 31-year-old man with a nasal dermoid sinus cyst who presented with a nasal dorsal abscess. We review the embryology of nasal dermoid sinus cysts, and we discuss their presentation, evaluation, and management in adults.

Ectopic thymic tissue presenting as a neck mass in children: A report of 3 cases

The presentation of ectopic cervical thymic tissue as an anterior neck mass is rare. We report 3 similar cases in 3 boys-2 who had a thymic cyst and 1 who had an ectopic cervical thymus. We discuss the radiographic presentation on ultrasound and magnetic resonance imaging in these cases. We also review the typical histologic picture; histology is the only way of diagnosing this condition.
