Abstract

Branchial cleft cysts are the most common lesions to arise laterally in the neck. Ectopic thyroid tissue within a branchial cleft cyst is rare, and a papillary carcinoma arising from this tissue is extremely rare. We present a case of a lateral neck cyst representing a primary papillary carcinoma that arose in ectopic thyroid tissue within a branchial cleft cyst in a 41-year-old woman. After the mass was surgically excised, thyroid ultrasonography, thyroid scintigraphy, and whole-body F18-fluorodeoxyglucose-positron emission tomography/computed tomography detected no abnormality. The negative findings notwithstanding, surgery on the thyroid gland was planned, but the patient refused it. Therefore, she was followed up with ultrasonography and scintigraphy for 5 years, during which time she exhibited no evidence of recurrence. Total thyroidectomy is still the primary option in such cases, but when it cannot be performed for any reason, vigilant follow-up is essential.

Abstract

Aneurysmal bone cyst is a benign and locally destructive bone lesion usually seen in the younger population. Its etiology is unknown. Its yearly incidence rate has been reported to be 0.14/100,000, comprising 1% of all bone tumors. It may develop primarily or arise from primary bone tumors. Hemorrhagic fluid content with a septated appearance is the characteristic feature of aneurysmal bone cyst. It is most commonly seen in the metaphysis of the long bones. In rare cases, the cyst is located in the skull. Primary treatment is surgical excision, and the recurrence rate after treatment is 10 to 30%. Based on a review of the current literature, there have been no previous reports of aneurysmal bone cyst located in the middle turbinate. We report a case of aneurysmal bone cyst with an atypical location and discuss the treatment of the patient with endoscopic surgery in light of relevant literature.

The retention cyst originates from the obstruction of a glandular structure and contains fluid, while the cholesteatoma contains keratinizing squamous epithelium.

Cervical thoracic duct cyst: Importance of preoperative suspicion for appropriate management of left-sided neck mass

Abstract

Cervical thoracic duct cysts occur infrequently but are an important consideration when evaluating cystic supraclavicular masses. Only 22 cases have been reported to date. We review the clinical presentation, evaluation, and treatment of 2 cases of large thoracic duct cysts treated with surgical resection. A high suspicion of thoracic duct cyst based on location, radiographic findings, and fine-needle aspiration results is sufficient evidence for recommendation of surgical excision. However, enlarged cysts, as noted in our cases, can obliterate or attenuate the thoracic duct, making it difficult to identify intraoperatively. A high suspicion of thoracic duct cyst is important for identifying and ligating the duct to prevent complications such as chyle leak or chylothorax.

Unusual presentation of Sjogren syndrome: Multiple parotid cysts

October 31, 2012     Ankur Gadodia, MD, DNB; Ashu Seith, MD; Raju Sharma, MD
article

Abstract

Sjögren syndrome is a chronic autoimmune exocrinopathy that destroys salivary and lacrimal gland tissue. We report an unusual case of this disease in a 40-year-old woman who presented with bilateral parotid cystic masses. As this case illustrates, Sjögren syndrome should be included in the differential diagnosis of bilateral cystic parotid lesions.

Hearing loss secondary to a nasopharyngeal retention cyst

article

Resection is generally not indicated for small, asymptomatic pharyngeal cysts. Symptomatic cysts, on the other hand, can be treated with aspiration or a complete transoral resection, particularly if the lesion is large.

Powered instrumentation is a good choice for the removal of maxillary sinus lesions. It is efficient and safe and preserves normal sinus mucosa.

Subglottic thyroglossal duct cyst: A rare intralaryngeal presentation

July 5, 2012     Regi Kurien, MS; Rajiv Michael, MS, DLO
article

Abstract

Thyroglossal duct cysts are common midline neck swellings that can present at any site along their migratory pathway. They are frequently situated just below the hyoid bone. Extension to the subglottic area is very rare; such an unusual presentation can complicate the diagnosis of a thyroglossal duct cyst. We report the case of a 30-year-old man who presented with a subglottic thyroglossal duct cyst and associated laryngeal symptoms. To the best of our knowledge, only 2 similar cases have been previously reported in the literature, both of which occurred in 2-year-old boys. We believe, therefore, that ours is the first reported case of a subglottic thyroglossal duct cyst in an adult. We discuss the clinical presentation, diagnosis, and treatment of our patient, and we summarize the literature on intralaryngeal thyroglossal duct cysts.

Fourth branchial cleft cyst with no identifiable tract: Case report and treatment approach

Abstract

We describe a rare case of a fourth branchial cleft cyst that had no identifiable tract. The patient was a 23-year-old man who presented with recurring neck abscesses. After six similar episodes, computed tomography finally demonstrated that the most recent abscess had extended into the thyroid gland, a finding that led to the correct diagnosis. Extensive surgical extirpation of the cyst with an adjacent neck dissection was performed, and the patient remained symptom-free at 25 months of follow-up. The occurrence of a fourth branchial cleft cyst with no clear tract presents a surgical dilemma, as complete dissection cannot be guaranteed. Consequently, such patients are predisposed to recurrence. We propose that definitive management of a fourth branchial cleft cyst with no identifiable tract focus on eliminating the likely embryologically based path of bacterial seeding. This includes a hemithyroidectomy in conjunction with a selective neck dissection to cover all areas where a fourth branchial tract may lie within the neck.

Aneurysmal bone cyst at the base of the skull

article

Abstract

Aneurysmal bone cysts have been described as pseudocysts in view of their lack of an epithelial lining. These cysts are uncommon, but when they do occur they typically involve the long bones of the extremities, the membranous bones of the thorax and pelvis, and the vertebrae. Skull involvement is uncommon. We present the case of a 14-year-old girl who presented with nasal obstruction and a swelling of the right cheek. Contrast-enhanced computed tomography detected a heterogeneous cystic mass involving the sphenoid and ethmoid bones. The mass was excised via a lateral rhinotomy approach, and it was identified as an aneurysmal bone cyst on histologic examination. The patient experienced a recurrence in the right sphenoid sinus within 3 months, and the lesion was removed via transnasal endoscopy.

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.
