Thyroglossal Duct Cyst Carcinoma in a Young Female: Case Report and Review of Literature Thyroglossal duct remnants form during embryologic development and can develop into a thyroglossal duct cyst (TGDC). In rare cases, carcinoma is present within these cysts, most commonly papillary thyroid carcinoma. Diagnosis is difficult, but imaging and fine-needle aspiration (FNA) biopsies can help with the diagnosis. Given the rarity of TGDC carcinoma, treatment is not well agreed upon and can include the Sistrunk procedure, thyroidectomy, nodal dissection, and postoperative radioactive iodine treatment. Here, we describe the presentation, workup, and treatment of a 20-year-old female with papillary thyroid carcinoma present within both a thyroglossal duct cyst and the thyroid gland.

Adult-Type Rhabdomyoma of the Omohyoid Muscle Rhabdomyomas are benign tumors composed of mesenchymal tissue and having a histologic appearance similar to skeletal muscle. Extracardiac rhabdomyomas are rare, and the majority of the adult subtype occur in the head and neck (H&N) region. Diagnosis can be challenging due to fine-needle aspiration (FNA) and core needle biopsy being suspicious for sampling error from surrounding muscle or concerning for rhabdomyosarcoma. We present a case of a slowly enlarging left neck mass in the strap musculature of a 45-year-old Hispanic male. Multiple FNA and core biopsies failed to establish a diagnosis, and excisional biopsy was pursued revealing a hypertrophied left inferior belly of the omohyoid muscle. Histological analysis was diagnostic of an adult-type extracardiac rhabdomyoma, with complete surgical excision being the gold standard treatment for these tumors. The patient had an uneventful recovery. Skeletal muscle tumors of the H&N are uncommon, and benign extracardiac rhabdomyoma must be considered in the differential diagnosis to prevent unnecessarily aggressive intervention and appropriate patient counseling before and after surgery.

Chondro-Osseous Respiratory Epithelial Adenomatoid Hamartoma (COREAH): Case Report and Literature Review Chondro-osseous respiratory epithelial adenomatoid hamartoma (COREAH) is an extremely rare lesion of the nasal cavity with only 11 reported cases in the literature. COREAH is of interest as it may be easily mistaken for other diseases of the nasal cavity with higher morbidity, which require significantly different management strategies. We report, to the best of our knowledge, the oldest documented case of COREAH in the literature: an 83-year-old female who presented with headaches and was found to have a posterior nasal septal lesion. Uniquely, the patient had sequential scans performed 1 year apart demonstrating only minor interval growth. We describe our experience in managing a patient with COREAH and review the world literature, to better define aspects of the history, presentation, and investigations that may allow differentiation from more sinister disease.

A Case of Inverted Papilloma Originating from the Middle Ear and Review of the Literature Inverted papilloma (IP) with malignant transformation is rarely seen in the middle ear. Up to now, there have been 16 primary middle ear IPs reported in the English literature. Even though it is very rare in the middle ear, this pathology should be kept in mind for the differential diagnosis of middle ear masses. In this case, we report a 77-year-old female who had recurrent IP with malignant transformation and complication.

A Small Glomus Tympanicum Tumor Resected by Minimally Invasive Transcanal Endoscopic Approach We present a case of the transcanal endoscopic resection of a glomus tympanicum tumor. A 51-year-old woman presented with pulsatile tinnitus of the right ear persisting for 6 months. A reddish mass was observed through her tympanic membrane. A computed tomography scan revealed a small mass in the mesotympanum. She was diagnosed with a right-sided glomus tympanicum tumor. The glomus tympanicum tumor was classified as type 1 using the Glasscock–Jackson classification, class A using the Fisch classification, and class A1 using the modified Fisch and Mattox classification. The tumor was transcanally and completely resected by endoscopy without any complication. Before and after the surgery, pure-tone audiometry showed a normal hearing level. Preoperative right-sided pulsatile tinnitus resolved after the surgery. Transcanal endoscopic ear surgery is a favorable surgical method for small localized glomus tympanicum tumors.

Low-Grade Fibromyxoid Sarcoma of the Lateral Skull Base: Presentation of Two Cases Low-grade fibromyxoid sarcoma (LGFMS) is a rare slow-growing malignant tumour with a deceptively benign histologic appearance. Herein, we report two cases of LGFMS with variable clinical presentations. The first case was a 17-year-old female who referred to our department due to deaf ear on the right together with ipsilateral gag reflex impairment and globus sensation in the pharynx. The second case was a 35-year-old female with recurrent LGFMS, suffering from headaches, vertigo, and episodes of loss of consciousness. LGFMS of the temporal bone is a rare pathology, and to the best of our knowledge, no such cases have been reported before.

Cervical Subcutaneous Emphysema following Total Laryngectomy: An Unusual Complication of Nasogastric Intubation The nasogastric tube remains an important route of enteral feeding in the early postoperative period following total laryngectomy. Its insertion, however, is not without any risks of complications. In this article, we report an unusual case of inadvertent nasopharyngeal perforation secondary to intraoperative nasogastric tube insertion presenting as unilateral cervical subcutaneous emphysema in a patient who underwent total laryngectomy.

Floppy Closing Door Epiglottis Treated Successfully with an Mhealth Application Based on Myofunctional Therapy: A Case Report We introduce the first case reported to date of a floppy closing door epiglottis in an OSA (obstructive sleep apnea) patient treated successfully with an Mhealth smartphone application based on myofunctional therapy.

A Case of Focal Dermal Hypoplasia (Goltze Syndrome) Masquerading as Lingual Tonsillar Hypertrophy Focal dermal hypoplasia is a rare condition affecting organ systems of mesodermal origin. We present a rare case of this condition presenting with apparent palatine tonsillar regrowth and outline our management. Airway management should always be a consideration in this rare condition.
