ABSTRACT
Amyloidosis is defined as a deposit of amyloid substance. While it rarely occurs in the head and neck region, it is most commonly found in the larynx. Laryngeal amyloidosis can occur in the false vocal cord, ventricle, and glottis etc. The typical feature of laryngeal amyloidosis is a round yellowish submucosal mass. A 72-year-old male presented with voice change that began a couple of years ago. The rigid laryngoscopy showed a whitish patch in the medial and superior surfaces of the left true vocal fold. He was pathologically diagnosed with amyloidosis by laryngeal microsurgery. With a relevant review of literature, we report this case as it demonstrates rare, atypical features of laryngeal amyloidosis.
ABSTRACT
Mantle cell lymphoma (MCL) is a rare subtype of B-cell neoplasm and it accounts for about 3~6% of all non-Hodgkin's lymphomas. It occurs mainly in middle-aged or elderly man, involving the extra-nodal sites such as gastrointestinal tract, bone marrow and Waldeyer’s ring. The incidence of the MCL in salivary gland is about 3%. The blastoid MCL is a rare variant and it has a very aggressive clinical course. It is extremely rare to be arising from the parotid gland. To our knowledge, similar case has not been reported in domestic literature, one case has been described in English literature. We experienced a rare and unique disease entity and report it with brief literature review.

ABSTRACT
Herniation of the temporomandibular joint (TMJ) into the external auditory canal is rare as TMJ and external auditory canal are separated by an anterior bony wall of external auditory canal. The bony defect of the anterior external auditory canal can be caused by trauma, otologic procedure, neoplasm, inflammation and a rare congenital bony defect. Conservative treatment is available if the severity of the symptom is mild or asymptomatic. However, surgical procedure is considered if the patient experiences severe distress. There have been no reported cases of surgical-related complications and recurrence during postoperative follow-up period. Herein we report the very first case of foreign body prolapse involving herniation from TMJ extending into the external auditory canal.
ABSTRACT
Parathyroid carcinoma accounts for about 0.5%-5% of all parathyroid neoplasms. Very rarely, but if the intrathyroidal parathyroid gland is present, the carcinoma can arise in that developmental anomaly. It is very difficult to distinguish a thyroid nodule from an intrathyroidal parathyroid neoplasm with preoperative radiologic and cytologic evaluations. A 59-year-old male was initially evaluated as presenting a follicular thyroid neoplasm accompanied by hyperparathyroidism. He received hemi-thyroidectomy with central neck dissection and subtotal parathyroidectomy. The final pathology evaluation revealed intrathyroidal parathyroid carcinoma and hyperplasia of contralateral parathyroid glands. We report this very rare and unique clinical situation with a literature review.
ABSTRACT
The tracheostomy directs external air into the airway tract. This process causes mucosal dryness, irritation and inflammation in the tracheo-bronchial tree. In order to prevent such problems, several methods are applied; ointment application, humidification and careful suction etc. The heat-moisture exchanger (HME) is commercially sold device that assists heating and humidification of the inhaled air. The authors experienced successful treatment outcome of intractable tracheitis caused by repetitive and vigorous intra-tracheal suction by applying HME in a total laryngectomized patient. We report an interesting and didactic case with a brief literature review.
