A Case of Co-Existence Squamous Cell Carcinoma with Granuloma in Posterior Glottis / 대한이비인후과학회지

The laryngeal granuloma (LG) is non-neoplastic lesion that mainly develops in the posterior vocal folds. It is welknown that mis- or overuse of voice, habitual coughing, and endotracheal intubation can become the cause of LG. The laryngopharyngeal reflux also comes into the spotlight as an etiologic factor. Although LG has a tendency to recur easily, it is not a premalignant lesion. The co-existence with granuloma and laryngeal cancer has not been reported earlier. Recently, we encountered a 72-year-old man with a posterior glottic mass, which was diagnosed as squamous cell carcinoma coexisting with granuloma. To our knowledge, this is a first report on two coexisting carcinomas in the glottis.

A Case of Recurrent and Multiple Schwannomas in the Caudal Septum

Schwannomas are benign neoplasms arising from the sheath of myelinated nerve fibers and may occur in any part of the body. They mostly occur in the head and neck region, accounting for about 25% to 45% of all cases. The eighth cranial nerve is the most common site of origin. About 4% of all head and neck schwannomas originate in the nasal cavity and paranasal sinuses. The best treatment of schwannomas is surgical excision. Since it is an encapsulated tumor, difficultly is rarely encountered in its complete removal, and recurrence is unlikely. We present a unique and rare case of a 71-year-old man with a recurrent septal mass, finally diagnosed as a schwannoma, with a review of the literature.

A Case of MALT Lymphoma of Buccal Area / 대한이비인후과학회지

Mucosa-associated lymphoid tissue (MALT) lymphoma, known as a distinctive type of non-Hodgkin's lymphoma, is an extranodal marginal zone B-cell lymphoma. It most frequently occurs in the stomach but has also been described in various non-gastrointestinal lesions, such as the salivary glands, conjunctiva, thyroid, orbit, lung, breast, kidney, liver, and prostate etc. It occurs very rarely in buccal mucosa. The MALT lymphoma tends to remain localized for long periods and respond to locally direct therapy. We recently encountered an 80-year-old male presenting with a foreign body sensation in the oral cavity; he was finally diagnosed as MALT lymphoma. We report this rare and unique case with a review of literature.

A Case of Metastatic Renal Cell Carcinoma of Parotid Gland / 대한이비인후과학회지

Renal cell carcinoma (RCC) is known for its high propensity for early metastasis and one third of patients diagnosed with RCC present with metastatic disease at the time of diagnosis. RCC commonly metastasizes to the lung, bone, liver, brain, and skin by hematogenous spread, whereas metastasis to the head and neck region is rarer. In cases of head and neck metastasis, the thyroid accounts for a large percent. Parotid metastasis from renal cell carcinoma is an extremely rare finding. We recently encountered a 67-year-old man with left parotid mass and finally diagnosed as metastatic renal cell carcinoma. We report the rare case with a review of literature.

A Case of Central Skull Base Osteomyelitis Concurrent with Multiple Lower Cranial Nerve Palsies / 대한이비인후과학회지

In most cases, skull base osteomyelitis arises from infections of external auditory canal, middle ear or paranasal sinuses. On the other hand, atypical or central skull base osteomyelitis has no evidence of external otitis or other infection sources. It is often found located on clivus and involves lower cranial nerves and brainstem through the foramina of skull base. The overall rate of mortality reaches 10% and long-term neurologic sequelae are seen in additional 31% of cases regardless of aggressive treatment. We recently encountered a 68-year-old man with right facial pain and generalized headache, and we achieved good outcome with the recovery of vocal cord palsy and disappearance of headache by surgical debridement and long-term antibiotics. We report it with a review of literature.

Giant Ancient Schwannoma of the Lateral Neck Presenting with Preoperative Horner's Syndrome / 대한이비인후과학회지

While ancient schwannoma (AS) from the cervical sympathetic chain is very rare. Preoperative Horner's syndrome resulting from cervical sympathetic chain schwannoma (CSCS) is extremely rare. A 58-year-old woman visited our clinic with a huge lateral neck mass that had been present for thirteen years. Ptosis and enophthalmos were observed on the left eye. After radiologic evaluation, we assessed the CSCS by performing surgical excision. Finally, pathologic examination revealed it to be AS. There has been no recurrence for 15 months after discharge, however Horner's syndrome has become more prominent. We report this unique case of ancient schwannoma with literature review.
