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.

A Case of Neurofibroma Presenting as a Nasolabial Mass

Neurofibroma is a benign neurogenic tumor thatmost often occurs in the head and neck region. However, a solitary neurofibroma on the nasolabial fold is extremely rare, with only a few reported cases reported in the English literature. A 45-year-old woman with a nasolabial mass visited our department, and we performed an excisional biopsy using asublabial approach. The histopathology of the mass revealed it to be neurofibroma. We report a unique case of neurofibromain thenasolabial region with an associated literature review. To the best of our knowledge, no such case has previouslybeen reported in Korea.

Primary Thyroid Lymphoma Associated with Dyspnea in an Old Age Patient: A Case Report / 대한갑상선학회지

Primary thyroid lymphoma is a rare tumor which patients usually present an enlarging neck mass, often causing local obstructive symptoms. Hypothyroidism is seen in 30-40% of the patients with primary thyroid lymphoma. We report a 77-year-old man with history of hypothyroidism, presenting enlarging anterior neck mass which pathologically confirmed as thyroid lymphoma with literature review.

Co-existence of Papillary Thyroid Cancer with Tuberculosis Involving the Thyroid and Ipsilateral Paratracheal Lymph Node: A Case Report / 대한갑상선학회지

There are relatively rare cases concerning about concurrent papillary thyroid cancer and thyroid tuberculosis with cervical tuberculous lymphadenitis in English literature so far. Cervical lymphadenitis (scrofula) is a common manifestation of extra-pulmonary invasion of the tuberculosis. A cervical tuberculous lymphadenitis could be confused with metastatic lymph node from the thyroid cancer. A 49-year-old woman with multiple right thyroid nodules of Bethesda category VI referred our department for surgery. We performed the right thyroid lobectomy with anterior compartment neck dissection. The histopathology revealed concurrent papillary thyroid carcinoma and thyroid tuberculosis with cervical tuberculous lymphadenitis. We report a unique case of concurrent papillary thyroid cancer and tuberculosis involving the thyroid gland and ipsilateral paratracheal lymph node with literature review. To our best knowledge, such case has not been reported earlier.

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.

Giant Multinodular Goiter, Mimicking a Direct Invasion from the Malignant Thyroid Neoplasm: A Case Report / 대한갑상선학회지

Multinodular goiter (MNG) is one of the benign thyroid neoplasm and nodular hyperplasia is the most common pathologic type. MNG could be misdiagnosed as a malignancy because of its characteristic, which is its growing tendency. A-70-year-old female was referred to our clinic from endocrinology, with the huge and recently rapid growing thyroid mass. We performed the neck sonography, its guided fine needle aspiration cytology (FNAC), neck CT and MRI. She was presumed as the malignant thyroid neoplasm except papillary carcinoma. The right completion thyroidectomy and anterior compartment neck dissection had been done and the nodular hyperplasia was diagnosed finally. We learned a valuable lesson from this case in the following. Even if the malignancy is strongly suggested in the radiology and clinically, more careful consideration in determining the surgical method and its extent is mandatory.
