One Case of a Primary Papillary Thyroid Carcinoma in the Intrathoracic Lymph Node / 대한이비인후과학회지

A primary papillary thyroid carcinoma in the intrathoracic lymph node is very rare. There are two potential explanations of the lesion. The first possibility of the lesion is metastatic disease from an occult primary thyroid papillary microcarcinoma. Other possibility is malignant transformation of the aberrant thyroid tissue within the intrathoracic lymph node, which is the favored etiology in this case. We experienced an extremely rare case of true intrathoracic thyroid cancer in a 78-year-old woman, presenting with an intrathoracic malignancy. We confirmed it as papillary thyroid cancer, but there were no primary sites of thyroid glands. So, we report this rare case of a primary papillary thyroid carcinoma in the intrathoracic lymph node.

A Case of Subcutaneous Cavernous Hemangioma Presenting as a Nasolabial Fold Mass / 대한이비인후과학회지

Hemangiomas are the most common vascular tumor of the head and neck region, but rarely involve the sinonasal cavity. The majority of these lesions present as a benign tumor of the skin and mucosa. Moreover, most nasal hemangiomas occur in the nasal septum or vestibule. The authors experienced a case of subcutaneous cavernous hemangioma that occurred from right nasolabial fold in a 40-year-old man, which was successfully treated by sublabial approach. We expected the tumor as a radicular or nasolabial cyst because of its location, clinical feature, and radiologic findings. However, the final pathologic diagnosis was cavernous hemangioma. We present the clinical characteristics, radiologic findings, and treatment of a subcutaneous hemangioma with a review of the literature.
