ABSTRACT
The hyalinizing trabecular adenoma (HTA) of the thyroid gland is a rare benign tumor, which is characterized by a trabecular growth pattern with hyaline stroma. This tumor is occasionally misdiagnosed as papillary carcinoma and medullary carcinoma. Distinguishing pathologic findings and immunochemical studies are needed to make a definite diagnosis. Recently, we experienced a case of HTA of the thyroid gland. A 54-year-old woman presented with both thyroid nodules (mainly the left thyroid). Fine needle aspiration cytology showed atypical follicular cells. We performed left hemithyroidectomy and finally diagnosed the specimen as HTA. We present this rare case with a brief review of the disease entity.

Ocular symptoms related to orbital fracture occur immediately after the fracture in most cases. However, authors experienced a delayed onset diplopia occurred 16 months after orbital floor fracture. A 19-year-old man, who had right orbital floor fracture 16 months ago, presented with diplopia of upward gaze. At the time of the fracture, no surgery was performed because the fracture was minimal and there were no particular symptoms. Physical examinations revealed a minor ocular motility restriction of upward gaze, but orbital floor showed no definite interval change on computed tomography. Severe adhesion between the orbital fat tissue and orbital floor was noted intraoperatively and the adhesion was dissected. After the operation, the patient showed remarkable improvement in diplopia and restriction of the ocular motility.

Traumatic optic neuropathy is a complication resulting from facial trauma, with an incidence of 2% to 5%. The most widely accepted treatments include observation, high dose steroid, surgical decompression and combination therapy of steroid and surgical treatment. However, there has been no established mode of treatment and there are still debates about what the best treatment should be for the patients with optic canal fracture. We experienced two cases of traumatic optic neuropathies due to intracanalicular fracture of the optic canal after trauma. Surgical decompression was performed using an endoscope int-ranasally one day after injury as required for minimal invasive surgery. We report the results and progression of these two cases.
