The term "pineal anlage tumor" has been recently proposed and few cases have been reported. We report the first Korean case of pineal anlage tumor in a 6-year-old girl who complained of headache and vomiting for 2 months. Brain MRI revealed a well defined, lobulated, calcifying mass in the pineal region. Tumor was totally removed. Pathological examination revealed a primitive pineal parenchymal tumor with melanotic epithelial component that was similar to histologic findings of melanotic neuroectodermal tumor of infancy, so-called retinal anlage tumor and of the developing pineal gland. The tumor was composed mostly of small, undifferentiated cells, Flexner-Wintersteiner rosettes, and ganglionic differentiation. The tumor also contained the cartilage and skeletal muscle cells.

PURPOSE: LASIK, one of the currently popular ophthalmic procedures, can sometimes result in dry eye symptoms. In the patient who had underwent LASIK operation, the periorbital surgery may be more likely to lead to such a complication as dry eye symptom. We would like to report a case of corneal abrasion occurred after transconjunctival blepharoplasty in post-LASIK state and suggest the method about preventing the complication. METHODS: A 30-year-old female patient underwent transconjunctival blepharoplasty and microfat graft into the face. She had history of LASIK operation 2 years ago. Corneal protector was applied to both eye during transconjunctival operation. After the surgery, she complained of visual blurring at left side. Ophthalmic examination revealed corneal abrasion of left eye. RESULTS: Cornea protecting lens was applied to left eye for 2 weeks. Steroid and antibiotic eye drops were applied for relieving the symptoms and the prevention from progressing of complication. After 1 week, visual power and acuity was recovered to preoperative state. No other specific complications happened. CONCLUSION: Post-LASIK patient may have possibility of decreased corneal sensation and tear production. Preoperative ophthalmic examination is recommended for the prevention of complication. When corneal protector is applied, we suggest Optagel(R) as a useful lubricant.

Mutation in the p53 suppressor gene is the most common genetic alteration found in human cancers including primary brain tumors. Ki-67 labeling index(LI) is known to be a marker of proliferating activity. The purpose of this study was to verify whether an immunohistochemical expression of p53 antibody and Ki-67 LI could be related to different clinicopathologic parameters including histologic grade, size, invasiveness and recurrence of the brain tumors. Materials were based on the 147 surgically resected brain tumors during the last two years. Of the 147 brain tumors, there were 35 astrocytic tumors, 35 meningiomas, 10 oligodendrogliomas, 7 craniopharyngiomas, 5 dysembryoplastic neuroepithelial tumors, 4 medulloblastomas, 5 ependymomas, 23 pituitary adenomas, 9 schwannomas, and 14 other brain tumors. The p53 expression and Ki-67 LI were higher in malignant brain tumors including astrocytic tumors, medulloblastoma, PNET and gliosarcoma. The p53 positivity was correlated with histologic grades and tumor recurrence. The brain tumors with a high Ki-67 LI(>6%) also showed a close relationship to a higher histologic grading, radiological invasiveness and recurrence. There was no evident correlation with the age and tumor size with p53 expression and Ki-67 LI. These results suggest that p53 overexpression and high proliferation potential of the tumor cells are associated with the higher histologic grade and aggressive clinical course in the central nervous system tumors.

PURPOSE: Microfat graft is a common procedure for correcting tear trough deformity and dark circle. Because the tissue in this area is very thin, the grafted fat, sometimes, induces palpable lumps and uneven skin contour. When it happens, the surgical removal of the grafted fat is often needed. The authors made attempt of transconjunctival approach for removal, and this made infraorbital fat repositioning possible at the same time. METHODS: 15 female patients with history of microfat graft on lower eyelid, got operation for the grafted fat removal with transconjunctival approach from April of 2009 to July of 2010. The dissection was performed in accordance with infraorbital fat repositioning surgery. Through the transconjunctival incision, knotted fat on orbital septum and orbicularis oculi muscle was removed without damage on skin. After grafted fat removal, subperiosteal space was made 1~2mm below the inferior orbital rim by elevating periosteum. With preserving orbital septum, infraorbital fat was repositioned and anchored to subperiosteal space. Finally, transconjunctival incision was closed with absorbable suture material. RESULTS: 14 patients in the study showed satisfactory results. The problems like uneven skin contour and knotted fat mass, were all solved. In only one patient, incomplete correction was observed, as bulging on her right lower eyelid still remained. One patient complained of transient numbness on lower eyelid, but there was no specific complication other than this. CONCLUSION: The authors attempted the method of transconjunctival approach to remove former grafted fat in lower eyelid and reposition infraorbital fat simultaneously. Since the study brought great results, the method would be helpful to patients and surgeons.

Infraorbital dark circles refer to the darkness of lower eyelids and can be a significant cosmetic problem for the people of any age and sex. Although the general concern for dark circles is increasing, little has been published about the treatment of dark circles in the scientific literature. Dark circles are not a single disease but combination of causative symptoms. We classified patients to five groups according to patients' symptoms; bulging of infraorbital fat(Ia), sunken lower eyelids(Ib), depression or groove on midface(Ic), thin translucent skin(IIa), and excessive pigmentation(IIb). We reviewed medical records and photographs of patients retrospectively. The classification of patients and the treatment of the groups were evaluated. Problems of shape, especially bulging of infraorbital fat was the main cause of dark circles in most patients(65.2%). The treatment of each group included transconjunctival fat reposition or removal(Ia), single fat cell graft(Ib,IIa), microfat graft(Ic), and various dermatologic therapies(IIb). We obtained better results when we did combination of the treatments according to symptomatic groups.

Transconjunctival lower blepharoplasty has gained interest because of less-invasiveness and fast recovery. This is a study about operative skill, strength, and weakness of transconjunctival lower blepharoplasty and a trial for suggesting the guidelines for patient selection. The authors reviewed the medical records and photographs of 530 patients(M:F=470:60) who underwent transconjunctival lower blepharoplasty with orbital fat reposition and subperiosteal septal reset, retrospectively. Most of the patients were satisfied with results for correction of orbital fat bulging and tear trough deformity. Eighteen patients(3.4%) developed relapse of fat bulging requiring revision with subsequent fat removal(seventeen patients) or fat reposition(one patient). Two patient(0.4%) developed entropion. One case was corrected with revisional surgery and the other case was recovered after an injection of triamcinolone. Delayed hematoma was developed in five patients. Surgical evacuation was required in 3 cases. Minor problems included postoperative swelling, bruise, and transient paresthesia that resolved spontaneously. Transconjunctival lower blepharoplasty is an excellent surgical choice for correction of orbital fat bulging and tear trough in the patients who have proper tension of soft tissue. Invisible scar, fast recovery, and low complication rate are merits of this method.
