We reported a unique case of posttraumatic giant infratentorial extradural intradiploic epidermoid cyst. A 54-year-old male, with a previous history of an open scalp injury and underlying linear skull fracture in the left occipital region in childhood, presented with a painful subcutaneous swelling, which had been developed gradually in the same region and moderate headache, nausea, vomiting and cerebellar ataxia. The duration of symptoms on admission was 3 months. Imaging studies revealed occipital bone destruction and giant extradural intradiploic lesion. The preoperative diagnosis was giant infratentorial extradural intradiploic epidermoid cyst. Surgery achieved total removal of the lesion, which was histologically confirmed and the postoperative course was uneventful. To our knowledge, this is the first case of giant infratentorial extradural intradiploic epidermoid cyst with a traumatic etiology described in the literature.

Treatments for alopecia areata include topical corticosteroid treatment, corticosteroid intralesional injection, systemic corticosteroid treatment, PUVA(psoralen-UVA) and topical immunotherapy. The therapeutic effects are variable. Alopecia totalis is hard to treat completely. Topical immunotherapy with dinitrochlorobenzene (DNCB), squaric acid dibutyl ester (SADBE) or diphenylcyclopropenone (diphencyprone, DPCP) represents the most accepted therapeutic modality for the treatment of extensive alopecia areata. We report two cases of alopecia totalis treated with DPCP. After DPCP treatment, total scalp hair was completely recovered.

We present an unusual case of peritoneal catheter migration following a ventriculoperitoneal shunt operation. A 7-month-old infant, who had suffered from intraventricular hemorrhage at birth, was shunted for progressive hydrocephalus. The peritoneal catheter, connected to an 'ultra small, low pressure valve system' (Strata$^{(R)}$; PS Medical,Gola, CA, USA) at the subgaleal space, was placed into the peritoneal cavity about 30 cm in length. The patient returned to our hospital due to scalp swelling 21 days after the surgery. Simple X-ray images revealed total upward migration and coiling of the peritoneal catheter around the valve. Possible mechanisms leading to proximal upward migration of a peritoneal catheter are discussed.

Alveolar soft part sarcoma (ASPS) with skull and brain metastases is extremely rare. A 53-year-old patient diagnosed as skull metastasis of ASPS visited our clinic complaining of an outgrowing scalp mass in spite of radiation therapy. Past medical history revealed that the patient had been diagnosed and treated for ASPS of the thigh 4 years ago. Magnetic resonance imaging revealed a hyperintense ovoid mass on the T2-weighted image, an isointense on the T1-weighted image, and a homogeneous enhanced mass with gadolinium. Another small-sized enhanced mass with mild peritumoral swelling was found at the deep white matter of the left frontal lobe. A gross total resection of the skull lesion with cranioplasty was performed for the surgical defect. A histologic examination of the specimens revealed metastatic ASPS involving the skull. Surgery with a total removal of the lesions may be effective for improving a patient's symptoms especially from neurological dysfunction.

목적: 이 연구의 목적은 두개골 랑게르한스 세포 조직구증의 특징적인 자기공명 영상소견을 기술하고 단순촬영과 컴퓨터 단층 촬영에서의 영상소견과 비교함에 있다. 대상 및 방법: 총 9명의 환자 중 10예의 병변을 대상으로 자기공명 영상을 분석하였다(연령범위: 5-42세, 평균 연령: 18세, 전예 여자). 9예에서 수술이나 미세 침 흡입 생검술에 의해서 병리학적으로 두개골의 랑게르한스 세포 조직구증이 증명되었다. 모든 환자는 자기공명영상을 시행하였고 이 중 7명 (8예) 에서 컴퓨터 단층 촬영과 단순 촬영을 시행하였다. 두 명의 숙련된 신경영상의학 의사가 영상에서 병변의 위치, 크기, 모양과 특징을 독립적으로 분석하고 병변의 범위와 주변 조직으로의 침범 여부를 비교하였다. 결과: 병변은 모든 두개골에 편향 없이 분포하였다. 자기공명 영상에서 종괴들은 조영증강되는 골 융해성 종괴(10/10)로 주로 판사이 공간에 위치하고(8/10) 두피(9/10)나 경질막(7/10)을 침범하였다. 경질막의 조영증강(7/10)과 비후(4/10)가 모든 병변에서 보였다. 골 융해성 종괴의 크기는 1.1 cm에서 6.8 cm의 범위였으며 모양은 원형(5/10)이거나 난원형(5/10)이었다. 컴퓨터 단층 촬영에서 병변은 판사이 공간의 골 융해성 종괴로(6/8) 두피의 침범(7/8)이 잘 보였다. 컴퓨터 단층촬영에서 골미란이나 골파괴가 자기공명영상보다 좀 더 분명하게 보였지만 연부종괴와 경질막의 조영증강 유무는 판단하기 어려웠다. 이와 대조적으로 단순촬영에서 모든 랑게르한스 세포 조직구증은 도려낸 병터 (punched out) 모양(4/8)이나 beveled-edge 모양(4/8)의 골융해성 종괴로 보였고 두피나 경질막으로의 침범은 판단 할 수 없었다. 결론: 두개골 랑게르한스 세포 조직구증의 특징적인 자기공명 영상소견은 판사이 공간에 위치한 골 융해성 종괴가 경질막과 두피를 침범하는 것으로, 자기공명영상이 단순촬영이나 컴퓨터 단층 촬영 보다 우월한 영상 기법이다.

This study was undertaken to investigate the effect of cingulate cortical ablation upon gastric ulceration, and the pathway through which cingulate cortex exerts the effect. 56 female rats were divided equally into cingulate (cingulate cortical ablation), cingulate-vagal (cingulate cortical ablation and vagotomy), normal control and vagal (vagotomy) groups. Cingulate cortex was ablated through a slit-shaped opening (1 mm in width, 13 mm in length) which was made symmetrically on both sides of, and parallel to, the sagittal suture by removing a bone flap from parietal and frontal bones on each side. Vagus nerves on both sides were transected around the distal end of the esophagus. In the normal control animals, surgical intervention ended with scalp incision. All rats were kept without restraint or food deprivation for 3 weeks after surgery. The stomach of each rat was inflated with 7 ml of physiological saline and then removed under deep anesthesia. The mucosal surface was examined under dissecting microscope for the location, shape and number of ulcers, and then enlarged photograph $(4{\times})$was taken. The incidence of ulcer in each group was counted and the number of ulceration as well as the total area of glandular mucosa were measured on the photograph. Results obtained were as follows: 1. The mean number of ulcer per stomach and the total area of ulcer exprssed as permillage of the total area of glandular mucosa were significantly higher in the cingulate group than the cingulate-vagal, the normal control and the vagal groups. There was no difference among the latter three groups. 2. The incidence of ulcer in the cingulate group was significantly higher than that in the .normal control group and was also higher, though not significantly, than those in the cingulate-vagal and the vagal groups. There was no difference among the normal control, the cingulate-vagal and the vagal groups. It is inferred from the above results that the cingulate cortex exerts an inhibitory influence upon gastric ulceration and that this influence is mediated by controlling the vagal activity.

Ewing's sarcoma is an uncommon malignant neoplasm of the long bone and it has a poor prognosis due to its early metastasis and aggressive local spread. It is mostly found before the age of 30 and it is rare in extraskeletal sites. Extraskeletal Ewing's sarcoma has been reported to occur in various sites including the larynx, scalp, nasal fossa, neck, chest wall, lung, pelvis, perineum, arm, finger, leg and toe, but it is extremely rare as a primary epidural tumor of the spine. We experienced a case of extraosseous epidural Ewing's sarcoma arising in the lumbar spinal canal at L3-L5 level in a 9-year-old boy. Following total laminectomy from L3 to L5 with a lumbar vertebrae and mass excision, he received chemotherapy with complete remission.

Objective : Postoperative subgaleal cerebrospinal fluid (CSF) collection is considered as one of the common minor surgical complication which can lead to prolonged hospitalization. We introduce "galeal tack-up suture" to prevent postoperative subgaleal CSF collection. Methods : Galeal tack-up suture consists of various surgical techniques which aim to fix galea to cranium in order to prevent CSF pooling in subgaleal space. A total of 87 patients who underwent craniotomy were divided into two groups while closing the wound : group A with galeal tack-up suture and group B with routine wound closure without galeal tack-up suture. The patients were observed for postoperative subgaleal CSF collection. Results : Among 87 cranitomy cases, galeal tack-up suture was performed in 32 cases and routine wound closure was done in 55 cases. Postoperative subgaleal CSF collection occurred in 13 cases (15%) in which 12 cases occurred in group B patients and 1 case occurred in group A patients (p=0.026). Conclusion : Galeal tack-up suture is an easy and effective technique in wound closure to prevent postoperative CSF collection.

Background Postoperative pain is one of the most common concerns of patients undergoing hair transplantation surgery. Because most patients are satisfied with the cosmetic improvement after transplantation, amelioration of postoperative pain would help to increase patient accessibility to hair restorative surgery and greatly impact patient satisfaction with the final cosmetic results. This study was performed to investigate postoperative pain after hair transplantation. Methods In total, 241 patients (202 who underwent follicular unit transplantation [FUT] and 39 who underwent follicular unit extraction [FUE]) were eligible for the study. Postoperative pain was evaluated on postoperative days 1, 2, 3, 4, 5, and 7 using the Wong-Baker Faces Pain Scale. The patients' medical records were retrospectively reviewed for information on the harvesting method, number of transplanted grafts, size of donor design, and laxity, elasticity, and glidability of the scalp in relation to postoperative pain. Results Postoperative pain after hair transplantation, assessed with the Wong-Baker Faces Pain Scale, seemed to provide very subjective results. None of the variables were correlated with postoperative pain in the FUT group. Such pain, however, tended to disappear by postoperative day 3. Patients in the FUE group experienced significantly less severe pain than those in the FUT group. Conclusions Postoperative pain was significantly less severe in patients whose donor hair was harvested by the FUE than FUT method. Postoperative pain had almost disappeared by postoperative day 3 in the FUT group, whereas only minimal pain was present even on postoperative day 1 in the FUE group.
