Purpose: The epidermal cyst is a very common skin lesion which usually occurs in the hairy regions. They are generally small but rarely reach more than 5 cm in diameter. We present a patient with a giant epidermal cyst on buttock area. Methods: A 50-year-old man with a slowly enlarging, huge mass in his left buttock was examined. There was no history of trauma in this area. Physical examination revealed a soft, nontender, $15{\times}15cm$-sized mass in his left buttock. T1-weighted magnetic resonance images demonstrated a well-circumscribed, multilocular cystic lesion with homogeneous, slightly high signal intensity. On T2-weighted images the lesion had wide areas of high signal intensity. The mass was totally excised. Results: A histopathological finding revealed that the cystic wall was lined with whole layers of stratified squamous epithelium. Keratin layers from the surface of the epithelium were seen to be sloughing into the cystic lumen. Multinucleted giant cells were found outside the cystic wall. Conclusion: Herein we report a rare case of giant epidermal cyst occurring on the buttock.

Cystic lesion of the jaw are frequently encountered clinically. Although they rarely lead to development of tumors, they can result in resorption of the jaw bone or asymmetry of the face may occur. The purpose of this study is to find the clinical and histopathological pattern of cysts and to help better understanding for the diagnosis and treatment of jaw cysts. The hospital chart, out-patient chart, panorama X-ray, histopathological report and operation report of 246 patients were reviewed who had been diagnosed as cyst. Sex distribution, age distribution, classification, anatomic distribution, clinical sign & symptoms, treatment, post-operation complications, recurrence rate were studied. Then significant difference between the diameter of cyst with bone graft and none-bone graft was calculated with SAS program. The results were as follows. 1. Among the total patient of 246 cases, male were 163 case(67.0%), and female were 83 case(37.0%), male predominated by the ratio of 1.98. 2. By age group, the 20's accounted for the largest proportion of the cases(27.2%) and the 30' accounted for the 2nd largest proportion of the case(19.5%). 3. Radicular cyst and dentigerous cyst were most common cysts, irrespective of 166 case(67.5%) and 62 case(25.2%). 4. Clinical sign & symptoms were swelling(167case), pain(85case), pus discharge(53case), teeth discoloration(28case), indicating that most complaints were related to inflammation and facial asymmetry. 4.9% of the total cases were discovered accidentally. 5. The primary site of cysts were maxillary anterior area(43.9%), the others were, in descending order, mandibular posterior area(25.6%), maxillary posterior area(14.6%). 6. Enucleation with endodontic treatment was a main treatment method(133 case, 54.1%) and 38 cases(15.4%) were enucleation with extraction, and 37 cases(15.0%) were only enucleation, and 21 cases(8.5%) were enucleation with bone graft. 7. The average diameter of cysts with bone graft was significally greater than with non-bone graft(p<0.05). 8. Post-operation complications occurred in 10 case(4.1%), all of this were due to secondary infection.

흑산도 근해의 가두리 양식장에서 아가미에 백색 결절을 주 증상으로 하는 조피볼락이 발견 되었다. 간과 신장에서는 병원균의 검출과 병리 조직학적인 변화가 전혀 발견되지 않았다. 아가미의 경우, epitheliocystis, Microcotyle sebastes 및 아가미 새변의 연골내에 미동정 생물(unknown aetiology)의 cyst가 확인되었다. Epitheliocystis의 cyst크기는 약 44.1-68.9 $\mu{m}$이었고 주로 새변의 끝과 중간부위에 기생하고 있었다. 그러나 새변내의 cyst형성에도 불구하고 숙주의 반응은 미약했다. M. sebastes는 2차새변에 고착기를 이용하여 달라붙어있었으며, 이로 인하여 상피세포의 증생이 발생하였다. 미동정 생물체의 경우, cyst는 호산성의 물질로 충만되어 있었고 cyst전체가 연골에 의해 싸여 있는 형태를 보였다. 하지만 이러한 cyst의 형성에도 불구하고 새변의 크기가 증대된 것 이외에는 별다른 병리학적인 증상은 보이지 않았다. 이들 기생충들의 의한 숙주세포의 조직반응은 미약하여 폐사는 유발되지 않았지만, 호흡과 삼투압 조절에는 장애가 있을 것으로 추정된다.

The objective of this study is to investigate the changes in concentrations of leptin and insulin in serum of Korean cattle (Hanwoo) with reproductive disorders and to examine the relationship among leptin, insulin, and body condition score (BCS). The concentration of leptin in serum of pregnant Hanwoo showed insignificant difference from that in serum of Hanwoo with reproductive disorder, such as repeat breeding, follicular cyst, corpus luteum cyst, ovarian atrophy, and feeble estrus (p>0.05). However, the concentrations of leptin and insulin in serum were changed with different BCS value. In emaciated Hanwoo (BCS $2.0\sim2.9$), they were significantly decreased compared to BCS $3.0\sim3.4$ (p<0.05). The leptin showed different genotypes with different BCS value. In BCS $2.0\sim2.9$, C/T genotype was expressed (83.3%) more than C/C (16.7%) or T/T (0%) genotype, whereas C/C genotype was expressed (62.5%) more than C/T (25.0%) or T/T (12.5%) genotype in BCS $3.5\sim4.0$. The insulin concentration in follicular fluid obtained from ovary with follicular cyst which has follicles having diameter of $25\sim40 mm$ was significantly higher (p<0.05) than those in normal follicle fluid which has follicles having diameter of $3\sim10 mm$. These results showed that concentration of leptin and insulin in serum were related to BCS value and follicular size and suggest that the changes in concentration of leptin and/or insulin in serum could be a potent biomarker for diagnosis of bovine reproductive disorder.

A 25-year-old Uzbek male presented with right upper abdominal pain for 20 days. On radiologic studies, a huge cystic mass was noticed in the right liver which was suspected as parasitic. The patient received right hepatic segmentectomy (segment 7), and the surgically resected mass was confirmed as cystic echinococcosis (CE), measuring 10.5 cm in its diameter. The inner surface of the cyst was bile-stained. The patient was discharged on the 8th hospital day, and was rechecked 6 months after the surgical intervention without any evidence of recurrence. The present report describes findings of an imported case of CE which represented ultrasound images of the 'ball of wool'.

Ultrasonographic diagnosis of genital disease and early pregnancy diagnosis was performed in Korean native cattle. The size of ovarian follicle in preovulation, luteal stage and follicular cyst was 18.9, 9.2 and 27.6 mm, respectively, and the thickness of follicular wall was 2.3, 1.8 and 2.8 mm, respectively. The size of corpus luteums in formation stage, activity stage, regression stage, cystic corpora lutea and luteal cyst was 6.2, 11.3, 8.6, 26.7 and 25.9 mm, respectively. The thickness of luteal wall in cystic corpora lutea and luteal cyst was 8.4 and 4.9 mm, respectively. The size of embryo or fetus on day 25, 27, 30, 35, 40, 45 and 50 was 0.8, 0.9, 1.3, 1.5, 2.2, 2.8 and 3.8 cm, respectively. The size of amniotic vesicle on day 25, 27 and 30 was 1.2, 2.1 and 3,0 cm, respectively. The diameter of pregnant uterus on day 25 and 27 was 7.0 and 7.8 cm, respectively. It was concluded that the ultrasonographci values determined in this study can be used as references for the treatment of genital disease and early pregnancy diagnosis in Korean native cattle.

The pulmonary sequestration is an uncommon congenital anomaly characterized by the presence of a part of lung tissue which is supplied by an aberrant artery from the aorta or its branch and usually has no communication with the normal bronchial tree. It was first presented by Hubber in 1777 and presented in details by Pryce in 1946. We present a case of extralobar pulmonary sequestration experienced recently with a case of intralobar type experienced in 1962. The patient was 11 year old male with the complaint of chronic productive cough. Serial chest films showed a large cyst with or without the air-fluid level on the posterobasal segment area of the left lower lobe. Bronchography showed no definite communication between the cyst and bronchial tree. On operation, the cystic lesion was supplied by an aberrant artery from the descending thoracic aorta 5 cm above the aortic hiatus and was sited at the posterobasal segment area of the left lower lobe. We performed the sequestrectomy and the sequestration was surrounded by its own pleura, 6.8x3.9x3.2 cm in size, contained the pale brown mucoid secretion in a large cyst and showed the primitive alveolar structure of the wall. The aberrant artery was 1 -5 cm long, 0.3 mm in internal diameter and arterio-sclerotic. We also compared 6 cases of collection, 5 intralobar and 1 extralobar type, presented in Korea.

A 51-year-old male who is right-handed visited the outpatient for right fingers-drop. The patient's fingers, including thumb, were not extended on metacarpophalangeal joint. The active motion of the right wrist was available. The electromyography and nerve conduction velocity study were consistent with the posterior interosseous neuropathy. Further evaluation was done with the magnetic resonance imaging for finding the space-occupying lesion or any possible soft tissue lesion around the radial nerve pathway. On magnetic resonance imaging, the ganglion cyst, which was about 1.8 cm in diameter, was observed on the proximal part of the superficial layer of the supinator muscle (Arcade of Frohse). The surgical excision was done on the base of ganglion cyst at the base of stalk of cyst which looked to be connected with proximal radioulnar joint capsule. The palsy had completely resolved when the patient was observed on the outpatient department a month after the operation.

To improve the cosmetic results of removing epidermal cysts, minimally invasive methods have been proposed. We proposed a new minimally invasive method that completely removes a cyst through a small hole made by a $CO_2$ laser. Twenty-five patients with epidermal cysts, which were 0.5 to 1.5 cm in diameter, non-inflamed, and freely movable, were treated. All of the patients were satisfied with the cosmetic results. This method is simple and results in minimal scarring and low recurrence rates without complications.
