기관지기원낭종은 primitive foregut의 발생학적 이상에 의해 형성되는 드문 질환이며, 주로 폐실질과 종격동에 발생한다. 피부나 피하조직에서 발생한 기관지기원낭종은 흔하지 않으며, 이 중 견갑부에 발생한 것은 매우 드문 것으로 알려져 있다. 저자들은 20개월 된 남아의 좌측 견갑부에 발생한 기관지지원 낭종 1예를 보고하고자 한다. 환아는 피부과에서 절개 생검 및 소파술을 시행 받았고, 표피 낭종으로 진단되었다. 하지만 상흔 치유 도중 추가적인 낭성 종괴가 촉진되었다. MRI상 피하조직에 경계가 분명한 낭성 종괴가 관찰되었다. 절제된 낭종은 점액세포를 동반하는 pseudostratified ciliated columnar epithelium로 피복되어 있었으며, 기관지기원낭종으로 진단되었다.

Plantar corn is a circumscribed and sharply demarcated hard mass of traumatic hyperkeratosis, which has a central core impacting the dermis deeply and causes pain while walking. The cause of the corn is the mechanical stress to the skin induced by several causative factors; extrinsic(tight shoes) or intrinsic(bony prominence), or combined(the claw toe). We found 7 cases of patients with a painful recurrent plantar corn which had an epidermal cyst under its lesion. These corns and cysts were excised totally and there was no recurrence in all cases during two to four months follow-up period. We think that an epidermal cyst may be another intrinsic factor for the development of a plantar corn. So, an epidermal cyst should be considered once in a recurrent plantar corn to be recalcitrant against popular treatments.

유피낭종(dermoid cyst)은 표피형태의 상피세포로 이루어진 낭종의 벽에 피부부속조직을 포함하는 발생학적 낭종이다. 눈썹 부근이나 구강저의 중심선에 호발하지만 혀, 입술, 협점막의 병소도 보고된 바 있다. 이 병소는 천천히 커지고 무통성이며 임파선비대는 동반하지 않는다. 내용물은 피지성, 화농성등이며 크기는 수 mm에서 12cm까지 다양하다. 조직학적 특징은 상피세포 이장과 낭종벽내의 땀샘, 피지샘, 모낭동의 피부부속조직의 존재이다. 유피낭종의 치료는 완전절제이다 완전한 절제시 재발의 가능성은 거의 없다. 본 증례의 2세 여자환아는 1년 전에 넘어진 이후 상순에 딱딱한 것이 생겼다는 것을 주소로 연세대학교 치과대학병윈 소아치과에 내원하였다. 임상 구강검사 결과 둥근 고무질감의 종괴가 상순에서 관찰되었다. 조직학적 검사를 위해 조직생검을 시행하였으며, 낭종의 벽에서 피지샘이 관찰되었다. 이에 상순에서는 드물게 발생하는 유피낭종으로 진단되어 보고하는 바이다.

Epidermoid cysts located in floor of mouth can be easily removed intraorally. The cysts inferior to mylohyoid muscle have been excised transcervically. However, an intraoral removal of a cyst extended inferior to mylohyoid muscle has not been reported yet. A 20-year-old female visited to the hospital with a cystic mass in submental region. Neck computed tomography revealed a 6.0${\times}$4.3cm sized circumscribed cystic mass in midline of submental area. The cyst lied external to the genioglossal and geniohyoid muscle, extending inferior to mylohyoid muscle. The mass was removed successfully by intraoral approach. It was performed under the exposure by the division of genioglossal and geniohyoid muscle, traction of the cystic wall after aspiration of the cyst, and digital compression externally.

Background and Objectives : Microsurgical resection of intracordal cysts is technically difficult and challenging because the wall of cysts may be tightly attached to underlying vocal ligament and/or overlying epithelium, and therefore their thin wall will easily rupture during surgical dissection. We aimed to evaluate the voice outcomes of standard microflap subepithelial resection and the recurrence rate depending on the intraoperative rupturing of the cyst. Materials and Methods : Medical records of Samsung Medical Center, Seoul, Korea, were reviewed for sixty-four consecutive patients who received surgical resection of vocal cyst using microflap subepithelial dissection technique between the year 2004 and 2013. Meticulous dissection was performed to completely remove the cyst wall while preserving the mucosa and the lamina propria as much as possible. Voice outcomes and recurrence rates were compared according to the type, size and the intraoperative rupture of cyst. Results : Presence or absence of cyst rupture was clearly described in the operation records of 41 patients. Intraoperative rupture of the cyst occurred in 32 of 41 (78%) patients. The recurrence was detected in 5 of 64 (7.8%) total cases and 4 of 32 (12.5%) cases of ruptured cyst, but not in 9 cases of intact extirpation. Rupture was more common in case of mucous retention cyst compared with epidermoid cyst (p=0.036). Subjective and objective voice parameters were measured at before and 3 months after surgery, which improved regardless of the cyst rupture. Conclusion : Although complete microsurgical extirpation of intracordal cyst while keeping the cyst wall intact is technically difficult, meticulous dissection with maximal preservation of surrounding tissue may warrant the improvement of voice outcomes.

Objectives : The aim of this study is to report the effect of surgical method after Bufonis Venenum Pharmacopuncture Anesthesia on epidermal cyst. Methods : A 49-year-old male was presented with a $1.5{\times}1.5(cm)$ sized epidermal cyst on the upper back. Local anesthesia was achieved with Bufonis Venenum pharmacopuncture. After 5 minutes, 2.5cm incision was made using 11th blade. To minimize bleeding, the laser($CO_2$ Hani-maehwa laser-surgical mode) was excised to the cyst wall. After incision, cyst were separated and removed using adson forceps and iris scissors. Then buried intradermal suture and simple interrupted suture were performed. Yeonkyopaedok-san was administered for 5 days for anti-inflammatory effects. After 10 days, the suture was removed after confirmation of skin adhesion. Results : Cyst size measured $1.0{\times}1.0{\times}1.0(cm)$. Until the suture is removed, Adverse effects were not reported. Conclusions : Bufonis Venenum pharmacopuncture applies to local anesthesia. Korean medicine cautery method applies to laser($CO_2$ Hani-maehwa laser). It can be considered that To expand the application of surgical treatment in korean medicine.

Objectives : The study is to report cases of open/closed types of epidermal cyst removed by surgical method with Bufonis Venenum pharmacopuncture. Methods : 2 patients were diagnosed each open/closed epidermal cyst. Local anesthesia was achieved with Bufonis Venenum pharmacopuncture. Incision was made using 15^th blade and the CO₂ Hani-maehwa laser. After cyst was removed, simple interrupted suture was performed. Eunkyo-san and Yeonkyopaedok-san were administered respectively for 7 days for anti-inflammatory effects. Results : Local anesthesia was maintained until epidermal cysts were clearly removed. The suture was removed after confirmation of skin adhesion. Adverse reactions were not reported. Conclusions : Epidermal cysts were removed surgically after Bufonis Venenum pharmacopuncture anesthesia and the risk of infection can be prevented by administering herbal medicines that have anti-inflammatory properties. It is difficult to visually diagnose closed type of epidermal cyst and then suggests that imaging equipment such as ultrasound is required.

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.

Epidermal cysts are generally benign tumors that usually originate from the skin caused by inflammation of hair cortex and proliferation of epidermal cells within the dermis; however, for these cysts to occur in the bony external auditory canal (EAC) is rare. They are often present as a solitary, painless lesion and usually asymptomatic and the diagnosis depends on the results of the histological examination. In treatment, the cyst wall must be completely removed surgically. We recently encountered a 82-year-old male with a mass in the right EAC. An otoscopic examination showed a polypoid mass on the bony EAC, which was finally diagnosed as epidermal cyst after an initial misdiagnosis as EAC carcinoma. We report the rare, unique case with literature review.
