  • 증식성 모낭 종양은 모낭 말단부위의 외근모초에서 기원하는 드문 종양이다. 악성 변화는 드물지만 갑작스러운 크기의 증가, 침윤성 성장 및 두피 이외에서 종양의 발생 등은 악성 증식성 모낭 종양을 시사한다. 병리조직학적으로 핵의 이형성, 다형성 및 유사분열 소견은 악성증식성 모낭 종양의 특징이다. 악성 증식성 모낭 종양은 재발 및 전이가 보고되고 있어 정상조직을 포함한 충분한 절제와 추적관찰이 요구된다. 53세 남자 환자의 우측 제 5수지 원위 지골에 7년전 발생한 종양을 중위 지이하 절제술 후 병리조직검사상 악성 증식성 모낭 종양으로 진단되었고, 환자가 외래로 더 이상 방문하지 않아 재발과 전이를 확인할 수 없었다.

  • Purpose: Nipple reconstruction is an important step in breast reconstruction after mastectomy. There are considerable number of reconstructive methods developed over the past years. Each of these has not only its own special advantages, but also limitations. Therefore, no single method has become the overwhelming favorite. Sometimes it seems to be compromised when the nipple must be located directly over a linear scar. Methods: A 48-year-old female patient received a central lumpectomy with circumareolar resection of the nipple areolar complex 4 months ago. The newly designed nipple must be positioned directly astride a scar. We drew two equal-sized rectangular flaps sharing a common limb on a transverse scar and the result was two opposing plow form. Each flap size was about 1.3 cm wide and 2.5 cm long. First we elevated the flap from the distal part at a deep dermal plane, then deepened the level of dissection to raise the dermal-fat flaps. The donor site could be closed directly without any dog-ear deformity. Then we folded down the elevated flaps and loosely sutured skin with nonabsorbable materials. Each flap inner side was approximated side by side. Finally we made new natural nipple with 6 mm projection. We applied tattooing in the areola area with micropigmentation device after three months. Results: After ten months of follow-up periods, the nipple projection was stable and symmetric. The nipple projection was 3.1 mm, compared with 2.8 mm for the opposite nipple. Conclusion: Our experiences shows that this double opposing plow flap is a particularly useful and simple technique when there is a traverse scar crossing the center of the proposed nipple area.

  • Purpose: Many advances have been made in lower eyelid reconstruction surgical procedures after tumor ablative therapy. These include skin grafts, local flaps, free flaps, and skin expansion. When a full-thickness defect of the lower eyelid is reconstructed with many free flaps, ectropion and deformity of the medial and lateral canthal areas are common late complications caused by gravitational descent. The radial forearm free flap is widely used because of its lack of bulk, ease of dissection, malleability, and hairlessness. This report introduces a novel method for preventing ectropion using a composite radial forearm free flap reconstruction and palmaris longus suspension technique. Methods: A 70-year-old man had a malignant melanoma on his left lower eyelid. The patient was referred to our department after a biopsy confirmed the initial diagnosis. A full-thickness wide resection with a 25 mm free margin was performed, and a $5{\times}8cm$ radial forearm flap was elevated with a vascularised palmaris longus tendon. The palmaris longus tendon was fixed to the medial and lateral orbital rim perisoteum and the deep temporal fascia. The buccal mucosa was grafted to reconstruct the inner conjunctival layer. The pedicle vessels were anastomosed to the left superficial temporal artery and vein. Results: The postoperative clinical course was uneventful. The flap showed good texture and color match. No ectropion was noted 14 months after surgery and the tumor did not recur. The patient was quite satisfied with the final outcomes. Conclusion: Use of a radial forearm free flap and the palmaris longus tendon is an effective method for a full-thickness lower eyelid reconstruction.

  • Background: Fibula free flap mandible reconstruction is the standard procedure after wide resection of the mandible. Establishment and maintenance of normal occlusion are important in mandible reconstruction both intraoperatively and after surgery. However, scar formation on the surgical site can cause severe fibrosis and atrophy of soft tissue in the head and neck region. Case presentation: Here, we report a case of severe soft tissue atrophy that appeared along with scar formation after mandibular reconstruction through the fibular free flap procedure. This led to normal occlusion collapse after it was established, and the midline of the mandible became severely deviated to the affected side that was replaced with the fibula free flap, leading to facial asymmetry. We corrected the malocclusion with a secondary operation: a sagittal split ramus osteotomy on the unaffected side and a sliding osteotomy on the previous fibula graft. After a healing time of 3 months, implants were placed on the fibula graft for additional occlusal stability. Conclusion: We report satisfactory results from the correction of malocclusion after fibula reconstruction using sliding fibula osteotomy and sagittal split ramus osteotomy. The midline of the mandible returned to its original position and the degree of facial asymmetry was reduced. The implants reduced difficulties that the patient experienced with masticatory function.

  • Background: The resection of head and neck cancer can result in postoperative defect. Many patients have difficulty swallowing and masticating, and some have difficulty speaking. Various types of flaps are used for palatal reconstruction, but flap selection remains controversial. Therefore, our study will suggest which flap to choose during palatal reconstruction. Methods: Thirteen patients who underwent palatal reconstruction from 30 January, 1989 to 4 October, 2016 at our institution. Size was classified as small when the width was < $4cm^2$, medium when it was $4-6cm^2$, and large when it was ${\geq}6cm^2$. Based on speech evaluation, the subjects were divided into a normal group and an easily understood group. After surgery, we assessed whether flap selection was appropriate through the evaluation of flap success, complications, and speech evaluation. Results: Defect size ranged from $1.5{\times}2.0cm$ to $5.0{\times}6.0cm$. In four cases, the defect was in the anterior third of the palate, in eight cases it was in the middle, and there was one case of whole palatal defect. There were three small defects, two medium-sized defects, and eight large defects. Latissimus dorsi free flaps were used in six of the eight large defects in the study. Conclusion: The key to successful reconstructive surgery is appropriate selection of the flap with reference to the characteristics of the defect. Depending on the size and location of the defect, the profiles of different flaps should be matched with the recipient from the outset.

  • Sebaceous carcinoma is a malignant neoplasm that usually arises in the sebaceous glands of the eyelids. Its pathogenesis is unknown; however, irradiation history, immunosuppression, and use of diuretics are known risk factors. The mainstay of treatment for sebaceous carcinoma of the eyelid is wide surgical resection with a safety margin of 5 to 6 mm, which often results in full-thickness defects. The reconstruction of a full-thickness defect of the eyelid should be approached using a three-lamella method: a mucosal component replacing the conjunctiva, a cartilage component for the tarsal plate, and a flap or skin graft for the skin of the eyelid. In this case, a full-thickness defect of the upper eyelid was reconstructed after tumor removal using a combination of a nasal septum chondromucosal composite graft and a forehead transposition flap, also known as a "Fricke flap." The flap was designed to include a line of the eyebrow on the lower margin of the flap to replace the eyelash removed during tumor excision. The wound healed completely, without any early or late complications, and the outcome was satisfactory.

  • 비안와주변부 피지샘암종은 매우 드문 암으로 초기에 추정진단하기 어려울 수 있다. 진단은 조직검사로 이뤄지게 되며, 깊은 경계를 침범할 수 있으므로 절제생검을 통한 진단이 필요하며, 종양의 경계를 5mm기준으로 시행하는 광범위절제술 및 동결절편으로 절제 가능하다. 전이여부에 따라 경부림프절곽청술 및 보조방사선 치료가 필요할 수 있다. 또한 뮤어-토레증후군의 감별을 위한 소화기 내시경 및 컴퓨터 단층 촬영이 필요할 것이다. 저자들은 본 증례를 통해 비호발 연령과 비호발 위치에 발생한 피지샘암종을 보고하고자 하였으며, 비안와주변부 피지샘암종에 대한 더 많은 증례 분석이 초기 진단을 위해 필요할 것으로 생각한다.

  • 개에서 자연발생한 유선종양으로부터 채취, 배양된 세포주 2개를 확립하고 특성을 분석하였다. 9세 령의 퍼그 종 개와 동일연령의 토이푸들 종의 개에 발생한 종양을 무균 상태를 유지하여 수술적으로 채취한 후 primary culture를 실시하였다. 두 종양의 조직병리검사에서는 각각 선암종과 혼합암종이 진단되었으며, 이후 두 마리 모두 전이로 인해 폐사하였다. 배양된 종양세포는 1년 이상의 기간 동안 60회 이상 계대를 반복하면서 형태학적으로 일관성을 유지하였고, 특성분석을 위해 광학현미경검사, 성장곡선 산출, 배가 시간 계산, 누드 마우스에 이종이식, 면역조직 화학검사를 실시하였다. 각 세포주는 다각형의 긴 세포형태를 보였으며, 세포질 연결을 형성하였으며, 배가 시간은 각각 47.1 시간과 18.6 시간이었다. 암컷 누드마우스의 등 부위에 피하이식 후 4주 이내에 10마리 중 9마리에서 촉진이 가능한 종괴의 형성이 확인되었으며, 면역조직화학검사 시 한 세포주에서는 keratin과 cytokeratin 8에서 다른 세포주에서는 smooth muscle actin과 cytokeratin 8에서 강한 염색성이 확인되었다. 두 세포주는 개의 유선종양의 시험관내, 체내 연구에 있어 모두 유용하게 사용될 수 있을 것으로 생각된다.
