This report describes a case of newly recognized congenital $M{\ddot{u}}llerian$ duct anomaly in a bitch. A fourteen-year-old, mixed breed bitch was presented with mild hematuria and mammary gland tumor. Complementary examinations were performed and abdominal ultrasonography revealed distended uterine horns and uterine tumor-like mass around the right ovarian area. Macroscopic examination showed the mass to be on the level of insertion of the right round ligament. The mass was cystic in nature, and had no communication with the uterine cavity. Histopathologically, the mass was identified as an accessory cavity lined by functional endometrium, which confirmed the diagnosis of accessory and cavitated uterine mass.

Branchial cleft cyst is the most common lateral neck cyst; the vast majority are of the second branchial cleft origin. This presumably reflects the greater depth and longer persistence of the second cleft, compared with the first, third, and fourth clefts. We experienced a 49-year-old male whose chief complaint was a abnormal mass of the left parotid gland area and neck. As a result of careful analysis of clinical, radiological, and histopathological findings, we diagnosed it as a second branchial cleft cyst in the neck and obtained results as follows: 1. In clinical examination, there was a 10×15㎝ sized, fluctuant painful mass in the left neck and parotid area. 2. In radiographic examination, a low echogenic mass with internal cystic change in the inferior parotid gland area was noted sonographically. Computed tomograph showed a 3×4㎝ sized, well-defined cystic mass with heterogenous solid component in the anterior border of sternocleidomastoid muscle. MRI revealed 5×6㎝ sized, well-marginated multi separated mass in the same area. 3. In histopathological examination, lining of cyst was stratified squamous epithelium with typical lymph node pattern and inflammatory cell infiltration.

목적 : 3T MR 기기를 이용하여, 췌장 주위에 발생한 낭성 종양에 대하여, 생체내, 그리고 생체외 생체내 자기공명분광법(magnetic resonance spectroscopy: MRS)를 획득한 후, 생체외 핵자기공명 (nuclear magnetic resonance, NMR) 스펙트럼을 기준으로 비교함으로써, 낭성 종양의 감별 진단에 있어 MRS의 적용 가능성을 알아보고자 하였다. 대상 및 방법 : 췌장 주위에 발행한 12예의 낭성 종양(점액성 낭성 종양=5, 췌담관내 유두종=5, 가성 낭종=1, 및 림프관종 n=1)을 대상으로 3.0T 생체내, 생체외 양성자 MRS 및 9T NMR 스펙트럼을 획득하였다. NMR의 피크와 상응하는 생체내, 생체외 양성자 MRS에서 관찰되는 피크의 존재유무를 알아보았으며, 특정 질환을 예측하는 피크에 대하여 알아보았다. 결과 : 생체내 MRS는 NMR과 민감도 29.6%, 특이도 82.6% 그리고, 67.7%의 정확도를 보였으며 (p=0.096, McNemar test), 생체외 MRS는 생체내 MRS는 민감도 57.1%, 특이도 92.6%, 그리고, 82.3%의 정확도를 보였다 (p = 0.362, McNemar test). 질병간의 스펙트럼의 차이는 NMR에서 췌담관내 유두종의 경우에서 점액성 낭성 종양에 비해 3.5-4.0 ppm에서 유의하게 많은 피크를 보였다 (p=0.026). 결론 : 결론적으로, NMR 이용한 화학물질 분석은 낭성 종양의 감별 진단에 도움이 될 가능성이 있는 기법으로 생각되지만, 생체내 및 생체외 MRS는 임상에 적용되기 위해서는 많은 기술적 발전을 필요로 하는 것으로 생각된다.

폐의 저악성 점액성 낭종은 보고된 예가 매우 드물며 기관지성 낭종 및 뮤신을 분비하는 기관지폐포암 형태의 선암과 감별이 필요하다. 63 세의 여자환자로서 흉부단순촬영 사진에서 우측 폐하엽에서 종괴가 관찰되었다. 술전 경피생검상에서 기관지폐포암으로 진단되었고 우측 폐하엽 절제술 및 임파절 제거술을 시행하였다. 절제된 폐내에서 다양한 크기의 다발성 낭성 종괴들이 보였고 종괴내에는 점액으로 채워져 있었다. 현미경상에서 낭종은 키가 큰 주상구조의 점액성 상피세포들로 구성되어 있었고 한정된 일부분에서 기관지폐포암양 병소가 관찰되었으나 기관지폐포암과 비교하여 세포의 비정형성(atypism)은 부족하였다. 수술후 환자는 합병증없이 퇴원하였고 12개월 추적관찰에서 재발이나 원격전이 소견은 보이지 않았다. 폐의 저악성 점액성 낭종은 술후 예후가 상당히 좋은 것으로 보고 되고 있으며 폐에서 발생하는 다른 신생물과는 감별이 필요할 것이다.

9 년령 암컷 콜리견이 복부 팽만, 식욕 부진 및 변비를 주증으로 본원에 내원하였다. X-ray, 초음파 및 CT 검사를 통하여 복강내 연부조직종괴를 확인하였으나 세포학적 검사에서 종양 세포는 관찰 할 수 없었다. 탐색적 개복술을 계획하였다. 크고 둥근 모양의 종괴가 우측 자궁각에 위치하는 것을 확인하고 난소자궁적출술을 실시하였다. 종괴의 크기는 $40{\times}25{\times}18$ cm 였으며 무게는 9.5 kg 이었다. 조직학적 검사를 통해 낭상자궁내막증식증(CEH)으로 진단하였다. CEH는 자궁 내용물이 감염되거나 자궁 축농증으로 이어짐에도 불구하고 임상 증상이 없는 경우가 많으므로 정확한 진단이 어렵다. 본 증례는 자궁 축농증을 동반하지 않은 매우 큰 크기의 국소성 낭상자궁내막증식증의 드문 예이다.

In case of lateral cervical cystic lesions, the differential diagnoses include branchial cleft cyst(BCC), teratoma, dermoid, hemangioma and lymphangioma etc. But sometimes metastatic cystic lymph nodes may exist in lateral neck. In such circumstance, the primary lesions are known to stem from oropharynx, nasopharynx, salivary and thyroid gland etc. A-66-year-old-male came to our clinic, due to the lateral cervical mass for 5 years. We performed the neck CT, sonography and sono-guided FNAC. He was initially diagnosed with the benign cyst such as BCC. We performed the excisional biopsy on left level II, but the pathologic report was revealed as metastatic papillary thyroid carcinoma(PTC). And then he received the total thyroidectomy with neck dissection. The final diagnosis was cystic metastasis from PTC. We learn a valuable lesson form this case in the following. Even if the simple cervical cyst is presumed with radiology and clinical pattern, more careful considerations on the basis of history and radiologic findings are mandatory.

Auricular endochondral pseudocyst is a very rare, benign intracartilaginous cystic lesion which most commonly presents as a cystic mass in the anterior plane of the auricle. We present a case report of a 48-year-old man with a fluctuating lesion of 3 week's duration on the left auricle, with no specific history of trauma or disease. Initial incisional drainage revealed an abundance of serous fluid, which quickly recurred. Surgical removal of the hypertrophic perichondrium forming the pseudocyst anterior wall and ear cartilage curettage was carried out with intraoperative absolute alcohol sclerotherapy, followed by compression dressings. The auricle healed uneventfully, with a good final cosmetic result and no recurrence within a 6-month follow-up period. We report this unusual case as the first in Korean plastic surgery with a review of the literature.

We report on a rare case involving a 23-year-old female patient with mediastinal cystic mass complicated with acute pericarditis and cardiac tamponade. Pericardial fluid demonstrated lymphocyte-predominant exudate and the level of carcinoembryonic antigen (CEA) was unexpectedly elevated. Successive aspiration of mediastinal cystic mass revealed a very high level of CEA (>100,000 U/mL) and carbohydrate antigen 19-9 (>15,000 ng/mL). This patient was clinically diagnosed as an infected bronchogenic cyst complicated with pericarditis and cardiac tamponade. The treatment resulted in alleviation of her symptoms.

Synovial cysts of the cervical spine, although they occur infrequently, may cause acute radiculopathy or myelopathy. Here, we report a case of a cervical synovial cyst presenting as acute myelopathy after manual stretching. A 68-year-old man presented with gait disturbance, decreased touch senses, and increased sensitivity to pain below T12 level. These symptoms developed after manual stretching 3 days prior. Computed tomography scanning and magnetic resonance imaging revealed a 1-cm, small multilocular cystic lesion in the spinal canal with cord compression at the C7-T1 level. We performed a left partial laminectomy of C7 and T1 using a posterior approach and completely removed the cystic mass. Histological examination of the resected mass revealed fibrous tissue fragments with amorphous materials and granulation tissue compatible with a synovial cyst. The patient's symptoms resolved after surgery. We describe a case of acute myelopathy caused by a cervical synovial cyst that was treated by surgical excision. Although cervical synovial cysts are often associated with degenerative facet joints, clinicians should be aware of the possibility that these cysts can cause acute neurologic symptoms.
