We report a case of intramuscular hemangioma in the subscapularis muscle and the resulting impairment of shoulder function in an adult patient. A nineteen-year-old female complained of shoulder pain and the development of a mass in the absence of previous trauma. Physical examinations, including lift-off and belly-press tests, showed abnormality. X-ray showed multiple calcifications in the front of the scapula. Magnetic resonance imaging showed a soft-tissue mass occupying almost the entire intramuscular portion of the subscapularis muscle. An arthroscopic examination excluded the possibility of a joint invasion, after which the entire mass was successfully removed by open excision. The displacement of the subscapularis by the mass was relieved after the surgery. Pathological diagnosis of the tissue confirmed a cavernous hemangioma. Both shoulder pain and function was improved after operation. There was no evidence of recurrence even at the 2-year follow-up. Rare forms of hemangioma adjacent to the shoulder joint could be successfully managed with surgical excision. Differential diagnosis, such as synovial chondromatosis, pigmented villo-nodular synovitis, and malignant sarcoma, should also be considered.

Retroperitoneal teratoma was described in a 20-month-old intact female ferret (Mustela putorius furo). Retroperitoneal mass about $8{\times}5$ cm in size was surgically removed and histopathologic examination was performed. Grossly, on cross section of the mass, the consistency was soft to firm and contained several cystic structures which are filled with dried keratinous material. Histologically, the retroperitoneal mass consisted of embryologically heterogeneous tissues that include skin, bone and cartilage, adipose tissue, respiratory epithelium, and exocrine pancreatic tissue. Based on the characteristic histologic features of the mass, a diagnosis of retroperitoneal teratoma was made. Adrenal gland or ovary was suspected as the origin of the tumor.

A 17-month-old boy was evaluated for a midline mass on his chin. The mass was anchored to the mentalis muscle with a stalk-like structure. The pathological diagnosis of the mass was rhabdomyomatous mesenchymal hamartoma. This is the first report of rhabdomyomatous mesenchymal hamartoma presenting as a midline chin mass in Korean pediatric patients.

A neutered male Maltese, 11-year-old, presented for hard mass at right flank suddenly. Patient vomited and had anorexia before the presentation, but it is improved after. On blood tests, there were no remarkable findings. On physical examination, firm mass ($2.9{\times}2.6cm$, firm) was detected. No remarkable finding was shown in radiography except for right upper-medial abdominal subcutaneous soft tissue mass. Punch biopsy was performed for histopathologic examination. During the punch biopsy, ice-cream stick ($11.5{\times}1.2cm$) appeared from the hole on right flank. Additionally gastric perforation was detected on ultrasonography. Emergency surgery was performed for the perforation. On histiopathologic examination of the mass, marked, diffuse, neutrophilic and mild eosinophilic dermatitis/cellulitis with no infectious agents was observed.

포충증은 주로 유구낭충에 감염된 환자에 larval cysticercoid stage때 soft tissue에 전이되어 이 cysticercus가 죽음으로써 변성되고 석회화를 일으켜 국소적 소견으로는 nontender mass, 그리고 X-ray 상 typical calcification을 일으키며 조직학적 소견으로는 fibrotic cyst속에 scolex의 hooks와 sucker를 볼 수 있다. 만약 cysticercosis가 두뇌속으로 전이된다면 두뇌의 침범된 부위의 국소증상이 나타날 수 있으며 예후는 매우 나쁘다. 조직학적 소견상 포충증으로 확진되면 환자를 입원시켜 전신을 검사하여 nontender mass가 만져지면 적출하여 주어야 한다. 저자들은 우측 안면부에 nontender mass를 주소로 하여 내원한 24세 남자에서 우측 안면부에 전이된 유구낭충증 1 례를 경험하였기에 문헌적 고찰과 함께 보고하는 바이다.

Purpose: Paragonimiasis is infectious disease occurred by Paragonimus Westermani, which invades into human body as a final host. Habitual eating the freshwater crab or crawfish unboiled is one of the reason of infection. Paragonimiasis raged in 1970s in Korea, Japan, China and other Asian countries but the incidence decreased rapidly. Once people eat infected second host, parasite penetrates the duodenal wall and migrates to the lung. During this migration period, the parasite can migrate to other organ, such as brain, spinal cord, liver and subcutaneous tissue, but the cases are rarely reported. The objective of our study is to present our experience of the ectopic migration of parasite to the subcutaneous tissue of the abdomen, which was easily treated with excision and Praziquantel medication. Methods: A 59-year-old woman who likes eating unboiled freshwater crab was diagnosed as Paragonimiasis 15 months ago. Her symptoms were fever and cough, and she was treated with Praziquantel medication. 3 months after discharge, she visited our hospital with left pleuritic chest pain, cough with fever, and palpable mass formation on left lower quadrant of the abdomen. Wedge resection of the left lung and Praziquantel medication was maintained for a week. Nevertheless, fever persisted after the treatment. The patient received total excision of the abdominal soft tissue mass, and the fever was relieved. Results: Pathologic findings of the mass showed multiple cyst and abscess formation with crystal structure which is suspicious parts of the parasite or calcified egg shells. Uncontrolled fever was relieved after the operation, and there was no evidence of recurrent Paragonimiasis and ectopic migration for 1 year follow up period. Conclusion: Ectopic migration of Paragonimus is rare, but multiple organ can be involved. Patient with Paragominiasis who was refractory in fever control after Praziquantel medication or surgical evaluation of the lung should be considered as ectopic migration of the Paragonimiasis.

목적: 신체 검사 및 초음파 검사를 통한 연부조직 종괴의 진단과 수술 후 조직검사를 통한 결과를 상호 비교, 분석하고 초음파 검사의 임상적 유용성에 대하여 고찰하였다. 대상 및 방법: 본원에서 연부조직 종괴에 대해 수술 전 초음파 검사를 시행하였고, 조직학적 생검을 통한 병리학적 검사로 확진을 받은 총 83명의 환자를 대상으로 한 후향적 검사를 시행하였다. 병력 청취와 신체 검사를 바탕으로 한 임상적 진단과 초음파 검사를 이용한 진단의 정확도를 조직학적 생검을 통한 확진을 바탕으로 상호 비교하였다. 결과: 초음파를 이용한 수술 전 진단의 정확도는 86.7%로 신체 검사만을 통한 진단에 비해 높은 정확도를 보였다. 초음파 검사의 경우 표피성 봉입낭종(epidermal inclusion cyst)인 경우 71.4%, 결절종은 85.7%, 지방종은 88.6%의 정확도를 각각 나타내었다. 반면 신체 검사와 병력 청취를 통하여 임상적 진단이 가능했던 경우는 총 54례로, 이 중 33례에서 병리적 진단과 일치하여 61.1%의 민감도를 보였다. 이 경우 종양별 진단 정확도는 결절종이 56.0%, 지방종이 67.9%로 나타났다. 결론: 초음파는 수술 전 연부조직 종괴의 진단에 있어 매우 유용한 진단 수단의 하나로 사료된다.

A 38-year-old man, who was diagnosed nasopharyngeal carcinoma (stage T4N2Mx) had rapidly growing lower neck mass (at level IV area) with local inflammation sign during concurrent chemoradiotherapy. After we performed Color Doppler sonography and fine needle aspiration biopsy of the neck mass, we differentiated neck soft tissue infection from tumor extension. Size of the mass decreased after antibiotics therapy. It was difficult to differentiate neck infection from tumor progression during treatment in naspharyngeal carcinoma.

활액육종은 발생기원이 명확히 밝혀지지 않은 간엽조직 기원의 악성 종양으로 골수로의 침범을 보이는 경우는 종양의 5-15%로 비교적 드물다. 24세 남자 환자가 6-7개월 전부터 시작되어 최근 2-3주 사이에 악화된 우측 하퇴부의 동통과 종창을 주소로 내원하였다. 자기 공명 영상에서 우측 경골 하단부에 경골을 둘러싸는 모양의 1.5x5x9 cm 크기의 종괴가 있었는데 경골 피질의 파괴가 있었고 골수는 T1 강조영상에서 골수의 지방 신호가 감소하고 조영증강을 보이는 등 부분적인 골수의 침범의 소견을 동반하고 있었다. 수술로 절제된 조직은 조직학적 검사에서 이상성 (biphasic) 활액육종으로 진단받았고 병변이 경골을 침범하고 있었다.

A 6-year-old female Pekingese dog, weighing 3.85 kg was presented with regurgitation, ptyalism, weight loss and anorexia. The dog was cachexic and severely dehydrated. Physical examination of the dog confirmed upper respiratory noise, which was classified as a stridor most apparent on inspiration, respiratory effort with stenotic nares. Upper respiratory signs were thought to be caused by brachycephalic syndrome. On the lateral thoracic radiograph, the caudal one third of the esophagus was visible as a soft tissue band. CT revealed oval-shaped, soft tissue attenuating mass in size of $2.3{\times}1.0{\times}1.1cm$ arising from caudal one third of the esophagus. The mass was protruding from esophageal wall to lumen and irregular margined with heterogenous contrast enhancement. The wall of cardia and fundus was focally thickened. Gastric lymph node was enlarged with contrast enhancing. On histopathologic examination, esophageal mass was confirmed as papillary adenocarcinoma, and the gastric sample showed the same result. In human, adenocarcinoma commonly occur in esophagus and cardia, but it has not been commonly reported in veterinary medicine. This report described computed tomographic features of adenocarcinoma of the esophagocardia region in a Pekingese dog with brachycephalic syndrome.
