A rare case is described of an intrathyroidal branchial cleft-like cyst in neonate. The patient was a newborn girl with a mass in the left lateral neck. The ultrasonography and computed tomography revealed a cystic lesion in the left thyroid. The lesion was enucleated surgically from the thyroid. Histologically, the cyst was lined by squamous or columnar epithelium and contained inflammatory cell infiltraion, thyroid and parathyroid tissue. The patient has been doing well without any evidence of thyroid dysfunction for 15 months.

A 53 year-old woman visited to our hospital due to increased hemoptysis for 4 days. The chest X-ray showed solitary pulmonary nodule on right upper lobe and computed tomography of chest demonstrated mass on posterior segmental bronchus of right upper lobe. Bronchoscopic examination revealed that this segmental bronchus was completely obstructed by a yellow and brownish mud like mass, which was identified as an aspergilloma by pathologic examination. Patient had undergone bilobectomy because of persistent hemoptysis. Tracheobronchial apergillosis in an immunocompetent person is very rare disease. then, we report this case with review of the Korean literature.

Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.

목적: 모반양 기저세포암 증후군 (Nevoid basal cell carcinoma syndrome) 또는 골린-골츠 증후군은 한국에서는 흔하지 않은 증후군으로 주로 상염색체 우성으로 유전하고 다기관 장애가 나타날 수 있으며 높은 표현율과 다양한 표현도를 특징으로 한다. 모반양 기저세포암 증후군의 진단 기준에는 다발성 기저세포암, 이소성 석회화(ectopic calcification), 손 또는 발바닥 오목 (palma or plantar pits), 치성 각화 낭종(odontogenic keratocysts), 가족력 및 골격계, 신경계, 안, 비뇨생식계 및 심장혈관의 이상 등이 있다. 본원에서 주로 두부의 다발성 기저세포암을 가진 모반양 기저세포암 증후군 환자를 경험하여 보고하고자 한다. 방법: 환자는 2007년 4월 두부의 색소성 모반으로 피부과에서 시행한 펀치 생검에서 기저세포암을 진단받고 의뢰되었으며, 이후 2009년 7월까지 14회의 추가적인 절제 및 조직 검사를 시행하였다. 환자는 갑상샘 유두암종의 재발로 인해 갑상샘 절제술을 2회 시행한 과거력이 있었으며 이학적 검사와 일반 혈액, 소변, 간 기능 및 갑상선 기능 검사를 시행하였고, 흉부와 늑골 방사선 검사, 심전도와 안면부 및 두부 컴퓨터단층촬영과 유전자 검사를 시행하였다. 결과: 두부와 안면부에서 절제한 27개의 병변 중 23개(85%)가 기저세포암으로 진단되었으며, 치성 각화 낭종과 대뇌겸 석회화, 이학적 검사에서 손바닥 오목이 발견되었다. 하복부 초음파에서 난소 낭종이 발견되었으나 조직 검사는 시행되지 않았다. 결론: 한국에서 모반양 기저세포암 증후군에 대한 연구는 주로 치과와 피부과 영역에서 국한되었으며, 특히 치과 영역에서의 보고는 치성 각화 낭종 및 손바닥 오목에 초점을 둔 것이 대부분이었다. 이에 본원에서는 주로 두부의 다발성 기저세포암을 가진 모반양 기저세포암의 환자를 경험하였으며, 초기에 발견된 작은 병변의 제거 시 2mm의 정상 조직을 포함하여 절제하였어도 3년간의 경과관찰 중 재발없이 좋은 결과를 얻을 수 있어 이를 보고하는 바이다.

A 12-year-old female mixed breed dog receiving a progesterone drug was referred for evaluation of an abdominal mass. Abdominal radiography and ultrasonography revealed a swollen uterus and an associated mass. Serum chemistry revealed hyperglobulinemia consistent with acute inflammation based on the results of serum protein electrophoresis. Fine needle aspiration of the mass guided by ultrasonography was performed for cytological evaluation. The cytological impression was consistent with adenocarcinoma. Exploratory laparotomy identified a uterine body mass, which was surgically removed for histopathology. Histology of the mass identified a uterine adenocarcinoma. Immunochemistry using anti-estrogen and progesterone receptor antibodies was performed and neoplastic cells were negative to both antibodies while some normal elements were reactive to both of them. Computer tomography demonstrated evidence of metastatic disease in the lung one week after the surgery and the dog died about 40 days after surgery.

The term tracheal bronchus refers to an abnormal bronchus that comes directly off of the lateral wall of the trachea (above the carina) and supplies ventilation to the upper lobe. Tracheal bronchi occur almost exclusively on the right trachea and are associated with other congenital anomalies. In addition, tracheai bronchus may be related to other inflammatory conditions with persistent wheezing, such as recurrent pneumonia, chronic bronchitis and bronchiectasis, which is a result of the relatively poor local drainage of the involved bronchi. An infant with recurrent wheezing is likely to be a challenge for a clinician in the evaluation of the etiology of airway obstruction and in the differential diagnosis of wheezy breathing. The authors report a case of an 8-month-old female infant with a ventricular septal defect, who presented with stridor and recurrent respiratory infection and finally was finally diagnosed with a tracheal bronchus using computed tomography and a bronchoscopy. Therefore, tracheal bronchus should be included in the differential diagnosis of any child who presents with chronic or recurrent respiratory tract symptoms such as coughing, wheezing, stridor and recurrent respiratory infection, particularly in children with other congenital deformities.

A three-year-old Beagle dog was presented with the neck mass. Mass was located at ventral part of the mandible. The dog showed excessive drooling. Sialocele with calculi was evaluated based on physical exam, radiographs, ultrasonography, and computed tomography. Salivary gland resection was performed. Histopathological examination confirmed sialoadenitis concurred with sialocele.

Three dogs were presented with a history of dyspnea and cough. Physical examination, blood analysis, bronchoalveolar lavage and radiography of three dogs were evaluated. And additionally, computed tomography and lung biopsy were performed on one dog. They showed normal laboratory examination results. The radiographic findings noted alveolar and bronchointerstitial infiltration with bronchiectasis. For one dog, nodules scattered throughout both lung fields on survey radiographs were confused with pulmonary neoplasia, so CT scan was used to rule out neoplasia. Bronchoalveolar lavage revealed abnormally high levels of eosinophils in all dogs. On histopatholgic exam, eosinophilic bronchiolitis and eosinophilic and histiocytic alveolitis were confirmed. Consequently, all dogs were diagnosed as eosinophilic bronchopneumopathy. Symptoms regressed dramtically within a few days after treatment with oral corticosteroids. Radiographs and CT scan are useful for diagnosis and prognosis of eosinophilic bronchopneumopathy.

Femoral avulsion fracture of posterior cruciate ligament (PCL) is rare, especially in adult. We experienced a case of femoral bony avulsion fracture of PCL. The patient was seventy one year old man with limitation of motion in the knee joint due to previous trauma and he was injured by fall down from 2 m height. We took CT scan and MRI study. We treated with arthroscopic repair technique using transfemoral two wire sutures. Second look arthroscopy was done for removal of the wires at postoperative one year.

A 5-year-old male German shepherd dog was presented with a 4 day-history of anorexia and depression. Abdominal radiographs showed a large soft tissue mass and loss of serosal detail. Ultrasonographs revealed splenomegaly with the lacy pattern parenchyma, perivenous hyperechoic region at the splenic hilum, and loss of splenic venous flow. Computed tomographic findings included the enlarged non-enhanced spleen except perivenous region at the splenic hilum and a whirled soft tissue mass at the splenic hilum. Exploratory laparotomy confirmed the diagnosis of splenic torsion. Ultrasonographic findings including lacy appearance, hyperechoic perivenous echogenicity and absence of splenic blood flow and CT findings including no or minimal enhancement of the spleen and a whirled appearance of splenic pedicle could be useful for diagnosing isolated splenic torsion in the dog.
