심한 복부팽만과 호흡 곤란 증세를 보이는 10살의 요크셔 테리어가 내원하였다. 방사선과 초음파 검사로 우심방과 주폐동맥에 인접한 대동맥 주위로 고에코성의 큰 종괴를 확인하였다. 확인된 종양은 심장 기저부 주위에 존재하는 확장성 종양으로 삼첨판 역류, 대량의 복수와 간정맥 확장을 동반한 간종대와 같은 우심 부전 소견을 보였다. 전산화단층촬영법으로 확인된 이 종괴는 전대정맥에서 후대정맥까지 위치한 심장 기저부 주위에 존재하는 크고 비균질성을 띤 종괴였다. 이 종괴는 전대정맥, 심장, 후대정맥 및 흉벽까지 침습되어 있었으며, 세침흡입술을 통한 잠정적인 진단은 Chemodectoma였다. 본 증례로 다양한 진단 영상학적 수단을 통한 심기저부 종양에 대한 특징 및 역할을 알 수 있었다.

10년령의 수컷 푸들이 복부팽만, 등쪽 몸통 부위 탈모, 간비대와 혈청 알칼리인산분해효소의 지속적인 상승으로 전북대학교 수의과대학 동물병원에 내원하였다. 간 생검 및 미세침흡인세포 검사법과 PAS 염색을 실시한 결과 공포성 간병증 및 간세포에 글리코겐이 침착된 것을 확인 하였다. ACTH 자극 시험 실시 전 후 코티솔 및 부신과 관련된 성 호르몬의 농도를 측정하였다. 측정결과 안드로스텐디온, 프로게스테론 및 수산화 프로게스테론의 상승을 관찰할 수 있었으며 코티솔농도는 정상 범위내에 존재하였다. 진단은 성호르몬과 관련된 비정형의 부신피질 기능 항진증으로 내렸으며 치료는 트릴로스탄으로 하였다. 치료 8주 후 등 부위의 탈모를 포함한 임상증상들이 개선되었다.

6 년령의 수컷 시츄 견이 복부 팽만을 주 호소로 내원하였다. 복부 방사선 검사와 초음파 검사에서 많은 양의 액체를 포함하고 있는 연부조직 밀도의 종괴가 발견되었다. 종괴의 세포학적 검사를 위해 초음파 유도 세침흡인을 실시하였으며, 세포학적 검사 결과 섬유화가 동반된 육아조직이 의심되었다. 종괴의 확인과 수술적 제거를 위해 진단적 개복술을 실시하였다. 개복시 원위 공장부위에 인접한 장간막의 뿌리에서 유래한 종괴가 확인되었고 종괴는 원위공장 부위에 부착되어 있었다. 종괴와 부착 부위의 분리가 어려웠기 때문에 종괴와 부착 부위를 모두 수술적으로 제거하였으며 장문합술을 실시하였다. 종괴의 조직병리학적 검사 결과 저 악성도 점액육종이 진단되었으며, 종양 세포는 알시안 블루 염색에 양성 반응을 보였다. 추가로 실시한 Ki67 항체를 이용한 면역조직화학 염색 결과 Ki-67 지수는 2.5 였다. 환축은 절제술 실시 후 현재까지 30개월 동안 전이와 재발의 증거 없이 살고 있다.

프로게스테론 제제를 복용해 오던 12세령의 암컷 잡종 견이 복부 종괴의 평가를 위해 내원하였다. 복부 초음파 검사와 방사선 검사를 통해 확장된 자궁과 관련된 종괴를 확인하였다. 혈청 화학 검사에서는 고글로불린혈증이 나타났으며, 전기영동 검사상 급성 염증 패턴으로 판단되었다. 초음파 유도하에 종괴의 세침흡인을 실시하였으며 세포학검사를 통해 선암종이 진단되었다. 탐색적 개복을 실시하였으며 장구체의 종괴를 발견하여 자궁과 함께 종괴를 제거하는 수술을 실시하였다. 조직병리 검사결과 자궁 선암종이 진단되었으며 종양세포의 에스트로겐 수용체와 프로게스테론 수용체 발현 여부 평가를 위해 면역 염색을 실시하였다. 면역염색결과 종양세포는 두 항체에 대해 음성 결과를 보였으며, 정상 간엽세포에서만 양성 결과가 나타났다. 수술 후 1주일에 재검을 위해 내원하였는데 컴퓨터 단층촬영 검사결과 폐 전이가 확인되었다. 환자는 수술 후 40일경에 폐사하였다.

A 9-year-old, female, Maltese Dog(2.15 kg of body weight) was referred to the Veterinary Medical Teaching Hospital, Chungnam National University with cervical masses, abdominal masses and petechia. Physical examination showed masses in mandibular, prescapular, inguinal, popliteal lymph node and abdominal subcutaneous hemorrhage. This case was diagnosed as the multicentric lymphoma by physical examination, laboratory examination, radiography, ultrasonography, CT, fine needle aspiration and histopathologic examination. This dog was treated by low-budget protocol with lomustine and prednisolone. The dog show that response duration and survival time is 143days and 263 days, respectively.

A 1.35 kg, three-year-old, female, Yorkshire terrier was referred to the veterinary medical teaching hospital of Chungnam National University with an alopecia, scale, polydipsia and polyuria. During hospitalization, the patient revealed swelling and pain of all four foot pads. The hematology indicated nonregenerative anemia. Blood serum chemistry revealed elevation of BUN, serum creatinine and phosphorus contents. Radiographs of feet revealed increased radiodensity in the soft tissue of the foot pad. In ultrasonographs of abdomen, kidneys showed diffusely echodense renal cortex with loss of the normal corticomedullary boundary. Fine needle aspiration of the swollen pad cysts contained a amorphous basophillic chalky, white and pasty material. The culture result was negative for bacteria. In conclusion, it was diagnosed as metastatic calcinosis circumscripta secondary to chronic renal failure. An oral charcoal absorbent and aluminum hydroxide were used to treat this condition. After six weeks treatment, hyperphosphatemia was corrected and metastatic calcinosis circumscriptawas not presented any more.

Lymphoma is the most common hematopoietic malignancy in dogs. Diagnosis of lymphoma is classically performed by morphological assessment and immunohistochemistry. But some cases in the early stage are difficult to distinguish and need more objective and accurate methods. So, Polymerase chain reaction (PCR) for antigen receptor rearrangements (PARR) and flow cytometric immunophenotype of lymphoma have been developed continuously. In this study, we performed these two methods to classify lymphoma type in 3 cases. According to PARR analysis, B cell origin lymphoma was diagnosed in two of three cases by testing PBMC and lymph node. All fine needle aspiration (FNA) samples of lymph nodes had high expression of CD21 on >88% of total cell population and PBMC samples also showed high expression of CD21 on >30% of total lymphocytes in those two cases, while the expression of CD3, CD4 and CD8 was absent. These results suggest that concurrent use of PARR and flow cytometric immunophenotype is more effective and valuable tool for the diagnosis and monitoring of canine lymphoma patients.

Clinical features of masticator-space abscess (MSA) are very similar to those of parotitis or temporomandibular disorder (TMD), making early differential diagnosis difficult. Local causes of MSA include nerve block anesthesia, infection after tooth extraction, and trauma to the temporomandibular joint (TMJ); the systemic cause is immunodeficiency. Odontogenic causes account for most etiologies, but there are also unusual causes of MSA. A 66-year-old male patient visited the emergency room (ER) presenting with left-side TMJ pain three days after receiving an acupressure massage. He was tentatively diagnosed with conventional post-trauma TMD and discharged with medication. However, the patient returned to the ER with increased pain. At this time, his TMD diagnosis was confirmed. He made a third visit to the ER during which facial computed tomographic (CT) images were taken. CT readings identified an abscess or hematoma in the left masticator space. After hospitalizing the patient, needle aspiration confirmed pus in the infratemporal and temporal fossa. Antibiotics were administered, and the abscess was drained through an incision made by the attending physician. The patient's symptoms decreased, and he was discharged.

Ultrasound images are noninvasive, can be observed in real time, have no radiation exposure, do not cause pain, and are not restricted in use depending on the patient's prosthetic implant or medical condition. Since the use of ultrasound in the dental field was first applied for tooth preparation in 1957, the use of diagnostic ultrasound for the first time in 1963 has been reported. Currently, it is used in the diagnosis of soft tissue lesions such as malignant tumor or salivary gland disease, fine needle aspiration test, temporomandibular joint disease, lymph node metastasis, measurement of muscle thickness and inflammatory diseases, differentiation of periapical cyst and granulation tissue, measurement of periodontal tissue thickness. The ultrasound image can be visualized in real time. The clinician can explain the structure to the patient while consulting the patient and consult the patient. When injecting the drug into a specific site or aspirating a specific site or substance, So that it can be confirmed and practiced. Recently, ultrasonic equipment specialized in the dental field has been developed and marketed, and it is expected that the use of ultrasonic waves will become active in the dentistry. In the future, development of popular equipment with size and frequency suitable for dental diagnosis and various researches on maxillofacial ultrasonic anatomy. If clinical studies are continuously carried out to demonstrate efficacy, ultrasound is expected to aid in accurate diagnosis and treatment throughout the dentistry.

Follicular bronchitis/bronchiolitis is pathologically characterized by peribronchiolar lymphoid follicles, which is one of reactive pulmonary lymphoid disorders. It is associated with 1) the result of infections such as mycoplasma, chlamydia etc., 2) immunodeficiency syndromes, 3) connective tissue diseases such as rheumatoid arthritis and Sjogren's syndrome and 4) local or systemic hypersensitivity reaction. And it can be also developed without obvious causes and associated diseases(idiopathic). Radiologically it represents as bilateral interstitial patterns of pulmonary infiltrates. In this case, a 49 year-old woman was presented with intermittent cough and sputum. On chest X-ray and CT, $5\times4$ cm sized mass in right upper lobe and paratracheal lymphadenopathies were detected, by which lung malignancy was suspected. Bronchoscopy, trans bronchial lung biopsy and transthoracic needle aspiration showed non-specific findings only. After right upper lobectomy, we could confirm a case of follicular bronchiolitis which presented as an unusual mass-like radiologic finding.
