  • A 10-day-old, Holstein calf with facial mass of 10 cm in diameter at the forehead region referred to Veterinary Medical Teaching Hospital in Chungnam National University. The mass was soft and fluctuating swelling. It had normal skin and hair hanging forward from frontal region and was thought to contain cerebrospinal fluid. On the skull radiography, cauliflower like-irregular marginated, soft tissue opacity mass was identified craniodorsal to the frontal bone. The mass appeared as a cyst filled with anechoic fluid on ultrasonography. Soft tissue structures considered brain tissues were observed in the deep area of the mass. On the computed tomography, a large skull defect of left side frontal bone was found, and heterogeneous materials were exposed through the defect but exposure of cerebral meninges and brain tissue were not confirmative. On magnetic resonance imaging, herniated left brain parenchyma showed heterogenous T2 and T1 hyperinsensity. In the intracranium, T2 hyperinstense and T1 hypointense fluid was identified on the left side, instead of left cerebral parenchyma. Also leftward shift of right hemisphere and midline structure, including thalamus and midbrain, were observed. The definitive diagnosis was confirmed as a meningoencephalocele based on computed tomography and magnetic resonance imaging. The calf was euthanized and necropsy was performed. On necropsy, both hemisphere were developed unequally with different size. One side hemisphere was grown in the outside through 10 cm hole on the median plane.

  • 사지와 몸통의 연부조직 종양은 정형외과 의사가 직면할 수 있는 흔한 문제이다. 비록 연부조직 종양은 대부분 양성이지만 정형외과 의사는 양성과 악성 종양을 구별할 수 있는 특징을 알고 있어야 한다. 연부조직 종양의 임상적 특징 및 역학을 이해하게 되면 올바른 진단 및 수술적인 치료를 할 수 있게 된다. 종양의 크기와 깊이는 종양의 진단을 위해 가장 중요한 요소이다. 종양의 감별 진단을 하기 위해서 우선적으로 상세한 병력청취와 자세한 신체 검사가 필요하며, 이후 단순 방사선 촬영, 초음파, 자기공명영상(magnetic resonance imaging), 양전자 방출 단층촬영술(positron emission tomography), 컴퓨터 단층촬영(computed tomography), 뼈 스캔, 혈관 조영술 등의 다양한 영상 촬영법을 사용하여 종양을 진단하고 진단된 종양의 특성을 확인하여야 한다. 특히 초음파 검사는 외래에서도 쉽게 수행할 수 있어 유용하다. 그러나 검사자의 숙련도에 따라 검사 정확도의 차이가 발생할 수 있다는 단점이 있다. 종양의 생검을 통한 조직검사는 종양에 대한 모든 영상 검사를 시행한 후 최종적으로 시행하는 것이 원칙이다. 조직 검사를 시행할 때는 세심한 주의를 기울여야 하며, 최종적인 진단 후에는 치료를 위해 다각적인 접근을 시행하여야 하며 필요한 경우에는 경험 있는 근골격계 종양전문의사에게 의뢰하는 것이 필요하다.

  • We present a metastatic carcinoma from the breast to the neck soft tissue around common carotid artery, with a rare finding of voice change. A 60 year-old female patient presented with voice change for 7 months. Neck ultrasound revealed a soft tissue mass between internal jugular vein and common carotid artery. Result of fine needle aspiration biopsy was a metastatic carcinoma. Computed tomography and magnetic resonance image revealed $2.5{\times}3.0cm$ sized irregular marginated soft tissue mass in right lower neck encasing common carotid artery and internal jugular vein. Surgical resection was performed and pathologic result with immunohistochemical analysis confirmed the diagnosis of a metastatic invasive ductal carcinoma originated from breast.

  • A patient with actinomyces infection of the submandibular soft tissue was diagnosed by fine needle aspiration cytology (FNAC). A 38-year-old woman presented with a right submandibular mass which slowly grew in size over one month. Clinically and radiologically, the lesion was considered as tuberculous lymphadenitis or cellulitis. The polymerase chain reaction for tuberculosis was done by aspirated specimen but the result was negative. The smears of aspiration cytology showed characteristic colonies (sulfur granules) of actinomyces in inflammatory background. After antibiotic therapy for eight months, the patient has been well, showing no detectable mass. This patient was simply and rapidly diagnosed by FNAC and can avoid unnecessary surgical biopsy.

  • Soft tissue tumors of the foot have a low incidence rate, and most of them are symptom free, thus it is difficult to diagnose accurately. Herein, we report a 15-year-old male patient who had swelling without pain on the lateral margin of both feet. We performed excisional biopsy of the abductor digiti minimi via subtotal resection, following radiograph and magnetic resonance imaging. According to the histological analysis, hypertrophy of abductor digiti minimi was positive, and other soft tissue tumors were negative. Six months after the operation, normal appearance of both feet was maintained and the patient was satisfied with the result.

  • Rosai-Dorfman disease (RDD) is a benign proliferative histiocytic disorder of unknown etiology, which typically manifests as lymphadenopathy and systemic symptoms. Lymph node involvement is typical, but soft tissue RDD without nodal or systemic involvement is extremely rare. We report on a case of soft tissue RDD in a 16-year-old girl with a palpable mass on her buttock. It was firm, mobile, and discrete without tenderness. Excisional biopsy was performed, then RDD was confirmed histologically. RDD is a non-neo-plastic disease that should be considered in the differential diagnosis of other soft tissue tumors. While the optimal treatment for extranodal RDD remains controversial, surgical excision is typically curative.

  • 개화성 반응성 골막염은 드문 양성 섬유골성 증식으로 대부분 손의 짧은 관상골을 침범하고, 긴 관상골의 침범은 드물다. 저자들은 26세 남자에서 수술로 확진되었던 쇄골의 개화성 반응성 골막염 1예를 보고한다. 자기공명영상에서 병변은 높은 T2 신호강도를 보이는 연조직 종괴로 쇄골의 골막에서 기인하는 것으로 보였고, 주변의 골막거상과 종괴 주변의 연조직 부종이 관찰되었다. 조영증강 시 종괴의 내부는 강한 조영증강을 보였고, 쇄골의 골막을 따라서도 쇄골 둘레의 절반 이상을 둘러싸며 조영증강이 확인되었다. 연속된 단순촬영에서는 무기질 침착이 없는 연조직 종괴로 보이다가 한 달 이내에 빠른 속도로 연조직 종괴의 골화가 확인되었고, 고체형 골막반응이 동반되었다.

  • A 10-year-old castrated male Schnauzer (case 1) and a 13-year-old intact male Schnauzer (case 2) was referred with mass of left hind limb. We performed hemogram, serum chemistry, radiography, ultrasonography, computed tomography, fine needle aspiration and histopathology. The complete blood counts and serum biochemistry results were within the reference range. Radiography showed cutaneous mass with soft tissue density. The lesions of two dogs were revealed a definite marginated hyperechoic mass with vascularization in ultrasonography. Computed tomography showed an isodense mass in the left hind limb region with minimal contrast enhancing in case 1 and heterogenous enhancement in case 2. Cytology from ultrasonographic guided aspiration of the mass was suspected fibrous tissue-derived benign cell in two dogs. A surgical excision was performed in two dogs. In histological examination of the resected mass, cutaneous fibroma was revealed. The two patients were successfully treated by surgery and postoperative care. This report decribes and compares radiographic, ultrasonographic, computed tomographic, cytologic and histopathologic features of the cutaneous fibroma of two schnauzer dogs.

  • Malignant lymphoma in chest wall is a rare form of extranodal variety as occasionally localized tumor. The primary site is suggested from rib or soft tissue, but the incidence in rib is higher than soft tissue. The patient, a male, aged 32, noted a swelling and pain over the left lower posterior chest from 3 months prior to admission. Roentgenograms revealed bony destruction in left 9, & 19th ribs posteriorly and associated chest wall mass which was ill defined uncleared margination. Under diagnosis of malignant tumor, the operation was performed and the tumor mass resected widely with en bloc technique than the fascia lata was grafted at chest wall defect. The histology of specimen was disclosed as malignant lymphoma, non-Hodgkin`s diffuse lymphocytic poorly differentiated form. The radio-and chemotherapy were combined post-operatively and the complete remission is acquired.

  • This is a report of adenoid cystic carcinoma occurred in the palate in 30-year-old patient with a complaint of exophytic mass. The authors diagnosed it as adenoid cystic carcinoma by the clinical examination, radiographic findings and histopathological findings. The obtained results are as follows: 1. In clinical examination, asymptomatic exophytic mass of palate was observed. 2. In radiographic findings, soft tissue mass infiltrated the left maxillary sinus, nasal cavity, infraorbital fossa, hard palate, pterygopalatine fossa and pterygoid plate, and enhanced soft tissue mass was also observed in CT. 3. In histopathological findings, tubular and solid patterns of glandular structures were observed and the infiltration of tumor cells into the nerve fibers was also observed. 4. Two years after radical surgery, radiation therapy and chemotherapy, the perineural spread to orbital area was observed. 5. Much longer follow-up than 5 years is needed for early diagnosis of recurrence and distant metastasis.
