Nasolabial cyst is a rare non-odonotogenic, soft-tissue, developmental cyst arising inferior to the nasoalar region of the face. The most common clinical finding of the nasolabial cyst is that of a slowly enlarging asymptomatic swelling typically without radiographic abnormalities. This case report describes a 25-year-old man in which the clinicopathologic findings and an erosive finding on the computed tomographic scan on maxilla were consistent with nasolabial cyst. The histopathologic features, differential diagnosis, treatment and prognosis are discussed.

Osteoma is defined as a benign neoplasm of bony tissue. Osteomas are divided into two groups: central and peripheral by origin, compact and cancellous by histopathologic findings. Solitary osteoma of jaw bone, not related with Gardner syndrom, is relatively uncommon. We present two cases of huge solitary peripheral osteomas: compact type exophyting osteoma on the inferolingual side of mandibular angle and cancellous type on the residual ridge of posterior maxilla, which is extremely rare.

Few cases of florid osseous dysplasia has been described as a condition that characteristically affects the jaws. It usually manifests as multiple radiopaque masses distributed throughout the jaws. Confusion exists about the relationship of florid osseous dysplasia, gigantiform cementoma, chronic sclersing osteomyelitis, sclerosing osteitis or multiple enostosis. Authors experienced a case of florid osseous dysplasia of the jaws in 52-year-old female on the basis of clinical, radiographic and histopathologic findings. The characteristic features are as follows : 1. In clinical examination, there was no clinical sign and symptoms except extracted area. And there was no facial asymmetry. 2. Radiograms show round or lobular dense radiopaque masses surrounded by radiolucent bands in lower molar teeth area bilaterally. And slight increased radiopacities in maxillary molar teeth area bilaterally. There was no expansion or thinning of buccal and lingual cortical bones. There is no displacement or resorption of involved teeth. In right side of mandible, mandibular canal is displaced inferiorly due to mass. 3. Photomicrograms show densely mineralized sclerotic acellular masses with empty lacunae. Pattern is suggestive of cementum, although it could be considered sclerotic bone. In the periphery, lesion consisting of moderately cellular fibrous tissue in which globular calcified products are deposited.

A black kite (Milvus migrans) was referred to the Gyeongnam Wild Animal Rescue Center, Jinju, Korea, with a clinical history of lethargy. On physical examination, three hard, variable sized, round shaped masses were found in the carpal and digit region of the right wing. On plain radiographs, three various sized, round to oval shaped, bony opacity masses with smooth margin were identified on the major digit, alular digit, carpometacarpus. The bird was euthanized due to poor prognosis. A full necropsy was performed, and the histopathologic findings in the bird were consistent with multiple exostoses.

The clinical and pathological analysis of solitary pulmonary nodules were estimated in 35 patients with nodules who were surgically resected at the Dept. of Thoracic and Cardiovascular Surgery of Chonnam National University Hospital from July 1978 to Aug. 1989. The results were as follows: 1. Mean age of patients was 43.5 years extending from 11 years to fi7 years old and male to female ratio was 6: l. 2. Preoperative symptoms were complained of dull pain in the chest, cough, hemoptysis and general weakness in 69% of patients. 3. The histopathologic findings of surgically resected nodules showed benign nodule in 51% and malignancy 49%. The most frequent diseases were granuloma[67%] in benign nodules and squamous cell carcinoma[76%] in malignancy. In topographical region of nodules in the lung, benign granuloma was more prevalent in upper lobes, while malignancy was slightly more frequent in lower lobes. 4. The incidence of malignancy by age was extremely rare in patients with less than 35 years old, but in greater than 35 years of age, malignancy comprised up to 67% of patients. 5. Complications of thoracotomy were minor bleedings, wound infections and chest pain not to be required any reoperation except one patient died of sudden onset of arrhythmia after pneumonectomy.

Nasopalatine duct cysts are the most common non-odontogenic developmental cyst originating in the incisive canal of maxilla and occuring in approximately 1% of the population. Clinical presentation is mostly asymptomatic in small cysts, but sometimes shows swelling, pain and drainage when it is infected. The definite diagnosis should be based on clinical, radiological and histopathologic findings. Marsupialization of the cystic tissue can be performed, however, complete surgical excision is the the choice of treatment of nasopalatine duct cysts. We report a case of nasopalatine duct cyst occurred in the midline of hard palate treated by complete excision via transoral approach.

Low-grade myofibroblastic sarcoma is a rare disorder of malignant soft tissue tumor and is usually occurred various regions that often manifests in the head and neck region. The most common clinical presentation of this entity is non-tender cervical lymphadenopathy. This disease usually presents high possibility of local recurrence and low possibility of distant metastasis. We report a rare case of low-grade myofibroblastic sarcoma occurring in the sternocleidomastoid muscle and invading to the mastoid tip. A 56-year-old male visited the clinic with a complaint of slowly growing postauricular mass for 6 months. Mass originating from sternomastoid muscle and invasion to mastoid tip was observed by imaging studies. Surgical complete excision with simple mastoidectomy was performed via modified facelift approach. The histopathologic findings revealed malignant spindle cell tumor with positive staining with smooth muscle actin. The patient has no recurrence for 2years without any complication.

Bovine abdominal fat necrosis (lipomatosis) is relatively common disorder in adult Korean indigenous cattle. Thirteen Korean indigenous cattle with bovine lipomatosis and five clinically healthy cattle were selected and serum biochemical profiles were analyzed. Serum free fatty acids level was significantly high, while total cholesterol, serum albumin and total calcium levels were significantly low in bovine lipomatosis group. In a case of necropsy, saponificated adipose masses surrounding colon was observed and hepatic fatty degeneration and fat deposition in the renal tubules were found in a histopathologic examination. These findings indicate that affected cattle have a predisposition to deposit more fat into adipose tissue than normal cattle. Such abnormalities might lead to the development of abdominal fat necrosis with fibroplasia and possibly compress the intestines and urinary organs.

A 6-year-old intact male Doberman pinscher presented with a thin soft stool and urinary signs. On radiography, three masses were observed in the caudal abdomen. One mass was described as a large, round, mineralized mass, with an "eggshell" appearance. The second mass was located caudal to the mineralized mass, and the third mass was located between the two masses. The second and the third masses had a soft tissue density. Ultrasonography was performed to identify the features and the origins of the masses. The first mass contained a large amount of anechoic fluid and had a thin wall; it was determined to be a cyst. Strong acoustic shadowing artifact was created by the mineralized cystic wall. Caudal to the cyst, the second mass was shown to be the prostate. A hypoechoic stalk connected the prostate and the cyst, which represented the cyst as a paraprostatic cyst with mineralization. The third mass was the normal urinary bladder. The cyst was removed surgically and confirmed by histopathologic examination. This report described typical clinical findings, diagnostic imaging, and treatment of a paraprostatic cyst.

A one year old spayed female Bichon Frise dog presented with gait abnormalities and seizure. Serum biochemical results showed elevated levels of alkaline phosphatase, alanine aminotransferase, and ammonia. Serum bile acid level was also increased to be over 30 μmol/L on preprandial. Urinalysis identified the presence of ammonium urate crystal. Abdominal ultrasonography and CT revealed aberrant, tortuous, and multiple small vessels connected to the caudal vena cava between left kidney and caudal vena cava. Macroscopic specific findings associated with extrahepatic congenital portosystemic shunts (PSS) or other liver diseases were not identified. Liver biopsy was performed. Histopathologic evaluation revealed hepatic lobular hypoplasia with portal arterial duplication and vascular shunts. Based on these finding, this case was diagnosed as multiple acquired PSS secondary to hepatic microvascular dysplasia (HMD) and hepatic encephalopathy. A liver biopsy is recommended to differentiate HMD from other liver diseases and to confirm HMD when a young dog has multiple acquired PSS.
