Brown tumor is usually diagnosed at the terminal stage of hyperparathyroidism. Diagnosis of this tumor is confirmed by endocrinologic investigations along with clinical and radiographic examination. Radiographical differential diagnosis of this tumor includes central giant cell granuloma, aneurysmal bone cyst, metastatic tumor, multiple myeloma, and Paget disease. This report presents a rare case of multiple brown tumors occurring at the maxilla and mandible, which was initially misdiagnosed as central giant cell granuloma. Plain radiographs demonstrated multiple well-defined multilocular radiolucency. CT images showed soft tissue mass with low attenuated lesions, perforation of the lingual cortical plate, and a heterogeneous mass at the right thyroid lobe. These findings were consistent with parathyroid adenoma. The patient had hypercalcemia, hypophosphatemia, and elevated alkaline phosphatase level. Surgical excision of the tumor was performed. No recurrence was observed during a 28-month follow-up.

The objectives of this study were; (1) to identify and localize QTLs for resistance to soybean cyst nematode(SCN) race 5 on RAPD map, (2) to idntify the magnitude and mode of inheritance for each QTL, and (3) to identify the best combinations of QTLs for resistance to SCN race 5. Based on the univariate regression analysis, we detected 26 markers(22 RAPD and 4 RFLP) which showed significant association(P<0.05) with resistance to SCN race 5. From MAPMAKER /QTL analysis, we identified two regions (LGC-20 and Group 2) for resistance to SCN race 5. The QTL that was localized at 8.0 cM from pK418C on LGC-20 showed a recessive mode of inheritance and the QTL that was localized between W03 and E02$^3$ on Group 2 showed a dominant mode of inheritance. Two pairs of flanking markers (E02$^3$ and W03, pK418C and pK418E$_1$) and one unlinked RAPD marker, G10$^1$ were used for multiple regression analysis. Marker combination which was composed of 4 markers, E02$^3$, G10$^1$, W03, and pK418E$_1$, explained the highest amount of phenotypic variation by SCN (35.2％). Further research for the identification of QTLs for resistance to SCN race 5 to explain larger portion of phenotypic variation is needed.

A 3-month-old female mixed breed cat was referred to the veterinary medical teaching hospital of Seoul National University with ocular discharge and blepharospasm of both eyes. On ophthalmic examination, the patient was diagnosed as multiple ocular defects : eyelid coloboma, keratoconjunctivitis sicca, persistent pupillary membrane, uveal cyst, incipient cataract and choroidal hypoplasia. On histopathologic examination, choroidal hypoplasia was confirmed.

Aneurysmal bone cyst(ABC) is a benign lesion and generally occurs in the long bones and vertebral column. ABC of the rib is an uncommon entity. We reported a case of ABC originating in the left first rib. The patient was a 19-year-old woman and presented with palpable mass on the shoulder. Chest X ray and MRI showed a large expansile mass, with multiple cystic areas, arising from the left first rib and bulging out into retroclavicular and paravertebral soft tissue, so the lesion was initially misdiagnosed as a soft tissue malignant tumor destructing adjacent rib. On histological examination, the mass, which was surrounded by a peripheral band of mature trabecular bone, consisted of multiple anastomosing cavernous blood channels separated by fibrous septa that containing osteoid, myxochondroid material and osteoclast-type giant cells.

Pulmonary histiocytosis X is an idiopathic benign disease characterized by proliferation and infiltration of lung tissue by characteristic Langerhans cells and eosinophils. Pulmonary histiocytosis X is common in young male adults, and shows variable clinical characteristics. We experienced a case of pathologically proven pulmonary histiocytosis X in a 30-year-old man who visit to our hospital due to chest discomfort and cough. The chest radiograph of our patient shows right pneumothorax and characteristic multiple thin-walled cysts on the both upper lung fields. The HRCT shows multiple thin-walled cysts, a few scattered nodules in both upper and right middle lung, and right pneumothorax.

Hemangioblastomas are rare benign tumor of the central nervous system that commonly occur in the posterior fossa around the 4th ventricle. In case of von Hippel-Lindau disease, hemangioblastomas involve multiple regions such as cerebellum, spinal cord and brainstem but, rarely show simultaneous involvement of cerebellum and spinal cord. We have experienced a case of multiple hemangioblastomas that were located at the cerebellum, cervical cord and conus medullaris and also had multiple lesions that a part of von Hippel-Lindau disease ; retinal angioma, syringomyelia, multiple cyst on kidney and pancreas, renal cell carcinoma on left kidney. Hemangioblastomas on cerebellum and spinal cord were removed totally, retinal angioma was treated with laser photocoagulation and renal cell carcinoma was also totally excised. The authors report a case of von Hippel-Lindau disease had multiple located hemangioblastomas on cerebellum, cervical cord and conus medullaris with review of literature.

To evaluate the functional status of ovarian cyst in Korean native cows, progesterone ($P_4$) and estrogen ($E_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian cysts were classified as single follicular cyst 51 cows (59.3%), multiple follicular cysts 19 cows (22.1%), single luteal cyst 13 cows (15.1%) and multiple luteal cysts 3 cows (3.5 %) by anatomical and ultrasonography. Ovarian cysts were classified as follicular cysts (54 cows), luteal cyst (16 cows) and non-functional ovarian cyst (16 cows) by hormone analysis, anatomical finding and ultasonography The luteal cyst was accurately diagnosed by cystic wall thickness, but follicular cysts was misdiagnosed 16 cows of 70 cystic cows The cystic fluid $P_4$ concentration was 3.3 ng/ml in follicular cysts and 30.1 ng/ml luteal cysts. There was significantly positive correlations between cystic wall thickness and serum $P_4$ concentration in follicular ($r^2=0.59$, p<0.001) and luteal cysts ($r^2=0.65$, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accurately diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts were not diagnosed only cystic diameter and cystic wall thickness.

The congenital cystic adenomatoid malformation of the lung is a rare disease, and is one of the most common congenital lung diseases which require prompt surgical intervention. The prognosis depends on its tissue type, prompt diagnosis and surgical intervention. The lesion consists of enlarged, variable sized multiple cyst with overgrowth of terminal bronchioles, like hamartoma. This disease can be associated with other vascular anomalies or other congenital defect especially in type II lesion We recently experienced one case of congenital cystic adenomatoid malformation The patient was 2 months old infant who showed respiratory distress without associated anomaly. After right upper lobe lobectomy, the patient was recovered uneventfully.

Purpose: Steatocystoma multiplex is a rare benign disease that occurred multiply on whole body surface. Many physicians have tried managing steatocystoma in variable methods. However it is hard to define the optimal way to cure steatocystoma. We performed both aspiration and excisional method to study the usefulness of both methods. Methods: A 28-year-old woman has asymptomatic multiple subcutaneous nodules on whole body. Most lesions were aspirated with 26-guage needled 3 cc syringe but large and purulent three nodules were excised. Results: We diagnosed the lesion histologically as steatocystoma multiplex. Aspirated wound healed without scar, excised wound remained scar but esthetically acceptable. Axillary lesion contained so clustered type cysts that was difficult to aspirate whole cyst. Thus additional excisional method was needed. Conclusion: There are many practical methods to cure steatocystoma. However, there is no appropriate method to cure it. Therefore we should select different therapeutic method according to anatomical location and cyst size. Especially at subcutaneous fat-rich lesion like axilla and abdomen, it is better to excise the clustered cyst than to aspirate.
