Most clinicians have taken a lot of interest in tumors arising from the bony thorax because not only of their rarity and predictable diagnosis which could be reflected as a unique radiologic shadow but also variable surgical modes for maintenance of chest wall stability encountered after en-bloc resection. By the retrospective review, we have analyzed 24 cases of primary bony thorax tumors which were experienced and surgically treated at the St. Mary`s hospital of Catholic Medical College from Jan. 1969 to Sept. 1984. The results are as follows: 1. Age incidence was evenly distributed through all decades and the male-female ratio is 15:9. 2. 16 cases out of 24 were benign tumors and the commonest one of which was fibrous dysplasia. 3. Remaining 8 cases were malignant tumors and among which osteogenic sarcoma was the commonest one. 4. The majority of tumors [22/24] were developed from the rib and the remains were from the sternum. 5. Common manifestation were palpable mass or swelling and localized tenderness. 6. Various kinds of operative procedure were underwent: single resection of rib including tumor,14 cases; multiple resection of ribs with chemotherapy or myoplasty, 2 cases; en-bloc resection of the chest wall and reconstructive procedure, 5 cases; partial resection of sternum, 1 case; bone biopsy and chemotherapy, 2 cases.

The author observed a case of osteogenic sarcoma in a 11-year-old female with complaint of painful swelling on face in right side. The observed results were as follows: 1. Large hematoma was obsered, and patient complanited painfull swelling on c/c site. 2. Predisposing factor of osteogenic sarcoma was not clear, but patient had history of extraction before patient visiting infirmary of our dental collage. 3. Serologic findings were not specific, and serum alkaline level was normal. 4. Radiographic findings were as follows: ① Diffuse faint radiopacity in the lesion ② Bony destruction and increased radiopaciy in right antrum ③ Displacement of multiple teeth on involved area(i. e ;＃12, 15. 55, 16, 17, 18), ④, Increased periodontal space in singel tooth(＃13) ⑤Destruction of bony crypt on involved teeth(＃13, 14, 15, 17, 18) ⑥ Loss of lamina dura of three teeth in involved area(＃11, 12, 16) 5. Computed tomographic findings were as follows: ① Large calcific and hetergenous component mass in the Rt. maxillary sinus, and this mass extending to Rt. maxilla, alveolar bone, ethmoid sinus. ②, Soft tissue bulging into Rt. side nasal cavity and oral cavity. ③ Bone destruction of maxillary sinus wall and Rt. alveolar bone.

The authors report a case of Currarino triad which had a congenital anorectal stenosis associated with a sacral defect and a presacral mass. A 1-year-old female presented with constipation since birth. Neurological deficits were not found on admission. She had had a diverting colostomy due to anorectal stenosis at another hospital before admission. Lumbar X-ray films showed bony defect caudal to the third sacral vertebra. Magnetic resonance image demonstrated a round cystic pelvic mass which was connected with a dural sac via anterior sacral defect. Posterior approach with Intradural removal of the presacral cystic mass was performed and followed by anoplasty by a pediatric surgeon. The cystic mass was verified histologically as mature teratoma with cystic change. Postoperatively, the urinary function and bowel movement remained intact. Currarino triad should be suspected and evaluated physically and radiographically in a case of congenital anorectal stenosis. Prompt recognition and close cooperation between pediatric surgeons and neurosurgeons is advisable to ensure adequate surgical treatment.

We report here two cases of primary intraosseous meningioma with aggressive behavior. A 68-year-old man presented with a one year history of a soft, enlarging mass in the right parietal region. Magnetic resonance image (MRI) revealed a 6 cm sized, heterogeneously-enhancing, bony expansi1e mass in the right parietal bone, and computed tomograph (CT) showed a bony, destructive lesion. The tumor, including the surrounding normal bone, was totally resected. Dural invasion was not apparent Diagnosis was atypical meningioma, which extensively metastasized within the skull one year later. A 74-year-old woman presented with a 5-month history of a soft mass on the left frontal area. MRI revealed a 4 cm sized, multilobulated, strongly-enhancing lesion on the left frontal bone, and CT showed a destructive lesion. The mass was adhered tightly to the scalp and dura mater. The lesion was totally removed. Biopsy showed a papillary meningioma. The patient refused adjuvant radiation therapy and later underwent two reoperations for recurred lesions, at 19 and at 45 months postoperative. The patient experienced back pain 5 years later, and MRI showed an osteolytic lesion on the 11th thoracic vertebra. After her operation, a metastatic papillary meningioma was diagnosed. These osteolytic intraosseous meningiomas had atypical/malignant pathologies, which metastasized to whole skull and the spine.

We experienced a case of soft tissue osteochondroma in the foot. The 43-years-old male was complained palpable mass and mild pain at the heel for 3 years. The plain radiograpy revealed a bony mass without connection of neighbor bone in the heel. The osteochondroma in the soft tissue is rare benign tumor. The mass was removed en bloc. The gross and histologic findings were consistent with osteochondroma. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, soft tissue osteochondroma, and true osteochondroma which arises from bone. The symptom was improved. After postoperative 1 year, recurrence was not.

A 65-year-old woman presented with a solid mass on the right temporal area. The mass had grown for over 2 years without any initiating event of trauma or inflammation. Before excision, the patient went through a computed tomography scan, revealing a calcified mass without bony connection. Under general anesthesia, an excisional biopsy was performed. Microscopic examination confirmed a diagnosis of soft tissue osteoma. Soft tissue osteoma is rare, especially in the head and neck region. Osteomas in the temporal region have not been reported yet. Due to its rarity, osteoma might be misdiagnosed as another soft tissue or bone origin tumor. Its treatment of choice is simple excision. In this review, we present an unusual clinical form of soft tissue osteoma.

A 10-year-old castrated male Shih Tzu dog was submitted to a local animal hospital with a mass from gingiva to maxillofacial skeleton. Computed tomography revealed that strong invasion of the mass result in osteolysis in orbit and frontal bone. The excised mass was presented to the Pathology Department of the Veterinary Medicine, Jeju National University. Surgically excised mass was rubbery to firm in consistency. Histologically, the neoplastic mass was composed of irregular or interdigitating cords, islands or pseudo-glandular structures of stratified epithelial cells. These cords or islands showed typical palisading pattern of neoplastic epithelial cells to periphery without intercellular bridge (desmosome) and surrounded by eosinophilic immature collagenous matrix. Some area showed islands of well differentiated keratinizing squamous cell foci. Some lumen of glandular structures contained fibrin-like materials and RBC. These neoplastic cells showed marked invasive tendency to adjacent connective tissues and bony tissues, therefore solitary neoplastic cells were widely distributed throughout the surround connective tissue. The neoplastic cells showed positive reactions for pan-CK and CK14, weakly positive reaction for CK5/6. And the surrounding immature collagenous matrix was only labeled for vimentin.

Patient with complaints of swelling, pain in the maxillaly region and discomfort visited Seoul National University Dental Hospital in August last year. Clinical examination and diagnostic imagings implied he was suffered from fungal hyphal infection but no causative fungus was found by the histopathologic and microbiologic investigation. Therefore he was diagnosed with nonspecific inflammation. But as yet, we do think this case is very similar to some kinds of mucormycosis. So we presented this case for more thorough discussion.Followings are founded in the examination. 1. Patient had suffered from Diabetes mellitus and complained of stuffness, headache, swelling in buccal cheeks and paresthesia And we found more maxillary bony destruction and ulcer with elevated margin in the palate by clinical examination. 2. In the first visit, Plain films revealed general bony destruction of the maxilla, radiopaqueness in the sinonasal cavities. or and MRI showed soft tissue mass filled in the paranasal sinus except frontal sinus and bony destruction in involved bones. 3. No causative bacteria and fungus was found in the biopsy and microbiologic cultures. 4. Caldwell-Luc operation and curettage were carried and antJbiotics were taken for 4 months. But now he was worse than in the past 5. In the second visit, involvement of orbit, parapharyngeal sinus, clivus, cavernous sinus and middle cranial fossa were seen clearly in the or and MRI.

Beta tricalcium phosphate (${\beta}-TCP$) is one of allogenic bone substitute which is known to have interconnected pores that draws cell and nutrients for bone generation. It has been resulted in good outcomes for bone defect coverage or augmentation. However, several studies have also reported negative outcomes and associated complications including unexpected formation of cystic mass, continuous pain and secretion. We present the case of a 36-year-old man with a right cheek cystic mass who had a history of right zygomaticomaxillary (ZM) complex fracture and surgical correction with ${\beta}-TCP$ powder insertion to ZM bone defect. Excisional biopsy under local anesthesia revealed calcified mass in a sinus tract which was found to be connected to the ZM bone defect site in postoperative computed tomography image. Further excision under general anesthesia was performed to remove the sinus tract and fine granules which filled the original defect site. Pathologic report revealed bony spicules and calcification materials with chronic foreign body reaction. Postoperative complications and recurrence were not reported.

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.
