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.

The soft tissue tumors that occur commonly in newborn infants include palatal and gingival cyst of the newborn, congenital epulis, hemangioma, teratoma, pyogenic granuloma, and irritation fibroma. Such soft tissue tumors in the alveolar ridge of newborns are usually treated by surgical excision. If untreated, they can cause airway obstruction and breathing difficulty due to aspiration. They also cause discomfort during oral feeding. If nasal feeding is tried, since vomitting is impossible, there is a risk of aspiration pneumonia. In this case, a newborn infant visited our hospital with soft tissue tumor as chief complaint, and the infant was treated by surgical excision. It appeared to be similar to pyogenic granuloma and irritation fibroma upon histologic exam. However, it was different from those diseases since multinucleated giant cells were observed and it was congenital. The pathologic process of this neoplasm is not clear. This case is reported, since it is difficult to classify it as a specific disease.

Fibroma of tendon sheath is an uncommon benign soft tissue tumor with a predilection for the hand or upper extremities with extremely rare intra-articular involvement. It is mostly comprised of slow-growing fibrous lobules made up of scattered fibroblasts in a dense stroma with slit-like vascular channels. An unique case in a 54-year-old male patient involving the glenohumeral joint arising from postersuperior joint capsule is reported. Magnetic Resonance Imaging (MRI) reveals a focal nodular mass with decreased signal intensity on all pulse sequences and pathology confirmation was made with arthroscopic excision. Intra-articular fibroma of tendon sheath should be considered in the differential diagnosis of intra-articular soft tissue masses during shoulder arthroscopy.

Juvenile ossifying fibroma (JOF) is a variant of the ossifying fibroma and includes two histopathological subtypes: trabecular and psammomatoid. Psammomatoid JOF (PJOF) in craniofacial structures should be distinguished from other fibro-osseous lesions, such as fibrous dysplasia (FD), considering the difference in the treatment protocols. Here, we present a rare case of PJOF that was initially misdiagnosed as a case of FD and emphasize the importance of considering JOF in the differential diagnosis of patients with craniofacial fibro-osseous lesions. A 4-year-old boy demonstrated progressive enlargement of the zygomaticomaxillary area on his left side for the last 6 months. The patient was diagnosed as a case of FD based on the clinical features and radiographic findings, and was operated considering the rapid progression. To achieve facial symmetry, contouring of the zygomatic bone and arch was performed. However, the patient demonstrated rapid enlargement at the 3-month postoperative follow-up. The decision was made to surgically remove the tumor due to visual field impairment. Intraoperatively, a rubbery mass, which was separated from the surrounding cortical bone, was identified and excised. The lesion was confirmed as PJOF by histopathological examination. The possibility of PJOF should not be ruled out in the differential diagnosis of patients with fibrous-osseous lesions. In the event of suspected PJOF, accurate diagnosis should be made through definitive biopsy.

Fibroma of the tendon sheath is a benign slow-growing fibrous tumor. Although rare, cases occurring in the upper extremities usually involve the fingers. It appears as a well-defined, roundor oval-shaped mass originating from the flexor tendon. Abundant fibrous stroma makes fibromas appear as a low intensity mass in all MRI sequences. Most of the fibromas manifest as painless soft tissue masses. Herein, we report a case of fibroma of the tendon sheath with an unusual clinical presentation, triggering carpal tunnel syndrome during wrist movement.

This is a case of cemento-ossifying fibroma in mandible, one of fibro-osseous lesions arising in periodontal ligament, with review of literature for fibro-osseous lesions. En-bloc resection of mandible with alloplastic material ($Pyrost^{\circledR}$) was performed in cemento-ossifying fibroma of 20-year young male patient. By follow-up check of the patient, we obtained good result without any signs of recurrence.

Meigs' syndome consists of an ovarian fibroma, or fibroma-like benign tumor, associated with fluid in both abdomen and chest. Characteristically, the ascites and hydrothorax disappeared and do not recurred following removal of the ovarian tumor. The authors presented a case of Meigs' syndrome that was cured by surgical removal of ovarian tumor and resulted in normal pregnancy outcome in 27-year-old pregnant woman with a brief review of literatures.

Calcifying aponeurotic fibroma (CAF) is an uncommon benign tumor and a locally aggressive fibroblastic lesion. It commonly affects the palmar side of the hand and fingers, and the soles of the feet. The typical clinical manifestations are known as a poorly circumscribed, slow-growing, and asymptomatic firm mass. Most CAFs usually reveal low to intermediate or isointensity on T1-weighted images, and strong heterogeneous enhancement. However, various signal intensities on T2-weighted images have been reported depending on the degree of hypocellularity or the amount of calcification or collagen within the tumor. This report provides the radiographic and MRI finding of CAF arising in uncommon site, the knee region, of a 19-year-old male who presented with a painful and palpable mass.

In certain low-grade malignant bone tumors such as chondrosarcoma or frequent recurrent benign bone tumors as ossifying fibroma, radical treatment may provide a good chance for cure. And large bony defect after the radical treatment can be filled with the massive bone graft. Recent advances in clinical microsurgery have made free vascularized bone graft a clinical reality, and Taylor in 1975, first reported the technique of free vascularized fibula graft for the reconstruction of large tibial defect with excellent clinical results. We tried wide excision and free vascularized fibula graft in 5 patients with ossifying fibroma and one patient with chondrosarcoma from January 1984 to December 1994 and followed for more one year. The shortest bony defect was 7cm and the longest bony defect was 20cm and mean bony defect was 13cm. All patients were evaluated clinically and roentgenographycally on basis of functional recovery and bony union. All patients showed satisfactory functional recovery with sound bony union and showed bony hypertrophy. And, local recurrence was not seen.

Since the fibro-osseous lesion is not a specific diagnostic term, the author studied clinically and radiologically 44 cases which had been diagnosed as fibro-osseous lesion in SNUDH (1972- 1981. 12).The obtained results were as follows. 1. Clinico-radiologically, the cases of fibro-osseous lesions were divided into two groups. 2. The first group was fibrous dysplasia (21 cases). 3. The second group was tumors of periodontal ligament origin, including ossifying fibroma, cementifying fibroma and cemento-ossifying fibroma (23 cases). 4. In most cases the chief complaint was painless swelling of the jaw and the mean age of the fibrous dysplasia (24.6 yrs) was a little younger than that of the periodontal ligament origin lesions (29.2 yrs). 5. In fibrous dysplasia, maxilla was more often involved and showed ground-glass or smoke pattern radiologically. 6. The tumors of periodontal ligament origin occurred more in female, mandible and radiologically showed varying amounts of radiopaque foci in well-circumscribed osteolytic lesion.
