Desmoplastic fibroma is a rare primary tumor of bone that histologically and biologically mimics the extra-abdominal desmoid tumor of soft tissue. This report is dealt with two cases of desmoplastic fibroma occurring in a 22-year-old male, scapular lesion and 34-year-old male, pubic lesion. Radiologically, the tumors were lucent and expansile lesions. Histologically, they contained slender spindle cells and various amounts of collagen fibers. Radical excision was done on both cases and no recurrence was reported. Because of its rarity, we report two cases of desmoplastic fibroma.

Cardiac papillary fibroelastomas are the second most common primary cardiac tumor. This tumor is usually benign and it involves the cardiac valve. However, most cardiac papillary fibroelastomas originate from a single site, and the incidence of cardiac papillary fibroelastomas originating from multiple sites is very rare (5%). A 55-year-old woman who presented with momentary dizziness and syncope was evaluated by performing echocardiography. Multiple tumors attached to the aortic valve were noted. The mass was removed freely without leaving any defect on the aortic valve leaflet. After the recovery period, the patient is currently being followed up at the outpatient department.

Desmoplastic fibroma of bone is an extremely rare tumor that was first described by Jaffe in 1958. It histologically resembles the desmoid tumor of soft tissue. It is known as locally aggressive tumor but we experienced definitely benign and resembling simple bone cyst radiographically. We report a case of desmoplastic fibroma of bone and it should be included in the differential diagnosis list of any lytic bone lesion. The radiograph, MR imaging features, radiological and pathological differential diagnosis of the case are described, and literatures are reviewed.

The following tumors occurring naturally in the dog were studied pathologically and discussed briefly. Tumors of the skin and subcutis: Fibroma, Lipoma, Epidermal cyst, Melanosarcoma, Sweat gland adenoma, Mastocytoma (2 cases), Mastosarcoma, and Sebaceous gland carcinoma. Tumors of the spleen and lymph node: Fibrosarcoma of the capsule of spleen, Leiomysarcoma of the spleen, and Lymphosarcoma of the lymph node (2 cases). Tumors of the lung: Bronchogenic carcinoma (3 cases), Adenocarcinoma type, Squamous carcinoma type, and Undifferentiated (round cell) carcinoma type respectively. Tumors of the alimentary tract and liver: Fibroma of the stomach, Hemangioma of the liver, Bile duct carcinoma, Liver cell carcinoma, and Myelogenous leukemia manifested in the liver. Tumor of the peritoneum: Fibrosarcoma. Tumors of the urogenital system: Fibroma of the uterus, Fibroma of the prepuce, Follicular cyst of the ovary, Transmissible venereal tumor of the vagina (6 cases), Carcinoma of the kidney, Adenoma of the prostate (2 cases), and Seminoma of the testis. Tumors of the mammary gland: Mixed tumor (2 cases), and Myoepithelioma. Tumor of the nervous system: Neurofibrosarcoma of the thigh.

Low grade fibromyxoid sarcoma is a recently recognized, uncommon soft tissue neoplasm. It has a tendency to develop in deep soft tissue of young adults and a possibility of local recurrence or distant metastasis. Diagnostic criteria have not been well defined and this tumor has not been accepted as a distinct entity. Histologically, it is characterized by the presence of bland spindle cells with mainly whorled pattern of growth, set in alternating areas with a myxoid or fibrous stroma. Careful consideration of the morphological and immunohistochemical features of this tumor permit a positive diagnosis of low grade fibromyxoid sarcoma and allow its distinction from a number of other benign and malignant soft tissue neoplasms. We experienced a low grade fibromyxoid sarcoma in chest wall and report this case with a review of the literature.

Purpose: We evaluate the results of treatment of pathologic femur fractures secondary to bone tumors in children. Materials and Methods: Between January 1995 and June 2004, 18 patients(20 cases) were evaluated. Their mean age of the first episode of fracture was 10.2 years and mean follow-up period is 42.5 months. Primary bone tumors, the location of fracture, time to union and complications were evauated. Results: Fractures occurred at proximal portion in 14 cases, shaft 3 cases and distal portion 3 cases. The bone tumors causing pathologic fracture were fibrous dysplasia(9 c ases), simple bone cyst(4 cases), aneurysmal bone cyst(4 cases), nonossifying fibroma(2 cases) and eosinophilic granuloma(1 case). In the treatment for fractures, cast was in 11 cases, internal fixation 8 cases and external fixation in 1 case. In the treatment for tumors, observation was in 11 cases, curettage & bone graft in 8 cases and resection in 1 case. In polyostotic fibrous dysplasia, all cases were treated by cast initially but deformity developed in all cases. Fracture prevention and deformity correction were obtained with intramedullary nailing. Conclusion: Adequate choice of treatment of bone tumor and fracture will result in good prognosis.

Solitary fibrous tumors of the pleura (SFTPs) are relatively rare tumors that originate from the mesenchymal cells of the submesothelial tissue of the pleura. Patients with SFTPs are often asymptomatic, while some patients experience pleuritic chest pain, cough and/or dyspnea. We report here on a case of SFTP, and the patient presented with septic shock and respiratory failure that required mechanical ventilation. A 68-year-old woman was admitted for the evaluation of her dyspnea and generalized edema. Chest imaging studies showed an 18 cm-sized voluminous mass occupying the right thoracic cavity with anterior displacement of hilar structures and atelectasis of the right lung. Immediately after admission, she developed pneumonia and septic shock that required antibiotics and mechanical ventilation. She displayed a partial response to medical treatment, and then complete excision of the tumor was performed and the pathologic examination revealed benign SFTP. Afterward, she fully improved without evidence of recurrence until now.

Chondromyxoid fibroma occurring in the hand is a rare benign tumor. Radiologically and histologically, it should be differentiated from the other benign bone lesions in the hand, such as enchondroma, chondroblastoma, giant cell reparative granuloma and chondrosarcoma. This report is dealt with 59-year-old female and 19-year-old male patient presenting lesions on their digits anddescribed unusual clinical, radiological and pathological features.

Fibrous dysplasia is a condition characterized by the replacement of the medullary component of predominantly long bone with fibrous tissues. The monostotic form of the fibrous dysplasia occurs more frequent than the polyostotic form. Only the twenty three previous cases of vertebral involvement in monostotic fibrous dysplasia have been reported. Authors experienced a case of monostotic fibrous dysplasia of the third lumbar vertebra, so we report this case. Report details the diagnosis and treatment of a 34 years old man with back pain from monostotic fibrous dysplasia of the third lumbar vertebra. We discuss the experience in the consideration of previous report to recommend the optimal management of this disease.

This case describes a case of desmoplastic fibroma of the mandible. A 9-year-old boy was seen with a history of progressive swelling and expansion of the left mandible for one month period. Desmoplastic fibroma was diagnosed on histopathologic examination This report reviews the diagnostic criteria, differential diagnosis and surgical treatment of choice in brief of this uncommon primary bone tumor of the oral and maxillofacial region.
