Abstract
The aim of this systematic review was to address the clinicopathologic inconsistencies noted with primary oral leiomyosarcoma in the literature by amassing the available data published into a comprehensive analysis. Eligibility criteria included publications of cases with dedicated immunohistochemical work-up along with radiographs to evaluate location. Based on these criteria, the systematic review compiled 29 cases. Four primary location sites were identified in the reported cases: soft tissue presentation only, soft tissue with bony involvement, bony involvement only, and bony involvement with a soft tissue component. The majority of primary oral leiomyosarcoma cases reviewed showed a soft tissue predilection, which is in contrast to prior reports of jawbones being the most common site. In addition, there was an improved 5-year survival rate for primary oral leiomyosarcoma limited to the oral cavity and gnathic bones without extension into paranasal sinuses.

Abstract
PURPOSE As a review and clinical analysis of primary oral leiomyosarcoma (LMS) cases in West China stomatology Hospital in the past 37 years, this study provides demographic, therapeutic and prognostic information of this rare tumor. PATIENTS AND METHODS In our study, 20 cases of primary oral LMS treated between 1972 and 2008 in West China Stomatology Hospital were analyzed retrospectively. A thorough review of clinical records was carried out and potential indicators of survival were analyzed. RESULTS The most common symptom of oral LMS presented as a painless mass. The median age of patients was 37 years, and the peak incidence age of this tumor was in the 2nd and 5th decades. There was no predilection of gender, and the male-to-female ratio was 11:9. The most frequently occurring site of oral leiomysarcoma was the jawbones. The prognosis of this tumor was poor as a result of the high local recurrence and the estimated 2 year survival was 17.6%. The bony involvement and method of therapy was observed to have an influence on the prognosis and survival of this tumor (P < 0.05). CONCLUSION There was a predilection site of jawbones for oral LMS, and bony involvement was a potential indicator suggesting a poorer prognosis. The recommended method of therapy on this tumor was aggressive, radical surgical resection; however, adjuvant radiotherapy and chemotherapy may also have a beneficial effect.

Primary oral leiomyosarcoma: a clinico-pathologic study and analysis of prognostic factors. Int J Oral Maxillofac Surg 2007; 36:409-16. [PMID: 17395428 DOI: 10.1016/j.ijom.2006.12.015] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2006] [Revised: 11/04/2006] [Accepted: 12/27/2006] [Indexed: 11/21/2022]
Abstract
This clinico-pathologic study of primary oral leiomyosarcomas and analysis of potential prognostic factors involved a literature review of 64 cases and a report of four cases treated in the authors' unit. The demographic details, clinical presentation, diagnosis, treatment and outcome were documented for the whole group and clinico-pathologic variables analysed to detect potential prognostic factors. The most common presentation was that of a painless mass, with peak incidence in the 6th decade and a slight male predeliction (M:F=1.3:1). The maxilla was the most frequently involved site, followed by the mandible and tongue. Surgical excision was most commonly employed with radiotherapy and chemotherapy being reserved for recurrent and metastatic tumours. Local recurrence (34%) and metastasis (35%) were not uncommon and occurred most frequently to the lungs and regional lymph nodes (15%). Age, sex, size and mitotic index were not statistically related to recurrence or metastasis. Site (P=0.0125) was a predictor of metastasis. Metastasis (P=0.010) and lesions involving the maxilla and mandible (P=0.019) were associated with decreased survival. The estimated 5 year survival was 55% for the whole group and 43% and 19% for patients with bony involvement and metastasis respectively.

Abstract
PURPOSE Primary oral leiomyosarcomas are rare tumors. Information regarding the biological behavior, prognosis, and appropriate management of this neoplasm is lacking in the literature. The purpose of this report was to summarize the data of isolated case reports of primary oral leiomyosarcoma that have been published in the English literature during the past 25 years. The cases of 4 additional new patients who have been treated in our department during the past 10 years are also presented. PATIENTS AND METHODS The data for 46 patients obtained from 32 individual articles retrieved from the English literature were added to our 4 cases and produced a total number of 50 cases of primary leiomyosarcomas of the oral tissues. Patients were analyzed according to demographic data, anatomic location, type of treatment, and survival. RESULTS Primary oral leiomyosarcoma may affect any age with peaks of occurrence in the third, sixth, and seventh decades of life. There is no gender predilection. Female patients presented the higher incidence in the third decade, whereas males had an even age distribution. The tumor arises in approximately 70% of the cases in the maxillary and mandibular bones. Radical surgery was the treatment of choice. Radiotherapy and chemotherapy when applied in recurrent tumors had little effect. The most adverse prognostic factor was the positive surgical margins. The 5-year survival was 62% (62.9% for females and 52.6% for males, P > .1968). CONCLUSIONS Cases of oral leiomyosarcoma appear to be associated with major neurovascular structures of the facial skeleton, as evidenced from the imaging studies of our 4 patients. Primary oral leiomyosarcoma is a rare tumor that should be managed with aggressive surgical resection in order to safeguard curability. Histopathologic diagnosis is greatly facilitated with positive immunohistochemical staining for smooth muscle antigenic markers.

Abstract
A 2-year-old male Thoroughbred was evaluated for multiple firm, raised nodules of the maxilla and mandible that had been present since 6 months of age. The horse was evaluated as a yearling with a final histologic diagnosis of fibrosarcoma. As a 2-year-old, the colt made a loud upper airway sound and was agitated after strenuous exercise. Results of upper airway endoscopy indicated severe narrowing of the nasal passages and pharynx with normal resting function. Radiography revealed multiple circular bony lesions in the mandible, maxilla, multiple long bones, and cervical vertebrae. Biopsy specimens of the left mandible and right facial bone were obtained. A diagnosis of leiomyosarcoma with extensive metastatic bone formation was made on the basis of histologic features and the immunohistochemical staining properties of the biopsy specimens. Because of the diffuse distribution of the lesions, prognosis was guarded; 4 years after diagnosis, the horse had not pursued an athletic career.

Abstract
AIMS Oral leiomyosarcoma is rare and poorly documented. We aimed to characterize these lesions clinicopathologically in order to facilitate their distinction from other spindle cell neoplasms in the oral cavity. METHODS AND RESULTS Ten cases of oral leiomyosarcoma were retrieved and studied histologically and immunohistochemically. Clinical data were obtained from referring pathologists and prior literature concerning 46 comparable cases was reviewed. Nine out of 10 cases occurred in adults; 50% arose in the jaws and four showed bone involvement. Histological appearances were similar to leiomyosarcomas elsewhere. In addition to myogenic markers, two cases were also keratin-positive. Four patients developed local recurrence or metastatic disease and three died of tumour (median follow-up 37 months). CONCLUSIONS Leiomyosarcoma is under-recognized in the mouth, often being mistaken for a spindle-celled epithelial neoplasm. Aside from an unusual but infrequent tendency to spread to lymph nodes and a location-specific differential diagnosis, its clinicopathological features are comparable to leiomyosarcomas at other locations.

Abstract
Leiomyosarcoma is a malignant neoplasm of smooth muscle origin that manifests itself uncommonly in the oral cavity because of the paucity of smooth muscle in that location. To the best of our knowledge, only 10 cases of leiomyosarcoma primary to the jawbones have been reported in the English language literature. We report the first pediatric case of leiomyosarcoma arising from the mandible. Facial asymmetry and swelling were accompanied by a rapidly growing exophytic soft tissue mass that caused buccal displacement of the mandibular left permanent first molar. The lesion, observed radiographically as an extensive ill-defined area of osteolytic alveolar destruction, perforated the lingual cortex, displaced the inferior alveolar nerve canal inferiorly, and produced a "floating-in-air" appearance of the first molar. Diagnosis of leiomyosarcoma was made after initial incisional biopsy of the lesion. A 5-cm segmental mandibulectomy and supraomohyoid neck dissection were followed by reconstruction with a dynamic mandibular reconstruction plate and placement of a multidimensional mandibular distraction device in a transport rectangle of bone to promote bifocal distraction osteogenesis. Forty millimeters of distraction (the technical limit of the device) were performed; this was followed by terminal iliac crest bone grafting. Seventeen months after the definitive surgical procedure, the patient remains free of disease.

Abstract
Leiomyosarcoma of bone is a rare tumor in an unusual location. Previous analysis of this entity mostly involved small numbers of cases with limited follow-up. Thirty-three patients with leiomyosarcoma of bone between 1977 and 1996 were studied, and the histologic appearance and grade were correlated with subsequent treatment and clinical behavior. To be included in this study the tumor had to be intraosseous, with other primary sites of origin clinically excluded. Also, most of the sarcomatous tissue (> or =70%) had to be of intramedullary location with only limited extraosseous extension. The patient's age at diagnosis ranged from 13 to 77 years (average 44.4). The gender distribution was equal. The long bones were preferentially affected (64%), with the lower extremity, around the knee joint, predominantly involved. Five patients (15%) developed postradiation leiomyosarcomas. The histologic analysis showed that the osseous leiomyosarcomas are most commonly of the classic type, followed by the epithelioid, myxoid, and pleomorphic variants. Immunoreactivity for smooth muscle markers (smooth muscle actin, common muscle actin, desmin) was positive in all tumors, and ultrastructural confirmation was obtained in 21% of cases. All sarcomas were histologically graded, which accurately reflected the subsequent prognosis. Seventy-five percent of the lesions were high-grade and the rest low-grade. The histologic grade of the tumors correlated with both the recurrence as well as the metastatic rates and together with the clinicopathologic stage of disease represented the cornerstone on which prudent therapy should be based.

Abstract
A rare case of oral leiomyosarcoma diagnosed with the aid of immunohistochemical and electron microscopic examinations together with a review of the literature are reported. The patient was a 70-year-old Japanese man. The primary tumor involved the maxillary gingiva and bone and metastasized to the cervical lymph nodes. On histologic examination the tumor showed invasive growth into the maxillary bone. It was composed of interlacing fascicles of spindle-shaped cells with eosinophilic cytoplasm and elongated, blunt-ended nuclei. The tumor formed extensive metastatic foci in the cervical lymph nodes. On immunohistochemical examination most of the tumor cells were positive for desmin, smooth muscle-specific actin, and myosin. The ultrastructural characteristics of the tumor cells were abundant microfilaments, pinocytotic vesicles, and basement membrane formation. The findings were indicative of a tumor demonstrating myogenic differentiation. A review of the literature during the past 50 years disclosed a total of 60 oral leiomyosarcomas, including our case.

Abstract
Leiomyosarcomas (LMS) make up 7% of all soft tissue sarcomas. In the oral cavity, the LMS is rare due to the paucity of smooth muscle in that region. Four cases of intraoral LMS are reported, plus 34 cases found in the literature reviewed. There were 24 males and 14 females. The age range at presentation was 10 months to 88 years with no predilection for any particular age group. The commonest presenting symptom was a mass. The intraoral LMS occurred most commonly in the jaws (59% of cases). The mass was painful in 61% of cases. Follow-up of the case reports was assessed. Recurrence occurred in 36% of cases. Distant metastases occurred in 39% of cases, most commonly to the lungs. Cervical nodal metastasis was reported in 15% of cases. The 5-year survival rate determined on cases with adequate follow-up (n = 13) was 23% free of disease, 8% alive with disease and 69% who died of disease. In comparison with stage I and stage II tongue squamous cell carcinomas, the intraoral LMS is very aggressive. It is best treated surgically, early and aggressively.
