1/267. Microsurgical reconstruction in recurrent oral cancer: use of a second free flap in the same patient.Primary microsurgical reconstruction is the treatment of choice for ablative defects of oral carcinoma. As a result of this trend, more and more patients with recurrent oral carcinoma who have been initially treated with surgical excision and reconstructed with free flaps are being seen. However, a second microsurgical reconstruction attempt in these cases raises questions about the flap choices, availability of recipient vessels, and effects of previous treatment modalities. Herein, 35 patients with perioral carcinoma who had two successive tumor resections and reconstruction with free flaps on each occasion are presented. A total of 75 free tissue transfers were carried out for the first and second reconstructions. After the first tumor resection, 28 radial forearm fasciocutaneous flaps, 7 fibula osteoseptocutaneous flaps, 1 iliac osteomyocutaneous flap, and 2 rectus abdominis myocutaneous flaps were used. For reconstruction after the recurrence, 17 radial forearm fasciocutaneous flaps, 13 fibula osteoseptocutaneous flaps, 3 rectus abdominis myocutaneous flaps, 2 anterolateral thigh flaps, 1 jejunum flap, and 1 tensor fasciae latae flap were used. More vascularized bone transfers were performed during the second reconstruction since the excision for the recurrence frequently required segmental mandibulectomy. The complete flap survival rate was 97.3 percent and 94.6 percent with a reexploration rate of 7.9 percent and 13.5 percent for the first and second free tissue transfers, respectively. The mean follow-up time throughout the procedures was 37.5 months. disease-free interval between reconstructions was 20.8 months. At the time of evaluation, 54.3 percent of the patients were surviving an average of 19 months since the second reconstruction. The results suggest that free flaps represent an important option in reconstruction of recurrent perioral carcinoma cases undergoing reexcision. When used in this indication they are as safe and effective as the initial procedure.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/267. Solitary fibrous tumor of the oral cavity: an uncommon location for a ubiquitous neoplasm.Solitary fibrous tumor is an uncommon soft tissue tumor initially reported in the pleura but recently described in other sites of the body. To date, only 5 examples of oral solitary fibrous tumor have been reported. Here, we describe 2 additional cases of this tumor in the oral cavity. The tumors were composed of small to medium-sized spindle cells with bland cytologic features; these cells were haphazardly arranged in highly cellular sheets or ill-formed fascicles as well as in hypocellular areas with hyalinized blood vessels. Both tumors contained blood vessels with a hemangiopericytomalike appearance and expressed vimentin, CD34, and CD99. One case was also strongly positive for bcl-2. The diagnosis of solitary fibrous tumor may be difficult inasmuch as it shares a number of histologic features with other soft tissue tumors. awareness of its occurrence in the oral cavity is important so that confusion with other spindle cell neoplasms can be avoided.- - - - - - - - - - ranking = 46.102816314531keywords = neoplasm (Clic here for more details about this article) |
3/267. The lateral tongue flap: a salvage option for reconstruction of buccal recurrences.BACKGROUND: Surgery in an irradiated, previously operated field is fraught with danger. Though microvascular tissue transfers are being gone, they may not be feasible in all circumstances. methods: A lateral tongue flap was executed in 11 cases of intraoral buccal recurrence. The aims of this study were to evaluate the procedure, the function of the remaining tongue and the speed of rehabilitation with respect to preoperative functional status. RESULTS: Out of 11 such reconstructions in a period of 12 months, only 1 flap had tip necrosis while a haematoma developed in 2 cases. Swallowing, speech, and tongue protrusion were not significantly hampered by the procedure. patients were rehabilitated very quickly (within 2 weeks), to preoperative functional status. CONCLUSIONS: The Lateral tongue Flap is a simple, robust vascular transfer and an effective salvage reconstructive option in a post-excisional defect caused by a recurrent intraoral cancer.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |

Benign mesenchymoma of the cheek: report of a case and review of the literature.Benign mesenchymoma is a soft tissue neoplasm that contains 2 or more differentiated mesenchymal components in addition to fibrous tissue. A rare case of benign mesenchymoma of the cheek in a 6-year-old boy is presented. The literature pertaining to mesenchymoma in the head and neck region is reviewed and discussed.- - - - - - - - - - ranking = 9.2205632629063keywords = neoplasm (Clic here for more details about this article) |
5/267. Transmucosal fine-needle aspiration diagnosis of intraoral and intrapharyngeal lesions.OBJECTIVES: The effectiveness of fine-needle aspiration biopsy (FNAB) for the diagnosis of neck, thyroid, and salivary gland masses is well documented. Very few reports explore the potential of an intraoral FNAB approach for the diagnosis of submucosal lesions. We describe our technique and present case examples of pertinent differential diagnostic entities. We recommend an expanded role for FNAB of the oral cavity and oropharynx. STUDY DESIGN: Retrospective review. methods: A uniform technique was employed for transmucosal FNAB of 76 patients with intraoral masses. In applicable cases, cytology results were compared with traditional biopsy methods and permanent histopathologic specimens for accuracy. RESULTS: Our experience demonstrates the high sensitivity (93%) and specificity (86%) of intraoral FNAB when compared with biopsy by conventional means. FNAB provides distinct advantages for the cytologic diagnosis of submucosal lesions, which may be difficult to reach and adequately sample through conventional biopsy. FNAB of the tonsil and tonsillar fossa provides a safe and effective means of diagnosing both lymphoma and squamous cell cancer. Transmucosal FNAB via the mouth led to rapid diagnosis of a number of benign and malignant lesions. Applying this uniform FNAB technique, we had no significant complications. CONCLUSION: We recommend transmucosal FNAB as an effective means for highly accurate diagnosis of submucosal lesions of the oral cavity and oropharynx. CLINICAL RELEVANCE: Traditional biopsy techniques in the oral cavity may require anesthesia and may have diagnostic difficulties, particularly for submucosal lesions. Transmucosal FNAB overcomes these shortcomings by providing a minimally invasive means to rapid diagnosis of intraoral lesions.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
6/267. Giant cell angiofibroma of the oral cavity: report of a new location for a rare tumor.Giant cell angiofibroma is a rare, soft tissue tumor that was first described in the orbit. Since then, several case reports have described this tumor in a number of extra-orbital sites, suggesting a wider anatomic distribution than is generally recognized. The tumor typically acts in a benign fashion with only rare local recurrences but no tendency to metastatic disease. Here, we report the first case of a giant cell angiofibroma in the oral cavity. The tumor presented as a soft tissue nodule on the buccal mucosa of a 60-year-old man. The histologic differential diagnosis included a number of other uncommon soft tissue neoplasms, including giant cell fibroblastoma, solitary fibrous tumor, and pleomorphic lipoma. The histologic and immunohistochemical features of this tumor and differentiation from other histologically similar soft tissue neoplasms are briefly discussed.- - - - - - - - - - ranking = 18.441126525813keywords = neoplasm (Clic here for more details about this article) |
7/267. Oral leiomyosarcoma in childhood. Report of a case with fine needle aspiration cytology.BACKGROUND: Leiomyosarcomas are rare tumors in the pediatric age group, and occurrence of this neoplasm in the oral cavity is exceedingly rare. This article highlights the fine needle aspiration (FNA) cytology diagnosis of a case of recurrent oral leiomyosarcoma in childhood. CASE: An 11-year-old male noticed a swelling in the oral cavity near the left lower jaw. It was excised and diagnosed as leiomyosarcoma on histopathology. Four months later the patient presented with a progressive swelling in the oral cavity that extended to the lower jaw. The recurrent swelling was subjected to FNA, and its cytologic features were consistent with leiomyosarcoma. There was a very good initial response to chemotherapy and radiation therapy. However, because of noncompliance with advice for further therapy, the patient had a second local recurrence and dissemination of the disease to the skeletal system, abdomen and thorax. FNA cytology diagnosis of the second locally recurrent lesion and abdominal mass were consistent with leiomyosarcoma. Immunocytochemical staining revealed a positive reaction in the cytoplasm of tumor cells for vimentin and desmin in the FNA smear and paraffin section, respectively. CONCLUSION: Fine needle aspiration cytology is a useful technique for detection of recurrence and metastasis during follow-up of childhood oral leiomyosarcoma.- - - - - - - - - - ranking = 9.2205632629063keywords = neoplasm (Clic here for more details about this article) |
8/267. High dose rate microselectron mould ratiotherapy of a widespread superficial oral cancer.Treatment of a case of widespread superficial oral squamous cell carcinoma with external beam irradiation, followed by high dose rate Microselectron mould radiotherapy, is reported. The tumor disappeared macroscopically after treatment, but there was infield recurrence in the buccogingival sulcus where the radiation dose might have been inadequate. Apart from some radiation mucositis within the treated area, edema and a superficial ulcer were observed in the tongue. These were considered to be due to radiation overdose. Although there is room for improvement, this mode of treatment has something to offer patients with hard-to-cure cancer.- - - - - - - - - - ranking = 1.25keywords = cancer (Clic here for more details about this article) |

10/267. cryosurgery for oral cancer--a six-year retrospective study.In a review of 50 patients with oral cancer treated by cryosurgery, local control of the tumor for more than two years was achieved in 90%. In only 4 of 25 instances where the tumor had superficially invaded bone, or was adjacent to it, was resection necessary. cryosurgery was effective in controlling benign and premalignant lesions also. The treatment is often palliative and sometimes curative when patients refuse other recommended care.- - - - - - - - - - ranking = 1.25keywords = cancer (Clic here for more details about this article) |
