11/124. Basal cell carcinoma on the vermilion border of the lip: a study of six cases.BACKGROUND: The vermilion border of the lower lip is a frequent location of squamous cell carcinoma (SCC), but it is very rarely mentioned within the published series of basal cell carcinomas (BCCs). OBJECTIVE: We present 6 cases of BCC involving either mainly or exclusively the vermilion border of a lip. methods: We reviewed from our files all the cases of BCC diagnosed in a period of 11 years. RESULTS: A number of 3,477 BCCs were histologically diagnosed in that period; 2,872 (82.6%) of them were located on the head, and 66 (2.3%) of the latter (1.9% of all BCCs) were on the lips. In 6 cases, the neoplasm involved either mainly or exclusively the vermilion border of either the lower (5 cases) or the upper (1 case) lip. CONCLUSION: Not every carcinoma of the vermilion border of the lip is a SCC.- - - - - - - - - - ranking = 1keywords = lower (Clic here for more details about this article) |
12/124. Modified bilateral neurovascular cheek flaps: a new technique for reconstruction of extensive upper lip defects.The authors present a modified bilateral neurovascular cheek flap as a new technique for extensive upper lip reconstruction. The technique is modified from the bilateral neurovascular cheek flap for lower lip reconstruction described by Vatanasapt and colleagues in 1987 by designing rectangular and triangular flaps in the cheek tissues lateral to the lip defect on both the skin and the mucosal sides. This method has the advantage of preserving neurovascular structures as well as the original position of the oral commissure. Five patients are presented with acceptable surgical results. The technique is a good choice for functional reconstruction of near-total or total upper lip defects.- - - - - - - - - - ranking = 0.5keywords = lower (Clic here for more details about this article) |
13/124. Primary reconstruction of defects in the upper and lower lips following tumor excision.Three cases of basal cell carcinoma and epithelioma in the upper and lower lips are reported. The defects in the upper lip following tumor excision were repaired with an application of Burow's technique. Martin's method, after modification of Bernard cheiloplasty, was used for the repair of the lower lip defect. The methods proved to be quite effective in providing excellent aesthetic results. No disturbance was noted in the activity of the repaired upper lips. The labial function, however, associated with the orbicularis oris was left impaired in the newly formed lower lip.- - - - - - - - - - ranking = 3.5keywords = lower (Clic here for more details about this article) |
14/124. Reconstruction of total lower lip, labial commissure and palatomaxillary defect with composite island cheek flap.Functional and cosmetic restoration of total lower lip, labial commissure, and palatomaxillary defects can be achieved by using multiform flaps. The possibility of reconstruction of these areas with composite island cheek flap is presented. The flap was used in three patients who were surgically treated between 1993 and 1998. In one female patient, total lower lip and chin defect was restored with a small contralateral platysma muscle cutaneous flap. The functional and cosmetic result was achieved with composite island cheek flap. In the other two cases, reconstruction was performed without another flap. Composite island cheek flap is supplied with bloody by the facial artery and vein, and contains mucous membrane, muscle and skin of the cheek. In two cases, the flap was formed by the anterior part of the buccal muscle, and in the case with the reconstruction of labial commissure, the greater and lesser zygomatic muscles with levator muscle of the angle of mouth were used. By freeing the blood vessels from the surrounding structures, isolation and transsection of minor vessel branches allowed straightening of the tortuous main vessels. With this technique, excellent functional and satisfactory cosmetic results were achieved in a single act, with minimal morbidity for labial commissure, and total lower lip or palatomaxillary defect reconstruction.- - - - - - - - - - ranking = 3.5keywords = lower (Clic here for more details about this article) |
15/124. Metachronous multiple carcinoma of lip after surgery for gingival carcinoma: a case report.A case of multiple carcinoma of the lower lip probably induced by repeated bite trauma due to lack of sensation is reported. A reduction in immunocompetence by carboplatin (CBDCA) might be an additional condition for the carcinogenesis. This case suggests that the reconstruction of the sensory nerve is important after resection of a malignant tumor of the head and neck region.- - - - - - - - - - ranking = 0.5keywords = lower (Clic here for more details about this article) |
16/124. Reconstruction of the labiomental region with local flaps.BACKGROUND: Reconstruction of the labiomental area presents certain difficulties, especially in the assessment and selection of the incision lines to obtain the best cosmetic result. Among the factors influencing the selection of a reconstruction technique are the presence of natural folds and creases, skin laxity, and the size, shape, and orientation of the wound. Many operative techniques have been described for the reconstruction of this region. OBJECTIVE: To describe a combination of reconstruction techniques which restore the form, preserve sensation, and provide function of the labiomental region after ablative surgery. methods: We present two patients with reconstruction of the labiomental area where it was possible to preserve the vermilion of the lower lip after wide excision. The method of reconstruction constitutes a of modification of the Bernard method and Schuchardt procedure. RESULTS: Satisfactory results were obtained with preservation of the sensitivity of the lower lip, competent lip seal, and avoidance of microstomia, in addition to a good aesthetic appearance. CONCLUSION: The described technique is a preferable technique in patients for whom vermilion of the lower lip should be preserved after wide excision. The technique restores the form, preserves sensation, and provides function-the principles of a successful reconstruction.- - - - - - - - - - ranking = 1.5keywords = lower (Clic here for more details about this article) |
17/124. Atypical lipomatous tumor of the lip with pleomorphic lipoma-like myxoid area, clinically simulating mucocele.Lipomatous tumor is least common in the oral cavity. We present a case of atypical lipomatous tumor arising in the lower lip of an 81-year-old male. Clinical diagnosis was mucocele. The tumor measured 12 mm in diameter with a round shape. It was solid, firm, myxomatous and translucent with a small yellowish focus in the central portion. Histologically, the tumor was a circumscribed and well-encapsulated mass with prominent myxoid matrix. The central minor portion showed a well-differentiated liposarcoma. In the myxoid area, lipoblasts and large atypical cells with dense chromatin including floret-like giant cells were seen in abundance. Atypical lipomatous tumor may be indistinguishable from pleomorphic lipoma and its distinction from the latter is based on location as well as relative abundance of floret-type giant cells and lipoblasts. According to its abundance in lipoblasts over floret-like cells, pleomorphic lipoma-like area in our case could also be a part of atypical lipomatous tumor. It may be possible to interpret myxoid change in our case as to represent a superficial counterpart of myxoid malignant fibrous histiocytoma-like change reported in the retroperitoneal lesion.- - - - - - - - - - ranking = 0.5keywords = lower (Clic here for more details about this article) |
18/124. Malignant melanoma of the lip spreading in a pagetoid manner into the minor salivary glands.We describe a malignant melanoma of the lower lip that upon recurrence extended in a pagetoid manner into the ducts of the oral minor salivary glands. immunohistochemistry with antibodies to MART-1 and HMB-45 confirmed that the atypical cells in the ducts of the salivary glands were indeed melanoma cells. Pathologists involved in staging of oral melanoma are urged to look out for this previously unreported mode of spread of labial malignant melanoma.- - - - - - - - - - ranking = 0.5keywords = lower (Clic here for more details about this article) |
19/124. Microcystic adnexal carcinoma: an unusual cause of swelling and paraesthesia of the lower lip.Microcystic adnexal carcinoma (MAC) is an uncommon, recently described, cutaneous adnexal malignant neoplasm, associated with significant morbidity as a consequence of its propensity for perineural invasion. The present report details the clinical and histological features of MAC in a young female presenting with lower labial swelling and paraesthesia.- - - - - - - - - - ranking = 2.5keywords = lower (Clic here for more details about this article) |
20/124. Malignant conversion of florid oral and labial papillomatosis during topical immunotherapy with imiquimod.We report a case of a 61-year-old woman suffering from florid oral papillomatosis with a squamous-cell cancer of the floor of the mouth, which was removed by scalpel surgery combined with a radical neck dissection in 1996. Between 1996 and 2000 several histologically benign papillomatous lesions of mouth and lips were removed with laser and electrosurgery. However, the lesions recurred. In July 2000 hyperkeratotic, wart-like lesions were present at the lower and upper lips and at the right angle of the mouth and the adjacent oral mucosa. Overnight treatment with a topical 5% imiquimod cream on a Monday-Wednesday-Friday schedule was initiated. However, due to severe irritation and pain the application had to be reduced to 4 h per night, three times a week, followed by a therapy-free interval of 2 weeks. Despite this treatment consisting of four cycles of 3 weeks (1 week treatment and 2 weeks pause), the lesions increased markedly in size. A biopsy taken from the tumorous lesion from the right angle of the mouth proved to be a squamous-cell carcinoma. The tumors of the labial and oral mucosal sites as well as the right submandibular lymph nodes were removed by wide scalpel excision. The lips were reconstructed by plastic surgery. 24 months after surgical intervention no recurrence nor metastasis to lymph nodes or distal sites were observed.- - - - - - - - - - ranking = 0.5keywords = lower (Clic here for more details about this article) |
