1/84. Patient with lichen planus and conjunctival immunopathologic features of lupus erythematosus.PURPOSE: To report a case of severe cicatricial conjunctivitis in a patient with lichen planus, which is known to affect the skin and mucous membranes. The conjunctival immunopathologic features were consistent with lupus erythematosus rather than with lichen planus. METHOD: Oral mucosal and skin biopsies were performed with histopathologic and immunofluorescent studies consistent with lichen planus. The patient later had a biopsy of cicatrized conjunctiva with histopathologic and immunofluorescent findings consistent with lupus erythematosus. Evaluation by rheumatology and dermatology consultants demonstrated no evidence of active systemic lupus erythematosus or discoid lupus erythematosus. RESULTS: The patient was treated with topical and systemic immunosuppressives and her disease eventually stabilized. CONCLUSION: The case demonstrates two coexisting autoimmune disease entities: lichen planus of the skin and oral mucosa and a cicatricial conjunctivitis consistent with lupus erythematosus.- - - - - - - - - - ranking = 1keywords = mucous membrane, mucosa, membrane (Clic here for more details about this article) |
2/84. Linear IgA disease.PURPOSE: A case of linear IgA disease is reported to alert ophthalmologists and physicians to this unusual cause of chronic cicatrizing conjunctivitis. methods: Clinical records of a patient suffering from linear IgA disease were reviewed. RESULTS: A 65-year-old woman with a complicated medical history experienced rapidly progressive chronic cicatrizing conjunctivitis leading to corneal perforation. Undiagnosed gingivitis and palatal ulceration had been present for 5 years prior to the onset of ocular symptoms and vitamin C deficiency had followed the consequent dietary restrictions. A diagnosis of linear IgA disease was made on conjunctival biopsy, which demonstrated linear deposits of IgA along the epithelial basement membrane. The perforation was managed successfully with a conjunctival pediculate flap. Control of the inflammation was achieved with systemic prednisolone and cyclophosphamide but at the expense of serious systemic side-effects. CONCLUSIONS: Linear IgA disease causes progressive conjunctival cicatrization in many affected individuals.Although dapsone generally controls the inflammation, heavier systemic immunosuppression was required in this case. Involvement of skin or other mucosal surfaces may become symptomatic before the conjunctivitis, and physicians must be educated to refer patients for ophthalmological review on diagnosis. Conversely, ophthalmologists encountering ocular linear IgA disease should be aware of the possibility of other mucosal involvement requiring physician intervention.- - - - - - - - - - ranking = 0.091331170427232keywords = mucosa, membrane (Clic here for more details about this article) |
3/84. granular cell tumor of the hypopharynx treated by endoscopic CO(2) laser excision: report of two cases.BACKGROUND: granular cell tumor (GCT), or Abrikossoff's tumor, is an unusual lesion probably arising from schwann cells. It is frequently found in the head and neck region, where the tongue is the most commonly affected site. Involvement of the hypopharynx is exceedingly rare because, to the best of our knowledge, only four cases have been reported in the literature. methods: We describe hypopharyngeal GCT in two women aged 29 and 52 years, respectively. RESULTS: In the first patient, preoperative diagnostic examination, including endoscopy, CT, and MRI scan, was suggestive of a benign lesion arising from the posterior wall of the hypopharynx. In the second patient, a previous biopsy of the postcricoid area performed elsewhere suggested a diagnosis of well-differentiated squamous cell carcinoma, and CT scan staged the lesion as T1 N0. In both cases, treatment included surgical excision under microlaryngoscopy with CO(2) laser. The histopathologic study of the specimens, supported by immunohistochemical techniques, determined the lesions to be a GCT. The postoperative course was uneventful, and the patients were discharged 12 and 2 days after surgery, respectively. Both patients were asymptomatic without evidence of recurrence when last seen 2 years and 4 months after surgery, respectively. CONCLUSIONS: GCT should be included in the differential diagnosis of submucosal hypopharyngeal lesions. endoscopy and radiologic imaging do not display any typical finding suggestive of the diagnosis, which can be based only on histologic findings. Resection of the tumor, when technically feasible, should be performed under microlaryngoscopy with the CO(2) laser, which makes it possible to work in a bloodless field with minimal thermal damage and reduction of scarring and postoperative edema.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
4/84. Addison's disease: the potentially life-threatening tan.Addison's disease is a potentially life-threatening endocrine disorder. The classic dermatologic sign of Addison's disease is diffuse hyperpigmentation of the skin with focal hyperpigmentation of scars, nails, and the oral mucosa. Recognition of these dermatologic manifestations in a patient with otherwise vague constitutional symptoms warrants a consideration of Addison's disease.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
5/84. pemphigus vulgaris occurring simultaneously on a recent and an old surgical scar due to a Koebner's phenomenon.pemphigus vulgaris is an autoimmune bullous disorder involving the skin and sometimes the mucosa. Koebner's phenomenon is encountered when the typical features of a dermatosis are observed on a part of the skin previously subject to friction or trauma. A few cases of pemphigus vulgaris developing after damage to the skin and especially scars have been described. To the best of our knowledge, we report the first case where typical lesions of pemphigus vulgaris appeared simultaneously on a recent and an old scar as the sign of the reactivation of the disease.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
6/84. "Distraction" of grafted alveolar bone in cleft case using endosseous implant.OBJECTIVE: Presentation of a specific surgical technique of vertical alveolar ridge distraction performed on an alveolar bone graft 1 year after the primary grafting procedure designed to correct a labioalveolar cleft. The graft had not obtained the results desired and presented heavily scarred mucosal tissue. TECHNIQUE: A dental implant placed within the graft once it has been entirely freed by osteotomies functions as an endless screw. To avoid vascular risk, the alveolar bone graft is detached as a whole along its total height. Consequently, no bone remains above it to provide support for a conventional alveolar distractor. An osteosynthetic miniplate, fastened in a horizontal position beneath the nasal mucosae above the graft, is used to replace the missing bony support and to stabilize the implant, which activates the distraction process. PATIENT: This study is based on our first clinical case with a follow-up of 18 months at present. RESULT: A vertical displacement of the entire graft was achieved, including its attached mucosal layer, which repositioned both bone and mucosa on a far better level in the cleft area. Thus, a normal length of abutment was obtained permitting prosthetic rehabilitation based on the same endosseous implant, which was left in place within the graft. CONCLUSION: This technique may prove particularly helpful in certain cases in which a primary alveolar bone grafting procedure has produced borderline results. In such cases, on the one hand, neither the reasonably satisfactory volume of the bone graft itself nor the poor quality of its scarred mucosal tissue argue in favor of a secondary grafting procedure. On the other hand, it is impossible to resort to currently available alveolar distracters since our choice of techniques leaves no bone support above the graft.- - - - - - - - - - ranking = 0.15968945973799keywords = mucosa (Clic here for more details about this article) |
7/84. Release of extra-articular ankylosis by coronoidectomy and insertion of a free abdominal flap: case report.INTRODUCTION: It is generally agreed that an effective treatment for extra-articular ankylosis may be coronoidectomy and excision of scar tissue. But these conventional procedures have shown a high rate of recurrence of ankylosis due to heterotopic bone and fibrous tissue formation. OBJECTIVE AND PATIENT: We report a case in whom a coronoid osteotomy and insertion of a free abdominal flap was used to treat ankylosis of the mandible following radiotherapy for maxillary cancer. RESULTS: This procedure prevented recurrence of ankylosis by heterotopic bone and fibrous tissue formation. In addition, this flap reduced the risk of postoperative infection and promoted primary healing. CONCLUSION: The procedure, coronoidectomy and insertion of a free flap, was successful because the well-vascularized musculocutaneous flap occupied the dead space, and replaced the shortage of oral mucosa consequently inhibiting the recurrence of extra-articular ankylosis.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
8/84. endometriosis on laparotomy scar. A three-case report.endometriosis of surgical scar is a rare late complication of cesarean section. 3 cases of endometriosis after Pfannenstiel-type laparotomy are reported. The typical surgical presentation, present in all 3 cases, is a nodule on laparotomy scar after cesaren section, spontanously painful during the menstrual period. Ultrasound, performed in two cases, and cytological examination, performed in one, proved to be ineffective in establishing the diagnosis. The histopathological analysis of surgical specimens revealed in all cases multiple foci of well developed endometrial tissue scattered in a sclerotic stroma. Both stromal and glandular components of the endometrial mucosa were present showing the typical changes of the various phases of the menstrual cycle. In our opinion, an accurate clinical history should directly lead the surgeon to the excision with inclusion of the needle tract, whenever biopsy is performed. Surgical excision is at present the most appropriate diagnostic and therapeutic procedure.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
9/84. Chronic cicatrizing conjunctivitis in a patient with ocular cicatricial pemphigoid and fatal wegener granulomatosis.PURPOSE: To describe a case of chronic cicatrizing conjunctivitis in a patient with ocular cicatricial pemphigoid and wegener granulomatosis. methods: Observational case report. A retrospective study. RESULTS: An 80-year-old man presented with chronic cicatrizing conjunctivitis, peripheral corneal thinning, and wegener granulomatosis, which were diagnosed by his referring physician based on clinical (recurrent epistaxis, sinus congestion) and histopathologic features of nasal mucosa (granulomatous inflammation, vasculitis). A conjunctival biopsy performed by us disclosed features of active wegener granulomatosis and ocular cicatricial pemphigoid, which indicate lack of control of both diseases with methotrexate treatment. The patient died of pulmonary complications from Wegener granulomatosis 1 week after our evaluation. CONCLUSION: Ocular cicatricial pemphigoid and wegener granulomatosis are both potentially fatal autoimmune diseases. Ocular involvement in wegener granulomatosis indicates poor control of the underlying systemic condition and is a marker for active vasculitis, which indicates the need for treatment with cyclophosphamide.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
10/84. Use of hard palate grafts for treatment of postsurgical lower eyelid retraction: a technical overview.Lower eyelid retraction occasionally occurs following the repair of fractures involving the orbital rims, orbital floor, or complex zygomatic maxillary complex fractures. The surgical repair of these scarred eyelids has been historically difficult. The authors have utilized the principle of releasing the scar tissue and attempting to reposition the eyelid in its normal anatomic position by employing a hard palate mucosal graft spacer to correct the eyelid malposition. In this article, the authors discuss the excellent success they have experienced utilizing hard palate autologous grafts as spacers performing revision of scarred contracted lower eyelid retractors and tightening of the lateral canthal tendon complex. Adherence to the principles delineated in the article can yield excellent functional and cosmetic results.- - - - - - - - - - ranking = 0.031937891947598keywords = mucosa (Clic here for more details about this article) |
