1/53. Genital angiofibromas in tuberous sclerosis: two cases.

    Cutaneous lesions are an important feature of tuberous sclerosis (TS). Facial angiofibromas usually begin to appear at the end of the first decade of life and are considered to occur in about 88% of adults with TS. They are only rarely reported on sites other than the face or front. In this paper, we report two patients with the complete syndrome of TS that had, in addition to classic facial lesions, multiple papules on the genital area. Histopathology confirmed the diagnosis of angiofibroma. One patient's lesions were misdiagnosed as genital warts and were so being treated before the correct diagnosis was made. Although we don't know the incidence of genital angiofibromas in TS patients, we believe that they might be underreported, because dermatologists generally don't look for them when they see these patients.

2/53. Application of artificial dermis prior to full-thickness skin grafting for resurfacing the nose.

    Two patients with nasal skin defects resulting from excision of rhinophyma and multiple angiofibromas were treated with artificial dermis followed by full-thickness skin grafts taken from the postauricular region. The secondary skin grafts took completely in both patients, and the postoperative results were excellent. Although a two-stage operation is required, application of artificial dermis prior to full-thickness skin grafting is a reliable method for resurfacing the nose.

3/53. Angiectatic nasal polyps that clinically simulate a malignant process: report of 2 cases and review of the literature.

    BACKGROUND: Approximately 5% of inflammatory or allergic sinonasal polyps develop extensive vascular proliferation and ectasia with deposition of pseudoamyloid. These so-called angiectatic nasal polyps (ANPs) can grow rapidly and exhibit an aggressive clinical behavior that could simulate malignancy preoperatively. OBJECTIVE: To systematically address the differential histologic diagnosis of ANPs. methods: We evaluated by light microscopy, immunohistochemistry, and electron microscopy biopsy and resection specimens from 2 large ANPs (8 and 10 cm in diameter) that presented in 2 adult men with life-threatening epistaxis and facial deformity, respectively. RESULTS: The tumors were firm, lobulated, and covered by smooth, partially ulcerated mucosa. Histologically, clusters of dilated, thin-walled blood vessels embedded in pools of congo red-negative eosinophilic material, associated with patchy necrosis and atypical stromal spindle cells, were seen. Electron microscopy and immunohistochemistry (CD34, factor viii) confirmed the endothelial nature of the cells lining the spaces, whereas the atypical stromal cells were classified as myofibroblasts. CONCLUSIONS: These 2 cases represent extreme examples of ANPs that clinically simulate a malignant process. awareness of the histological features of ANPs should prevent confusion of such lesions with other vascular or spindle cell lesions of the nasopharynx that would require different treatment and carry a different prognosis.

4/53. The use of intensity modulated radiotherapy for the treatment of extensive and recurrent juvenile angiofibroma.

    These case series are presented to describe the application and advantages of intensity modulated radiotherapy (IMRT) for the treatment of extensive and/or recurrent juvenile angiofibroma. Two patients were diagnosed with recurrence at 11 and 13 months postoperatively, and one was surgically unresectable. The affected areas included the base of skull, cavernous sinus, pterygopalatine fossa, infratemporal fossa, posterior orbit and nasopharynx. Highly conformal IMRT was delivered with limited radiation doses to the optic nerves, optic chiasm, brainstem, brain, spinal cord, lens, retina, mandible, and parotid. The total dose delivered to the tumor varied from 3400 to 4500 cGy. The tumor shrunk radiographically in all three cases and there was no endoscopic evidence of disease in two cases at 15 months and 40 months. There was no acute toxicity. Late toxicity was limited to one episode of epistaxis and persistent rhinitis in one patient. In conclusion, IMRT provides several advantages over conventional radiotherapy in the treatment of recurrent juvenile angiofibroma.

5/53. Endoscopic sinus surgery for juvenile nasopharyngeal angiofibroma.

    Juvenile nasopharyngeal angiofibroma is a rare tumour of the head and neck with very specific characteristics: adolescent males, choana-nasopharynx, pterygomaxillary fossa widening, specific and intense vascularisation. Staging is very important in the decision of the surgical approach. Endoscopic management of juvenile nasopharyngeal angiofibroma is technically possible after preoperative embolisation. Up to now 13 angiofibroma have been treated using the endonasal endoscopic sinus surgery approach in belgium (Leuven 8; Mont-Godinne 2; Ghent 1; Liege 1; Woluwe 1). In smaller tumors endoscopic resection has been successful in four cases without any recurrence. Five larger tumors, extending in the pterygomaxillary fossa, were also successfully resected. Extension into the infratemporal fossa or the cavernous sinus can be endoscopically removed, but recurrences may occur as they do after classical, external approaches. In conclusion, the endoscopic approach is an acceptable alternative in small to middle sized juvenile nasopharyngeal angiofibroma.

6/53. Extranasopharyngeal angiofibroma arising from the nasal septum.

    Extra nasopharyngeal origin of angiofibroma is very rare. The nasal septum is a very rare site of extra nasopharyngeal angiofibroma with only two cases reported in the medical literature. We report here a case of a vascular mass arising from the nasal septum of an 8 year old boy. Histopathology confirmed it to be a case of angiofibroma. A review is also made of the other reported cases of angiofibroma arising from the nasal cavity. The likely theory of origin of the tumor and the management is also discussed.

7/53. Angiomyofibroblastoma of the vulva: report of a case.

    A 45-year-old woman was first seen by us 2 years after becoming aware of a slightly painful subcutaneous mass in her left vulva. The mass was 7.5 x 3.0 cm in size, well circumscribed, mobile, and rubbery. It was at first clinically considered to be a benign tumor. Microscopically, the resected mass was composed of spindle or polygonal tumor cells which were cellularly or hypocellularly arranged with perivascular accentuation in a mucoid or fibrocollagenous background. Immunohistochemically, myxoid tumor cells were positive for vimentin but not for alpha-smooth muscle actin, CD34, CD31, desmin, or S-100 protein. The tumor was diagnosed as an angiomyofibroblastoma (AMBF), based on the typical findings of histology and immunohistochemistry. There are many histological types of vulvar tumors, and establishing a preoperative diagnosis is difficult in many patients. Rapid intraoperative pathological diagnosis should be performed if possible, considering the possibility of diseases such as AMFB and aggressive angiomyxoma (AAM). When AAM is suspected, the peripheral tissues should also be resected to prevent recurrence.

8/53. Juvenile nasopharyngeal angiofibroma presenting as Foster Kennedy syndrome.

    Juvenile nasopharyngral angiofibroma (JNA) is a rare benign tumor of the nasopharynx that occurs in adolescent boys with epistaxis and nasal obstruction. It may grow into the cranium causing elevated intra-cranial pressure and compression on the optic nerve. A histological-proven case of JNA in an 18 year-old Ethiopian boys is presented. He became blind due to optic atrophy in the right eye, but salvaged a useful vision in the left eye radiotherapy. The possibility of Foster-Kennedy syndrome, a presentation of one atrophic and one papilloedematous optic nerve head of bilateral asymmetric optic atrophy, is discussed. Controversies about its histological appearance, natural history, diagnostic methods and management modalities are reviewed. JNA should be considered in adolescent boys who present with optic atrophy and/or nasal mass. Early detection and initial surgical treatment with adjunct radiotherapy could have prevented visual loss on this boy.

9/53. Lipomatous variant of nasopharyngeal angiofibroma: a case report.

    Nasopharyngeal angiofibroma is an uncommon benign vascular tumor that occurs in adolescent boys and young men. We describe an unusual histological variant of this entity characterized by a prominent adipose tissue component. The patient was a 35-year-old man with a 20-year history of nasal obstruction. Results of physical examination and angiography demonstrated a nasal mass consistent with a nasopharyngeal angiofibroma. We discuss the differential diagnoses pathologically for this lesion.

10/53. Juvenile angiofibroma: case report and the role of endoscopic resection.

    Juvenile angiofibroma is benign yet aggressive. Due to its inaccessible location in the nasopharynx, open surgery usually requires osteotomies which cause stunting of facial growth in adolescent males. Advances in imaging and treatment techniques have now facilitated more accurate staging of this disease. For small, extracranial tumours limited to the nasal cavity and paranasal sinus, endoscopic resection is a viable alternative. This case report will illustrate how endoscopic resection allows good control with minimal morbidity compared to open surgery or radiotherapy.
