11/939. A case of large cell calcifying sertoli cell tumor in a child with a history of nasal myxoid tumor in infancy.

    A case of an 8-year-old Japanese boy with a testicular large cell calcifying sertoli cell tumor (LCCSCT) is presented. This report appears to be the first Japanese case of LCCSCT. The patient presented with left testicular swelling and gynecomastia. His family history was not contributory; however, his past history was remarkable for a benign myxoid tumor in the nasal cavity, which was removed at the age of 2 months. After removal of the testicular tumor, the gynecomastia disappeared gradually and no recurrence or metastasis developed during a 15 month follow-up period. Although the tumor was initially interpreted as a leydig cell tumor, a review of the slides after the patient's past history of nasal myxoid tumor was revealed led us to the diagnosis of LCCSCT. An accurate diagnosis of LCCSCT is crucial because this tumor is occasionally associated with carney complex, which can comprise various pathological conditions, including cardiac myxoma, that may be life-threatening. myxoma of carney complex has been described to occur in the heart, skin, oral cavity and breast in a wide age range, but there have been no reports referring to nasal myxoid tumor associated with carney complex.

12/939. Metastasis of a renal cell carcinoma to the nose and paranasal sinuses.

    We present a case of a metastasis of a renal cell carcinoma to the nose and paranasal sinuses. A 66 year old male patient developed a mass in his left nasal cavity and paranasal sinuses, five years after he underwent a left sided nefrectomy for a renal cell carcinoma. The histopathologic examination of the nasal mass showed metastasis of a renal cell carcinoma. A craniofacial resection was performed followed by radiotherapy.

13/939. Nasal haemangiopericytoma: report of two cases with literature review.

    Haemangiopericytoma (HPC) is a rare vascular tumour produced by proliferation of pericytes. One hundred and thirty-three cases of HPC have been reported in the nose and the paranasal sinuses. We present two more cases. Wide surgical excision via lateral rhinotomy, midfacial degloving, or endonasal removal is the treatment of choice. radiotherapy has been used post-operatively in cases of incomplete removal. life-long follow-up is required to evaluate local recurrence and late metastases.

14/939. CT of intranasal pleomorphic adenoma.

    Intranasal pleomorphic adenoma is rare. We report the CT features this tumor in a 41-year-old woman who presented to us with right nasal obstruction and a 2-day history of epistaxis.

15/939. CT and MRI of congenital sinonasal ossifying fibroma.

    We report a 9-year-old boy with a sinonasal ossifying fibroma, probably congenital, with atypical findings on CT and MRI. CT revealed a soft-tissue density mass in the sphenoethmoidal sinuses, nasal cavity and right maxillary sinus with a few foci of calcification and with remodelling and destruction of the adjacent facial bones. MRI showed high signal on T2- and intermediate signal on T1-weighted images. A thin, partly enhancing outer shell and some nonenhancing septa were visible on contrast-enhanced images. MRI also showed the tumour to extend into the anterior cranial fossa. Subtotal removal was performed. We compare our findings with reports in the literature and discuss the differences from fibrous dysplasia.

16/939. Use of the nasal SMAS to reconstruct defects of the tip, alae, columella, or septum.

    Reconstruction using traditional methods for small and medium-sized losses of the soft tissues of the lower third of the nose, including the tip, the columella, alae, or the cartilaginous septum, has meant leaving cicatricial stigmata surrounding the region and has required at least two operational stages. A comprehensive study of the local anatomy was completed, and a specific technique (presented herein) was used to transfer and distribute the well-vascularized layer of superficial muscle and aponeurotic tissue (SMAS) from the dorsum of the nose to the needed site, which provided bulk and a well-nourished surface that could be covered by a distant skin graft, using a one-step flap. The surgical approach to the SMAS was carried out through the scar over the site of tissue loss or through the site of regional ablation or the traumatic wound. Several representative cases are presented.

17/939. Mucocutaneous angiomyolipoma. A report of 2 cases arising in the nasal cavity.

    OBJECTIVE: angiomyolipoma (AML) is a distinctive tumor that usually occurs in the kidney and rarely in the liver. angiomyolipoma of other sites is extremely rare, and, to our knowledge, only 2 cases have been described in the nasal cavity. We present 2 additional cases of AML of the nasal cavity and discuss the difference between them and renal AML. case reports AND PATHOLOGIC FINDINGS: Two tumors in a 66-year-old man and an 88-year-old woman without tuberous sclerosis are described. They showed 20-mm, well-circumscribed, polypoid shapes. Histologically, they were composed of mature smooth muscle cells, fat cells, and various-sized blood vessels. In addition, aggregated small lymphocytes were noted. Neither epithelioid smooth muscle cells nor HMB45 immunoreactivity was seen in either case. CONCLUSIONS: The clinicopathologic features of AML of the nasal cavity are distinct from renal and hepatic AML and are common to those of AML arising in the skin and oral and pharyngeal mucosa. The term mucocutaneous angiomyolipoma is thought to be appropriate to express these characteristic tumors.

18/939. Endoscopically assisted anterior cranial skull base resection of sinonasal tumors.

    The traditional approach to sinonasal tumors involving the base of skull has been the anterior craniofacial resection. Endoscopic techniques have created the potential to approach the intranasal aspect of skull base lesions without external incisions and still develop an en bloc resection when removed. We report our initial experience with skull base neoplasms in which the otolaryngic portion of the standard resection was accomplished instead through an endoscopic approach. The nature of lesions favorable for this approach and associated technical issues are discussed. Although we do not consider this approach a replacement for the traditional anterior craniofacial resection, it is an important adjunct in the skull base surgeon's armamentarium.

19/939. ameloblastoma with basal cell carcinoma-like feature emerging as a nasal polyp.

    A case of a 63-year-old man with ameloblastoma with basal cell carcinoma (BCC)-like features clinically emerging as a nasal polyp is reported. The left nasal cavity was filled with a solid mass, which seemed to be a sinusitis-associated nasal polyp. The polyp was covered by parakeratotic squamous epithelium which was directly connected to the BCC-like tumor nest. The BCC-like features gradually changed to adamantinoid features. The polyp was connected with a huge mass filling the maxillary sinus and the molar area, which consisted of conventional ameloblastoma features. Although the tumor was finally diagnosed as an ameloblastoma of the maxilla, the biopsy specimen forced us to face the problem of differential diagnosis, ameloblastoma with BCC-like features or adamantinoid basal cell carcinoma (BCC). Immunohistochemical examination revealed that tumor cells of the ameloblastoma reacted with anticytokeratin antibody KL-1 but not with antiepithelial antibody Ber-EP4, and these reaction patterns were completely contrary to those of BCC. It is emphasized that immunohistochemical examination using anticytokeratin antibody KL-1 and antiepithelial antibody Ber-EP4 is a good tool for distinguishing ameloblastoma with BCC-like features from adamantinoid BCC.

20/939. Pleomorphic adenoma of the nasal septum.

    Pleomorphic adenoma is the commonest benign tumour of the major salivary glands. It can also occur in minor salivary glands, mainly in the oral cavity, but also in other sites in the head and neck both within and outwith the upper aerodigestive tract. We present a rare case of pleomorphic adenoma of the nasal septum with consideration of the clinical management and a review of the literature.
