1/23. Primary orbital leiomyoma and leiomyosarcoma.A case of an extremely rare primary orbital leiomyoma in a 25-year-old male patient is presented who had a lifelong history of deviation of the left eye globe with slight enophthalmos and reduced motility. Because of pain and increasing deviation of the eye the tumor was totally resected. On histologic examination the tumor showed ossification which is extremely rare so that a calcifying fibroma had to be ruled out. In immunohistochemistry, however, this tumor stained with smooth muscle antigen. Less than 2% of cells stained positive for Ki-S1, a proliferation marker. The second case is a rare primary orbital leiomyosarcoma in an 84-year-old female patient that showed massive growth. After exenteration histologic examination showed a dedifferentiated highly malignant soft tissue tumor which expressed desmin and smooth muscle actin but was negative for myoglobin, S-100 and HMB-45.- - - - - - - - - - ranking = 1keywords = life (Clic here for more details about this article) |
2/23. Non-Hodgkin's lymphoma and periodontitis. A case report.BACKGROUND: We describe an unusual case of extra-nodal non-Hodgkin's lymphoma that developed in the maxillae associated with localized severe periodontitis in a 64-year-old Caucasian male. The lymphoma was diagnosed less than 2 years following routine periodontal surgery and 8 weeks after the extraction of hopeless teeth in the associated area. methods: Two months following the extractions, the patient experienced pain and swelling in the maxillary right edentulous area mimicking an abscess, and reported for emergency care. An expansile lesion measuring 2.0 x 2.5 cm in diameter was noted on radiographic examination to extend into the right maxillary sinus. A definitive biopsy diagnosis of high-grade, small, non-cleaved, diffuse non-Hodgkin's lymphoma of the right posterior maxillae was established. The patient was subsequently treated by a combination of radiation, chemotherapy, and bone marrow transplantation. RESULTS: The maxillary tissues healed uneventfully, and the patient has been closely observed for approximately 5 years without symptoms or recurrence of the lymphoma. CONCLUSIONS: This case highlights the need for careful debridement of extraction sockets associated with severe periodontitis and argues for the routine submission of extracted teeth with adjacent soft tissue for microscopic analysis, to assist in the early diagnosis of potentially life-threatening malignancies.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
3/23. Antrochoanal polyps in children: CT findings and differential diagnosis.Antrochoanal polyp (Killian polyp) is an infrequent, usually solitary, benign, slowly growing lesion that arises from the maxillary antrum and reaches the choana. These polyps have a discrete male predominance and are diagnosed usually between the third and the fifth decades of life. This report is based on three cases of antrochoanal polyp, occurring in the pediatric group, and the objective is to demonstrate their different CT characteristics, principal differential diagnoses, and potential complications. We emphasize that in all three cases of our series the growth of the polyp to the choana is through the accessory ostium.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
4/23. Rare mesenchymal lesions: hamartoma of the chest wall and juvenile active ossifying fibroma in siblings.Mesenchymal hamartomas of the thorax are known as rare dysontogenetic tumorous non-neoplastic lesions. The juvenile active ossifying fibroma (JAOF) also is considered as a benign tumor like lesion of the mesenchymal connective tissue. The authors report the cases of 2 siblings-a 2-year-old girl with a hamartoma of the chest wall and her 4-year-old brother with a JAOF. The girl had bilocular mesenchymal hamartoma in the area of the 8(th) rib diagnosed in the first year of life, which was surgically removed completely. Her brother had been treated for JAOF of the right nasal sinus area diagnosed at the age of 15 months. Both lesions are extremely rare mutations of the local tissue, which occur typically in early childhood and continue benignly after surgical resection, but such a familial occurrence in siblings has not yet been reported. Furthermore, according to the histologic findings, the JAOF also could be seen as a hamartomatous lesion.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
5/23. mycosis fungoides of the larynx: case report and review of the literature.mycosis fungoides is a rare cutaneous lymphoma. Dissemination to extra-cutaneous sites occurs at advanced stages of disease. Laryngeal manifestations of mycosis fungoides have been reported in only 13 cases in the available literature. We present a further calla of mycosis fungoides of the larynx at the terminal stage of disease with an additional manifestation in the left maxillary sinus and review the cases published to date. To our knowledge this is the first reported case of mycosis fungoides with laryngeal and paranasal sinus manifestation. Concluding from the present case and from literature therapy should be palliative to improve quality of life.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
6/23. Arteriovenous malformation of the maxillary sinus and mandible: a case report.Vascular tumors are rarely encountered in the paranasal sinuses. When they do arise there, they can be life-threatening because of the risk of bleeding. Embolization alone and in combination with surgical resection has been the mainstay of treatment. We report the case of a prepubertal girl who experienced two recurrences of arteriovenous malformation, one in the maxillary sinus and the other in the mandible. To our knowledge, this is the first report in the literature of recurrences arising in these two locations.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
7/23. Osteogenic sarcoma after orbital radiation rhabdomyosarcoma.PURPOSE: We describe the occurrence of maxillary and orbital osteogenic sarcoma in a child after treatment of contralateral orbital rhabdomyosarcoma with external beam radiation and chemotherapy. DESIGN: Interventional case report. INTERVENTION: Treatment of a maxillary and orbital rhabdomyosarcoma with surgical resection, systemic chemotherapy, and local radiation. MAIN OUTCOME MEASURES: Occurrence and histology of secondary malignancy after orbital radiation. RESULTS: An eleven year-old male presented for evaluation of left facial swelling, occurring ten years after successful treatment of a right orbital embryonal rhabdomyosarcoma with chemotherapy and 5040 cGY of external beam radiation. Computerized tomography demonstrated a mass involving the left maxillary sinus and orbital floor. biopsy demonstrated osteogenic sarcoma. Despite attempted total excision with radical maxillectomy, resection margins were found to have microscopic extension of the tumor. Postoperatively he was treated with systemic chemotherapy and local radiation. Eight months postoperatively he remains alive despite local progression. CONCLUSIONS: Osteogenic sarcoma can occur as a secondary malignancy years after the successful treatment of orbital rhabdomyosarcoma with external beam radiation and chemotherapy. After orbital radiation, subjects should undergo routine lifelong examinations.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
8/23. Bilateral rhegmatogenous retinal detachment after external-beam radiotherapy: just a coincidence?PURPOSE: To report an unusual case of almost simultaneous bilateral rhegmatogenous retinal detachment in the context of external-beam radiotherapy for a tumor at a non-ocular target site and in the absence of pre-existing ocular pathology. methods: Observational case report with review of corresponding literature. RESULTS: A 63-year-old man was referred for bilateral retinal detachment which was associated with many horseshoe tears and proliferative vitreoretinopathy. He had undergone surgery for a carcinoma of the left maxillary sinus 4 months prior to the presentation and had then received external-beam radiotherapy for 3 months. There was no familial history of retinal detachment and/or eye trauma in this hyperopic patient with clear native lenses. No chorioretinal pathology was apparent that could have predisposed the retinas to tearing. CONCLUSIONS: Simultaneous bilateral retinal detachment is exceptional, especially in a patient with no risk factors. The effect of radiotherapy on the vitreoretinal interface is discussed in the light of existing data and may have been responsible for our patient's retinal detachment.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
9/23. Extramedullary plasmacytoma of the maxillary sinus.Extramedullary plasmacytomas (EMPs) are localized plasma cell neoplasms that occur within the soft tissues; by definition they cannot occur within bone. They account for 1-2% of all plasma cell growths and have a great predilection for the upper respiratory tract, without specific manifestations. Males are more frequently affected during the fifth and sixth decades of life. At initial presentation, multiple myeloma should be excluded. We report herein the case of a 63-year-old man with an EMP arising in the right maxillary sinus who was referred for surgical excision and postoperative radiotherapy and briefly review the clinical implications and management of this pathology.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
10/23. Complex odontoma of unusual size involving the maxillary sinus: report of a case and review of CT and histopathologic features.An unusually large complex odontoma of the maxilla, occupying the entire maxillary sinus with expansion into the floor of the orbit and left nasal fossa, is reported. Although occurrences of complex odontomas are not considered rare, odontomas attaining extremely large sizes, especially involving the entire maxillary sinus with extension to the orbital floor and nasal fossae, are indeed, rare. In this article, the literature is reviewed to identify the common clinical, radiographic, and histologic characteristics of such lesions, and the outcome of treatment is discussed. Complex odontomas occasionally have significant growth potential, especially in the first two decades of life. Early recognition and consideration for surgical excision are key to successful management of this common odontogenic lesion. When odontomas extend beyond the alveolar process into the fascial planes, nasal fossae, paranasal sinuses, and orbits, computed tomography can readily demonstrate the extent and boundaries of the lesion.- - - - - - - - - - ranking = 0.5keywords = life (Clic here for more details about this article) |
