1/369. Nasal reconstruction in children: a review of 29 patients.Acquired large nasal defects are much more common in adulthood than in childhood because of the frequency of skin tumors after a certain age. However, from their experience in treating a number of children with sequelae of noma and burns, the authors have collected a series of 17 total and 12 partial nasal reconstructions in children aged 1 to 15 years. After reviewing the various methods used for recreating the lining, the support, and the skin cover in the whole series, three cases are reported in detail. A 1-year-old patient received a tempororetroauricular flap after total amputation of the nose and was observed for 17 years. Another patient, who was burned as a baby, underwent reconstruction at age 10 with a deltopectoral flap and was observed for 7 years. The third patient underwent total nose reconstruction at age 12 with an Indian forehead flap. From their experience, the authors conclude that, for psychosocial reasons, nasal reconstruction should be started early, despite possible reoperation at a later age. The best results are certainly obtained at the end of growth or at least after the age of 12. Adjacent bone or soft tissue defects further enhance the difficult challenge of restoring a satisfactory aesthetic appearance in these children.- - - - - - - - - - ranking = 1keywords = nose (Clic here for more details about this article) |
2/369. craniopharyngioma invading the nasal and paranasal spaces, and presenting as nasal obstruction.A case of craniopharyngioma invading the nasal and paranasal sinuses and presenting as nasal obstruction is reported. Imaging showed a destructive mass of the skull base with involvement of the nose and paranasal sinuses. In the excised mass mitoses were frequent and the proliferation index was high. Invasion of the nasopharynx and presentation as a nasopharyngeal mass is uncommon for a craniopharyngioma.- - - - - - - - - - ranking = 0.5keywords = nose (Clic here for more details about this article) |
3/369. Metastatic testicular teratoma of the nasal cavity: a rare cause of severe intractable epistaxis.Malignant neoplasms of the nasal cavity and paranasal sinuses are uncommon. choriocarcinoma is a highly malignant germ cell tumour occurring in the reproductive organs. Metastasis may be principally by the lymphatic route as in other germ cell tumours but choriocarcinoma is also known to spread haematogenously. We present a rare case of metastatic choriocarcinoma to the nasal cavity from testicular teratoma presenting with intractable epistaxis in a 32-year-old Caucasian male, who ultimately succumbed to this disease.- - - - - - - - - - ranking = 0.64502543748081keywords = epistaxis (Clic here for more details about this article) |
4/369. Nasal and nasal-type T/NK-cell lymphoma with cutaneous involvement.Natural killer (NK) cells are a third lymphocyte lineage, in addition to B- and T-cells, that mediate cytotoxicity without prior sensitization. NK cells also have phenotypic and genotypic characteristics; they express the NK-related antigen CD56 and T-cell markers such as CD2 and CD3 epsilon, but their T-cell receptor (TCR) locus is not rearranged. Non-Hodgkin's lymphomas are divided into B- and T-cell neoplasms and NK-cell lymphomas. We describe 2 Japanese patients with nasal and nasal-type T/NK-cell lymphoma in which the skin, nasal/nasopharyngeal region, bone marrow, and lymph node were the sites of involvement. The clinical and histopathologic findings were recorded. In addition, immunophenotyping, TCR gene rearrangement, and the existence of Epstein-Barr virus (EBV) dna by polymerase chain reaction amplification were determined. Clinically, the cutaneous eruptions were purplish, hard, multiple nodules. Histologically, angiocentric proliferation of small-to medium-sized, pleomorphic, lymphoid cells were observed. They revealed hand-mirror-shaped lymphocytes with azurophilic granules with the use of Giemsa staining by touch smear. These lymphocytes were found to be positive to immunophenotyping for CD2 (Leu5b), CD3 epsilon (DAKO), CD4 (Leu3a), and CD56 (Leu 19). No clonal rearrangement of TCR-beta, -gamma, and -delta genes and immunoglobulin gene markers were found, and no positive results of identification of EBV dna were shown. The patients underwent cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy with complete remission; however, both had recurrence of disease. Because NK-cell lymphomas express some T-cell markers, they may be mistakenly diagnosed as peripheral T-cell lymphomas if they are not investigated for the NK-cell-specific marker, CD56. Therefore the importance of immunophenotypic investigations of CD56 should be stressed. Also, the importance of clinical investigation of nasal/nasopharyngeal lymphomas should be stressed when NK-cell lymphoma is diagnosed involving the skin, because NK-cell lymphomas are often associated with the nasal and nasopharyngeal region.- - - - - - - - - - ranking = 1keywords = nose (Clic here for more details about this article) |
5/369. An unusual case of squamous cell carcinoma of the nose.A 49-year-old man presented with a tumoral lesion of the tip of the nose which had been manifest for 2 months. Within a few weeks, the tumour increased in size and became infiltrated. The biopsy showed a squamous cell carcinoma. Treatment consisted of a radical surgical excision.- - - - - - - - - - ranking = 2.5keywords = nose (Clic here for more details about this article) |
6/369. Heterotopic nasopharyngeal brain tissue associated with cleft palate.OBJECTIVE: The occurrence of extracranial brain tissue is rare. Most of the literature describes cases in which it is located around the nose and throat and has been classified as nasal glioma. Even more unusual is heterotopic brain tissue in the nasopharynx. We were able to find only 17 previously reported cases. Of these 17 cases, 6 had heterotopic brain tissue located in a cleft palate. This report comments on the identification and treatment of heterotopic brain tissue associated with cleft palate without connection to the central nervous system. Our case subject is a 10-month-old girl diagnosed with heterotopic nasophranygeal brain tissue associated with cleft palate. RESULTS: Excision and palatoplasty were performed conjunctively with excellent results. CONCLUSIONS: Simultaneous excision of heterotopic nasopharyngeal brain tissue and palatoplasty of the cleft palate is an excellent option for treatment of these cases.- - - - - - - - - - ranking = 1keywords = nose (Clic here for more details about this article) |
7/369. Primary splenic tuberculosis in a patient with nasal angiocentric lymphoma: mimicking metastatic tumor on abdominal CT.Tuberculosis may be difficult to diagnose when it presents in an uncommon extrapulmonary site. The authors report a case of splenic tuberculosis mimicking metastatic tumor on computed tomography in a 60-year-old woman who had been treated with combination chemotherapy for nasal angiocentric lymphoma. Diagnostic splenectomy revealed multiple necrotic masses in the spleen, which were consistent with caseating granulomas microscopically. diagnosis was confirmed by positive cultures in Lowenstein medium, which grew typical mycobacterium tuberculosis organisms. Following splenectomy, the patient was also treated with a triple-drug antituberculosis regimen with no recurrence of her symptoms.- - - - - - - - - - ranking = 0.5keywords = nose (Clic here for more details about this article) |
8/369. 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.- - - - - - - - - - ranking = 2.5keywords = nose (Clic here for more details about this article) |
9/369. 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.- - - - - - - - - - ranking = 0.5keywords = nose (Clic here for more details about this article) |
