  • 文章类型: Case Reports
    一种罕见的局部侵袭性血管肿瘤,青少年鼻咽血管纤维瘤(JNA)主要影响男性青少年。本文描述了一名14岁的男性患者,他表现为嗜睡和复发性鼻出血,这是JNA的症状。CT和MRI扫描证实血管肿块具有明显的局部侵袭,起源于蝶腭孔。CT血管造影后,这揭示了肿瘤的大量血液供应,并有助于有效切除,设计了一个有针对性的手术策略。组织病理学证实了肿瘤的良性性质,手术成功,患者顺利康复。这个案例增加了关于JNA的小文献。它强调了医疗保健专业人员在管理疾病时需要了解早期识别和仔细的术前准备的要求。
    A rare and locally aggressive vascular tumor, juvenile nasopharyngeal angiofibroma (JNA) mostly affects male teenagers. This paper describes a 14-year-old male patient who presented with lethargy and recurrent nasal bleeding, which are symptoms of JNA. CT and MRI scans confirmed a vascular mass with a significant local invasion originating from the sphenopalatine foramen. After a CT angiography, which revealed the tumor\'s large blood supply and helped with efficient excision, a focused surgical strategy was designed. Histopathology verified the benign nature of the tumor, and the operation was successful and the patient had a smooth recovery. This case adds to the little literature on JNA. It highlights the need for healthcare professionals to be aware of the requirement of early identification and careful presurgical preparation in managing the illness.

    To develop a systematic method for anatomic mapping of juvenile nasopharyngeal angiofibroma (JNA) tumors to standardize communication, facilitate surgical planning, and convey prognosis.
    Retrospective cohort.
    Tertiary referral center.
    Following Institutional Review Board approval, we performed a retrospective review of radiologic and angiographic data of patients with JNA presenting to the Department of Otolaryngology-Head and Neck Surgery, Mansoura University, from 2001 to 2017. All patients underwent angiography with embolization and had >1-year follow-up. Based on frequently involved anatomic sites and factors predictive of prognosis, the NSF-COR staging system (nose/nasopharynx, sinus, fossa-cranium, orbit, residual internal carotid artery supply) was developed to explicitly convey anatomic site of involvement and presence of residual vascularity. We validated the NSF-COR staging system against other systems with Pearson chi-square test based on risk factors and clinical outcomes of blood transfusion volume, recurrence, and JNA resectability.
    Fifty-four patients met inclusion criteria, where all primary cases (100%) demonstrated nose/nasopharynx involvement, followed by sinus (85.2%), natural fossae (85.2%), intracranial (26%), and orbital involvement (16.7%). These sites, with assessment of residual internal carotid artery vascular supply, were used to develop the NSF-COR anatomically based staging system. The components COR showed significant association with clinical outcomes of blood transfusion and recurrence. Contingency coefficients between the NSF-COR staging system and available staging systems showed significant correlations (P < .05) for prognosis.
    The NSF-COR staging system conveys a communicable anatomic map of JNA tumors that integrates residual vascularity of the tumor and demonstrates strong concordance with current staging systems to assess clinical outcomes.

    OBJECTIVE: Infratemporal fossa (ITF) tumors are rare and little is known about their general epidemiology, making it sometimes difficult for clinicians, who seldom encounter them, to distinguish between benign and malignant forms on the basis of the initial clinical and radiological work-up alone. The objectives of this retrospective study were: (i) to determine the respective prevalences of the various histologic types of ITF tumor, and (ii) to assess associations between certain clinical and radiological features and malignancy.
    METHODS: A single-center observational study in a university hospital included all new consecutive cases of ITF tumor treated from January 2000 to December 2016. Histologic type, demographics, clinical presentation and imaging findings were analyzed.
    RESULTS: In total, 62 patients were included. 74% of tumors were benign (n=46) and 26% malignant. Juvenile nasopharyngeal angiofibroma, adenoid cystic carcinoma and schwannoma were the most frequent histologic types, accounting for 47%, 16% and 10% of cases, respectively. The only clinical or imaging signs significantly associated with malignancy were trismus, facial pain, facial hypoesthesia and neural invasion on magnetic resonance imaging (all P-values<0.05).
    CONCLUSIONS: This study provides general epidemiological data on ITF tumors, and identified several clinical and radiologic signs to help clinicians suspect malignancy.

    An attempt is made to analyze the molecular behavior of juvenile nasopharyngeal angiofibroma (JNA).
    Case Series METHODS: Quantification of mRNAs expression was undertaken through real-time polymerase chain reaction in JNA (9-24) samples for VEGF-A, basic fibroblast growth factor (b-FGF), platelet-derived growth factor PDGF-A, KIT proto-oncogene receptor tyrosine kinase (c-Kit), Avian myelomatosis viral oncogene homolog (c-Myc), Harvey rat sarcoma viral oncogene homolog (H-Ras), tumor suppressor gene TP53, and androgen receptor and interleukin 6 (IL-6). The β-catenin expression was evaluated by western blot in 16 samples. Nasal polyp was taken as control.
    A significantly increased (P < 0.01) expression of c-myc, VEGFA, bFGF, PDGFA, c-kit, and TP53 was seen, along with enhanced expression of β-catenin. A massive enhancement of H-Ras expression was seen for the first time. Androgen receptor expression was no different, whereas IL-6 despite showing upregulation trend was not significant.
    The enhanced expressions of various markers suggest their potential role in JNA. Although the biological significance of c-kit, c-myc, and one of the novel markers H-Ras has yet to be defined, their significant expression may have a therapeutic importance.

    This study is a retrospective analysis of 30 consecutive cases of Juvenile Nasopharyngeal Angiofibroma (JXA) operated at. Department of Head and Neck Surgery, Kidwai Memorial Institute of Oncology Bangalore, India: la tertiary referral centre) after prior emohilization by an interventional neuro-radiologisl (1996-2002). This study discusses critically the planning of surgical approach, based on anatomico-radiological factors and highlights the efficacy of preoperalive embolization in expediting total re moral of the tumor in 25 out of JO cases with advanced stage JNA.
    OBJECTIVE: To analyze the utility of pre-operatire embolisation in surgical extirpation of large JNAs; planning of the surgical approaches based on CT topography of the tumor; to study the various complications of embolisation and surgery associated with JXA & lastly to evaluate the puttern and location of recurrent tumor thus correlating with the original topography.
    METHODS: Tertiary care cancer referral centre.
    METHODS: PATIENTS ranged in age from \')- 24 years. all being males.
    METHODS: Majority of them were accessed by transfacial surgical approach(26). and in the recent past via midfacial degloving(4) within 4H hours of angioembolisation.
    RESULTS: Complete removal of the tumor was achieved in 25 out of 30 cases with advanced stage JNA.Post surgical CT scans revealed tumor residua in 5 individuals, where the tumor was documented in - the temporal fossa 12), para-cavernous sinus region (I), cavernous sinus! I) and pterygo palatine fossa (I). Only the lesion in pterygopalaline fossa was successfully re-i>xcised & this alongwith the recurrence at para-cavernous & cavernous sinus & another were treated with radiotherapy; the 2 cases in the temporal fossa are under observation. The average blood loss during the procedure was 546.60 ml.
    CONCLUSIONS: Today, advances in radiologie imaging-complemented by interventional neuro-radiological expertise in angio-embolisation have expedited complète excision with minimal morbidity and acceptable recurrence rate. This study has justified pre-operative embolisation and M currently the standard of care for advanced JXA.
