Dermoid nasal cysts (congenital nasal median heterotopias) are a rare congenital pathology in children. OBJECTIVE: Yo consider the clinical picture, methods of radiation diagnosis and to study the surgical results of a dermoid cyst of the nose according to the literature. MATERIALS AND METHODS: A retrospective review of medical histories with the diagnosis of "Dermoid cyst of the back of the nose and nasal cavity, epidermal cyst of the back of the nose, glioma, encephalocele" was conducted from 2017 to 2022 in the Pediatric Otorhinolaryngological Department of the National Medical Research Center for Otorhinolaryngology of the Federal Medical-Biological Agency of Russia. The case histories were analyzed by the nature of the lesion, the imaging techniques performed, the course of the operation and the results obtained. MATERIAL AND METHODS: A total of 16 medical histories were analyzed, the average age was 4.5 years (range 10 months - 15 years), over the past 5 years with a diagnosis of "Dermoid cyst of the nasal dorsum and nasal cavity, glioma, epidermal cyst of the nasal dorsum, encephalocele". All patients underwent magnetic resonance imaging (MRI) in the preoperative period, 14 patients also underwent computed tomography (CT). RESULT: Of these, 7 had a confirmed dermoid cyst with a fistula, 3 patients without a fistula, 3 patients had glioma, and 1 had encephalocele, 2 patients had an epidermoid cyst. A fistulous opening of the dermoid cyst of the nasal dorsum and nasal cavity was observed in the upper third of the nasal dorsum in 3 children, in the middle third in 2 patients and in the lower third in 2 children. The article presents a scheme for the characteristics of the lesion and the tactics of surgical treatment in comparison with the data of foreign authors. Intraoperatively, intracranial spread occurred in 6 patients. Various surgical approaches for intracranial proliferation and a corresponding literature review are also presented. Catamnestic follow-up ranged from 1 to 5 years (on average, 3.5 years), no relapses or postoperative complications were noted. CONCLUSION: Nasal median heterotopias are a rare congenital anomaly. Preoperative preparation should include CT and MRI to assess the lesion and exclude intracranial spread. The surgical approach depended directly on the localization of heterotopia and its spread. All patients had a good cosmetic result after the surgical treatment performed by us according to the author's method.

Deep learning model for differentiating nasal cavity masses based on nasal endoscopy images.

BACKGROUND: Nasal polyps and inverted papillomas often look similar. Clinically, it is difficult to distinguish the masses by endoscopic examination. Therefore, in this study, we aimed to develop a deep learning algorithm for computer-aided diagnosis of nasal endoscopic images, which may provide a more accurate clinical diagnosis before pathologic confirmation of the nasal masses. METHODS: By performing deep learning of nasal endoscope images, we evaluated our computer-aided diagnosis system's assessment ability for nasal polyps and inverted papilloma and the feasibility of their clinical application. We used curriculum learning pre-trained with patches of nasal endoscopic images and full-sized images. The proposed model's performance for classifying nasal polyps, inverted papilloma, and normal tissue was analyzed using five-fold cross-validation. RESULTS: The normal scores for our best-performing network were 0.9520 for recall, 0.7900 for precision, 0.8648 for F1-score, 0.97 for the area under the curve, and 0.8273 for accuracy. For nasal polyps, the best performance was 0.8162, 0.8496, 0.8409, 0.89, and 0.8273, respectively, for recall, precision, F1-score, area under the curve, and accuracy. Finally, for inverted papilloma, the best performance was obtained for recall, precision, F1-score, area under the curve, and accuracy values of 0.5172, 0.8125, 0.6122, 0.83, and 0.8273, respectively. CONCLUSION: Although there were some misclassifications, the results of gradient-weighted class activation mapping were generally consistent with the areas under the curve determined by otolaryngologists. These results suggest that the convolutional neural network is highly reliable in resolving lesion locations in nasal endoscopic images.

Diagnostic accuracy of clinical visual assessment using endoscopic images for nasal cavity mass lesions.

Objectives: Discrimination of nasal cavity lesions using nasal endoscopy is challenging because of the differences in clinical manifestations and treatment strategies. We aimed to investigate the diagnostic accuracy of clinical visual assessment (CVA) of nasal cavity masses using endoscopic images and determine whether there is a difference according to pathologic class and the examiners' experience. Methods: We collected pathologically confirmed endoscopic images of normal findings, nasal polyp (NP), benign tumor, and malignant tumor (each class contained 100 images) randomly selected. Eighteen otolaryngologists, including six junior residents, six senior residents, and six board-certified rhinologists classified the test set images into four classes of lesions by CVA. Diagnostic performance according to the pathologic class and the examiner's experience level was evaluated based on overall accuracy, F1-score, confusion matrix, and area under the receiver operating characteristic curve (AUC). Results: Diagnostic performance was significantly different according to the pathological class of nasal cavity mass lesions with the overall accuracy reported high in the order of normal, NP, benign tumor, and malignant tumor (0.926 ± 0.100; 0.819 ± 0.135; 0.580 ± 0.112; 0.478 ± 0.187, respectively), F1 score (0.937 ± 0.076; 0.730 ± 0.093; 0.549 ± 0.080; 0.554 ± 0.146, respectively) and AUC value (0.96 ± 0.06; 0.84 ± 0.07; 0.70 ± 0.05; 0.71 ± 0.08, respectively). The expert rhinologist group achieved higher overall accuracy than the resident group (0.756 ± 0.157 vs. 0.680 ± 0.239, p < .05). Conclusion: CVA for nasal cavity mass was highly dependent on the pathologic class and examiner's experience. The overall accuracy was reliably high for normal findings, but low in classifying benign and malignant tumors. Differential diagnosis of lesions solely based on nasal endoscopic evaluation is challenging. Therefore, clinicians should consider further clinical evaluation for suspicious cases.

Evaluation of narrow-band imaging in the diagnosis of sinonasal inverted papilloma.

KEY POINTS: Narrow-band imaging (NBI) can be used to differentiate benign sinonasal lesions NBI can be used in the preoperative identification of sinonasal inverted papilloma Future studies can focus on NBI for recurrent inverted papilloma and surgical margin guidance.

Computed Tomography Imaging Patterns of Sinonasal Inverted Papillomas: Comparison of Primary and Recurrent Disease.

OBJECTIVE: To analyze clinical and radiographic features that may impact the rate of focal hyperostosis (FH) on computed tomography (CT) for primary and recurrent sinonasal inverted papillomas (IPs) as well as highlight factors that may affect concordance between FH and IP true attachment point (TAP). METHODS: All IPs resected between 2006 and 2022 were retrospectively reviewed. CTs were read by a neuroradiologist blinded to operative details. IP with malignancy was excluded. Operative reports and long-term follow-up data were evaluated. RESULTS: Of 92 IPs, 60.1% had FH, 25% had no CT bony changes, and 20.7% were revision cases. The recurrence rate for rhinologists was 10.5% overall and 7.3% for primary IPs. Primary and revision IPs had a similar rate of FH (63% vs. 52.6%; p = 0.646) and FH-TAP agreement (71.7% vs. 90%; p = 0.664). Nasal cavity IPs, especially with septal attachment, were more likely to lack bony changes on CT (57.1%) compared to other subsites (p = 0.018). Recurrent tumors were 16 mm larger on average (55 mm vs. 39 mm; p = 0.008). FH (75.0% vs. 60.9%; p = 0.295), FH-TAP concordance (91.7% vs. 74.4%; p = 0.094), and secondary IP (18.8% vs. 20.3%; p = 0.889) rates were similar between recurrent and nonrecurrent tumors. CONCLUSION: Primary and revision IPs have a similar rate of FH and FH-TAP agreement. Nasal cavity IPs are less likely to exhibit bony CT changes. Lower recurrence was associated with smaller size and fellowship training but not multiple TAPs, revision, FH absence, or FH-TAP discordance. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1591-1596, 2024.

La linfogammagrafía in vivo de los tumores del seno nasal identifica el ganglio retrofaríngeo y el nivel I como ganglios centinela predominantes / In-vivo lymphoscintigraphy of sinonasal tumors identifies retropharyngeal node and level I as predominant sentinel nodes

Objetivo Evaluar mediante linfogammagrafía in vivo y con detección SPECT/TC los patrones de drenaje linfático de los tumores del seno paranasal (SPN). Confirmar o rebatir la creencia de que el ganglio linfático retrofaríngeo (GLRF) se erige en el ganglio de drenaje índice para dichos tumores. Métodos Estudio de cohorte prospectivo realizado en pacientes con tumores del SPN no tratados previamente y sin evidencia clínico-radiológica de metástasis a nivel ganglionar. La linfogammagrafía se realizó mediante la inyección peritumoral de sulfuro coloidal marcado con [99m]TcO4 y asistida por endoscopia nasal. Las inyecciones se clasificaron como anteriores o posteriores en función de una línea vertical que pasaba por el orificio del seno maxilar. Resultados Se incluyeron 17 pacientes. La linfogammagrafía identificó satisfactoriamente 17 ganglios centinelas en 15 pacientes, y no pudo evidenciarlo (fracaso de la linfogammagrafía) en 2 pacientes. Se observó que los lugares predominantes de drenaje del ganglio centinela fueron el GLRF (n=8; 47%) y el nivel I (n=7; 42%). Se identificó drenaje ocasional en el ganglio periparotídeo (n=1) y en el nivel II (n=1). Se observó drenaje linfático contralateral en 2 pacientes (en el nivel I y GLRF, respectivamente). Las inyecciones anteriores drenaron predominantemente hacia el nivel I (6/8) y a GLRF (2/8), mientras que las inyecciones posteriores drenaron predominantemente a GLRF (6/7). El riesgo relativo de que el GLRF fuera identificado como ganglio centinela fue significativamente mayor en las inyecciones administradas posteriormente respecto a las administradas anteriormente (RR: 3,43; IC 95%: 1,0-11,8; p=0,05). Conclusión El GLRF es considerado un ganglio de drenaje frecuente asociado a los tumores del seno nasal, y merece su atención rutinaria en todos los casos de tumor del seno nasal (AU)

Objective To evaluate by in vivo lymphoscintigraphy and SPECT-CT imaging, the lymphatic drainage patterns of para-nasal sinus (PNS) tumours. To confirm or refute the belief of the retropharyngeal lymph node (RPLN) being the significant draining lymph node for such tumours. Methods Prospective cohort study conducted on previously untreated PNS tumours with no clinico-radiological evidence of lymph node metastasis. Lymphoscintigraphy undertaken by nasal endoscopic assisted peritumoral injection of 99mTc sulphur colloid. Injections were classified as anterior or posterior as per a vertical line along the maxillary sinus ostium. Results Seventeen patients were included. Lymphoscintigraphy successfully identified 17 sentinel nodes in 15 patients and was unsuccessful (lymphoscintigraphy failure) in 2 patients. Predominant sites of sentinel lymphatic drainage were noted to be the RPLN (n=8; 47%) and level I (n=7; 42%). Occasional drainage was identified at the peri-parotid node (n=1) and at level II (n=1). Contralateral drainage was noted in 2 patients (level I-1 and RPLN-1). Anterior injections drained predominantly to level I (6/8) and RPLN (2/8), while posterior injections drained predominantly to the RPLN (6/7). The relative risk of RPLN being identified as the sentinel node was significantly higher for posteriorly placed injections than for anteriorly placed injections (RR: 3.43; 95% CI: 1.0-11.8; P=.05). Conclusion The RPLN is noted as a frequent draining node for sino-nasal tumours and merits routine attention in all sino-nasal tumours. The radio-colloid SPECT-CT technique described here offers an excellent in vivo technique to further explore and validate the lymphatic drainage pathways of these tumours (AU)

Treatment and Management of a Sinonasal Hemangiopericytoma.

Sinonasal Hemangiopericytoma (HPC) is a rare vascular tumor originated from Zimmermann's pericyte with not well valuable course. The diagnosis needs a careful ENT endoscopic examination, radiological study and histopathological analysis with immunohistochemistry for confirmation of diagnosis. We describe a case of a male patient, 67 years old, with history of repeated monolateral right epistaxis. Endoscopic and radiological examination showed an ethmoid-sphenoidal lesion which occupied the entire nasal fossa extending towards the choana, with blood supply coming from the posterior ethmoidal artery. The patient performed an extemporaneous biopsy with subsequent en-bloc removal in operating room, without prior embolization, with the Centripetal Endoscopic Sinus Surgery technique (CESS). The histopathologic analysis led to the diagnosis of sinus HPC. The patient performed close endoscopic follow-ups every 2 months, without performing radio or chemotherapy, and with no evidence of recurrence after 3 years of follow-up. Analyzing the recent literature, a more indolent course with low recurrence rates after total endoscopic surgery remotion was described. Preoperative embolization can be useful in determinate cases, but cause to different complications, it should not be ordinarily performed.

Dynamic contrast-enhanced computed tomography in dogs with nasal tumors.

BACKGROUND: Treatment of nasal tumors in dogs is associated with high morbidity and reliable prognostic factors are lacking. Dynamic contrast-enhanced computed tomography (DCECT) can be used to assess tumor perfusion. OBJECTIVES: To assess perfusion parameters of nasal tumors (correlating with tumor type) before and during radiotherapy (RT) and find potential correlation with survival. ANIMALS: Twenty-four client-owned dogs with nasal tumors, including 16 epithelial tumors and 8 sarcomas. METHODS: Prospective cross-sectional study. All dogs had baseline DCECT to assess fractional vascular volume (BV), blood flow (BF), and transit time (TT). Thirteen dogs had repeat DCECT after 12 Gy of megavoltage RT. Survival times were calculated. RESULTS: Median BV was 17.83 mL/100 g (range, 3.63-66.02), median BF was 122.63 mL/100 g/minute (range, 23.65-279.99), and median TT was 8.91 seconds (range, 4.57-14.23). Sarcomas had a significantly lower BF than adenocarcinomas (P = .002), carcinomas (P = .01), and other carcinomas (P = .001), and significantly lower BV than adenocarcinomas (P = .03) and other carcinomas (P = .004). Significant associations were found between epithelial tumors and sarcoma for change in tumor volume (P = .01), width (P = .004), and length (P = .02) in that epithelial tumors decreased in volume whereas sarcomas increased in volume. Perfusion parameters were not correlated with survival. CONCLUSIONS AND CLINICAL IMPORTANCE: Nasal sarcomas have lower BV and BF than nasal carcinomas, and sarcomas have a lower size reduction than carcinomas early on during RT. Baseline results and changes in perfusion parameters may not be correlated with survival.

Operative Technique and Complication Management in a Case of Giant Esthesioneuroblastoma Resected by a Combined Transcranial and Endonasal Endoscopic Approach: Technical Case Report.

BACKGROUND AND IMPORTANCE: Esthesioneuroblastoma (ENB) is a rare anterior skull base tumor derived from olfactory epithelium. There are very few operative videos in the literature demonstrating the surgical resection techniques for giant ENB because of their rarity and complexity. In this technical report, we demonstrate the microsurgical resection of a very large and complex high-grade ENB, initially deemed unresectable, through a bifrontal craniotomy and extended subfrontal approach combined with an endonasal endoscopic approach. CLINICAL PRESENTATION: A 34-year-old woman presented with headaches, nasal congestion, and bloody nasal drainage. MRI showed a large nasal cavity mass with extension into the anterior cranial fossa and bifrontal lobes. There was significant bifrontal edema causing headaches and abutting the optic nerves. Initial management with surgical resection was offered to the patient for local tumor control and to preserve her vision. A combined bifrontal craniotomy and endonasal transsphenoidal approach was used for resecting this giant tumor. After achieving gross total resection, we reconstructed the anterior skull base in layers. She developed several postoperative complications which were appropriately managed. CONCLUSION: We demonstrate the surgical resection of a giant ENB through a combined transcranial and endonasal endoscopic approach. We discuss the several postoperative complications in this complex case and the lessons learned.

Radiographic predictors of occult intracranial involvement in olfactory neuroblastoma patients.

BACKGROUND: Traditional management of olfactory neuroblastoma (ONB) includes margin-negative resection with removal of cribriform plate, dura, and olfactory bulb, regardless of intracranial disease. This approach may be overtreating certain patients. Our investigation examines risk factors associated with occult intracranial disease to optimize therapeutic outcomes. METHODS: This retrospective, multi-institutional cohort study examined clinical covariates associated with occult intracranial involvement. Patient demographics, staging, Hyam's grade, and pathologic involvement of dura, olfactory bulb/tract, and brain were collected. Diagnostic imaging was reviewed. Positive and negative predictive value (NPV) were estimated along with effect size estimates. Cox hazard regression examined associations with overall survival (OS) and disease-free survival (DFS). RESULTS: A total of 224 subjects with new diagnoses of ONB (2005-2021) were identified. Skull base bone involvement on computed tomography (CT) had the highest NPV for pathologic dura (88.0%), olfactory bulb (88%), and brain involvement (97.3%). Hyam's grade category was significantly associated with dural involvement (φC  = 0.26; 95% confidence interval [CI]: 0.16, 0.42). Subjects without radiologic skull base involvement (n = 66) had pathologic positivity of 12.1%. Within this subgroup, Hyam's grade was clinically significant for dural positivity (φ = 0.34; 95% CI: -0.12, 0.71) with 28.6% involvement in high grade tumors. Neither clinical nor pathologic positivity of intracranial structures were associated with significantly different OS or DFS. CONCLUSIONS: Both CT and magnetic resonance imaging (MRI) had reasonably good NPV for involvement of dura and olfactory bulb. Higher Hyam's grade was associated with dural involvement. Patients with low-grade tumors not involving the skull base may be suitable for avoiding skull base resection; however, further investigation is warranted.

Magnetic resonance imaging findings in patients with idiopathic olfactory dysfunction and normal findings on nasoendoscopy.

OBJECTIVE: In presentations of anosmia or dysosmia, magnetic resonance imaging may be required to screen for intracranial pathology such as olfactory neuroblastomas and other intracranial masses impacting on the olfactory pathway. This study aimed to establish positive magnetic resonance imaging findings of anosmia or dysosmia for scans performed before the coronavirus disease 2019 pandemic. METHODS: The study examined the outcome of patients who presented with isolated olfactory dysfunction and who underwent magnetic resonance imaging between 2015 and 2019. RESULTS: Of the 131 patients, 41 (31.3 per cent) had normal scan findings, 50 (38.2 per cent) had insignificant paranasal mucosal disease and 6 (4.6 per cent) had mucosal thickening significant enough to require additional intervention. These interventions included repeat nasoendoscopy or commencement of intranasal or oral steroids. No patients had olfactory neuroblastoma. CONCLUSION: Only 4.6 per cent of the magnetic resonance imaging scans revealed abnormal findings related to anosmia or dysosmia, and none required ENT surgical intervention. None of the magnetic resonance imaging scans identified an olfactory neuroblastoma or intracranial masses impacting on the olfactory pathway.

A highly specific recurrent pleomorphic adenoma of the nasal septum.

A 90-year-old woman presented with the sudden onset of visual loss. She previously underwent surgery to treat a right septal pleomorphic adenoma (PA) at 77 years old. She initially presented to our hospital with severe nasal obstruction at 83 years old. A large tumor occupied the bilateral nasal cavities and, thus, surgery was performed using midfacial degloving and an endoscopic endonasal combined approach. A 60×45×43 mm tumor was completely removed; however, a small area of the tumor capsule was damaged. Six years after surgery, PA recurred in the posterior midline portion of the nasal cavity. Imaging examinations revealed a 48×42×45 mm mass, which compressed the bilateral optic canal, thereby causing severe visual loss. The recurrent tumor was endoscopically removed, and vision recovered after surgery. The lack of malignant transformation was pathologically confirmed throughout this period. The present case had several highly specific features: she was very elderly, the tumor was very large, and visual dysfunction was caused by nasal PA. We described surgical procedures in detail and considered the specific findings of the present case. En bloc resection with a sufficient margin was considered to be important in the present case because recurrence may be caused by incomplete excision.

Nasal Septal Angiofibroma.

Juvenile nasopharyngeal angiofibroma is a benign vascular tumor seen predominantly in adolescent males in the second decade of life. Extranasopharyngeal angiofibroma includes vascular fibrous masses that occur outside the nasopharynx. The diagnosis of an angiofibroma is based on the clinical presentation and imaging, with biopsies being avoided to avoid excessive bleeding. Computed tomography scan is considered sufficient for the diagnosis of extranasopharyngeal angiofibroma as it clearly delineates and identifies the tumor.

Narrow-band imaging for detecting nasal lymphoma.

INTRODUCTION: Narrow-band imaging (NBI) is an advanced endoscopic technique that enhances the mucosal neovascularization. The utilization of narrow-band imaging on the detection of nasal lymphomas is not well-established. AIM: To present a clinical case whose nasal lymphoma was detected with the aid of NBI. CASE REPORT: A 91-year-old male presented to the ear, nose, and throat clinic with right persisting nasal obstruction for 4 months. NBI revealed a well demarcated lesion with an elongated vessel on the surface of the right inferior nasal turbinate. Histopathologic analysis of tissue specimen proved to be extranodal NK/T-cell lymphoma, nasal type. CONCLUSIONS: NBI is useful for the detection of nasal lymphomas. NBI may be a valuable screening tool for nasal lymphomas as it is non-invasive and affordable.

Aberrant Hypermetabolism of Nasal Leiomyoma Mimicking Malignancy on 18 F-FDG PET/CT.

ABSTRACT: Leiomyomas are benign tumors that commonly arise from the uterus. They rarely occur in the nasal cavity. Leiomyomas and leiomyosarcomas are clinically similar and may be difficult to distinguish preoperatively. Although PET has been reported to be useful for evaluating uterine smooth muscle tumors, the use of PET for evaluating sinonasal leiomyoma has not yet been reported. Here, we describe the images of a patient with leiomyoma of the nasal septum in whom intense FDG uptake was noted on PET/CT.

Hemicraniectomía endonasal por estesioneuroblastoma: informe de un caso / Endonasal hemicraniectomy by esthesioneuroblastoma: report of a case

El estesioneuroblastoma es una neoplasia maligna que se origina del epitelio olfatorio. El tratamiento se establece de acuerdo con su extensión y el grado histológico de atipia y puede incluir cirugía, cirugía más radioterapia o más radioquimioterapia. Se han utilizado diferentes abordajes quirúrgicos que incluyeron incisiones faciales y craneotomía pero, con la mayor experiencia adquirida en cirugía endoscópica de senos paranasales y el trabajo en equipo con el neurocirujano, se han desarrollado técnicas endonasales que posibilitan realizar resecciones oncológicas en pacientes seleccionados, con menos morbilidad, internación breve y sin comprometer el control local de la enfermedad. Describimos el caso clínico de una paciente con un estesioneuroblastoma con invasión intracraneal, que fue tratada con éxito mediante una hemicraniectomía endonasal preservando el bulbo olfatorio contralateral. (AU)

Esthesioneuroblastoma is a malignant neoplasm that originates from the olfactory epithelium. Treatment is established according to its extension and the histological degree of atypia and may include surgery, surgery more radiotherapy or more chemoradiation therapy. Different surgical approaches have been used, including facial incisions and craniotomy, but with the greater experience acquired with endoscopic sinus surgery and teamwork with the neurosurgeon, endonasal techniques have been developed that make it possible to perform oncological resections in selected patients, with less morbidity, brief hospitalization and without compromising local control of the disease. We describe the clinical case of a patient with an esthesioneuroblastoma with intracranial invasion who was successfully treated by endonasal hemicraniectomy preserving the contralateral olfactory bulb.

Angiosarcoma de cavidad nasal: reporte de caso y revisión de literatura / Nasal cavity angiosarcoma: case report and literature review

Los tumores malignos de cavidad nasal y cavidades paranasales son poco frecuentes y sus síntomas de presentación suelen ser unilaterales e inespecíficos; éstos incluyen: epistaxis, rinorrea y obstrucción nasal. Encontramos una amplia variedad histológica de tumores, entre ellos tenemos el angiosarcoma nasal, que es considerado una rareza y el diagnóstico definitivo lo da la confirmación anatomopatológica complementado con estudios inmunohistoquímicos. Su modalidad de tratamiento incluye múltiples opciones, pero la cirugía radical temprana con márgenes negativos asociado a radioterapia adyuvante, ofrece el mejor pronóstico. Se presenta a un paciente adulto masculino con un angiosarcoma nasal izquierdo que fue detectado de forma precoz y se manejó con cirugía radical y radioterapia.

Malignant tumors of the nasal cavity and paranasal cavities are rare, while presenting symptoms are usually unilateral and nonspecific like, epistaxis, rhinorrhea, and nasal obstruction. There are many histological varieties of tumors, among them we have nasal angiosarcoma, which is considered a rarity pathology. The definitive diagnosis is given by biopsy confirmation complemented with immunohistochemical studies. Its treatment modality includes multiple options, but early radical surgery with negative margins associated with adjuvant radiotherapy offers the best prognosis. We present a male adult patient with a left nasal angiosarcoma that was detected early and managed with radical surgery and radiotherapy.
