Objective:To investigate the anatomic origin of juvenile nasopharyngeal angiofibroma（JNA） through radiologic analysis of tumor invasion patterns, providing insights into tumor etiology and surgical recurrence prevention. Methods:This retrospective cohort study included primary JNA cases at the Department of Otorhinolaryngology, Eye and ENT Hospital of Fudan University from March 2015 to September 2024. All patients underwent preoperative high-resolution CT（HRCT） scans, and some underwent enhanced magnetic resonance imaging. The study retrospectively analyzed the patients' imaging data to examine tumor invasion into the pterygopalatine fossa and the vidian canal. These sites were categorized into non-invaded, partially invaded, and completely invaded for the pterygopalatine fossa and the vidian canal. The study analyzed the proportions of invasion at these sites to further speculate on the origin of JNA. Results:A total of 105 JNA patients were included in the study. Among them, 100% of the patients had complete tumor invasion in the pterygopalatine fossa. For the vidian canal, the proportions of complete invasion, partial invasion, and non-invasion were 54.3%, 27.6%, and 18.1%, respectively. As the staging of JNA tumors increased, the proportion of vidian canal invasion also increased. Conclusion:Our evidence suggests that the pterygopalatine fossa, rather than the vidian canal, might be the likely origin of JNA, which is enlightening for the study of the etiological mechanisms of JNA.

Tuberous sclerosis complex (TSC) is a rare, autosomal dominant multisystem disorder affecting the brain, heart, kidneys, lungs, and skin leading to significant morbidity and mortality. We report a case of TSC and highlight the need for prompt diagnosis and proper surveillance to minimize life‑threatening complications. A 20‑year‑old female presented with facial and ungual papulonodular lesions 4 years after being diagnosed with epilepsy at the age of eight. No family history of genetic diseases was reported. Eight years later, the patient developed recurrent cough, shortness of breath, and blurring of vision. Biopsy of facial and digital nodule showed angiofibroma and ungual fibroma (Koenen tumor), respectively. Chest computed tomography scan revealed extensive cystic lesions diffusely scattered throughout the entire lung parenchyma suggestive of lymphangioleiomyomatosis. Cranial MRI revealed cortical and subependymal tubers, compatible with TSC. The patient had multidisciplinary management. However, her symptoms progressed, and she eventually succumbed to death. Cutaneous lesions such as facial angiofibromas and ungual fibromas along with multisystemic manifestations should alarm the clinician to TSC. Given its highly variable expressivity, awareness of different TSC‑associated signs and symptoms is essential for prompt diagnosis, proper treatment, disease monitoring, and early recognition of TSC complications.

Objective:To investigate the clinical effect of plasma resection of juvenile nasopharyngeal angiofibroma（JNA） under nasal endoscope. Methods:The clinical data of 12 cases with JNA treated in the Department of Otorhinolaryngology and head and neck surgery of the 940th Hospital from 2015.01 to 2020.01 were analyzed retrospectively. All of them were young males. Imaging examination, digital subtraction angiography（DSA） and selective blood supply artery embolization were performed before operation, and then plasma was used to remove the tumor under nasal endoscope. The patients were followed up for at least 30 months. During the follow-up, the nasal cavity was observed under nasal endoscope and the tumor recurrence was observed by imaging examination. Results:In 12 cases, the vision was clear, the amount of bleeding was less, the operation time was within 2 h, and the postoperative recovery time was short. 12 cases were followed up and no tumor recurrence was found by nasal endoscopy and imaging examination. Conclusion:Selective external carotid artery embolization before operation and plasma resection of JNA under nasal endoscope during operation is a safe and effective treatment, which can effectively improve the cure rate and reduce the recurrence rate.

Objective:To investigate the surgical approach for the resection of juvenile nasopharyngeal angiofibroma（JNA） under nasal endoscopy. Methods:The clinical data of 87 patients undergoing endoscopic resection of nasopharyngeal fibroangioma were retrospectively analyzed. We classified JNA according to tumor site, size, invasion scope and anatomic position relationship between tumor and midline of pupil. Three endoscopic surgical approaches were selected according to the classification, and the postoperative symptoms, complications and recurrence were investigated and analyzed. Results:The tumor resection rate of 87 cases by nasal endoscopic surgery was 100%. Thirty-five cases were approached through the middle nasal passage（small tumors located in the nasal sinuses and pterygopalatine fossa）, forty-five cases were approached through the lateral wall of the nasal cavity（tumor invaded the pterygopalatine fossa but did not exceed the midline of the pupil） , and seven cases were approached via the lateral wall of nasal cavity + ipsilateral anterior wall of maxillary sinus（tumor invaded the infratemporal fossa beyond the midline of pupil or invaded the cavernous sinus and the middle cranial fossa epidural）, Postoperative patients with nasal congestion, nasal bleeding, headache, dizziness, vision loss and other symptoms showed varying degrees of improvement. No surgical death or intracranial infection occurred. The postoperative follow-up was 6-78 months, and the recurrence rate was 3.44%. Conclusion:Endoscopic resection of nasopharyngeal fibroangioma is the main treatment method for JNA. Selecting suitable endoscopic approach to resect JNA, To maximize the advantage of nasal endoscopic equipment according to the inherent anatomical space of the human nasal cavity, In order to achieve the purpose of JNA resection, reduce intraoperative and postoperative complications, reduce the recurrence rate and improve the prognosis.

Angiofibromas are highly vascular, locally aggressive but histologically benign tumors. A 40-year-old woman complaint of pedunculated mass in the right gingiva of the posterior region since 7 months earlier. Surgical excisional biopsy under general anesthesia was performed. Histopathological examination showed an angiofibroma. Angiofibromas are localized in the superficial soft tissue and the gingiva could have a similar clinical appearance as an epulis. Definitive diagnosis was determined through histopathological analysis.

The characteristics of extra-nasopharyngeal angiofibromas tend to be different from angiofibromas of the nasopharynx according to patient gender, patient age, prevalence, affected site, pathogenesis, and clinical and epidemiological features. We report a case of an extra-nasopharyngeal angiofibroma in a 28-year-old man referred to the ENT Clinic for right-sided epistaxis, airflow impairment and nasal swelling. The right nostril was completely occluded works by a reddish-yellow mass that bled easily. The computed tomography scan revealed an “inhomogeneous solid lesion in the nasal fossa”. With the patient under general anesthesia, the formation in the anterior portion of the right side of the nasal septum was removed up to its vascular base. Although electrical cauterization efficiently controlled the bleeding, we abraded the sub-perichondral area to prevent further bleeding as well as recurrence. The histological exam report confirmed the diagnosis of angiofibroma. As in our case, epistaxis is commonly the presenting sign of angiofibroma. Yet its onset was peculiar, given that the bleeding started with a low impact trauma. The nasal swelling was also a relevant feature as well as the breathing impairment. Although uncommon, nasal septal angiofibromas should considered in patients with epistaxis.

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disorder with an incidence of approximately 1 in 5,000 to 10,000 live births. TSC has various clinical manifestations such as multiple hamartomas in systemic organs, including the skin. Angiofibromas are the most common skin lesions in patients with TSC. Although benign, angiofibromas develop in childhood and puberty, and can be psychosocially disfiguring for patients. Skin lesions in TSC, specifically angiofibromas, have no significant risk of malignant transformation after puberty; thus, they require no treatment if not prominent. However, the presentation of TSC is important owing to its impact on patient cosmesis. Surgical treatment and laser therapy are the mainstream treatments for angiofibromas. Although the evidence is limited, topical mammalian target of rapamycin inhibitors such as sirolimus (rapamycin) are effective in facial angiofibroma treatment. We describe an adult patient with an angiofibroma who had an excellent response to treatment with topical rapamycin after a single session of carbon dioxide (CO₂) laser ablation. The patient showed no sign of relapse or recurring lesions for a year. CO₂ laser ablation may serve as a new paradigm of treatment for angiofibromas in TSC. Since the selection of laser devices can be limited for some institutions, we suggest a rather basic but highly effective approach for angiofibroma treatment that can be generally applied with the classic CO₂ device.
