Frontoethmoidal Extranasopharyngeal Angiofibroma With Orbital Pyocele.

Significance StatementExtranasopharyngeal angiofibromas (ENA) are rare vascular tumors that do not conform to the clinical characteristics of typical nasopharyngeal angiofibromas. We present the management of an angiofibroma in a rare site, within the frontal sinus with a concomitant orbital pyocele, which was completely excised via an endoscopic approach. ENAs should be considered as a differential diagnosis in patients with sinonasal mass and epistaxis. Awareness of this rare entity will avoid radical surgery thus decreasing postoperative morbidity.

Sinonasal organising haematoma - a little known entity / Hematoma nasossinusal em organização - uma entidade pouco conhecida

Abstract Introduction: Sinonasal organising haematoma is a recently described, rare, benign inflammatory condition, which closely resembles malignancy in its clinical presentation. Objective: To describe the clinical features of organising haematoma and to review the evolution of surgical options successfully used. Methods: A retrospective review of charts of all patients with a histopathological diagnosis of sinonasal organising haematoma was performed. Results: Six (60%) of the 10 patients were male with a mean age of 47.4 years. All patients had unilateral disease with recurrent epistaxis as the presenting symptom. Maxillary sinus was the most commonly involved sinus. There was no history of trauma in any of the patients. Hypertension (80%) was the most commonly associated comorbidity. Contrast-enhanced CT scan of the paranasal sinuses showed heterogeneous sinus opacification with/without bone erosion. Histopathological examination was diagnostic. Complete endoscopic excision was done in all patients resulting in resolution of the disease. Conclusion: Awareness of this relatively new clinical entity and its evaluation and treatment is important for otolaryngologists, maxillofacial surgeons and pathologists alike. Despite the clinical picture of malignancy, histopathological features of benign disease can safely dispel such a diagnosis.

Resumo Introdução: Hematoma nasossinusal em organização é uma condição inflamatória benigna rara, recentemente descrita, que se assemelha a lesões malignas em sua apresentação clínica. Objetivo: Descrever as características clínicas do hematoma em organização e analisar a evolução das opções cirúrgicas usadas com sucesso. Método: Foi feita a revisão retrospectiva dos prontuários de todos os pacientes com diagnóstico histopatológico de hematoma nasossinusal em organização. Resultados: Seis (60%) dos 10 pacientes eram do sexo masculino, com média de 47,4 anos. Todos os pacientes apresentavam doença unilateral com epistaxe recorrente como sintoma de apresentação. O seio maxilar era o mais comumente afetado. Não havia histórico de trauma em qualquer dos pacientes. Hipertensão (80%) foi a comorbidade mais comumente associada. A tomografia computadorizada dos seios paranasais com contraste mostrou opacificação heterogênea do seio com/sem erosão óssea. O exame histopatológico foi diagnóstico. A excisão endoscópica completa foi feita em todos os pacientes, resultou na resolução da doença. Conclusão: A conscientização a respeito dessa entidade clínica relativamente nova e sua avaliação e tratamento são importantes para os otorrinolaringologistas, cirurgiões buco-maxilo-faciais e patologistas. Apesar do quadro clínico de malignidade, as características histopatológicas da doença benigna podem descartar com segurança esse diagnóstico.

Monophasic Synovial Sarcoma of Tongue: A Rarest of Rare Case Scenario.

Synovial sarcoma is a rare tumour of head and neck. Primary synovial sarcoma of tongue is very uncommon. Based on morphology, it can be classified as classical biphasic variant, monophasic spindle cell variant, monophasic epithelial variant and poorly differentiated variant. The authors with an index case of 74 year old lady with monophasic spindle cell synovial sarcoma of oral tongue which is one of the rarest variants (our case is the 15th case reported of synovial sarcoma of the tongue and only the 3rd case in the world which had a monophasic histopathologic pattern) studied the morphology and described the disease entity in detail. She was treated with wide local excision of sarcoma followed by adjuvant radiotherapy.

Association between vascular supply, stage and tumour size of juvenile nasopharyngeal angiofibroma.

Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumour seen in adolescent males. To study the vascular pattern of these tumours, we retrospectively reviewed the records of patients with JNA who underwent preoperative angiography. Most (82.2 %) of the 45 patients assessed were Radkowski stage III with a mean size of 5.29 cm. There was a significant association between tumour stage and size (p = 0.029). Ten different vessels were seen to supply these tumours. All tumours had primary supply from the distal third of the ipsilateral internal maxillary artery (IMA). Accessory vessel supply was chiefly from the Vidian branch of internal carotid artery (ICA) (55.6 %). Stage III tumours were supplied by a greater number of feeding vessels than earlier stage tumours (p < 0.01). Larger tumours were more likely to have ICA supply (p = 0.04). Bilateral supply was seen in 48.7 %. However, there was no predominance of bilateral over ipsilateral IMA supply even in advanced stage tumours. One patient in our series was found to have a caroticocavernous fistula. Residual or recurrent tumours were characterized by new vasculature (100 %) and greater accessory supply from the ipsilateral ICA (85.7 %). Our study highlights the fact that surgical planning cannot be dependent on staging alone and should include preoperative assessment of tumour vasculature by angiography.
