RESUMO
INTRODUCTION: Although a COVID-19 nasopharyngeal swab is a safe procedure routinely performed by healthcare providers, it can lead to complications that can be life-threatening. We present seven cases of intractable epistaxis following a nasopharyngeal swab that required sphenopalatine artery ligation. We aim to shed light on this life-threatening condition, emphasizing the importance of recognizing and mitigating such complications. MATERIALS AND METHODS: This retrospective chart review involved cases of intractable epistaxis following a COVID-19 swab from January 2020 to June 2022. The patient's charts were reviewed for the location of the epistaxis and different intranasal and extranasal factors that could have led to it. RESULTS: Seven cases had intractable epistaxis following a nasopharyngeal COVID-19 swab. Six of the seven cases had a deviated nasal septum, and one case had an enlarged inferior turbinate. All patients had bleeding from the ipsilateral nasal structural abnormality. All patients underwent successful sphenopalatine artery ligation. CONCLUSION: Our study highlights the significance of recognizing the potential risk of intractable epistaxis post-COVID-19 swabs and emphasizes the importance of comprehensive training programs to ensure the safe and effective execution of nasopharyngeal swab procedures.
RESUMO
Multiple anatomical variations in the nasal cavity are well-described in the literature. We describe a rare case of pneumatization of the frontal sinus in the nasal septum that we term "Septo-Frontal Cell". To the best of our knowledge, this pattern of nasal septum pneumatization has not been described in the literature before. We have discussed the clinical and radiological findings and management of this patient.
RESUMO
BACKGROUND Extranodal lymphoma of the paranasal sinuses is a rare clinical entity seen in only 5-8% of extranodal lymphomas of the head and neck. Nasal natural killer/T cell lymphoma (Nasal NKTCL), which is a subtype of peripheral T cell lymphoma, constitutes about 1.4% of all lymphomas. NKTCL is usually diagnosed at a late stage because it presents with nonspecific symptoms in the early stages. CASE REPORT We report the case of a 25-year-old male patient who presented with periorbital swelling treated as fungal sinusitis but proven to have NKTCL. We review the literature and discuss the clinical manifestations of the disease, its relation to EBV virus, the histological and radiological characteristics, the prognostic indicators, and treatment options. This case report shows physicians that NKTCL lymphoma can present as periorbital cellulitis, although few similar cases are found in the literature. CONCLUSIONS NKTCL is a destructive midline tumor that should be kept in mind as a differential diagnosis of paranasal sinus lesions to help in early diagnosis, which can improve the prognosis.
