Sinonasal Organised Haematoma- A Case Report and Review of Literature.

Sinonasal organised haematoma (SOH) is an uncommon, benign condition that can be locally aggressive. SOH can be mistaken for a malignant tumour but the characteristic imaging findings and histopathology facilitate the diagnosis of an organised haematoma. We report a 26 year old male patient presenting with unilateral nasal obstruction and painless epistaxis, which are the most common presenting symptoms of sinonasal tumour lesions. Based on the clinical features, age, radiological investigation, intraoperative finding, location of the lesion and histopathological examination; a diagnosis of SOH was arrived at. Surgical excision utilized the COBLATION technology and endoscopic complete removal of the nasal mass was done. Intraoperatively minimal bleeding was encountered. On histopathology, haematoma at the center and fibrosis at the periphery was noted. To our knowledge, this is the first reported case of SOH excision using Coblator. No recurrence was seen in subsequent follow ups. Although SOH can be mistaken for a malignant tumour, the characteristic imaging and histopathology findings facilitate the diagnosis of an organised haematoma.
