Nodular Fasciitis and Myxolipoma of the Larynx: A rare case report with brief literature review.

ABSTRACT

Nodular fasciitis (NF) is a peculiar, rapid-growing soft tissue lesion, typically appearing in subcutaneous tissue. Approximately 20% of NF occurs in the head and neck region, where they can involve any anatomic site. Laryngeal involvement, however, is quite rare. Lipoma is recognised as a slow growing, benign mesenchymal tumour; myxolipoma is a rare variant which has a prominent myxoid background. Laryngeal lipoma is infrequent, accounting for only 0.6% of all benign laryngeal lesions. We report a 61-year-old male patient with laryngeal nodular fasciitis coexisting with myxolipoma who presented to a tertiary care hospital in Ar Ramtha, Jordan, in 2020. Radiological and histological findings were indicative of laryngeal nodular fasciitis and myxolipoma was incidentally diagnosed. Following trans-oral debulking of the lesion the mass enlarged rapidly and the patient underwent a tracheostomy with complete mass excision and right partial laryngectomy through an open surgical approach. The patient had an uneventful recovery with no evidence of recurrence. The purpose of this report is to broaden the differential diagnosis of rapid-growing laryngeal masses that cause airway obstruction and to stress the significance of integrative interdisciplinary collaboration to establish an accurate diagnosis, thereby allowing proper management for benign pathologies and avoid futile aggressive treatment.
