Mesenchymoma of larynx and neck.

A case of mesenchymoma of the larynx and neck with respiratory obstruction is presented. Mesenchymoma is a rare lesion in the head and neck area in which fibrous tissue is accompanied by two other mesenchymal components, often with an infiltrating margin in benign forms. The majority appear in patients under 25 years of age, most commonly in the subcutaneous scalp, cheek, or tongue. There is a 20% recurrence rate. A malignant type also occurs. Wide surgical excision is the treatment of choice.
