Summary 

Inflammatory myofibroblastic tumor (IMT) of larynx is an unusual benign proliferate lesion rarely seen in pediatric age group. A 10-year-old male child presented with history of hoarseness of voice for 6-month duration and indirect laryngoscopy showed an ulcerative, warty growth involving the right vocal cord. The patient underwent microlaryngeal surgery under general anaesthesia and growth was excised completely. The histopathology showed spindle cells arranged in fasciculate pattern with myxoid background and focal hyalinization. The immunostaining showed positivity of spindle cells to vimentin and muscle specific actin confirming the diagnosis of IMT. The voice of child improved after 2 months and had regular follow up for 2 years with no recurrence.
