Laryngeal Giant Cell Tumor : A Case Report and Review of the Literature

الملخص EN

Giant cell tumor (GCT) is a benign neoplasm arising most commonly in the long bones.

GCTs of the larynx (GCTL) are relatively rare, and only individual case reports are documented in the literature.

Patients with such tumors may present with hoarseness and anterior neck swelling.

We present a 59-year-old man with hoarseness and enlarging anterior neck mass for 3 months.

A fiberscopy revealed a submucosal swelling of the left subglottic trachea.

Computed tomography and magnetic resonance imaging of the larynx demonstrated a large, well-defined, inhomogeneous enhancing mass at the left thyroid cartilage, which was obstructed entirely.

The anterior neck mass was biopsied for histopathological analysis, which showed multinodularity with intervening vascularized connective tissues.

The mass was made up of mononuclear cells and distributed multinucleated giant cells.

The mitotic activity of the mononuclear cells was as high as 6 per 10 high-power fields.

Pathologic consultation resulted in a diagnosis of giant cell tumor.

The patient underwent total laryngectomy and, postoperatively, he did well without recurrence or metastasis for two and a half years.
