Abstract

Background.

We describe, for the first time, the occurrence of two pure examples of spindle cell neoplasm with fibrous and smooth muscle differentiation in the larynx.

Materials and Method.

Tissue sections from both tumors stained with hematoxylin and eosin were reviewed. Immunophenotypic analysis using keratin, S‐100 protein, SMA, and h‐Caldesmon markers was performed.

Results.

Tumors were seen as raised submucosal nodules in the glottic region of two elderly male patients. Histopathologically, the lesions were unencapsulated and composed of spindle cells that manifested variable cellular anaplasia and expressed SMA and were negative for keratin, S‐100, and h‐Caldesmon.

Conclusions.

We document histologically low‐grade malignant myofibroblastic tumors of the larynx. Complete excision is advised. Β© 2003 Wiley Periodicals, Inc. Head Neck 25: 606–611, 2003
