Spindle Cell Lipoma within the Larynx: A Case Report with Correlated Light and Electron Microscopy
1993
A spindle cell lipoma was removed surgically from the right intralaryngeal lesion of a 68-year-old man. Laryngoscopy demonstrated a spherical protrusion with intact mucosa near the vestibular fold. CT scan examination showed a low-density mass just medial to the thyroid cartilage. Light microscopy revealed that the circumscribed tumor consisted of mature lipocytes and spindle cells. Electron microscopy revealed that the spindle cells lacked a typical basal lamina. Such tumors are more frequent in the posterior aspect of the neck and shoulder regions. To our knowledge, this is the first reported case of a spindle cell lipoma within the larynx.
