Abstract
Laryngeal sarcocystosis is an uncommon zoonotic coccidian protozoal infestation of human beings. The authors reviewed the pathology of 1,063 laryngeal biopsies over the past 10 years (2000 to 2009). Only one case of laryngeal sarcocystosis accompanying laryngeal squamous cell carcinoma was identified. The overall prevalence of laryngeal sarcocystosis was 0.094%. The case was a 66-year-old man who presented with voice hoarseness for six months. Physical examination and computed tomography revealed an ulcerative exophytic mass on the right true vocal cord, suggestive of laryngeal carcinoma. He underwent a right frontolateral partial laryngectomy. Histopathology showed a nonkeratinizing squamous cell carcinoma with Sarcocystis spp in the vocalis muscle. He was followed up and enrolled in speech therapy. The authors briefly review the clinicopathologic features and pathogenesis of muscular sarcocystosis and concurrent laryngeal sarcocystosis and squamous cell carcinoma.
