Coexistence of Basaloid Squamous Cell Carcinoma and Large Cell Neuroendocrine Carcinoma in the Larynx: A Case Report and Literature Review

Basaloid squamous cell carcinoma and large cell neuroendocrine carcinoma are not common in head and neck, these tumors rarely occur in the larynx but both have highly aggressive clinical behavior and a high mortality rate. The diagnosis is complicated by these tumors' atypical clinical and pathological features. This case details a coexistence of basaloid squamous cell carcinoma and large cell neuroendocrine carcinoma of a woman in the larynx. The patient underwent endoscopy- and coblation-assisted transoral microsurgery to achieve hyoid horizontal epiglottidectomy and has no recurrence after 12 months of follow-up.
