Abstract |
Adenosquamous carcinoma (ASC) of the larynx is very rare malignancy which has well defined two distinctive pathological features, an adenocarcinoma and a squamous cell carcinoma (SCC). Diagnosis of ASC by endoscopic biopsy is challenging due to small amount of harvested tissue. ASC has a worse prognosis than SCC with an early lymph node metastasis and a distant dissemination. We experienced a rare case of vocal fold ASC which was initially misdiagnosed as atypical squamous cell proliferation at frozen biopsy. We reported this case with a literature review. |
