Since the outcome of treatment depends on identifying the correct diagnosis and having the correct treatment on time, it is essential to differentiate keratoacanthoma and squamous-cell carcinoma as soon and accurately as p...

Tonsillar squamous cell carcinoma, which represents 10% of head and neck malignancies, rarely manifests with cutaneous metastases; to date, only three prior patients with tonsillar squamous cell carcinoma have been reported to develop cutaneous metastases. We describe the clinical features of a 59-year-old man with squamous cell carcinoma of the tonsil who developed cutaneous metastases within ...
