Spheno-occipital chordomas can rarely present as nasopharyngeal mass. Metastases occur only in advanced disease. They can pose a diagnostic dilemma when information about diagnosis of the primary tumor is not available. We present cytological findings in upper cervical lymph node of a case of nasopharyngeal chordoma and discuss possible differential in such a location. [ABSTRACT FROM AUTHOR]

Proliferating trichilemmal tumor (PTT) is a benign tumor originating from the outer root sheath of a hair follicle. Malignant transformation in case of PTT is very rare and unusual finding. It is usually confused with squamous cell carcinoma both sharing many common features. So the identification of malignant PTT is very essential. Only 39 well-documented cases of malignant proliferating trichilemmal cyst have been published to date in the English language literature. We hereby present a case of a 75-year-old female patient with a rapidly growing swelling on the scalp. [ABSTRACT FROM AUTHOR]
