RESUMEN
A 70-year-old female presented with a swelling in the right auricle for 6 months. Rapid onsite stain and routine cytology revealed clusters of small, round to oval cells with hyperchromatic nuclei, inconspicuous nucleoli, and scant cytoplasm. The background had basement membrane type material and appeared dark magenta colored pinkish globular material. Hence a cytological diagnosis of skin adnexal tumor possibly cylindroma was made. The excision of the lesion also showed features of cylindroma. Rapid onsite staining and cytology of subcutaneous location of the tumor in the absence of primary salivary gland tumors may help to diagnose such rare cases.

Carotid body tumors (CBTs) are paragangliomas which arise from the chief cells of the carotid body, usually located at the bifurcation of the common carotid artery. A 45-year-old male presented with swelling over the right cervical region for 1 year. Based on location, FNA and radiologic investigations, the diagnosis of CBT was made; later, confirmed on histopathology. Although FNA is seldom suggested due to its location and possibility of severe bleeding complications for the diagnosis of CBT, it can however be detected incidentally. Our case, the diagnosis was incidental cytological diagnosis on rapid onsite staining.
