Cytodiagnosis of epidermoid cyst of the upper lip: a common lesion in an uncommon site.
Epidermoid cyst and dermoid cysts are developmental pathologies thought to derive from aberrant ectodermal tissue. They are uncommon in the head and neck region. Rarely, they can be found in the oral cavity and buccal mucosa. However, epidermoid cyst is extremely uncommon in the upper lip and is rarely reported. In this study, we report an uncommon case of epidermoid cyst occurring in the upper lip diagnosed by fine-needle aspiration cytology (FNAC). We present this case because of its extremely rare site of presentation and also to highlight the role of FNAC to in the pre-operative diagnosis of this benign lesion.
