title: Tattoo-pigmented cervical lymph node that masqueraded as the sentinel lymph node in oral squamous cell carcinoma.
abstract: We describe a case of a pigmented cervical lymph node mimicking the sentinel node during sentinel lymph node biopsy (SLNB) on a patient with oral squamous cell carcinoma (OSCC). The patient had extensive tattoos on his neck. This pigmented lymph node was not identified to be the sentinel lymph node using static and dynamic lymphoscintigraphy. Subsequent histological analysis revealed tattoo pigment within this lymph node. It is important during cervical SLNB to be aware that cutaneous tattoos can pigment lymph nodes.
