      History of Present Illness

      A 53‐year‐old man presents with a 1‐month history of tongue soreness and pain. He has not noticed any change in voice, difficulty swallowing, or a neck mass. However, the tongue pain is persistent and has not gone away with over‐the‐counter medications. His past medical history includes type II diabetes, controlled with oral agents, and hypertension. He does not smoke and has no history of tobacco or alcohol abuse. No other past medical history was identified.

       Question: What would you recommend next?

      Answer: Tissue sampling with a punch or incisional biopsy of the lesion, preferably from the corner of the lesion.

       Question: The biopsy shows squamous cell carcinoma (SCC ), moderately differentiated, with a depth of invasion of at least 4 mm (punch biopsy specimen with tumor transected at the base). What would you recommend next in the workup?

      Answer: Imaging of the neck is usually recommended to assess lymph node involvement. A computed tomography (CT) scan with contrast or an ultrasound of the neck (which can be performed in the clinic) are both reasonable first options. The risk of distant metastases in early (T1 and T2) oral cavity SCC is extremely low. Therefore, extensive metastatic workup is not necessary. While positron emission tomography (PET)/CT has become more common, the evidence for its added benefit does not exist. Obtaining a chest CT to rule out lung metastases is considered adequate.

       Question: A CT scan of the head and neck does not show any evidence of regional metastases. How would you clinically stage this disease?

      Answer: Based on the AJCC staging manual, 8th Edition, the clinical stage is cT1N0Mx, stage I.

       Question: What treatment would you recommend?

      Answer: Early stage tongue cancer treatment is wide local excision of the primary tumor and addressing the regional lymph nodes. If the risk of regional lymph node metastases is presumed to be higher than 20%, an elective, selective neck dissection should be performed. Depth of invasion is a prognostic marker for the presence of occult nodal metastases in the cN0 neck. With a depth of invasion >3 mm, it is believed that the risk of occult nodal metastases is >20%, and therefore an elective neck dissection should be performed. In this scenario, the recommended treatment is wide local excision of the primary tumor with 1 cm margins and elective neck dissection (ipsilateral levels I–III, i.e., supra‐omohyoid neck dissection). Alternatively, sentinel node biopsy could be offered if adequate expertise in the treating facility exists.

       Question: Patient undergoes sentinel node mapping followed by wide local excision and sentinel node biopsy. The tongue defect is repaired with biologic dressing and secondary intention closure. On lymphoscintigraphy, the sentinel node is located in an ipsilateral level II lymph node (Figure 1.2). Excisional biopsy and frozen section assessment shows metastatic SCC in the level II node. How would you proceed?
