Bilateral Enlarged Bumps on the Back of the Tongue
The most critical first step is to determine whether these bumps represent normal anatomical structures (circumvallate papillae) versus pathology requiring biopsy—any asymmetry, ulceration, induration, or associated lymphadenopathy mandates immediate tissue biopsy to exclude malignancy. 1
Initial Clinical Assessment
The evaluation must distinguish between benign physiologic findings and pathologic lesions that require intervention:
Key Features Requiring Biopsy
- Unilateral or asymmetric lesions warrant immediate tissue sampling 1
- Ulcerated or indurated lesions require histological confirmation 1
- Lesions associated with a discrete mass must be biopsied 1
- Presence of cervical lymphadenopathy necessitates tissue diagnosis 1
- Significant tobacco/alcohol history increases malignancy risk and lowers threshold for biopsy 1
Physical Examination Specifics
- Manual palpation of the tongue base to assess for tumor 2
- Bimanual palpation to examine tissue consistency and fixation 2
- Measurement of lesion dimensions and documentation of morphology (exophytic, infiltrating, or ulcerative) 2
- Assessment of mobility and infiltration of adjacent structures 2
- Cervical lymph node examination noting presence, sites, dimensions, mobility, and number 2
Diagnostic Workup for Suspicious Lesions
If clinical features suggest pathology rather than normal anatomy:
Mandatory Studies
- Biopsy for histological confirmation when malignancy cannot be excluded 2, 1
- Chest X-ray to evaluate for synchronous bronchial tumors 2
- Neck CT with contrast or MRI for patients at increased risk for malignancy 2
Optional Studies Based on Risk Factors
- Panendoscopy if prolonged alcohol and tobacco use history 2
- Cervical ultrasonography to evaluate cervical nodes in obese patients 2
Treatment Based on Diagnosis
If Benign Cobblestoning (Lymphoid Hyperplasia)
Treatment focuses on addressing underlying irritants: 1
- Intranasal corticosteroids or antihistamines for postnasal drainage 1
- Proton pump inhibitors for gastroesophageal reflux management 1
- Elimination of irritants (smoking, alcohol) 1
- Adequate hydration maintenance 1
- Reassessment in 4-6 weeks after treating underlying causes, with immediate biopsy if appearance changes 1
If Malignancy Confirmed
For T1-T2 tongue cancer: 3
- Surgical excision with neck dissection (ipsilateral or bilateral based on tumor thickness) 3
- Bilateral neck dissection should be considered for anterior tongue cancers due to 50-60% rate of occult metastases 3
- Single-modality treatment preferred to avoid compromising functional outcomes 3
For T3-T4 advanced disease: 3
- Surgery followed by adjuvant therapy is the recommended approach 3, 4
- Postoperative chemoradiotherapy (Category 1) for extracapsular nodal spread and/or positive margins 3
- Concurrent cisplatin 100 mg/m² every 3 weeks with radiation 3
If Other Benign Pathology
- Lipomas: Surgical excision is curative 5, 6
- Lymphangiomas: Early tongue reduction if causing protrusion, followed by CO2 laser photocoagulation for recurrences 7
- Tongue abscess: Incision and drainage under general anesthesia with antibiotic coverage for gram-positive and gram-negative anaerobes 8
Critical Timing Considerations
Adjuvant therapy must begin within 6 weeks post-surgery—delays beyond this timeframe negatively impact outcomes and survival 3, 4
Common Pitfalls to Avoid
- Dismissing bilateral symmetric bumps as normal without proper examination—circumvallate papillae are normal, but pathology can be bilateral 6
- Delaying biopsy in patients with risk factors (tobacco/alcohol use) significantly impacts survival, as early-stage disease achieves 75-90% local control versus 37-72% for advanced disease 1
- Underestimating occult neck metastases risk in anterior tongue lesions (50-60% rate) 3
- Combining surgery with radiotherapy for early-stage disease unnecessarily compromises functional outcomes 3
