Gesundheitliche Auswirkungen beim regelmäßigen Kauen von Kolanüssen
Clinical Case Summary
The patient presents with a large (3-4 cm), asymmetric, ulcerated, and exophytic plaque on the tongue. The lesion is characterized by a mixed red-white appearance, a warty surface, and central crusting/exudate. The patient reports a chronic course (over one year), progressive growth, and pain. Notably, the patient reports the habit of chewing „Kola nuts,“ which may represent a chronic irritant or be associated with specific regional mucosal changes, though this does not explain the high-risk morphological features.
Extracted Variables
- new_lesion: yes (detected by dentist, progressive growth)
- malignancy_suspected: yes
- cause_plausible: yes (Kola nut chewing as a potential chronic irritant), cause_description: chronic mechanical/chemical irritation from nut chewing
- residual_uncertainty: yes
- regression_after_2w: not assessable
- complete_regression_after_4w: not assessable
- brush_cytology_result: not performed
- histology_result: not performed
Red Flag Assessment
- ulceration or erosion: present
- red-white inhomogeneous character: present
- pronounced hyperkeratosis: present (warty/papillomatous surface)
- bleeding: not detectable / unclear (patient denies, but surface is described as friable)
- conspicuous vascular pattern: present (punctate red vessels/dotted vessels)
- exophytic / raised / mass-like: present
- induration: present (irregular, raised, and indurated border)
- progressive / duration unclear / new: present (duration > 1 year, growing)
- no plausible cause: unclear (nut chewing is a possible trigger, but insufficient to explain malignancy-like morphology)
- conspicuous lymph nodes: not mentioned
Triage Decision
Triage Level A: suspicion of malignancy / malignant lesion
Justification: The lesion exhibits a constellation of high-risk „red flags,“ including an exophytic growth pattern, central ulceration, an inhomogeneous red-white surface, and induration of the borders. The progressive nature over a year and the presence of punctate vascular patterns are highly suggestive of a malignant process (e.g., Squamous Cell Carcinoma or Verrucous Carcinoma). While the chewing of Kola nuts is a reported habit, the clinical morphology far exceeds a simple reactive lesion, necessitating immediate specialist intervention.
Recommendation and Next Step
Immediate referral to an oral and maxillofacial surgeon or a specialized oral pathology clinic for urgent biopsy and histopathological staging.
The patient’s question regarding the Kola nut should be addressed by the specialist; while such habits can cause mucosal changes or act as co-carcinogens, the current clinical presentation is highly concerning for malignancy regardless of the trigger.
Follow-up Questions
No further questions are required at this stage, as the clinical findings and red flags are sufficient to trigger Triage Level A.
Dear Colleague,
Thank you for referring this patient for the evaluation of a lesion on the tongue.
HISTORY
- Reason for presentation: The patient presents with pain in the oral cavity.
- First manifestation: The lesion was noted by the treating dentist.
- Time course: The lesion has been present for approximately one year or longer. The patient reports a slow progression in size.
- Current symptoms: The patient reports pain and a sensation of „loose teeth,“ which may indicate deep infiltration or periodontal involvement.
- Bleeding history: No spontaneous or contact bleeding reported.
- Risk factors:
- Tobacco: 20 cigarettes per day. (Assuming a long-term habit, e.g., 30 years, this would be 30 pack-years).
- Alcohol: Three beers per day (high regular use).
- Betel quid / areca nut: The patient reports regular chewing of „Kola nut.“ While kola nuts differ from areca nuts, any habitual nut-chewing associated with oral mucosal changes warrants high suspicion.
- The combination of chronic tobacco and alcohol use is an established synergistic risk factor for malignant transformation of oral mucosal lesions.
- Aetiology: No obvious mechanical or iatrogenic cause was identifiable from the history.
IMAGE ANALYSIS
The provided clinical image was analyzed by a dermatology-trained vision model applied off-label to the oral mucosa; findings are used as descriptive morphology and skin analogues only.
- Lesion morphology: The image shows a large (approx. 3-4 cm), asymmetric, ulcerated plaque with exophytic and fungating components located on the tongue. The border is irregular, raised, and indurated. The surface is mixed red-white with a central yellowish exudate and crust. Diffuse erythema with punctate red vessels („dotted vessels“) is visible within the inflamed base.
- Closed-vocabulary morphology tokens: SkinCon features present:
Abscess,Atrophy,Black,Brown(Hyperpigmentation),Crust,Dome-shaped,Erosion,Erythema,Exophytic/Fungating,Exudate,Friable,Gray,Induration,Macule,Nodule,Patch,Pedunculated,Pigmented,Plaque,Purple,Purpura/Petechiae,Pustule,Salmon,Scale,Scar,Sclerosis,Telangiectasia,Translucent,Ulcer,White(Hypopigmentation),Warty/Papillomatous,Yellow. - Concern level & red flags: Concern Level 1 (Highest). Red flags identified: Ulceration, exophytic growth, mixed red-white appearance, irregular border, exudate, and mucosal atrophy. The visual analogue is an ulcerated verrucous nodule.
- Confidence & image quality: Confidence is Moderate; Overall quality is 7/10, and adequacy is Sufficient.
ALGORITHMIC ASSESSMENT (S2k 007-092)
- Red-flag screen: Multiple red flags are present: Ulceration with raised/indurated margins, a history of rapid/progressive growth (Q4), and Concern Level 1 from image analysis.
- Decision-tree walk-through:
- New clinical change? Yes.
- Clinical suspicion of malignancy? Yes (based on induration, ulceration, mixed red-white morphology, and high-risk profile).
Terminal Node: BIOPSY.
AIDOCVISION RESEARCH INDEX (institutional, advisory, revised build)
| Item | Score | Rationale |
|---|---|---|
| Q1 Reason | 3 | Symptoms present (pain) |
| Q2 Detection | 5 | Referred by dentist for suspicion |
| Q3 Duration | 5 | >6 weeks / chronically non-healing |
| Q4 Course | 3 | Slow size change |
| Q5 Symptoms | 4 | Tooth loosening |
| Q6 Bleeding | 1 | None |
| Q7 Smoking | 4 | 20 cig/day (estimated 20-30 py) |
| Q8 Alcohol | 4 | High regular use |
Calculation:
AIDOCVISION-rev = $(1.5\cdot5 + 1.5\cdot3 + 1.2\cdot4 + 1.2\cdot1 + 0.8\cdot4 + 0.8\cdot4 + 0.5\cdot3 + 0.5\cdot5) / 8.0$
$= (7.5 + 4.5 + 4.8 + 1.2 + 3.2 + 3.2 + 1.5 + 2.5) / 8.0$
$= 28.4 / 8.0 = 3.55$
Synergism Bonus: $+0.3$ (Tobacco $\ge 4$ and Alcohol $\ge 4$)
Final Score: 3.85 $\rightarrow$ Higher Concern Band ($\ge 3.1$)
- Disagreement rule: The AIDOCVISION-rev band agrees with the S2k 007-092 terminal node.
- Concordance: Concordant (Higher concern index + Concern Level 1).
IMAGE vs. WORKING DIAGNOSIS
The parsed image findings (ulcerated, exophytic, indurated plaque) are highly concordant with the history of chronic irritation and high-risk habits. The visual appearance is classic for a malignant process, and the history of „loose teeth“ suggests deep invasion.
DIFFERENTIAL DIAGNOSES
- Squamous Cell Carcinoma (SCC): Most likely given the ulcerated, exophytic morphology, indurated borders, „dotted“ vessels, and heavy tobacco/alcohol load.
- Verrucous Carcinoma: Suggested by the „warty/papillomatous“ surface and slow growth pattern.
- Oral Potentially Malignant Disorder (OPMD) / Leukoplakia: The mixed red-white (erythroleukoplakic) appearance may represent a precursor lesion currently undergoing malignant transformation.
- Deep Fungal Infection / Chronic Ulcer: Less likely, but can mimic malignancy in chronic cases.
Given the biopsy-branch outcome and multiple red flags, a malignant process cannot be excluded and requires urgent histopathological confirmation.
PLANNED MANAGEMENT
Following the AWMF S2k 007-092 algorithm:
– Urgent Incisional Biopsy: A biopsy will be performed promptly. Samples will be taken from the periphery/margin of the lesion, avoiding the necrotic central ulcerated zone.
– Further Step: Depending on the histology (Dysplasia/SCC), the patient will be referred to a specialized head and neck surgical center for definitive treatment.
– Cessation Counselling: The patient has been strongly advised to cease tobacco use, alcohol consumption, and the chewing of kola nuts.
Safety-netting: The patient was instructed to re-present immediately if there is a rapid increase in size, spontaneous bleeding, or new difficulty swallowing (dysphagia).
Follow-up: Histopathology results will be reviewed in 7–10 days.
Sincerely,
