Ursachenklärung bei Krebsverdacht und familiärer Vorbelastung
Clinical Assessment Summary
The patient presents with a solitary, irregularly shaped ulcerative lesion on the oral mucosa (described as buccal/labial in image analysis, though the patient refers to the tongue). The lesion is characterized by a yellowish-white fibrinous base and an erythematous halo, appearing friable. The patient reports a duration of several weeks, progressive worsening, numbness of the tongue, and spontaneous bleeding. Significant risk factors include heavy smoking (40 cigarettes/day) and alcohol consumption (5 beers/day). The patient explicitly expresses concern regarding malignancy due to a positive family history of cancer.

Red Flag Analysis
Ulceration or erosion: present
Red-white inhomogeneous character: present (yellowish-white base with erythematous halo)
Pronounced hyperkeratosis: not mentioned
Bleeding: present
Conspicuous vascular pattern: not mentioned
Exophytic / raised / mass-like: not mentioned (described as depressed/ulcer)
Induration: not mentioned (not assessable via text/image)
Progressive / duration unclear / new: present
No plausible cause: present
Conspicuous lymph nodes: not mentioned
Triage Decision
Triage Level A: suspicion of malignancy / malignant lesion
Justification: The combination of a chronic, non-healing ulcer, spontaneous bleeding, and sensory deficits (numbness) in a patient with high-risk habits (heavy smoking and alcohol) and a family history of malignancy constitutes a high clinical suspicion of squamous cell carcinoma (SCC). The presence of multiple strong red flags necessitates immediate specialized intervention.
Recommendation
Next Step: Immediate referral to a specialist for biopsy and comprehensive oncological staging.
Given the high risk profile and clinical presentation, this case requires urgent histopathological clarification.
Follow-up Questions
No further follow-up questions are required to determine the triage level, as the current red flags and risk factors are sufficient for Level A.
Dear Colleague,
Thank you for referring this patient for the assessment of a lesion in the oral cavity. Please find my detailed assessment and the planned management based on the AWMF S2k-Guideline 007-092 below.
HISTORY
- Reason for presentation: The patient presents for the evaluation of a lingual lesion identified during a routine dental examination.
- First manifestation: The change was first noticed by the referring dentist; the patient was initially asymptomatic.
- Time course: The lesion has been present for several weeks. The patient reports an increasing difficulty/discomfort („something is not right with the tongue“) and a progressive course.
- Current symptoms: The patient reports a distinct numbness (hypoaesthesia) in the area of the tongue.
- Bleeding history: Spontaneous bleeding has been observed for the past week.
- Risk factors:
- Tobacco: 40 cigarettes per day. (Assuming 30 years of smoking for calculation: $(40/20) \times 30 = 60$ pack-years).
- Alcohol: Chronic high intake (5 beers per day).
- Betel quid / areca nut: Not reported.
- The combination of $>30$ pack-years and chronic 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.
ALGORITHMIC ASSESSMENT (S2k 007-092)
- Red-flag screen: Multiple red flags present: spontaneous bleeding and hypoaesthesia (numbness) in the lesion’s territory.
- Decision-tree walk-through:
- Complete examination: Yes.
- New clinical change? $\rightarrow$ YES.
- Clinical suspicion of malignancy? (Based on red flags: spontaneous bleeding, paraesthesia, and image appearance) $\rightarrow$ YES.
- Terminal Node: Node B — BIOPSY.
AIDOCVISION RESEARCH INDEX (institutional, advisory, revised build)
| Item | Value | Reasoning |
|---|---|---|
| Q1 Reason for visit | 3 | Symptoms present / referred |
| Q2 Detection | 5 | Referred by dentist for suspected problem |
| Q3 Duration | 3 | Present for „several weeks“ (3-6 wk band) |
| Q4 Course | 5 | Rapid progression / „increasingly difficult“ |
| Q5 Symptoms | 5 | Paraesthesia/Hypoaesthesia |
| Q6 Bleeding | 5 | Spontaneous |
| Q7 Smoking | 5 | $>30$ pack-years |
| Q8 Alcohol | 5 | High chronic |
Calculation:
$\text{AIDOCVISION-rev} = (1.5 \cdot 3 + 1.5 \cdot 5 + 1.2 \cdot 5 + 1.2 \cdot 5 + 0.8 \cdot 5 + 0.8 \cdot 5 + 0.5 \cdot 3 + 0.5 \cdot 5) / 8.0$
$\text{AIDOCVISION-rev} = (4.5 + 7.5 + 6.0 + 6.0 + 4.0 + 4.0 + 1.5 + 2.5) / 8.0 = 36.0 / 8.0 = \mathbf{4.5}$
Synergism Bonus: Q7 $\ge 4$ and Q8 $\ge 4 \rightarrow +0.3$
Final Score: $\mathbf{4.8}$
Band: Higher concern ($\ge 3.1$)
Disagreement Rule: The AIDOCVISION-rev band (Higher concern) agrees with the 007-092 terminal node (Biopsy).
IMAGE vs. WORKING DIAGNOSIS
The intraoral photograph reveals a solitary, irregularly shaped ulcer with a yellowish-white fibrinous base and a surrounding erythematous halo. The friable appearance and central depression are highly characteristic of a malignant ulceration. The image findings strongly correlate with the history of bleeding and numbness, supporting a high suspicion of malignancy.
DIFFERENTIAL DIAGNOSES
- Squamous Cell Carcinoma (SCC): Leading diagnosis. Driven by the high-risk profile (tobacco/alcohol), the ulcerated morphology, spontaneous bleeding, and sensory loss (nerve infiltration).
- Major Aphthous Ulcer / Severe Erosive Ulcer: Less likely given the lack of spontaneous resolution over weeks, the lack of typical „geographic“ borders, and the presence of numbness.
- Deep Fungal Infection (e.g., Histoplasmosis): Possible in immunocompromised states; presents as a non-healing ulcer, but the synergistic risk factors point more strongly toward SCC.
- Tuberculous Ulcer: Rare, but can present as a chronic oral ulcer; usually associated with pulmonary symptoms.
Given the red-flag findings (bleeding and hypoaesthesia), a malignant process cannot be excluded clinically and requires histopathological confirmation.
PLANNED MANAGEMENT
Following the 007-092 algorithm (Node B), the management is as follows:
- Incisional Biopsy: To be performed urgently. The specimen will be taken from the periphery/margin of the lesion to ensure viable tissue is captured, avoiding the necrotic central ulcer base.
- Histopathological Correlation:
- If high-grade dysplasia, Carcinoma in situ, or SCC is confirmed $\rightarrow$ immediate referral to a multidisciplinary head and neck oncology center for staging and surgical planning.
- If low-grade dysplasia $\rightarrow$ close observation.
- If benign $\rightarrow$ treat according to specific etiology.
- Cessation Counselling: The patient will be strongly advised to cease tobacco and alcohol consumption to mitigate further risk and improve surgical outcomes.
Safety-netting: The patient was instructed to re-present immediately if there is a rapid increase in lesion size, new/heavy bleeding, progressive pain, or new dysphagia.
Follow-up: Biopsy results are expected within 5–7 business days; a follow-up appointment is scheduled for [Insert Date].
