Study Notes
Clinical Classification of Ulcers
- Spreading Ulcer: Characterized by inflamed and edematous edges.
- Healing Ulcer: Has sloping edges with healthy red granulation tissue and serous discharge.
- Callous Ulcer: Presents pale unhealthy granulation tissue with an indurated edge.
Pathological Classification of Ulcers
- Nonspecific Ulcers: Includes traumatic, arterial, venous, neurogenic, and infectious ulcers.
- Specific Ulcers: Associated with distinct infections/diseases like tuberculosis, syphilis, actinomycosis, Meleney’s ulcer (type of necrotizing fasciitis), and soft sore.
- Malignant Ulcers: Types include squamous cell carcinoma (Sq.C.C), basal cell carcinoma (B.C.C), and malignant melanoma (M.M).
History Taking for Ulcers
- Key details include mode of onset, duration, pain, discharge, and any associated diseases.
Physical Examination of Ulcers
- Conduct a general survey including inspection, palpation, lymph nodes examination, vascular insufficiency, and detecting nerve lesions.
Inspection Guidelines
- Size and Shape: Assess the dimensions and contour of the ulcer.
- Number: Note if solitary or multiple.
- Position: Determine the location in relation to other anatomical features.
- Edge: Analyze the border of the ulcer.
- Floor: Examine the exposed surface.
- Discharge: Identify the type and quantity.
- Surrounding Area: Note any changes in skin appearance.
Position-Specific Ulcer Locations
- Arterial Ulcer: Found at the tip of the toes or dorsum of the foot.
- Venous Ulcer: Located on the medial side of the leg (long saphenous varicosity) or lateral side (short saphenous varicosity).
- Perforating Ulcers: Occur over pressure points on the sole.
- Nonhealing Ulcer: Typically on the shin.
Edge Characteristics of Ulcers
- Sloping Edge: Common in healing ulcers.
- Punched Out Edge: Seen in gummatous and trophic ulcers.
- Raised Edge: Indicative of rodent ulcers or basal cell carcinoma.
- Everted Edge: Typical for squamous cell carcinoma.
Floor of the Ulcer
- Defined as the exposed part of the ulcer where it rests, important for diagnosis.
Discharge Types from Ulcers
- Serous Discharge: Indicates healing.
- Purulent Discharge: Associated with spreading ulcers.
- Bloody Discharge: Common in malignant ulcers.
- Greenish Discharge: Suggests Pseudomonas infection.
Assessment of Induration
- Maximum Induration: Linked with squamous cell carcinoma.
- Minimal Induration: Often seen in malignant melanoma.
- Brawny Induration: Associated with abscesses.
- Cyanotic Induration: Related to chronic venous congestion.
Surrounding Skin Characteristics
- Thickening and induration suggest squamous cell carcinoma.
- Tenderness and pitting signal spreading inflammation.
Clinical Examination of Lymph Nodes
- Tender and enlarged nodes indicate acute infections, while non-tender and hard nodes suggest chronic infections or malignancies.
Remembering Key Components in Ulcer Examination (Mnemonic: DRESSINGS)
- D: Discharge and Depth
- R: Relation to underlying structures
- E: Edge and Margin
- S: Site, Size, Shape, Surface, Surrounding area
- S: Solitary or multiple?
- I: Induration and Impairment of circulation
- N: Enlarged nodes and neurologic deficits
- G: General examination for conditions like malnutrition or heart failure
- S: Biopsy for culture, sensitivity, and further investigations as needed.
Key Points for Ulcer Understanding
- Ulcers are defined as breaks in epithelial continuity of tissues.
- Importance lies in recognizing clinical signs for diagnosis and treatment planning.
- Various factors including ulcer classification significantly influence management strategies.
