Corn Biopsy - Medium 1-3 cm
- Why is it done?
- Histopathological examination of skin lesions on the feet to differentiate between benign corns and other dermatological conditions such as warts, calluses, or malignant lesions
- To confirm diagnosis of heloma (corn) and rule out other pathological conditions including plantar warts, squamous cell carcinoma, or other malignant growths
- When clinical examination is inconclusive or when lesions fail to respond to conservative treatment
- To assess for secondary infections or inflammatory complications
- Performed when lesions are 1-3 cm in diameter, representing medium-sized pathological specimens requiring tissue analysis
- Normal Range
- Normal/Benign Findings: Characteristic hyperkeratotic core with concentric arrangement of keratin layers, intact basement membrane, and absence of malignant cells
- Interpretation Categories:
- Benign Corn (Heloma Durum): Positive confirmation with normal histology
- Normal Skin: Absence of pathological changes, normal epidermal-dermal architecture
- Units of Measurement: Histological findings reported descriptively with specific architectural features noted
- Size Reference: Medium biopsy specimens of 1-3 cm diameter provide adequate tissue for comprehensive histopathological assessment
- Interpretation
- Benign Corn (Heloma Durum): Shows dense keratin core with concentric lamellation, surrounding inflammatory infiltrate minimal, basement membrane intact, no atypia present
- Plantar Wart (Verruca Vulgaris): Demonstrates thickened epidermis with columnar parakeratosis, rete ridges elongated with cupping, viral changes with koilocytes may be present
- Callus (Tyloma): Shows diffuse hyperkeratosis and acanthosis without central keratinous core, normal skin architecture with mild inflammatory changes
- Squamous Cell Carcinoma: Demonstrates atypical keratinocytes, increased mitotic figures, abnormal nuclear features, invasion into dermis, loss of normal architecture
- Inflammatory Changes: May indicate secondary infection, immunological response, or irritation from chronic pressure
- Factors Affecting Results: Proper tissue fixation, specimen orientation, adequate sampling, recent treatment history, immunological status of patient
- Associated Organs
- Primary System: Integumentary system (skin and soft tissues of the foot)
- Musculoskeletal System: Involvement of underlying bony structures, pressure-related joint complications
- Associated Conditions with Abnormal Results:
- Heloma durum (hard corn) - most common benign finding with typical concentric keratin layers
- Plantar warts caused by human papillomavirus (HPV) infection with potential for malignant transformation
- Cutaneous malignancies including squamous cell carcinoma and melanoma
- Secondary bacterial infections leading to cellulitis or abscess formation
- Inflammatory dermatological conditions and autoimmune manifestations
- Potential Complications:
- Pain and functional impairment affecting gait and mobility if malignancy detected
- Risk of metastatic disease if malignant lesion is identified
- Post-biopsy bleeding, infection, or scarring at biopsy site
- Follow-up Tests
- If Benign Corn Confirmed:
- Clinical follow-up examination in 2-4 weeks to assess healing and treatment response
- Podiatric assessment for biomechanical correction and pressure-relieving interventions
- If Plantar Wart Identified:
- HPV typing may be considered for high-risk strains
- Dermatological referral for cryotherapy, laser therapy, or immunological treatment
- Follow-up examination at 3-6 month intervals to monitor for recurrence
- If Malignancy Suspected or Confirmed:
- Urgent oncology consultation and staging workup (imaging, additional biopsies if indicated)
- CT or MRI imaging for assessment of local extension and metastatic disease
- Sentinel lymph node biopsy if melanoma or high-grade carcinoma identified
- Surgical excision with wide margins as primary treatment modality
- If Secondary Infection Present:
- Bacterial culture and sensitivity testing if not already performed
- Antibiotic therapy based on culture results
- Follow-up assessment in 1-2 weeks to confirm infection resolution
- Complementary Tests:
- Immunohistochemical staining for tumor markers and classification if malignancy detected
- Dermoscopy for non-invasive evaluation of pigmented lesions
- Fasting Required?
- Fasting Required: No
- Pre-procedure Preparation:
- No fasting or dietary restrictions required
- Cleanse the biopsy site thoroughly with antiseptic solution 24 hours prior if possible
- Remove any topical medications or ointments from the lesion area 48 hours before biopsy
- Wear comfortable, loose-fitting footwear on day of procedure
- Medications to Avoid:
- Discontinue aspirin and NSAIDs for 5-7 days prior if possible to reduce bleeding risk (consult with physician if on these for medical reasons)
- Avoid anticoagulant medications if not medically contraindicated
- Continue regular essential medications unless specifically directed otherwise by provider
- Additional Patient Instructions:
- Inform provider of any allergies (especially to local anesthetics) prior to procedure
- Discuss all current medications with healthcare provider, particularly anticoagulants or immunosuppressants
- Plan for transportation as there may be temporary discomfort affecting normal walking
- Post-procedure wound care instructions will be provided for proper healing and infection prevention
