Domain – Dermatological presentations (case)

Lachlan, a 40-year-old male with a past medical history of chronic eczema, presents with a new rash on his lower leg.

Lachlan believes the patches of flaking and scaling have been present for at least a few weeks, but more recently the rash has begun to weep and scab. He asks, ‘Why won’t it heal?’, and is keen for a quick solution to ‘get this fixed, Doc’. His chronic eczema is usually treated with topical steroids. He works full time as an arborist, with inconsistent sun protection. On examination, you observe a Caucasian male with Fitzpatrick type 1 skin. The area in question is faintly erythematous with patches of scaly plaque and a central area of excoriation and light weeping. 

What communications skills would you use to explore Lachlan’s priorities? How would you explore his need for a quick solution?

How would you find out what Lachlan thinks needs to be done to fix his rash?

How would you identify and include Lachlan’s priorities and values into the consultation and treatment plan?

What communication skills would you use if Lachlan had poor English? What if he had a hearing impairment? Or if he had had previous poor experiences with medical institutions?

Arsenic

is a naturally occurring element found in the earth’s crust. It is a metalloid, meaning it has properties of both metals and non-metals. Arsenic exists in several forms, including inorganic arsenic compounds (arsenic trioxide, arsenic pentoxide) and organic arsenic compounds (arsenobetaine, arsenocholine).

Uses of Arsenic

Historical and Industrial Uses

1. Pesticides and Herbicides: Historically used in agriculture to control pests and weeds.
2. Wood Preservatives: Chromated copper arsenate (CCA) was widely used to treat timber, making it resistant to rot and insect damage.
3. Alloys: Used in lead-acid batteries and in combination with other metals to improve strength and corrosion resistance.
4. Glass Manufacturing: Added to glass to remove bubbles and improve transparency.
5. Pharmaceuticals: Used historically in some medicinal preparations.

Current Uses

1. Semiconductor Industry: High-purity arsenic is used in the production of gallium arsenide, a compound used in semiconductors and light-emitting diodes (LEDs).
2. Medical Uses: Arsenic trioxide is used as a chemotherapeutic agent for treating acute promyelocytic leukemia (APL).

Arsenic Use in Australia: The use of arsenic, particularly in pesticides and wood preservatives, has significantly declined due to health and environmental concerns. Australia has regulations restricting the use of arsenic, especially in products that come into direct contact with humans. However, legacy issues remain, especially in areas where arsenic-based products were heavily used.

Acute Arsenic Poisoning

• Symptoms: Nausea, vomiting, abdominal pain, diarrhea, cardiovascular instability, and multi-organ failure.
• Diagnosis: Elevated levels of arsenic in blood, urine, or hair samples.
• Treatment: Immediate removal from the source, supportive care, and chelation therapy (e.g., dimercaprol or succimer).

Chronic Arsenic Exposure

1. Skin Conditions:
   • Arsenical Keratoses: Small, corn-like growths on the palms and soles.
   • Hyperpigmentation: Diffuse or patchy darkening of the skin, particularly on the trunk and extremities.
   • Hypopigmentation: Areas of lighter skin interspersed with hyperpigmentation, often described as “raindrop” pattern
   • Non-Melanoma Skin Cancer: Increased risk of basal cell carcinoma and squamous cell carcinoma, often in areas of sun exposure.
2. Systemic Conditions:
   • Peripheral Neuropathy: Numbness, tingling, and pain in the hands and feet.
   • Cardiovascular Disease: Increased risk of hypertension and vascular disease.
   • Diabetes: Elevated risk of developing type 2 diabetes.
   • Cancer: Increased risk of various cancers, including bladder, lung, and liver cancer.

Key Points

• Arsenic is a naturally occurring element with historical uses in agriculture, wood preservation, and manufacturing.
• Its use has significantly declined due to health concerns, but it is still utilized in the semiconductor industry and specific medical treatments.
• Medical conditions associated with arsenic exposure include acute poisoning, chronic skin conditions like arsenical keratoses, and systemic diseases such as peripheral neuropathy, cardiovascular disease, and various cancers.
• Regulations in Australia have reduced arsenic use, but legacy contamination can still pose health risks.

What types of biopsies may be suitable for Lachlan’s presentation?

How would you approach a rash or lesion in a cosmetically sensitive area; for example, in the middle of the face?

Types of Biopsies Suitable for Lachlan’s Presentation

Given Lachlan’s potential skin conditions, the following types of biopsies may be suitable:

1. Punch Biopsy:
   • Description:
     • A circular tool is used to remove a small, cylindrical core of skin, including the epidermis, dermis, and sometimes subcutaneous tissue.
     • A punch of 3-4 mm is usually sufficient for most conditions.
     • Small diameter biopsies such as 2mm are sometimes used for cosmetically sensitive sites such as the face.
     • A suture may be used to help in wound healing. Generally, the wound is closed with a suture. Sutures on the face can be removed in 5 to 7 days whereas the ones on other areas of the body can be removed in 1 to 2 weeks.
   • Advantages:
     • Provides a full-thickness sample, which is important for accurate diagnosis of many conditions.
     • Better for sampling deeper lesions.
     • Useful for areas
   • Disadvantages:
     • May result in a more noticeable scar, especially if a larger punch (4mm or more) is used.
     • Requires suturing, which may increase the risk of scarring in cosmetically sensitive areas.
   • Indications:
     • ideal for diagnostic purposes as it produces full thickness skin specimens, where deeper tissue analysis is required.
     • Suitable for diagnosing inflammatory skin conditions, infections, and small lesions.
2. Shave Biopsy:
   • Description: A razor-like tool is used to shave off a superficial portion of the skin lesion.
   • Advantages:
     • Minimally invasive.
     • rarely leave a depressed scar.
     • The skin is left to heal by itself without a suture.
     • Quicker healing time.
   • Disadvantages:
     • May not be suitable for deeper lesions, which can lead to incomplete sampling and inadequate depth of the specimen.
     • Not ideal for lesions where full-thickness skin evaluation is necessary.
   • Indications:
     • is most suited for lesions elevated above the skin surface.
     • Suitable for superficial lesions such as actinic keratoses, seborrheic keratoses, and basal cell carcinoma. Not typically used for deeply infiltrative or suspected malignant melanomas.
3. Excisional Biopsy:
   • Description: The entire lesion is removed along with a margin of normal skin.
   • Indications: Preferred for small melanomas, suspected melanomas, and other lesions where a complete removal is diagnostically and therapeutically necessary.
4. Incisional Biopsy:
   • Description: A portion of a larger lesion is removed.
   • Indications: Used when the lesion is too large to remove completely or when a diagnosis is needed before deciding on complete excision.

Approaching a Rash or Lesion in a Cosmetically Sensitive Area

When dealing with a rash or lesion in a cosmetically sensitive area, such as the middle of the face, careful consideration and a tailored approach are necessary:

1. Cosmetic Outcomes:
   • studies have shown that shave biopsies often result in less noticeable scars compared to punch biopsies, particularly in cosmetically sensitive areas such as the face.
   • The minimal invasiveness and lack of suturing with shave biopsies contribute to better cosmetic outcomes .
2. Diagnostic Accuracy:
   • While shave biopsies are adequate for superficial lesions, punch biopsies provide a more comprehensive tissue sample, which is critical for diagnosing conditions that require evaluation of deeper skin layers .
   • For example, when melanoma is suspected, a punch biopsy is preferred due to the need for full-thickness skin assessment .
3. Healing and Complications:
   • Shave biopsies generally heal faster and with fewer complications than punch biopsies.
   • However, if a deep or complete tissue sample is required, the punch biopsy may be necessary despite the potential for a more noticeable scar .
4. Specialized Techniques for Cosmetically Sensitive Areas:
   • Mohs Micrographic Surgery: This technique is particularly suitable for removing skin cancers in cosmetically sensitive areas. It involves the stepwise removal and immediate microscopic examination of thin layers of tissue until only cancer-free tissue remains.
   • Shave Biopsy with Care: For superficial lesions, a carefully performed shave biopsy can be used, but this should be done by an experienced practitioner to minimize scarring.
5. Expert Consultation:
   • Dermatology Referral: Consider referring Lachlan to a dermatologist for lesions in highly visible or cosmetically sensitive areas, especially if malignancy is suspected.
   • Plastic Surgery Consultation: For larger or more complex lesions, involving a plastic surgeon may be beneficial to ensure optimal cosmetic outcomes.
6. Patient Communication and Consent:
   • Detailed Explanation: Explain the procedure, potential risks, and expected cosmetic outcomes to the patient. Emphasize the importance of biopsy for accurate diagnosis.
   • Informed Consent: Obtain informed consent, ensuring the patient understands the potential for scarring and the steps that will be taken to minimize it.
7. Post-Procedure Care:
   • Wound Care: Provide detailed instructions on wound care to promote healing and minimize scarring. This may include keeping the area clean, applying prescribed ointments, and protecting it from the sun.
   • Follow-Up: Schedule follow-up appointments to monitor healing and address any cosmetic concerns that may arise.

Case Example

Scenario: Lachlan has a suspicious lesion on his nose that requires biopsy.

1. Initial Steps:
   • Use dermoscopy to assess the lesion.
   • Discuss with Lachlan the need for a biopsy to confirm the diagnosis.
2. Biopsy Choice:
   • Opt for a punch biopsy with a small diameter (2-3 mm) to minimize cosmetic impact.
   • Explain the procedure, risks, and benefits to Lachlan and obtain informed consent.
3. Procedure:
   • Perform the punch biopsy with care, ensuring precise technique to minimize tissue damage.
   • Send the biopsy sample for histopathological examination.
4. Post-Procedure:
   • Provide detailed wound care instructions.
   • Schedule a follow-up appointment to review biopsy results and discuss further treatment options if necessary.

By following these steps and utilizing appropriate biopsy techniques, you can effectively manage Lachlan’s skin condition while minimizing cosmetic concerns and ensuring accurate diagnosis and treatment.

What is your threshold to perform a diagnostic biopsy? When might it be appropriate to trial a therapeutic approach, and when might a diagnostic biopsy be more appropriate? What is your approach to unclear biopsy results?

Threshold to Perform a Diagnostic Biopsy

Factors Influencing the Decision to Biopsy

1. Suspicion of Malignancy:
   • Any lesion with clinical features suggestive of skin cancer (e.g., asymmetry, irregular borders, color variation, diameter >6 mm, evolving changes) should be biopsied to rule out malignancy.
   • Examples: Suspicious moles, lesions with rapid growth, non-healing ulcers, or lesions with bleeding.
2. Unclear Diagnosis:
   • When the clinical diagnosis is uncertain and cannot be definitively diagnosed through history and physical examination alone.
   • Examples: Persistent or atypical rashes, unusual presentations of common conditions, or lesions not responding to standard treatments.
3. Failure of Initial Treatment:
   • Lesions or rashes that do not respond to initial therapeutic approaches may warrant a biopsy to identify underlying pathology.
   • Examples: Chronic eczema not improving with topical steroids, persistent infections, or dermatoses unresponsive to treatment.
4. Symptomatic Lesions:
   • Lesions causing significant symptoms such as pain, itching, or functional impairment that require definitive diagnosis for targeted treatment.
   • Examples: Painful nodules, pruritic plaques, or lesions causing cosmetic or functional concerns.
5. Patient Concerns:
   • Patient anxiety or concern about a lesion can also warrant a biopsy to provide reassurance through a definitive diagnosis.

When to Trial a Therapeutic Approach vs. Diagnostic Biopsy

Trial Therapeutic Approach

1. Clinical Diagnosis is Clear:
   • When the diagnosis is relatively certain based on clinical presentation, history, and examination.
   • Examples: Typical cases of eczema, psoriasis, or superficial fungal infections.
2. Mild or Initial Presentation:
   • When the condition is mild, recently developed, and has a clear initial treatment plan.
   • Examples: Mild acne, contact dermatitis, or mild bacterial infections.
3. Non-Suspicious Lesions:
   • Lesions with low suspicion of malignancy and where initial therapeutic management is reasonable.
   • Examples: Seborrheic keratosis, mild actinic keratosis, or small benign-looking nevi.

Perform Diagnostic Biopsy

1. High Suspicion of Malignancy:
   • When clinical features strongly suggest malignancy, a biopsy is necessary for diagnosis and treatment planning.
   • Examples: Lesions with ABCDE criteria for melanoma, suspected squamous or basal cell carcinoma.
2. Unresponsive to Treatment:
   • When lesions do not respond to appropriate initial treatments, a biopsy is needed to rule out other pathologies.
   • Examples: Persistent dermatitis despite appropriate topical steroids, unresolved infections despite antibiotics.
3. Atypical or Unclear Presentations:
   • When the presentation is atypical and the differential diagnosis is broad, a biopsy helps to clarify the diagnosis.
   • Examples: Unusual rashes, nodules with ambiguous characteristics, or systemic symptoms accompanying dermatologic manifestations.

Approach to Unclear Biopsy Results

1. Review and Repeat:
   • Review the clinical presentation and biopsy findings. If necessary, repeat the biopsy, possibly from a different site or with a larger sample.
   • Ensure the biopsy was adequately performed and included representative tissue.
2. Additional Diagnostic Tests:
   • Perform adjunctive diagnostic tests, such as immunohistochemistry, molecular studies, or specialized staining techniques.
   • Examples: Direct immunofluorescence for autoimmune blistering diseases, PCR for viral infections.
3. Multidisciplinary Consultation:
   • Discuss the case with dermatopathologists, dermatologists, or other relevant specialists for additional insights or recommendations.
   • Multidisciplinary tumor boards or case discussions can provide valuable perspectives.
4. Clinical Correlation:
   • Correlate biopsy results with clinical findings. Sometimes, clinical context can clarify ambiguous histological findings.
   • Re-evaluate the patient’s history, physical examination, and any new developments since the initial biopsy.
5. Patient Management:
   • Communicate clearly with the patient about the findings, the uncertainty, and the plan moving forward.
   • Discuss the potential need for further testing, monitoring, or empirical treatment while awaiting further clarification.

Example Case Approach

Scenario: Lachlan has a Persistent Rash with Atypical Features

1. Initial Assessment:
   • Detailed history and physical examination to gather all relevant clinical information.
2. Therapeutic Trial:
   • Initial trial of topical steroids and emollients if the rash appears consistent with eczema. Monitor response.
3. Decision to Biopsy:
   • If the rash persists or exhibits atypical features (e.g., ulceration, rapid changes, systemic symptoms), perform a diagnostic biopsy to rule out other conditions such as malignancy, infections, or autoimmune diseases.
4. Unclear Biopsy Results:
   • If biopsy results are inconclusive, review with dermatopathologists and consider additional biopsies or tests.
   • Correlate findings with clinical presentation and discuss with Lachlan the next steps, including possible repeat biopsy or referral to a specialist.

By carefully assessing the need for a biopsy, balancing therapeutic trials, and effectively managing unclear results, you can provide thorough and patient-centered care for Lachlan’s dermatological concerns.

What if Lachlan’s rash were significantly ulcerated, with palpable ipsilateral inguinal lymph nodes?
