Cantharidin

Treatments and Common Skin Conditions

Cantharidin

This solution contains a derivative of beetle venom. It is commonly used to treat molluscum contagiosum because it is painless upon application and destroys the lesions by forming a blister beneath the wart, separating it from its blood supply. This prompts the body to recognize the virus, and the immune system begins to fight it.

Side Effects:

• Blisters
• Redness
• Pain (may occur after blister formation)
• Bleeding (infrequent, may occur if the blister ruptures)

Important Considerations:

• Application should be performed by a healthcare professional.
• Do not attempt to apply cantharidin at home.
• It is important to follow the professional's instructions for post-application care.

Wound Healing

Contrary to popular belief, wounds heal much better in a moist environment. This ensures that the wound heals correctly from the inside out, leaving the smallest possible scar.

Wound Care Instructions:

• Wash the wound twice daily with soap and water.
• Use a mild, fragrance-free soap for sensitive skin, such as “Dove Sensitive Skin” or similar.
• Apply a thin layer of petroleum jelly (Vaseline) or an antibiotic ointment (if recommended by a doctor) to the wound.
• Keep the wound covered with a clean bandage at all times until it is completely healed.
• After the wound has healed, it is recommended that the patient apply sunscreen to the scar to minimize its appearance and prevent hyperpigmentation.

These instructions apply to:

• Shave biopsies
• Punch biopsies
• Destruction of skin lesions such as warts, keratoses, solar lentigos (age spots), skin tags, and surgical incisions.

Common Conditions: Seborrheic Dermatitis

Seborrheic dermatitis, commonly known as dandruff, is a chronic, inflammatory, and quite common condition. It causes white to yellowish scales to form on oily areas such as the scalp, eyebrows, around the nose, and/or inside the ear.

Symptoms:

• Redness
• Inflammation in the affected area
• Itching (pruritus)
• Burning sensation
• Scaling/dryness

Additional Information on Seborrheic Dermatitis:

• It mainly affects areas with a high concentration of sebaceous glands.
• It can worsen with stress, cold and dry weather, and the use of certain hair care products.
• Treatment usually includes antifungal shampoos and creams, topical corticosteroids, and other medications depending on the severity of the case. It is important to consult a dermatologist for proper diagnosis and treatment.
