Summary
Corticosteroid injections effectively treat de Quervain
Area of Science:
- Dermatology
- Pain Management
- Musculoskeletal Conditions
Background:
- Corticosteroid injections are a common treatment for de Quervain's tenosynovitis.
- Skin depigmentation is a rare adverse effect of these injections.
Observation:
- A 43-year-old man experienced wrist pain due to de Quervain's tenosynovitis.
- He received triamcinolone and bupivacaine injections, achieving 12 months of pain relief.
- Depigmentation occurred at the injection site one week post-treatment.
Findings:
- The patient achieved complete pain relief from corticosteroid injections.
- A 2 cm x 3 cm area of skin depigmentation developed post-injection.
- The depigmentation resolved spontaneously within 9 months.
Implications:
- Steroid-induced depigmentation, though rare, can impact patients.
- Physicians should discuss this potential adverse outcome with patients.
- Awareness and strategies to minimize depigmentation are crucial for interventional pain physicians.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
