“Why Do I Have Dark, Thick Patches on My Skin That Won’t Go Away?”
At Village Dermatology in Katy, Texas and Houston, Texas, patients often come to us with long-standing skin conditions that have not improved with prior treatments. One such case involved a 43-year-old female patient who presented with a chronic rash affecting multiple areas of her body.
Her main concern during the visit was:
“Why do I have dark, thick patches on my skin that won’t go away?”
This is a common question among patients dealing with morphea, a rare but persistent skin condition.
Understanding Generalized Morphea
During the examination, the patient was found to have generalized morphea, a condition she had previously been diagnosed with and treated for using phototherapy and systemic medications.
On exam, she had:
Confluent, bound-down hyperpigmented plaques
Areas of skin thickening (sclerosis)
Lesions distributed across the back, trunk, and breasts
Morphea is a type of localized scleroderma, which causes:
Hardening and thickening of the skin
Changes in pigmentation
Long-lasting plaques that may persist for years
Unlike systemic scleroderma, morphea typically does not affect internal organs, which is reassuring for many patients.
Why Morphea Can Be Difficult to Treat
Morphea can be challenging because:
It is chronic and long-lasting
Response to treatment can vary significantly
Lesions may improve slowly over time
Some areas may remain permanently changed
Even with treatment, patients may experience periods of progression and stability.
Treatment Options for Morphea
This patient had previously tried:
Methotrexate
Other light-based treatments
Given her ongoing symptoms, we discussed restarting treatment with a structured approach.
Phototherapy (Light Treatment)
Phototherapy is one of the most effective treatments for morphea.
The plan included:
Starting in-office phototherapy sessions
Initiating the process for at-home phototherapy approval
Phototherapy helps by:
Reducing inflammation
Softening thickened skin
Slowing progression of plaques
This treatment is often used long-term to manage symptoms.
Topical Treatments
Patients may also benefit from:
Topical steroids to reduce inflammation
Calcipotriene to help regulate skin cell growth
These treatments can improve the appearance and texture of affected skin.
Photoaging and Skin Health
In addition to morphea, the patient also had photoaging (sun damage) on the face.
Photoaging can cause:
Uneven pigmentation
Fine lines and wrinkles
Thinning of the skin
To address this, we recommended:
Tretinoin Benefits
Tretinoin helps by:
Increasing skin cell turnover
Improving skin texture
Reducing pigmentation and fine lines
Patients should:
Apply a pea-sized amount at night
Start 2–3 times per week
Increase gradually as tolerated
Cosmetic Treatment Considerations
The patient also expressed interest in cosmetic treatments. Given her diagnosis of morphea, we discussed safe options.
Safe Options:
Treatments to Avoid:
Laser resurfacing
These more aggressive treatments may worsen skin changes in patients with morphea.
When to Follow Up
Because morphea can evolve over time, the patient was advised to return in 2–3 months to monitor progress and adjust treatment as needed.
Patients should also contact their dermatologist if:
Lesions spread
Skin becomes more firm or thickened
New areas of involvement appear
