Reticulate hyperpigmented scleroderma: a new pigmentary manifestation.

Area of Science:

• Dermatology
• Systemic Autoimmune Diseases

Background:

• Scleroderma presents with diverse skin issues, including pigmentary changes.
• Well-documented pigmentary disturbances include generalized hyperpigmentation and localized hypopigmentation with perifollicular hyperpigmentation.
• Vascular-induced hyperpigmentation is a recently recognized manifestation.

Observation:

• A 48-year-old patient with scleroderma exhibited a unique reticulate hyperpigmentation.
• This pattern affected the trunk, upper, and lower limbs.

Findings:

• The patient presented with a previously undescribed cutaneous hyperpigmented reticulate pattern associated with scleroderma.
• This finding expands the spectrum of known pigmentary abnormalities in scleroderma.

Implications:

• Recognizing this new pattern is crucial for accurate scleroderma diagnosis and management.
• Further research is needed to understand the pathogenesis of this specific pigmentary change in scleroderma.
