Linear Morphea Mimicking Lichen Striatus in Its Early Presentation

Area of Science:

• Dermatology
• Pathophysiology

Background:

• Linear morphea and lichen striatus are typically considered distinct dermatological conditions.
• Previous literature has reported a link between these conditions in only one case.

Observation:

• This report details two cases where facial lichen striatus occurred before the onset of linear morphea.
• Both conditions manifested at the same anatomical site on the face.

Findings:

• The temporal sequence of lichen striatus followed by linear morphea at the identical facial location was observed in both patients.
• This presentation suggests a potential, previously underreported association.

Implications:

• Further research is warranted to explore a possible pathogenic relationship between lichen striatus and linear morphea.
• Understanding this association may improve diagnostic and therapeutic strategies for both conditions.
