What clinical perspective helps improve diagnostic accuracy for lichen sclerosus across skin tones?
A helpful way clinicians improve diagnostic accuracy for lichen sclerosus across different skin tones is by shifting the focus away from pigment changes alone and instead paying close attention to structural changes of the vulva. Dr. Sameena Rahman talks about this in the introduction chapter of her video on lichen sclerosus, where she explains that most medical atlases only show very light skin, which means hypopigmentation tends to be overemphasized even though it may look very different or be subtle on darker skin. You can watch that segment here.
She highlights that looking for changes in the architecture of the vulva, like thickening of the skin, fissures, regression or loss of the labia minora, and changes in the clitoral hood, is often much more reliable than relying on color alone. She also stresses how often women of color are misdiagnosed with conditions like vitiligo because pigment changes are interpreted without considering these other signs.
Biopsy also matters. Dr. Rahman explains that even a small punch biopsy can confirm the diagnosis and rule out precancerous changes, which is important since lichen sclerosus can sometimes progress to vulvar cancer if left untreated.
