Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus (LP) that manifests as macular hyperpigmentation involving chiefly the face and upper limbs. Although its etiology has not been fully elucidated, a relationship with hepatitis C infection, restrictive underwear, localized friction, and sun exposure have been proposed. Rarely, exposure to mustard oil, amla oil, henna, or hair dyes has been reported.
Conclusion:
We herein describe an LPP-like reaction to Guasha.
