Linear cutaneous lupus erythematosus is an exceptionally rare variant of cutaneous lupus erythematosus (CLE) characterized by linear erythematous plaques along the lines of Blaschko. This case report describes a unique presentation of linear pigmented discoid lupus erythematosus (DLE) in a 52-year-old, male, Filipino with a history of intense sun exposure. The patient presented with a progressive hyperpigmented linear plaque on the left frontal and left parietal area, without systemic symptoms. The patient demonstrated improvement following a treatment of super high potency topical corticosteroid then topical calcineurin inhibitor with strict photoprotection, and adjunctive measures. The lesions decreased in thickness, hyperpigmentation, and scaling. The Cutaneous Lupus Erythematosus Disease Area and Severity Index showed a decrease in the activity score from six to two, indicating a positive treatment response. Hyperpigmentation of the plaques decreased after two treatment sessions and showed further improvement at one-year follow-up. This is the first reported case of linear DLE on the scalp among local journals in the Philippines, highlighting the importance of considering CLE in the differential diagnosis of linear hyperpigmented plaques, even in the absence of systemic symptoms. This is also the first known case to use pico laser as treatment for DLE, based from our knowledge and from published literature.
