A secondary discoid lupus erythematosus induced by scald of edible oil: An illustration of Koebner phenomenon.

BACKGROUND

Discoid lupus erythematosus (DLE) is a most well-known clinical variation of chronic cutaneous lupus erythematosus inside the spectrum of lupus erythematosus (LE). Cutaneous trauma remains a significant and peculiar causative factor for DLE.

AIMS

We present a case wherein the patient demonstrated unilateral distribution of DLE on a clinically normal appearing occult facial scald of edible oil, representing Koebner phenomenon (KP) i.e. occurrence of a new skin disease at the site of an unrelated and already healed one.

PATIENT/METHODS: The 53 years old female patient was unique because she experienced DLE on the nasal back.

RESULTS

The injury was totally settled following a month treatment of oral hydroxychloroquine and topical 0.03% tacrolimus ointment. After three months, she encountered an accidental edible oil scald on the right upper cheek. Several small vesicles appeared on a soybean-sized erythema base with a burning sensation.

CONCLUSION

We review the literature and conclude by discussing important histologic highlights to think about while endeavoring to perceive the fundamental character and pathogenicity of such sores.
