ABSTRACT
BACKGROUND: Marginal alopecia presents itself frequently in dermatological practice. For patients who present peripheral scalp hair loss, cicatricial and non-cicatricial alopecia should be considered, such as ophiasis, traction alopecia and frontal fibrosing alopecia. In spite of the several types of hair loss that have been described in cutaneous lupus erythematosus, the 'pseudo-fringe sign' had never been observed in such patents. OBJECTIVE: This study aims at including the 'pseudo-fringe sign' as another possibility of clinical manifestation in patients with cutaneous lupus erythematosus. METHODS: A case report of a 67-year-old lady with the diagnosis of lupus erythematosus and peripheral hair loss is shown in this study; the respective differential diagnosis have also been discussed. RESULTS: The diagnosis of a scarring alopecia caused by lupus erythematosus was established with dermoscopy and histopathology. CONCLUSION: Cutaneous lupus erythematosus is another diagnostic possibility for patients who display the 'pseudo-fringe sign'.
