A Neglected Case of Systemic Lupus Erythematosus Presenting with Degos' Skin Disease and Diffuse Non-Scarring Alopecia with Dramatic Response to Treatment, Clinically and Dermoscopically

This article presents a case of systemic lupus erythematosus (SLE) manifesting as Degos' skin disease and diffuse non-scarring alopecia. SLE is an autoimmune disease where hair loss is common, affecting 17.3%-85.2% of patients, and can be either scarring or non-scarring. Degos disease, a rare systemic disorder characterized by erythematous papules with porcelain white atrophic centers, can overlap with SLE in clinical and histological features. The reported case involved a patient with Degos disease, non-scarring alopecia, and digital ulcers. The study highlights the use of dermoscopy in diagnosing these conditions and notes a dramatic clinical and dermoscopic improvement following treatment.
