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 document reports a case of systemic lupus erythematosus (SLE) presenting with 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, manifests as erythematous papules with porcelain white atrophic lesions. The case highlights the overlap between Degos disease and cutaneous lupus erythematosus, emphasizing the role of dermoscopy in diagnosis. The patient showed a dramatic clinical and dermoscopic response to treatment, underscoring the importance of recognizing and managing these overlapping conditions.
