Linear Atrophoderma of Moulin: A Rare Blaschkoid Dermatosis

Year: 2025

Type: article

Abstract: Linear atrophoderma of Moulin (LAM) is a rare, benign dermatosis characterized by unilateral, hyperpigmented, slightly atrophic plaques distributed along Blaschko’s lines. We report the case of an 18-year-old woman with a four-year history of asymptomatic lesions on the right abdomen, thigh, and foot. Histopathology revealed basal layer hyperpigmentation, mild collagen thickening, and a sparse perivascular lymphocytic infiltrate, without sclerosis. The clinical and histological findings confirmed the diagnosis of LAM. Given the stable course and absence of symptoms, a conservative approach with follow-up was adopted. This case underscores the importance of recognizing LAM’s distinctive presentation to avoid unnecessary treatments.
