TRUCCO, L et al. Linear atrophoderma of Moulin. Rev. argent. dermatol. [online]. 2019, vol.100, n.3, pp.93-100.  Epub Sep 30, 2019. ISSN 1851-300X.

It is a disease not very frequent, described in 1992 by Moulin, which occurs between 6 and 20 years of age, characterized by hyperpigmented atrophic bands distribution blaschokoide, mainly located in trunk, unilateral, that are not preceded by inflammation or changes sclerodermal, induration, or adhesions to deep. It is a self-limited condition, whose treatments are ineffective.

We present the case of a boy, 12 years old, with atrophic, hyperpigmented and asymptomatic plates, distributed from the left mammary region to the homolateral back, following the lines of Blaschko. Refers that is started as a hyperpigmented macula and in recent years it has been atrophying, it is not accompanied by any symptomatology, and was not preceded by inflammatory.

We performed laboratory test with complete blood count, renal function, liver function and antibody titers, which were normal; and incisional biopsy by punch, that reported, for a sample stained with hematoxylin-eosin, epidermis of variable thickness, canned, no cellular atypia or disorders madurativos. Dermis impresses discreetly thickened, with homogenization of collagen. Slight perivascular inflammatory infiltrate.

With clinical and anatomopathology we arrive at the diagnosis of Linear atrophoderma of Moulin.
