Abstract
Background: Lichen sclerosus et atrophicus (LSA) is an inflammatory dermatitis of unknown etiology affecting usually genital region with rare involvement of extragenital regions like face, neck, shoulder etc. Coexistence of lichen sclerosus et atrophicus and morphea is a very rare finding. Although LSA at early stage and morphea can be differentiated clinically and histologically, both diseases at late stage present diagnostic difficulties.Case presentation: We reported a 4-year-old female child presented with a non-pruritic hypopigmented sclerotic patch over left shoulder. Histopathology showed features consistent with both LSA and morphea in the same lesion.Conclusion: Coexistence of both LSA and morphea in same patient suggests that these lesions represent a spectrum of diseases which may reflect similar events or closely related pathologic process.Bangladesh Journal of Medical Science Vol.15(1) 2016 p.145-147
Highlights
Lichen sclerosus et atrophicus (LSA) consists of flattened white macules which tend to coalesce to form white patches[1]
We report a rare case of extragenital LSA along with morphea in a single lesion of a patient with some peculiar presentations
Case report: We report a case of 4 year old female presenting with a linear non pruritic, slightly indurated hypopigmented to depigmented sclerotic patch over left shoulder gradually enlarging and extending to involve index finger
Summary
Lichen sclerosus et atrophicus (LSA) consists of flattened white macules which tend to coalesce to form white patches[1]. The lesion consists of pronounced edema and homogenization of collagen in the upper dermis 3. On the other hand morphea is characterized by a circumscribed, sclerotic plaque with an ivory coloured centre and histologically by sclerosed collagen bundles in the dermis[4].
