Co-existence of Lichen Sclerosus et Atrophicus and Morphoea Along Lines of Blaschko

Extragenital Lichen Sclerosus et Atrophicus

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory dermatosis with anogenital and extragenital presentations. Extragenital lichen sclerosus is most common on the neck, shoulders and upper trunk. Linear lesions are uncommon in LSA. We report a case of linear extragenital LSA involving forehead and scalp, along with grouped white papules of LSA in the right side of the back in a postmenopausal woman. The patient showed atypical clinical presentation of LSA in face which clinically mimicked ‘en coup de sabre’ as seen in morphea, but other clinical features suggested the diagnosis of LSA and the histopathological findings confirmed it.

A Case of Lichen Sclerosus et Atrophicus With Distinct Erythematous Borders

BACKGROUND

Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory and fibrosing condition that mostly affects the genital mucosa. Nongenital skin may be affected either in isolation or in association with genital involvement. A distinct, brightly red border may be seen but is poorly documented in major dermatology texts. In the case presented, such a border was noted in all of the patient's very extensive lesions.

OBJECTIVE

To draw attention to this clinical manifestation and to stimulate future observations as to its clinical and prognostic significance.

METHODS AND RESULTS

A 67-year-old woman presented with disseminated LSA with genital involvement. All the lesions had a distinct red border. A review of major textbooks available to the authors revealed that the presence of a marginal erythema is regularly not mentioned.

CONCLUSION

An erythematous border to LSA may be a notable feature. Its frequency and clinical significance remain to be determined.

Linear cutaneous lupus erythematosus with calcinosis cutis and milia

Linear cutaneous lupus erythematosus (LCLE) is an unusual manifestation of cutaneous lupus erythematosus in which erythematous, atrophic, dyschromic lesions are located along the lines of Blaschko. Calcinosis cutis and secondary milia are very uncommon in lupus erythematosus. We present a rare case of LCLE with calcinosis cutis and milia.
