Although lichen planus and vitiligo are common skin disorders, their association with two other uncommon diseases, i.e. lichen sclerosus et atrophicus and disseminated superficial actinic porokeratosis, seems to be a very rare occurrence. We report herein a 70-year-old man who developed all of these four skin disorders simultaneously.

Lichen sclerosus (LS) et atrophicus is a disease of unknown etiology, although hereditary, endocrine, and autoimmune factors are known to be involved. While the anal and genital regions are predominantly affected, only 2.5% of patients present with extragenital lesions, particularly of the trunk, neck, and upper limbs. The possible relationship between lichen sclerosus et atrophicus and both li...

Lichen sclerosus et atrophicus (LSA), also called Lichen sclerosus (LS) is a chronic, benign, depigmenting disease of the skin and mucous membranes, most frequently affecting genital mucosa and skin. Involvement of the oral mucosa without concurrent genital or skin lesions has very rarely been reported in the literature. Here we report on two Chinese women with LSA limited to the dorsum of the ...

Generalized guttate morphea is a very uncommon clinical entity, and few reports are available in the literature. We report the case of a 7-year-old boy who first attended our clinic in 1990 with guttate morphea on the trunk and upper limbs. These lesions were associated with plaque morphea on his right foot. Twelve years later, lesions with a different appearance to the previous ones were obser...
