Actinic lichen planus is a clinical variant of lichen planus, involving mainly sun-exposed areas and manifested as annular lesions with a pigmented center surrounded by a hypopigmented zone. A rare presentation of actinic lichen planus mimics melasma but have distinctive histopathologic picture in favour of actinic lichen planus. Herein, we report a 14-year-old boy who presented with a me...

Studies suggest an estimated 0.3-3% risk...

Lichen planus is a T-cell mediated autoimmune disorder affecting the skin and mucous membranes. Ulcerating lichen planus is uncommon mostly on oral and genital mucosa but not skin. Lichen planopilaris, however, is a subtype of lichen planus affection hair follicles and leading to permanent scarring alopecia. We report a case of lichen planopilaris of the scalp with multiple alopecic patches ulc...

This paper reports on our ongoing work regarding opinion mining from Web-based discussion forums in the realm of the Understanding Advertising (UAd) project. Our approach to opinion mining is to first RDFise discussion forums in SIOC, and in a second phase to interlink the so created data with linked datasets such as DBpedia. We are confident that this should allow a market researcher to formul...
