Abstract :
Alopecia areata (AA) is a chronic inflammatory condition that affects the hair follicles and sometimes, the nails. It is believed that AA is caused by T cell-mediated autoimmune response and increased frequency of other autoimmune diseases in persons suffering from AA supports this hypothesis. A 12-year-old boy presented with extensive alopecia areata with pitting in all nails for 6 years. He had developed lesions of vitiligo and lichen planus on trunk in a segmental manner. While the association of alopecia areata and vitiligo as well as lichen planus is well known, segmental nature of both vitiligo and lichen planus is quite rare
