Coexistence of vitiligo and pemphigus vulgaris in an indian patient

Autoimmune bullous diseases associations

The presence of one autoimmune disorder helps lead to the discovery of other autoimmune conditions. It is thought that diseases in which autoimmunity is a feature tend to be associated together more often than one can ascribe to chance. A variety of diseases have been implicated in the onset of intraepidermal and subepidermal autoimmune diseases. The presence of one autoimmune disease should alert the physician to watch for a second immunologic disorder. A list of autoimmune bullous diseases associations includes autoimmune bullous diseases, pemphigus, pemphigoid, epidermolysis bullosa acquisita, dermatitis herpetiformis (Duhring), linear immunoglobulin A disease, and multiple autoimmune syndrome.

A case of concurrent vitiligo and psoriasis

Vitiligo and psoriasis are common dermatoses that occur in 1~3% and 0.5% of the general population, respectively. There have been several reports of the concurrence of these diseases in the English medical literature. Yet the pathogenesis of the association between these two dermatoses is still unknown. Psoriasis may occur coincidentally with vitiligo and it may be strictly confined to the vitiliginous patches or it may occur elsewhere. Despite the reports in the English literature, there has been only one case of vitiligo and psoriasis coexisting in the same patient and these diseases occurred in separate sites in the Korean dermatologic literature. A 30-year-old man recently presented with spreading vitiligo on the right forearm and a 3-month history of guttate psoriasis on the left forearm. He had a family history of psoriasis without any history of associated autoimmune disease. Herein, we report on a case of coexisting vitiligo and psoriasis in the same individual at different sites and we review the relevant literature.

Development of pemphigus vulgaris in a patient with vitiligo and Hashimoto's thyroiditis

Pemphigus vulgaris is an autoimmune blistering disease. An association of pemphigus vulgaris with vitiligo or Hashimoto's thyroiditis has not been reported before. We reported a 38 yr-old female patient with Hashimoto's thyroiditis and vitiligo who eventually developed pemphigus vulgaris on vitiliginous lesions. A genetic predisposition or a local event on vitiliginous skin may be responsible for the development of pemphigus in this patient.
