We present a case of pemphigus vulgaris which developed during pregnancy. The newborn infant was normal. Bullous lesions were successfully treated by pulse therapy with high-dose corticosteroids. This is, to our knowledge, the first report in English from Japan describing pemphigus vulgaris associated with pregnancy.

Numbers of mast cells were quantitated in the lesions of diffuse scleroderma and morphea. Mast cells increased and then decreased in number in the papillary dermis of diffuse scleroderma. No significant change of mast cell numbers was noted in the reticular dermis. Mast cells increased in the papillary dermis with fine collagen bundles (grade 2 skin of scleroderma) and decreased in the papillary dermis with homogeneous collagen bundles (grade 3 skin of scleroderma). The total number of cells increased in the papillary dermis of grade 1 and 2 skin of scleroderma and decreased in the grade 3 skin of scleroderma. In morphea a reduced number of mast cells was noted in grade 3 lesions. It is suggested that mast cells play an important role in fibrotic process of scleroderma skin.

Liposomes carrying molecules from trinitrophenylated epidermal cells (TNP-EC) liposomes stimulated the hapten-specific proliferation of lymphocytes in vitro in our previous study. In order to analyze the role of TNP-EC liposomes in vivo, they were injected into naive mice. TNP-EC liposomes induced contact sensitivity effectively when injected either s.c. or i.p. Contact sensitivity induced by TNP-EC liposomes was a long-lived T cell-mediated reaction. A s.c. injection of liposomes with molecules from TNP-Ia antigen-depleted epidermal cells [TNP-EC (Ia-) liposomes] failed to induce contact sensitivity and developed unresponsiveness. This unresponsiveness was transferred by T cells, i.e., suppressor T cells. Therefore, it is suggested that Ia antigens in epidermal cells play a critical role for induction and suppression of contact sensitivity.
