Dermatitis papulosa juvenilis, also referred to as frictional lichenoid eruption, summertime lichenoid dermatitis of the elbows, Sutton's summer prurigo, recurrent papular eruption of childhood, and sandbox dermatitis, has been reported previously only in children. We describe three cases of DPJ in adults, which were confirmed by clinical and histology investigations. The term 'dermatitis papul...

For many years, amalgam was the preferred repair material; however, because of worries about aesthetics, mercury toxicity, and development lichenoid diseases, its use has decreased. The oral mucosa a reaction known as lesion (OLL). Dental materials, particularly amalgam, medications, graft-versus-host disease (GVHD), are among backgrounds OLL. When restorative most frequently come into close to...

Lichenoid reactions represent a family of lesions with different etiologic factors and a common clinical and histologic ap-pearance. Lichen planus is included with lichenoid reactions and is a relatively common chronic mucocutaneous disorder. The most important complication of lichenoid reactions is the possibility of malignant transformation. That is why it has been considered a precancerous c...

BACKGROUND AND OBJECTIVES Standard or investigative immunosuppressive therapies for cutaneous chronic graft-versus-host disease (GVHD) may prove not only ineffective but also cause serious adverse effects. Repeated exposure of the skin to ultraviolet radiation in the wavelength range 340-400 nm (so-called ultraviolet A1) was recently reported to have a strong local (intracutaneous) immunomodula...

Gianotti-Crosti syndrome (papular acrodermatitis of childhood), which was first described in 1955, is a nonspecific rash that usually consists of the abrupt onset of pink flesh coloring, smooth or lichenoid, flat-topped papules. It was first related to hepatitis B virus (HBV) infection; however, cases not associated with HBV infection were reported as well. Although a type of delayed hypersensi...

Lichen Striatus is an uncommon inflammatory skin eruption of unknown etiology. It rarely affects adults, and it is characterized by abrupt onset of coalescent papules, in a linear disposition, usually on the extremities. Histopathology shows lichenoid reaction involving follicles and glands. Occasionally, there is overlap with linear lichen planus and "blaschkitis", the main differential diagno...
