4 cases with differing presentations of contact allergy to acrylates in sculptured acrylic nails are presented. These reactions include nail fold, fingertip and hand dermatitis, face and neck dermatitis, dystrophic nail changes and paraesthesia. We discuss acrylic nails and review the previously published reactions to acrylates in acrylic nails.

Paraneoplastic pemphigus is a recently described autoimmune disease characterized by painful mucosal ulceration and polymorphous skin lesions in association with an underlying neoplasm. Distinct autoantibodies bind desmoplakin I, desmoplakin II, bullous pemphigoid antigen and an uncharacterized 190 kDa antigen. A case is presented of paraneoplastic pemphigus that developed after radiotherapy for non-Hodgkin's lymphoma in a 53 year old man. Multiple skin biopsies showed a lichenoid reaction without acantholysis. Immunofluorescence and mucosal biopsies were required to establish the correct diagnosis. Corneal opacities resembling lichenoid graft-versus-host disease and retinal haemorrhages, which developed in the patient, have not been previously documented. Despite high doses of immunosuppressive agents and plasmaphoresis, the patient eventually died from respiratory failure.

A case of acute febrile neutrophilic dermatosis (Sweet's syndrome) associated with Behçet's disease occurring in a 48 year old woman is reported. She fulfilled the diagnostic criteria for both Sweet's syndrome and Behçet's disease. There have been several reports of this association. Herpes simplex virus was isolated from a genital ulcer in our patient. The possible role of herpes simplex virus in this interesting association of Behçet's disease and Sweet's syndrome is discussed and a review of the literature is made.
