INTRODUCTION Paraneoplastic pemphigus (PNP) is considered an autoimmune, multiorgan disease caused by antiplakin antibodies. We present three PNP patients who had negative epithelial direct immunofluorescence (DIF) findings in one or more biopsies. PATIENTS An early lip biopsy of uninvolved oral epithelia in patient 1 was negative. A later biopsy from(More)
BACKGROUND The development of persistent nodules that cause pain and itching at a vaccination or hyposensitization injection site is a rare event. These lesions have been mainly attributed to a hypersensitivity reaction to aluminum hydroxide, which is used as an absorbing agent in many vaccines and hyposensitization preparations. Patch tests with standard(More)
We present a patient with lichen amyloidosus on the ears and macular amyloidosis on the back. These diagnoses were supported by histological, histochemical and immunohistochemical studies. This is to the best of our knowledge the first reported case of a biphasic form of amyloidosis whose lichenoid counterpart consists of papules on the ears. This suggests(More)
A 49-year-old male presented at our department with erythematous brownish plaques in the malar areas and left cheek of 9 years' evolution. Histopathological study revealed a dense, predominantly perivascular, inflammatory infiltrate in the reticular dermis. The infiltrate was composed of abundant neutrophils, lymphocytes, histiocytes, and eosinophils.(More)
Angiomatous lesions appearing in chronic graft versus host disease (cGVHD) has been reported previously. We report a case of a patient in whom cutaneous exuberant granulation tissue developed in the course of a cGVHD after allo-peripheral blood progenitor cells transplantation.
BACKGROUND About 12% of patients with subepidermal autoimmune bullous disease and immunoglobulin G (IgG) at the dermal-epidermal junction present diseases other than bullous pemphigoid. MATERIALS AND METHODS We report the clinical, histopathologic, and therapeutic aspects of eight cases of subepidermal bullous disorder with IgG on the floor of salt-split(More)
Cystic lesions occurring on the ventral surface of the penis have been classified as median raphe cysts of the penis. They are lined by pseudostratified, columnar or stratified squamous cell epithelium, mimicking the epithelial lining of the male urethra. Ciliated cysts of the human skin are unusual. Cystic lesions containing ciliated cells have been noted(More)
