A predisposition to occlusive vascular diseases has been reported in patients with psoriasis and it has been suggested that some of these patients have some disorders of lipid metabolism. In this study, serum lipid levels were investigated in psoriatic patients to explore to the knowledge of this relationship. One hundred psoriatic patients and 100 non- psoriatic controls were included in the study. Total cholesterol, triglyceride, high-density lipoprotein-cholesterol (HDL-cholesterol), low-density lipoprotein-cholesterol (LDL-cholesterol), and very low-density lipoprotein-cholesterol (VLDL-cholesterol) levels were measured. In patients with psoriasis, total cholesterol and LDL-cholesterol levels were found to be significantly higher than those of controls. No significant differences were found in the other parameters. We concluded that psoriatic patients should be evaluated and followed up for the risk of hyperlipidemia and obstructive vascular diseases.
Although PCR was superior to the Tzanck test, the Tzanck test has also been proven to be a reliable diagnostic method, with a sensitivity of 76.9% and a specificity of 100%. We recommend the use of this easy, quick, reproducible, and inexpensive diagnostic test more often in dermatologic practice, especially in cutaneous herpes virus infections.
Clinical manifestations of benign (reactive) plasma cell proliferations of the skin and mucosa consist of a relatively rare and distinct group in dermatologic disorders. They have generally been named according to their localization. We report a typical case of mucocutaneous plasmacytosis located on intertriginous areas of the skin as well as mucosa with a perianal tumoral mass diagnosed as plasmoacanthoma. To our knowledge, this is the first detailed case report, at least in English literature.
We report a case of amyloidosis cutis dyschromica with diffuse postinflammatory-type hypo- and hyperpigmentation all over the body. The diagnosis was confirmed with routine light microscopic and immunohistochemical staining methods. The patient was treated with acitretin with a good response.
The incidence of tuberculosis and extrapulmonary forms of this disease is increasing all over the world. Lupus vulgaris is the most prevalent form of cutaneous tuberculosis in Europe and the Middle East. Papulonecrotic tuberculid, the most common form of hyperergic response to mycobacteria or their fragments, is uncommon in children. We report lupus vulgaris with papulonecrotic tuberculid in a 12-year-old girl who had a 3-year history of slowly growing plaques on her trunk, extremities, and the tip of her nose and papuloulcerative lesions over her entire body. A skin biopsy specimen showed minimally caseating granulomatous inflammation. Staining for acid-fast bacilli was negative in both plaques and papules. Polymerase chain reaction identified Mycobacterium tuberculosis DNA in the patient's sputum, gastric fluid, and plaques and was negative in the papules. She was started on antituberculous therapy with four drugs and her lesions responded rapidly.
Dermatologists should investigate lipid profile, especially lipoprotein (a), of patients with androgenetic alopecia and refer to a cardiologist if necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
