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.

We concluded that vitamin B 12 deficiency may be an aetiological factor in recurrent aphthous stomatitis.

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.
