Bowenoid Papulosis of the Vulva and Subsequent Periungual Bowen's Disease Induced by the Same Mucosal HPVs.

We report the case of a 23-year-old woman who developed bowenoid papulosis of the vulva and subsequent periungual Bowen's disease. She had a history of a long standing periungual wart on her right thumb before the outbreak of periungual Bowen's disease. By HPV DNA chip, human papillomavirus (HPV) 11, 18 and 31 were identified from the periungual lesions, and HPV 11, 18 and 33 from the vulvar lesion.

Recurrent basal cell carcinoma following ablative laser procedures.

Background: In Korea, many patients diagnosed with basal cell carcinoma (BCC) have a history of laser ablations of undiagnosed lesions.

Objective: To evaluate the clinical/pathological and surgical features of BCC developing from undiagnosed lesions following laser ablations (not full-face cosmetic ablations) and to compare them with primary BCCs.

Methods: This study enrolled 359 patients with 373 biopsy-proven BCC lesions.

Oral zinc sulfate treatment for viral warts: an open-label study.

Viral warts, which are caused by the human papilloma virus, are a common problem in dermatology. Various modalities have been used to treat warts, but none are uniformly effective or directly antiviral. Recent studies show that oral zinc sulfate could be effective in the treatment of viral warts.

Oral hairy leukoplakia which occurred as a presenting sign of acute myeloid leukemia in a child.

Oral hairy leukoplakia (OHL) is caused by the reactivation of a previous Epstein-Barr virus (EBV) infection in the epithelium of the tongue. Most lesions are characterized by corrugated whitish patches on the lateral border of the tongue. It is frequently associated with AIDS, but cases in patients with other immunosuppressed states have also been reported.

Angiomyxolipoma (vascular myxolipoma) of subcutaneous tissue.

Lipoma is the most common neoplasm of mesenchyme, and several subtypes have been described that vary according to their location and the presence of other tissue elements. Angiomyxolipoma is a very rare variant that consists of an admixture of adipose and myxoid elements with numerous vascular structures. It should be differentiated from other subtypes of benign and malignant lipomas.

Two cases of pyodermatitis-pyostomatitis vegetans.

Pyodermatitis-pyostomatitis vegetans (PPV) is a rare chronic pustular and vegetating mucocutaneous dermatosis. The oral lesions present as multiple, friable and yellowish pustules, which form "snail tracts" and rupture easily. The cutaneous lesions begin as crusted erythematous papulopustules that coalesce to form large vegetating plaques, usually in the axillae, genital area and scalp.

Endovenous laser surgery of the incompetent greater saphenous vein with a 980-nm diode laser.

Background: In recent years, the minimal endoluminal invasive alternatives against surgical ligation and stripping for the treatment of incompetent greater saphenous vein (GSV) have been explored. Endovenous laser surgery is one of these endoluminal alternatives, and its clinical results are being reported at up to 3 years.

Objective: To evaluate the safety and efficacy of a 980-nm diode laser for the elimination of the incompetent GSV.
