Ultrasound-guided foam sclerotherapy for treating incompetent great saphenous veins--results of 5 years of analysis and morphologic evolvement study.

Background: Varicose veins of the lower leg is a common disease and is associated with long-term morbidity. It has been treated using high ligation with stripping and endovenous laser surgery of the great saphenous vein (GSV).

Objectives: To investigate the clinical outcomes of GSV insufficiency after ultrasound-guided foam sclerotherapy (UGFS) using 3% sodium tetradecyl sulfate (STS).

Extramammary Paget's disease of the unilateral axilla: a review of seven cases in a 20-year experience.

Background: Extramammary Paget's disease (EMPD) is an uncommon malignancy that occurs on apocrine-rich skin. EMPD of the axillary region is extremely rare and is not well documented. Objectives  The aim of the study is to review our experience with axillary EMPD with regard to initial examination, treatment, and long-term outcome.

Ten cases of sebaceous carcinoma arising in nevus sebaceus.

Although nevus sebaceus is known to develop various types of secondary neoplasms, it rarely causes carcinoma and only 14 cases of secondary sebaceous carcinoma have been reported. In this study, 10 cases of sebaceous carcinoma arising in nevus sebaceus were collected. The clinicopathological features and results of immunohistochemical examinations with adipophilin, perilipin and p53 were summarized.

Subungual melanoma: histological examination of 50 cases from early stage to bone invasion.

Subungual melanoma is a rare form of malignant melanoma. It is extremely difficult to differentiate it histologically from benign melanonychia striata or melanocytic nevus, especially in the early stage. We divided 50 cases of subungual melanoma into four groups according to clinical progress, and examined their histological findings in each respective stage.

Sebaceous carcinoma of the eyelids: thirty cases from Japan.

Sebaceous carcinoma of the eyelids is rare in Western countries but not uncommon in Asian countries. Diagnosis is difficult both clinically and histologically. Thirty cases of sebaceous carcinoma of the eyelids treated at Tokyo Medical University Hospital were reviewed to elicit characteristic features of pathological findings.

Cheilitis granulomatosa associated with allergic contact dermatitis to betel quid.

Cheilitis granulomatosa (CG) is a rare disorder of unknown origin, which is characterized clinically by painless, recurrent or persistent swelling of 1 or both lips. Betel quids, composed of betel nuts (seeds of the Areca catechu), slake lime, and Piper betel leaf/or Piper betel inflorescence, are widely used in Asia and strongly associated with oral mucosal disease. It has also been found to be a cause of contact leukomelanosis because of its ingredients of various chemicals.

Treatment of a tufted angioma with intense pulsed light.

Tufted angioma is a rare cutaneous angiomatous proliferation named because of its characteristic histologic pattern of grouped dermal capillary tufts. Lesions usually begin in infancy or early childhood but rarely are congenital. Clinical manifestations are dull red coalescent papules and plaques, most commonly located on the neck, shoulders, and upper back, and can sometimes be tender.

Malignant cutaneous tumors of the scalp: a study of demographic characteristics and histologic distributions of 398 Taiwanese patients.

Background: The scalp is a unique anatomic region, in which pilosebaceous follicles are concentrated.

Objective: We sought to investigate demographic characteristics and histologic distributions of malignant scalp tumors.

Methods: Primary and metastatic scalp malignancies diagnosed histopathologically between 1983 and 2003 were reviewed.
