早期梅毒皮损形成机制的研究

目的 探讨形成早期梅毒皮损的可能机制。方法 分别用常规病理、银染及免疫组化法检测30例早期梅毒皮损组织中的病理变化、梅毒螺旋体和Th1/Th2细胞因子的表达。结果 一期梅毒硬下疳和二期梅毒的结节、斑块、丘疹、脓疱等皮损中有典型的梅毒组织学结构和梅毒螺旋体,而斑疹损害中无典型的梅毒组织学结构和梅毒螺旋体。硬下疳中Th1型细胞因子表达占优势,二期梅毒患者的结节、斑块、丘疹、脓疱等皮损中Th1/Th2型细胞因子的表达视梅毒螺旋体感染时间长短而不同,Th2型细胞因子的表达主要见于感染时间较长的皮损,而斑疹中Th2型细胞因子表达与梅毒螺旋体的感染时间无关。结论 二期梅毒斑疹损害可能因机体的变态反应引起。     

Human papillomavirus infection of the oral mucosa.

This article reviews the lesions of oral mucosa that contain human papillomavirus (HPV). These HPV-associated lesions can be classified into two broad types on the basis of their biologic behavior, benign lesions and premalignant malignant or malignant lesions. Benign oral lesions include squamous cell papilloma (SCP), verruca vulgaris (VV), condyloma acuminatum (CA), and focal epithelial hyperplasia (FEH). Of these entities, VV, CA, and FEH demonstrate characteristic HPV-induced cytopathic effects, whereas SCP infrequently shows such changes. All of these lesions show a clear association with HPV. Premalignant and malignant oral lesions include leukoplakia and squamous cell carcinoma. The etiologic role of HPV in these lesions is still unclear. Koilocytosis is the most common cytopathic effect seen in both groups of lesions. Even though it is sometimes difficult to distinguish between hyperplastic lesions such as SCP, VV, and CA, clinical and certain histologic features can facilitate the diagnosis. Although exceptions do exist, each of the two classes of lesions is most commonly associated with particular HPV types. The benign oral lesions are associated with HPV 2, 4, 6, 11, 13, and 32; the malignant oral lesions are associated with HPV 16 and 18. No preferential association has been demonstrated between specific HPV types and a particular oral lesion.     

Dermoscopic patterns of benign volar melanocytic lesions in patients with atypical mole syndrome

BACKGROUND: Acral benign melanocytic lesions in white populations, particularly in subjects with atypical mole syndrome, have been poorly characterized until recently. The advent of dermoscopy has enabled more specific diagnoses of these pigmented skin lesions. OBJECTIVE: To evaluate the clinical and dermoscopic features of benign volar lesions in a group of white patients with atypical mole syndrome. SETTING: A private medical center specializing in early diagnosis of malignant melanoma and a melanoma unit in a university hospital. METHODS: Acral melanocytic lesions in 511 patients with atypical mole syndrome were studied using standard clinical assessment and dermoscopy. RESULTS: Two hundred ten acral melanocytic lesions were observed in 156 of the patients: 165 lesions were present on the soles of 121 patients and 45 lesions on the palms of 35 patients. No acral malignant lesions were detected. We observed the following patterns of lesions: parallel furrow in 111 lesions (52.9%), latticelike in 26 lesions (12.4%), fibrillar or filamentous in 13 lesions (6.2%), and nontypical in 29 lesions (13.8%). In 31 lesions (14.8%), we observed 3 previously undefined patterns: a globular pattern in 11 lesions (5.2%), a homogeneous pattern in 15 lesions (7.1%), and an acral reticular pattern in 5 lesions (2.4%). CONCLUSIONS: We observed a greater number of benign melanocytic lesions in glabrous skin than expected, probably related to our cohort selection of patients with atypical mole syndrome, although the lesions generally exhibited patterns on dermoscopy similar to those seen in Japanese studies. We defined 3 new benign dermoscopic patterns, which will enable better characterization of acral lesions.

Melanocytic aggregation in the skin: diagnostic clues from lentigines to melanoma

Pigmented skin lesions are among the most common skin lesions. Among them, melanocytic proliferations are morphologically diverse and their behavior may be difficult to discern with certainty. Researchers must be able to distinguish melanocytic from nonmelanocytic pigmented skin lesions and, in particular, benign from malignant lesions. The majority of these lesions can be diagnosed with ease; however, a minority of cases is difficult and have potential for error. The authors have systematically analyzed the clinical and dermoscopic features of melanocytic skin lesions, so as to increase in vivo diagnostic accuracy.

Digital image analysis for diagnosis of cutaneous melanoma. Development of a highly effective computer algorithm based on analysis of 837 melanocytic lesions

BACKGROUND: Digital image analysis has been introduced into the diagnosis of skin lesions based on dermoscopic pictures. OBJECTIVES: To develop a computer algorithm for the diagnosis of melanocytic lesions and to compare its diagnostic accuracy with the results of established dermoscopic classification rules. METHODS: In the Department of Dermatology, University of Tuebingen, Germany, 837 melanocytic skin lesions were prospectively imaged by a dermoscopy video system in consecutive patients. Of these lesions, 269 were excised and examined by histopathology: 84 were classified as cutaneous melanomas and 185 as benign melanocytic naevi. The remaining 568 lesions were diagnosed by dermoscopy as benign. Digital image analysis was performed in all 837 benign and malignant melanocytic lesions using 64 different analytical parameters. RESULTS: For lesions imaged completely (diameter < or = 12 mm), three analytical parameters were found to distinguish clearly between benign and malignant lesions, while in incompletely imaged lesions six parameters enabled differentiation. Based on the respective parameters and logistic regression analysis, a diagnostic computer algorithm for melanocytic lesions was developed. Its diagnostic accuracy was 82% for completely imaged and 84% for partially imaged lesions. All 837 melanocytic lesions were classified by established dermoscopic algorithms and the diagnostic accuracy was found to be in the same range (ABCD rule 78%, Menzies' score 83%, seven-point checklist 88%, and seven features for melanoma 81%). CONCLUSIONS: A diagnostic algorithm for digital image analysis of melanocytic lesions can achieve the same range of diagnostic accuracy as the application of dermoscopic classification rules by experts. The present diagnostic algorithm, however, still requires a medical expert who is qualified to recognize cutaneous lesions as being of melanocytic origin.
