血管萎缩性皮肤异色病1例 总被引:1,自引:0,他引:1
患者女,49岁。颈项、躯干、四肢色素沉着斑15年,逐渐加重2年。患者皮损组织病理示:表皮角化过度,部分棘层变薄,基底细胞液化。真皮浅层血管周围大量淋巴细胞、较多噬色素细胞浸润。根据患者的皮损、组织病理特点及其他相关检查诊断为血管萎缩性皮肤异色病。血管萎缩性皮肤异色病少见,本文对近年来相关文献进行了复习。 相似文献

Tissue from twenty-five patients with mycosis fungoides and three patients with poikiloderma atrophicans vasculare was examined ultrastructurally. Characteristic abnormal lymphoid cells were conspicuous in all biopsies comprising 30–60% of the cutaneous infiltrate. These cells possessed irregular nuclear outlines presenting a spectrum from mild indentation to grossly cerebriform shapes. The other prominent cell type was the histiocyte which occasionally appeared abnormal. Bizarre histiocytic cells resembling the interdigitating reticulum cell of lymph node T cell areas were also observed. In the epidermal infiltrate, abnormal lymphoid cells were seen singly infiltrating between keratinocytes and less frequently in groups, forming Pautrier microabscesses, or in close apposition to histiocytes. Langerhans cells appeared in normal numbers and were usually isolated but were occasionally seen in contact with lymphoid cells. 相似文献

A 46-year-old Negro man with poikiloderma vasculare atrophicans is described. The disease progressed graduall.y for 22 years, with lesions appearing over the neck, trunk and extremities in an asymmetrical distribution, but it did not become lymphoma or collagen disease. Treatment did not appear to influence the course of the disease. 相似文献
