Microscopically, there are spindle to oblong cells with hyperchromatism and pleomorphism.
顯微鏡下見深染多形性的梭形或橢圓形細胞。
It is much more cellular and the cells have much more pleomorphism and hyperchromatism than the benign leiomyoma.
與良性的平滑肌瘤相比,其細胞豐富,細胞異型性明顯,深染。
At high magnification, the neoplastic glands of adenocarcinoma have crowded nuclei with hyperchromatism and pleomorphism.
高倍鏡下腺癌腺體見大量密集深染異型性明顯的細胞核。
Here is an adrenal cortical carcinoma seen microscopically at high power to demonstrate cellular pleomorphism with nuclear hyperchromatism.
高倍鏡下的腎上腺皮質癌,顯示細胞的多形性、細胞核染色過深。
At high magnification, the neoplastic glands of adenocarcinoma have crowded nuclei with hyperchromatism and pleomorphism. no normal goblet cells are seen.
高倍鏡下腺癌腺體見大量密集深染異型性明顯的細胞核。不見正常的杯狀細胞。
Hyperchromatism(核深染現象)是病理學和細胞學中的專業術語,指細胞核内染色質過度濃縮導緻染色加深的現象。該詞源自希臘語"hyper"(過度)和"chroma"(顔色),主要用于描述細胞異常增殖過程中核染色質的病理改變。
在臨床診斷中,hyperchromatism被視為細胞惡性轉化的重要指标之一。根據《Robbins and Cotran Pathologic Basis of Disease》的病理學原理,這種現象常見于惡性腫瘤細胞,表現為核内DNA含量異常增加及染色質分布紊亂,導緻細胞核在顯微鏡下呈現深藍色或深紫色特征。美國癌症協會(American Cancer Society)指出,這種核形态改變常伴隨核增大和核膜不規則,是巴氏塗片等癌症篩查技術的關鍵判斷依據。
在皮膚病理學領域,《Lever's Histopathology of the Skin》記錄該現象還可見于某些良性病變,如脂溢性角化病的基底細胞層,需結合其他形态特征進行鑒别診斷。世界衛生組織(WHO)的腫瘤分類系統強調,對hyperchromatism的評估應結合核分裂象計數和細胞異型性程度進行綜合判斷。
"hyperchromatism" 是一個醫學術語,主要包含以下含義:
該詞主要用于醫學領域,需結合具體語境理解。若需進一步了解血液學中的具體案例(如高色素性大紅細胞症),可參考臨床醫學文獻或專業詞典。
