Squamous cell carcinoma Verrucous Verrucous carcinoma is a highly differentiated squamous cell carcinoma that has a hyperkeratotic, undulating, warty surface and invades the underlying stroma in the form of bulbous pegs with a pushing border. The tumous cells have abundant cytoplasm, and their nuclei show minimal atypia. Feathures of HPV infection are not evident. Verrucous carcinomas have a tendency to recur locally after excision but do not metastasize. They are distinguished from condyloma by their broad papillae that lack fibrovascular cores and the absence of koilocytosis. Verrucous carcinoma is distinguished from the more common types of squamous cell carcinoma in that it shows no more than minimal nuclear atypia.(WHO 2003 P267) 首先,疣状癌(verrucous carcinoma)是一种高分化鳞癌。 其次,疣状癌有自己的特点: 1 表面:角化过度,起伏不平,疣状增生。 2 基底:推挤性浸润,上皮脚呈杵状或球茎状。 3 细胞:胞浆丰富,非常轻微的异型性(WHO皮肤图1.17示异型性程度不超过CIN 1级,可参考)。HPV感染的形态学改变(无控空细胞)不明显。 4 炎症:WHO皮肤:“中性粒细胞的出现是重要的诊断线索,可以形成小的表皮内脓肿”。 5 预后:倾向于局部复发,但不转移。WHO皮肤:“长期病例或放化疗后,疾病的生物学特征可以转变为转移性鳞癌”。 6 DD: (1)与湿疣的不同点:乳头又宽又大,无纤维血管轴心。无控空细胞。 (2)与高分化鳞癌的不同点:异型性非常轻微。 (3)疣性癌(warty carcinoma或湿疣状鳞癌condylomatous squamous cell carcinoma)的特点:表面呈湿疣状,有高危型HPV感染的证据。 综上,本例为活检标本,不能全面观察基底情况(等手术标本看到典型表现再报疣状癌也不迟啊),细胞特点不符合,有浸润和转移(临床2期),已不宜诊断为“疣状癌”。如果诊断疣性癌(warty carcinoma),必须有高危型HPV感染的证据。因此,个人认为本例为高分化鳞状细胞癌,可能伴疣状癌(verrucous carcinoma)的部分特征。
