多处原发性皮肤癌病患比起一般皮肤癌患者，有更高的机会发生次发性皮肤癌，且源於疤痕或慢性砷中毒的扁平上皮细胞癌，其侵袭性、复发率、转移可能性，及并发其他疾病的可能性也比源於紫外线暴露者为高。

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

结果表明，斑点叉尾鮰鳃的表面结构和微细结构与其他硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的扁平上皮细胞所覆盖，鳃弓表面细胞之间有孔洞；鳃耙基部较粗壮；中部鳃丝上皮细胞表面的微嵴两侧有细小的横突，有些微嵴出现融合或间断；端部和基部鳃丝上皮细胞表面的微嵴消失，形成密集颗粒状突起；鳃小片的高度和片间距较大。
