We describe a distinctive tissue artifact that results from the use of biopsy bags for processing small impressionable pieces of tissue. In its fully developed form, the artifact produces a tic-tac-toe pattern, while in less pronounced cases it may produce elongated oval spaces in the tissue or a serrated contour at the periphery of the tissue. The artifact was observed in 60% of endometrial specimens, 55% of endocervical curettings, and sporadically in other small specimens. In the endometrial and endocervical specimens, the artifact was focal and did not interfere with the diagnosis. In occasional small lung and prostate specimens, there was focally significant distortion that potentially could compromise the diagnosis.
我们描述了一种独特的组织假象，它是由于使用活检袋处理小块易变形组织而产生的。在其完全发展的形式中，该假象会产生一种井字棋图案，而在不太明显的情况下，它可能会在组织中产生细长的椭圆形间隙或在组织周边产生锯齿状轮廓。在60%的子宫内膜标本、55%的宫颈刮除标本以及偶尔在其他小标本中观察到了这种假象。在子宫内膜和宫颈标本中，该假象是局灶性的，并不影响诊断。在偶尔的小肺和前列腺标本中，存在局灶性的显著变形，这可能会影响诊断。
