摘要

泛红间皮增生通常发生在骨盆、腹部或胸部,伴有潜在的肿瘤或炎症过程。这些病变具有临床意义,因为它们可以模拟肿瘤。早期的报告发表于20世纪70年代,但只有少数病例系列的这种病变已发表在妇科病理文献。在此,我们报告一例具有浸润性生长模式的红润间皮增生,模拟浸润性癌。该病变与子宫内膜异位症有关,在腹壁形成肿块。组织学上,间皮细胞的管状排列和巢状排列,其中一些有人造的狭缝样间隙,在子宫内膜腺体和间质附近形成星状病变。细胞异型性轻微,反应性强,calretinin、WT-1和细胞角蛋白5免疫染色阳性,病变为间皮性良性。我们将详细描述本病例的组织学表现,并回顾相关文献。我们讨论了这个诊断陷阱的临床重要性,以及达到正确诊断的途径。

Florid Mesothelial Hyperplasia Associated with Abdominal Wall Endometriosis Mimicking Invasive Carcinoma.

Florid mesothelial hyperplasia typically occurs in the pelvis, abdomen, or chest associated with an underlying neoplastic or inflammatory process. These lesions are of clinical significance because they can mimic a neoplasm. Early reports were published in the 1970s, but only a few case series of such lesions have been published in the gynecologic pathology literature. Here, we report a case of florid mesothelial hyperplasia with an infiltrative growth pattern, mimicking an invasive carcinoma. The lesion was associated with endometriosis forming a mass lesion in the abdominal wall. Histologically, tubular arrangements and nests of mesothelial cells, some with artifactual slit-like spaces, formed a stellate lesion adjacent to endometrial glands and stroma. Cytologic atypia was mild and reactive, and positive immunostaining for calretinin, WT-1, and cytokeratin 5 identified the lesion as mesothelial and benign. We describe in detail the histologic findings in this case and review the pertinent literature. We discuss the clinically importance of this diagnostic pitfall and the path to arriving at the correct diagnosis.
