- Older women pelvic mesothelioma (cqz2)
When we have a case we must have differential diagnosis. In other words we must think many different possible diagnoses, then order the necessary IHC and rule out others.
You cannot just have a possible dx and order one stain. We as pathologists should consider and analyse questions more widely.

啊呀，好惭愧，我没看清病史，以为是卵巢病变了
盆腔活检，上皮样恶性肿瘤，有乳头结构和砂粒体。主要考虑间皮瘤（上皮样型/蜕膜样型）、腺癌（腹膜原发或转移性）、GIST、蜕膜变。
最近一项研究认为，calretinin和thrombomodulin作为腹膜间皮瘤的阳性标记物，Ber-EP4, MOC-31, CA19-9, ER作为腹膜间皮瘤的阴性标记物，对鉴别腹膜间皮瘤和浆液性腺癌具有相当高的特异性和敏感性。

Abin summaried well. Generally at least two mesothlial markers and two epithelial markers are needed for the differential dx.
Lesson: Always consider the possible differential dx and decide to order the IHC stains.
Final dx: mesothelioma
