This is a FNA I did it yesterday. The patient is 70-year-old man and has a malignant tumor diagnosed in 2001. Now has a 1.5cm left chest wall subcutaneous nodule. What's your diagnosis? What's his previous malignancy?
This should be a easy one.

chondrosarcoma (软骨肉瘤)

Most people got this one right. The patient has a history of chondrosarcoma (软骨肉瘤) and now, this is recurrent/metastatic chondrosarcoma. Just want to bring your guys attention on the diff-quick stain, which really highlights the matrix of matrix producing tumors, in this case, the rich myxoid chondroid matrix. the only time I saw a tumor other than chondrosarcoma with this much chondroid matrix was a chondroid chordoma, which is very rare. FNA of chondrosarcoma is usually easy, you see one, you will remember.

| 以下是引用陈隆文博士在2008-12-10 6:42:00的发言： Most people got this one right. 好多人都诊断对了，The patient has a history of chondrosarcoma (软骨肉瘤) and now, this is recurrent/metastatic chondrosarcoma. 患者有软骨肉瘤的病史，这是复发转移的软骨肉瘤，Just want to bring your guys attention on the diff-quick stain,让咱们大家熟悉diff-quick快速染色， which really highlights the matrix of matrix producing tumors, in this case, the rich myxoid chondroid matrix.本例用这种染色特别容易认识肿瘤产生的基质，本例肿瘤就是富于粘液样软骨基质。 the only time I saw a tumor other than chondrosarcoma with this much chondroid matrix was a chondroid chordoma, which is very rare.这也是我第一次看到软骨肉瘤产生这么丰富的软骨基质，也是非常罕见的。 FNA of chondrosarcoma is usually easy, you see one, you will remember.针吸活检确诊软骨肉瘤通常比较容易，你看一次不会忘记。 |
