A 61-year-old male patient presented with painless thyroid swelling for 2 years duration. He was clinically euthyroid and his thyroid profile was normal. Ultrasound showed hypo echoic thyroid mass in the right lobe with cystic degeneration. FNAC [ Inflammatory myofibroblastic tumour of thyroid is very rare. Only 18 cases reported so far. Here we report a case of Inflammatory myofibroblastic tumour with its prominent spindle cell (fibrohistiocytic) pattern in a 61-year-old male patient. The dominant histological pattern in our case was myofibroblastic in contrast to prominent lymphoplasmocytic pattern in other previously reported cases. The tumour was strongly positive for vimentin, Anaplastic lymphoma kinase and showed focal positivity for Smooth Muscle Actin. The patient was treated with total thyroidectomy and he is comfortable after surgery.showed gray white firm areas with focal cystic change, diffusely involving the entire thyroid specimen. There was no normal thyroid tissue. Tissue sections were routinely processed and stained with Haematoxylin and Eosin.

Sarcomatoid carcinoma is a rare malignant tumor that has both malignant epithelial and mesenchymal components. We describe a sarcomatoid carcinoma arising in the left renal pelvis of a 49-year-old man. The dominant component of the tumor was chondrosarcomatous, but there were also focal carcinomatous areas. The carcinomatous tumor cells consisted of papillary urothelial carcinoma. Immunohistochemical assay showed that the sarcomatous tumor cells were positive for vimentin and S 100 and negative for cytokeratin. The papillary urothelial carcinoma was positive for cytokeratin and negative for vimentin. The patient underwent neoadjuvant chemotherapy and after downsizing the tumor, radical nephrectomy was performed with excision of the cuff of bladder.
