type of lymphocyte infiltration near urothelial carcinoma is diagnostic for chronic lymphocytic leukemia

T-lymphocytic infiltration near the tumor site is an expected immune response in bladder cancers. However, reports of patients with bladder cancer exhibiting small lymphocytic infiltration of the bladder tissue are very rare in the literature. Here, the patient was presented to our group with hematuria, but subsequently diagnosed as exhibiting invasive bladder cancer and chronic lymphocytic leukemia with suspicious lymphocytic infiltration in a transurethral resection specimen. This case emphasizes the importance of lymphocytic infiltration's nature near urothelial carcinoma

Malignant Myoepithelioma of the Palate: A Case Report with Review of the Clinicopathological Characteristics

A malignant myoepithelioma is one of the rarest salivary gland neoplasms which may either arise de novo or develop within a preexisting pleomorphic adenoma or benign myoepithelioma. The parotid gland is the most common primary site and the palate the most common intra-oral site of occurrence. Herein is present a case of a malignant myoepithelioma arising in the hard palate of a 79-year-old woman. The lesion had been examined by biopsy at another hospital, and diagnosed as a poorly differentiated squamous cell carcinoma. The patient underwent a wide local tumor resection. Examination of the resection specimen showed the characteristic histopathological and immunohistochemical features of a malignant myoepithelioma. Five months after the operation, the patient was well without evidence of recurrence or metastasis.
