EP3 Prostate Adenocarcinoma Metastasis to the Bilateral Ureters
Autopsy, Forensic, Grossing 004 Id: EP3 Prostate Adenocarcinoma Metastasis to the Bilateral Ureters: An Unusual Pattern Suvra Roy, MD, L. Maximilian Buja, MD, University of Texas Health Science Center at Houston We report an autopsy of a patient with prostate cancer who had hydronephrosis and sepsis due to obstruction from Downloaded from https://academic.oup.com/ajcp/article/144/suppl_2/A004/1772163 by guest on 23 September 2021 bilateral ureteral metastasis of prostate adenocarcinoma. He was an 82-year-old man who presented to the emergency department with weakness and shortness of breath. Fifteen years earlier, he had been diagnosed with prostate cancer , underwent chemotherapy, and was in remission for 10 years. Eighteen months ago, he developed a recurrence and began chemotherapy again but, because of his worsening renal condition, stopped the chemotherapy about 4 months ago. On admission, he was found to have chronic kidney disease, stage 5, and sepsis. Abdominal CT was negative for genitourinary mass. His condition deteriorated rapidly and he developed bradycardia and then pulseless electrical activity (PEA). He went into cardiac arrest for 30 minutes without return of pulse and remained in PEA. His poor prognosis was explained to his family and, per the family’s wishes, resuscitation was stopped, and the patient died. Autopsy revealed bilateral dilated renal pelvis, trabeculated urinary bladder and enlarged prostate. No gross evidence of metastasis was identified in lymph nodes or bone. However, the openings of the ureters revealed papillary masses involving the distal ureters bilaterally, but not involving the bladder. Microscopic examination of the masses revealed atypical tumor cells with highly pleomorphic features. -
Germ Cell Origin of Testicular Carcinoid Tumors Phillip H
Imaging, Diagnosis, Prognosis Germ Cell Origin of Testicular Carcinoid Tumors Phillip H. Abbosh,1Shaobo Zhang,1Gregory T.MacLennan,3 Rodolfo Montironi,4 Antonio Lopez-Beltran,5 Joseph P. Rank,6 LeeAnn Baldridge,1and Liang Cheng1, 2 Abstract Purpose: Carcinoids are neuroendocrine tumors and most frequently occur within tissues derived from the embryonic gut.These tumors can occur in any organ site but are rare in the testis. The cell type giving rise to testicular carcinoid is unknown.We hypothesized that testicular carci- noid may have a germ cell origin. Experimental Design: We describe our analysis of protein and genetic markers of germ cell neoplasia, using immunohistochemistry and fluorescence in situ hybridization, in four testicular carcinoid tumors. Results: All four cases of testicular carcinoid tumor arose in a background of mature teratoma. Isochromosome 12p was identified in carcinoid tumor cells in all four samples. 12p overrepresen- tation was also observed in three cases. Isochromosome 12p and 12p overrepresentation were present in cells of coexisting mature teratoma in three cases. Carcinoid tumors showed strong immunoreactivity for synaptophysin and chromogranin, but no immunoreactivity for OCT4, CD30, c-kit,TTF-1, and CDX2. Membranous and cytoplasmic staining for h-catenin was detected in three cases. Conclusion: Our findings suggest that testicular carcinoid represents a phenotypic expression of testicular teratoma and is of germ cell origin. Testicular carcinoid tumor is rare. It was originally reported in Materials and Methods 1954 by Simon (1) who described it as part of a cystic teratoma, and additional cases have been subsequently reported. All Patients. We analyzed four cases of testicular carcinoid tumor. -
