Sarcomatoid Squamous Cell Carcinoma of the Penis - a Report of Two Cases.

Background: Sarcomatoid (spindle cell) squamous cell carcinoma is a rare, highgrade, aggressive tumor consisting of the squamous cell carcinoma admixed with the malignant spindle cell (sarcomatoid) elements. These tumors are relatively uncommon in the genitourinary system and particularly in the penis.

Materials And Methods: Two sarcomatoid squamous cell carcinomas of the penis were diagnosed in our hospital between 2012 and 2015.

Diagnostic Value of ERG in Prostate Needle Biopsies Containing Minute Cancer Foci.

Background: Prostate carcinoma (PC) is the second most diagnosed cancer in men population worldwide. The small amount of the tissue in prostate needle biopsy is often sufficient for the correct interpretation. Novel antibodies, as ERG, could add to the diagnostic value of IHC study in analysing difficult core biopsies.

Lack of ERG-antibody in Benign Mimickers of Prostate Cancer.

Introduction: Prostate carcinoma (PC) is the second most diagnosed cancer in men worldwide. Prostate tissue in needle biopsy expresses a wide variety of architectural patterns some of which are difficult to interpret. Immunohistochemical markers, such as AMACR, p63 and 34βE12 that are currently used in diagnosing prostate cancer, are of great value, but often their interpretation is ambiguous.

Bilateral pheochromocytoma/intra-adrenal paraganglioma in von Hippel-Lindau patient causing acute myocardial infarction.

A 26-year-old male presented to the emergency department complaining of obstipation, severe headache and abdominal pain. An autopsy revealed bilateral pheochromocytoma and acute myocardial infarction. The tumor cells showed positive immunoreactivity of both chromogranin A and synaptophysin and were negative for adrenocortical markers such as SF-1, c17, scc, 3-HSD as well as SDHB, suggesting a germline mutation of the gene SDHB or SDHD.
