p63-positive prostate carcinoma-A very rare presentation.

Prostate cancer being the world's leading cause of cancer and also the second most common cancer in men is posing challenges in its diagnosis. Immunohistochemistry with markers like high molecular weight cytokeratin, p63 aid in the diagnosis. The absence of p63 and high molecular weight cytokeratin and presence of p504s in the biopsies indicate malignant lesions.
