case_images: Histological analysis revealed a metastatic adenocarcinoma with diffuse infiltrative growth pattern consisting of small interspersed nests of epithelial tumor cells (Fig. 4A). Immunohistochemical expression of prostate-specific acid phosphatase (PSAP) confirmed the lesion's nature as a metastasis of the patient's primary prostate adenocarcinoma (Fig. 4B).
