Soft tissue granulomas

J. PROSTATE, LEFT MEDIAL MIDZONE, BIOPSY:
- BENIGN PROSTATE TISSUE;
- FOREIGN BODY-TYPE GRANULOMA, NONNECROTIZING, SEE COMMENT.

COMMENT:
The granulomas appear to be within the periprostatic soft tissue. They consist of
multinucleated (foreign body-type) giant cells, hyaline material and rare interspersed
neutrophils. No necrosis is identified. This finding may represent a reaction to displaced
epithelium from a previous procedure.

Weight

Inflammation

Micro

The sections show prostate cores with marked inflammation, that partially obscures the gland outlines. The inflammation is predominantly lymphocytic with a lesser amount of neutrophils and plasma cells. Eosinophils are not readily apparent. An isolated granuloma without necrosis is seen in one core.

The gland-to-stroma ratio is within normal limits. Basal cells are identified in the glands. Reactive nuclear changes are present. The gland architecture does not show changes characteristic of neoplasia.
