IgG4-related prostatitis is a rare and likely under-recognised manifestation of IgG4-RD. Its overlap with benign and malignant prostatic disorders delays diagnosis. Serum IgG4 and PSA are unreliable markers of disease and monitoring. Glucocorticoids remain first-line therapy, with surgery in obstructive cases. Multicentre studies are needed to define prevalence, natural history, and optimal management.
