Answer

Lymphocytic infiltrates are also seen in other organs. Findings from a gastric mucosal biopsy may show lymphocytic infiltrates with atrophic gastritis. A kidney biopsy may show interstitial lymphocytic infiltration. Lung biopsy can reveal infiltrating CD4+ T cells of a lymphocytic interstitial pneumonitis. Salivary gland biopsy can help to detect pseudolymphoma or lymphoma, as well as the noncaseating granulomas of sarcoidosis.
