Hepatic granulomas are noncaseating in which condition?

The key idea is that sarcoidosis forms noncaseating granulomas in the liver. In this condition, granulomas are tightly organized aggregates of epithelioid macrophages and multinucleated giant cells with no central necrosis, reflecting a noninfectious granulomatous process. This noncaseating pattern helps distinguish sarcoidosis from infections like tuberculosis, where the granulomas are classically caseating with a central necrotic area. Fungal infections such as Histoplasma or Coccidioides can also cause hepatic granulomas, but they are typically associated with necrosis or identifiable organisms, especially in disseminated disease. So, seeing noncaseating hepatic granulomas points toward sarcoidosis.
