Chronic Acalculous Cholecystitis

Comments:
Chronic Acalculous Cholecystitis: The mucosa is congested and shows cholesterolosis (best seen along the upper edge on the left). The darker patches are bile-stained mucosa. Once the bile leaks into the lamina propria, it elicits a histiocytic response consisting of sheets of histiocytes with dusky-brown pigment granules (Ceroid pigment) within pale cytoplasm.
