Lipid histiocytosis of the gallbladder neck lymph node is rarely reported nowadays. Two obese patients presented with gallbladder lithiasis detected on CT scan. The treatment consisted in coelioscopic cholecystectomy. Microscopy revealed subacute/chronic lithiasic cholecystitis and foci of vacuolated cells in the gallbladder neck lymph node. These cells were positive for CD68, CD31, S100 protein, and adipophilin and negative for cytokeratin and Alcian blue. In conclusion, we report lymph node lipid histiocytosis diagnosed microscopically after cholecystectomy. While such lesions may remain unidentified on imaging procedures, the microscopic analysis may require special stains and immunohistochemistry for ruling out adenocarcinoma metastasis.

Immunotherapy (IO) has increasingly been demonstrated to provide therapeutic benefit to patients with metastatic colorectal cancer (mCRC). However, only a subset of mCRC tumors respond to IO. Monitoring response with tumor biomarkers like carcinoembryonic antigen (CEA) has been challenging in patients with microsatellite stable (MSS) mCRC due to low expression of CEA (CEA/lo). Noninvasive blood-based biomarkers such as circulating tumor DNA (ctDNA) can inform early treatment response and augment radiographic monitoring. We describe a case study of a patient with chemotherapy-refractory CEA/lo MSS mCRC, with metastatic disease present in a cardiophrenic lymph node. The patient was given 2 cycles of combination IO (ipilimumab/nivolumab). Response was monitored by ctDNA using a multiplex PCR next-generation sequencing assay, CEA, and CT scan. After IO administration, ctDNA levels rapidly declined, becoming undetectable. This was concurrent with radiographic resolution of the lymph node metastasis. Serial monitoring of CEA during this same period was uninformative, with no significant changes observed. Significant decline in ctDNA identified metastatic response to IO in a patient with CEA/lo, MSS mCRC and was concurrently validated by CT scan. This case study provides evidence that ctDNA can be used as a prospective surrogate for radiographic tumor response.
