Resection of previously inoperable retroperitoneal liposarcoma.

We present a case of successful resection of a large right upper quadrant retroperitoneal dedifferentiated liposarcoma involving multiple adjacent organs, initially considered inoperable in a patient in his 40s. This case highlights the importance of extensive preoperative planning and a multidisciplinary approach in achieving a greater chance of curative resection. Preoperative optimisation included neoadjuvant chemotherapy, concurrent portal vein embolisation and hepatic vein embolisation.

Subset-specific Retention of Donor Myeloid Cells After Major Histocompatibility Complex-matched and Mismatched Liver Transplantation.

Background: During solid organ transplantation, donor leukocytes, including myeloid cells, are transferred within the organ to the recipient. Both tolerogenic and alloreactive roles have been attributed to donor myeloid cells; however, their subset-specific retention posttransplantation has not been investigated in detail.

Methods: Major histocompatibility complex (MHC)-matched and mismatched liver transplants were performed in mice, and the fate of donor and recipient myeloid cells was assessed.

Liver Transplant for Adult Recurrent Hepatic Mesenchymal Hamartoma and a Feasible Treatment Modality: A Case Report and Literature Review.

Background: Adult hepatic mesenchymal hamartoma (HMH) is an extremely rare hepatic tumor. Recurrence following complete resection is uncommon. Liver transplantation (LT) is described as a possible treatment option in nonresectable HMH.

Dynamic changes to tissue-resident immunity after MHC-matched and MHC-mismatched solid organ transplantation.

The heterogeneous pool of tissue-resident lymphocytes in solid organs mediates infection responses and supports tissue integrity and repair. Their vital functions in normal physiology suggest an important role in solid organ transplantation; however, their detailed examination in this context has not been performed. Here, we report the fate of multiple lymphocyte subsets, including T, B, and innate lymphoid cells, after murine liver and heart transplantation.
