RESUMO
Primary mesenteric liposarcoma is a rare soft tissue malignant neoplasm. The authors present a case of a 42-year-old male with pain in the abdomen and abdominal mass which showed a desmoid tumor on biopsy and CT shows a mesenteric mass present. The patient underwent exploratory laparotomy and a large tumor was excised. The specimen was sent for histopathology and showed dedifferentiated liposarcoma of the mesentery. Immunohistochemistry showed the tumor cells are diffusely positive for mouse double minute 2 (MDM2), p16, and show patchy positivity for the cluster of differentiation (CD) 34. The cells are negative for smooth muscle actin (SMA), desmin, S100, and ckit. After the surgery, the patient recovered well and was given adjuvant chemotherapy with doxorubicin, ifosfamide, and mesna. The patient has no signs or symptoms of recurrence to date. In this case, the combination of surgery and chemotherapy has shown to have a good clinical outcome.
RESUMO
The liver is the commonest organ affected by hydatid disease. We report a rare case of a 25-year-old female patient who was treated surgically for hepatic echinococcosis two weeks ago with laparoscopic excision of hepatic hydatid cyst with marsupialization and omentoplasty. She then presented with features of obstructive jaundice, which is a known complication following hydatid endocystectomy. Cholangiogram revealed a communication of the residual hydatid cyst with right segmental intrahepatic biliary radicals. She was treated with endoscopic retrograde cholangiopancreatography (ERCP)-guided stenting. ERCP is regarded as an important therapeutic strategy for hydatid cysts occurring in the extra biliary tree either as primary or as complications of liver cysts. It facilitates the clearing of hydatid debris from the biliary tree, and the closure of fistulas and bile leaks followed by laparoscopic cholecystectomy when the hydatid cysts are also located in the gallbladder.
