RESUMO
Adrenal myelolipoma is a rare benign neoplasm composed of mature adipose tissue and myeloid tissue with a variable amount of hematopoietic elements. Most patients are asymptomatic although some present with pain or even endocrine dysfunction. The rising use of CT and MRI scans has led to an increase of the detection of adrenal myelolipomas in recent years. The indications for surgery are symptomatic patients and lesions bigger than 5 cm or suspicious for malignancy. A case of a 50-year-old woman is presented here who was referred for surgical resection of a large nonfunctioning right adrenal mass. The neoplasm was resected through a midline laparotomy. Histopathology revealed a lesion consisting predominantly of fatty issue containing all types of hematopoietic stem cells and confirmed the diagnosis of myelolipoma.
RESUMO
Metastases from renal cell carcinoma (RCC) are rarely located in the small bowel and usually present either with iron deficiency anaemia due to occult bleeding or obstructive symptoms. A 65-year-old man with not known malignancy was admitted to our hospital with symptoms of intermittent bowel obstruction. The abdominal computed tomography (CT) scan depicted a large tumour of the right kidney and obstruction of the small intestine at the level of the proximal jejunum. A jejuno-jejunal intussusception was found on laparotomy, due to endoluminal lesions that proved to be metastatic from RCC. Intussusception of the small bowel due to metastatic RCC is a very rare combination and only a few such cases have been reported so far in the literature.
