Burkitt's lymphoma in the adult as an unusual cause of large bowel obstruction.

Bowel obstruction is an uncommon clinical presentation in Burkitt´s lymphoma, specially in adults. This type of lymphoma is classified within B-cell non-Hodgkin´s lymphomas, which is characterized by its aggressiveness and quickly tumoral growth. The clinical presentation related to the gastrointestinal tract is unusual, but it can be presented as intussusception, obstruction or ischemic perforation. Here we describe a case of Burkitt´s lymphoma with bowel obstruction as a clinical debut.

Primary cavernous hemangioma of the thyroid mimicking an ectopic cervical thymoma.

Hemangiomas are one of the most common soft tissue tumors, most of which are located in the skin and subcutaneous tissue. However, a primary thyroid hemangioma is extremely infrequent, so there are only a few cases described in the current literature. As the clinical presentation and characteristics in the imaging tests are non-specific, it is difficult to obtain a preoperative diagnosis. In most cases, the definitive diagnosis is achieved by the histological examination. Due to the rarity of this tumor, we described the case of a 51-year-old female patient affected by thyroid cavernous hemangioma, the differential diagnosis that we considered and a review of the current literature.

Pancreatic lipoma: diagnostic boom of a rare mesenchymal tumor.

Following the incidental finding of a tumor in a 58-year-old female, diagnosed as pancreatic lipoma, histologically confirmed by fine-needle aspiration biopsy (FNAB) with endoscopic ultrasound (EUS), we made a review in our center between 2018 and 2020, with 14 cases diagnosed of pancreatic lipoma by computarized tomography (CT) or magnetic resonance imaging (MRI).
