Surgical Management of a Giant Inflammatory Hepatocellular Adenoma in a Young Female.

Hepatocellular adenomas are rare and benign primary neoplasms of phenotypically mature hepatocytes. Our understanding of this pathology has greatly improved due to advances in molecular and anatomic knowledge. This article provides an in-depth review of hepatic adenomas (HCA) while presenting the case of a 20-year-old patient with a giant inflammatory hepatocellular adenoma with an atypical presentation, in whom surgical intervention was performed via right hepatectomy. In the post-surgical course, the patient had an in-hospital stay of three days with no complications. During outpatient monitoring via laboratory tests and imaging at eight months, the patient did not present any trace of recurrence.

A Giant Malignant Solitary Fibrous Tumor of the Pancreas: A Case Report and Review of the Literature.

We present a case report of a giant solitary fibrous tumor (SFT) with a review of the literature and discuss its biological features and diagnosis. A 43-year-old man presented to our emergency department with abdominal pain and distension with an evolution of two days. Contrast-enhanced computed tomography (CT) showed a large, well-circumscribed semisolid mass (12 cm x 10 cm x 12 cm) localized in the pancreatic head. The histological diagnosis obtained by endoscopic ultrasound-guided trans-duodenal tumor biopsy with fine-needle aspiration showed proliferating short spindle-shaped cells, suggesting a mesenchymal neoplasia of low grade. We proceeded to a Whipple surgical technique. The histopathological study of the resected tumor confirmed proliferating spindle-shaped cells in the tissue, and one mitotic figure was observed in 10 high-power fields (HPFs). Immunostaining was positive for CD34 and STAT-6. The histological diagnosis was a malignant pancreatic SFT. In the six months posterior to the surgical procedure, the patient has been free of recurrent disease. Preoperative diagnosis is difficult and requires comprehensive evidence including clinical, immunohistochemistry, and histological features. Since there are currently no recognized best practices, we advise total surgical excision and careful clinical monitoring.

A 24-Year-Old Male Patient With an Ostium Secundum Complex Atrial Defect Secondary to a Perforated Aneurysm With Inferior Vena Cava Agenesis.

The article describes a successful clinical outcome in the case of a 24-year-old male with a diagnosis of an ostium secundum atrial defect secondary to a perforated aneurysm associated with vena cava agenesis. During hospitalization, an echocardiogram revealed the presence of ostium secundum inter-atrial communication with a left to right shunt, a left ventricular ejection fraction (LVEF) of 60%, and mild pulmonary hypertension, measured at 40 mmHg. CT imaging showed anomalous dilation of the azygos vein (16.8 mm), associated with interruption of the vena cava in the intrahepatic and adrenal portion, continuing through the azygos system and draining into the superior vena cava. Open-heart surgery was performed with pericardium patch placement on the defect. Postoperative transthoracic echocardiography revealed a tracking of the interatrial septum, with adequate placement of the surgical patch and no evidence of residual short circuits. The postoperative recovery was favorable, and the patient was discharged five days after surgery. Outpatient monitoring at the first and third months showed no complications during physical examination and echocardiogram imaging.

Placental Transmogrification of the Lung in a Patient Without Emphysematous Disease.

We present a 47-year-old male without a relevant history or past respiratory diseases. He debuted with an acute, non-complicated COVID-19 infection, and later he started with mMRC-2 dyspnea, accompanied by a non-expectorant cough of four months evolution. A CT thoracic scan showed a dilatation of the aerial homogenous space and a well-defined anterior left pericardiac level, and a pericardial left bulla was diagnosed. The patient was treated with surgical intervention by video-assisted thoracoscopic surgery and had an adequate post-surgical evolution. The PPT must be managed by a multidisciplinary team with the definitive treatment of surgical resection.

Isolated Fallopian Tube Torsion with Necrotic Hemorrhagic Cyst in an 11-Year-Old Girl Diagnosed by Laparoscopy.

Isolated fallopian tube torsion (IFTT) is a rare pathology that causes acute abdomen in women, it is even less common in pediatric patients. We present a case of an 11-year-old girl who presented with abdominal pain 24 hours of evolution, the diagnosis could not be specified with cabinet methods, so the definitive diagnosis was made using a diagnostic laparoscopy. A necrotic hemorrhagic tubal cyst was found. A left salpingectomy had to be performed due to necrosis. Early diagnosis can have a positive impact on the fertility of these patients.
