[Treatment of a patient with giant solitary fibrous tumor of the left hip]. / Lechenie patsientki s gigantskoi gemangioperitsitomoi.

The authors report surgical treatment of a 59-year-old female with a giant solitary-fibrous tumor of the left hip. Previous excision of hip hemangioma was performed in 2016. Recurrent tumor with fast growth has occurred since 2018. The neoplasm consisted of 2 tumors connected by vascular structures. CT revealed soft tissue neoplasms in the upper third of the left thigh (anterior, medial and dorsal regions). Large tumors with an isthmus along the inner surface had tuberous contours and internal septa. The last ones and walls accumulated contrast agent. No structural damage to femoral muscles was observed. The patient underwent resection of tumor and vascular ligation (great saphenous vein and its tributaries along the anterior surface, arteries from the deep femoral artery system along the posterior surface of tumor). There were no early postoperative complications. There are no complaints within 6 month after surgery. There is no lower limb dysfunction.

[Treatment of patient with echinococcosis of lungs and mediastinum]. / Lechenie patsienta s ékhinokokkozom legkikh i sredosteniia.

It is presented diagnosis and treatment of 53-year-old man with multiple echinococcosis of the lungs and mediastinum. The diagnosis was confirmed by chest CT. Patient previously underwent surgery for liver echinococcosis. Excision of echinococcosis lesions in the lungs and mediastinum was performed. Chest wall repair was made by using of pedicled flap from the right lateral surface of the thorax followed by donor site plasty by polypropylene mesh. There were no intraoperative complications. In the postoperative period, intermediate bronchus occlusion mas made by occluder due to persistent air output through the pleural drains. The device was removed after 4 days. The patient was discharged. Multidisciplinary approach is useful to achieve good results in these patients.

Ultrastructural study of cell populations in the gastric transplant after esophagoplasty.

Ultrastructural characteristics of cell populations in the gastric tube mucosa were studied after plastic surgery for benign esophageal disease. The foveolar epithelium mainly consisted of secretory active mucocytes with small changes in cytoplasmic organelles. Functionally immature parietal cells and gland cells in the epithelium of fundal glands were characterized by atrophy and degeneration. Ultrastructural features of the epithelial compartment attest to adaptive cellular hypersecretion of the mucoid against the background of impaired acid production and enzyme secretion. The stromal compartment was characterized by low pinocytotic activity of endothelial cells in blood vessels and polymorphism of smooth muscle cells. Hypertrophic leiomyocytes were shown to dominate in the population of these cells. Some cells had signs of biosynthesis and reduction of filaments. Single leiomyocytes were degenerated. The observed ultrastructural modification of epithelial and connective cells can be interpreted as structural adaptation of the gastric transplant.

Effect of esophagoplasty on the mucosa structure in the gastric transplant.

Structural modifications of the gastric tube transplant were studied during the delayed period after esophagoplasty carried out for benign diseases of the esophagus. Adaptive and pathological reactions manifesting in atrophic and sclerotic changes in the mucosa formed the basis for transplant reorganization. The leading morphological markers were degeneration and hypersecretion of the foveolar epithelium, focal atrophy of the fundal glands with foci of pyloric metaplasia, hypertrophy and fibrosis of the muscle plate, and stromal sclerosis. Abundant polymorphonuclear infiltration of the mucosa with lymphoid follicular hyperplasia were observed in H. pylori contamination of the gastric transplant.
