Primary pleuropulmonary synovial sarcoma is extremely rare. The diagnosis can only be made after having eliminated an extrapleuropulmonary localization in the past and at the time of diagnosis. Our presentation is about a 40-year-old woman having a cough and dyspnea since three weeks ago; imaging had showed a left pleurisy with pleuropulmonary process. Histological study of the biopsy confirmed the diagnosis of pleuropulmonary synovial sarcoma. PET-SCAN had not identified any extrathoracic localization. This tumor is known for its aggressive nature and high risk of metastasis. Its primitive character is retained following a diagnostic procedure of exclusion. Surgical treatment remains the best therapeutic tool when it is technically feasible; otherwise the prognosis is often unfortunate. In this paper, we report a case of primary pleuropulmonary synovial sarcoma. Through this case, we present a rare disease that is often difficult to diagnose.

Splenic Metastases

Isolated splenic metastases from colorectal cancer after radical surgical treatment are quite rare. This frequency of metastases is explained by the anatomical, functional and immunological characteristics of the spleen. The literature usually describes single clinical cases followed by accompanied systematic analysis and discussion. Most of the cases are asymptomatic and are accidentally diagnosed, during different types of imaging tests, including increased levels of tumor markers. The progression free survival was 3 144 months after surgical treatment of the primary tumor in most of the patients. By the nature of the lesion, metastases can be synchronous and metachronous, as well as solitary and multiple. Aim. To discuss two clinical observations of isolated splenic metastases in patients after left colic flexure cancer surgical treatment. Materials and methods. We observed 2 female patients, 68 and 70 years old, with isolated splenic metastatic after left colic flexure cancer radical surgical treatment. Results. Both cases are considered to be metachronous and the interval of absence of disease manifestations are 21 and 10 months, respectively. The patients with stage IIB and IIC left colic flexure cancer underwent left hemicolectomy followed by adjuvant polychemotherapy using regimen with 6 cycles of FOLFOX. The histological study revealed a moderately differentiated adenocarcinoma with invasion into all layers of the wall and into the surrounding tissue. There were no lymph node metastases. In the course of dynamic observation, during the next examination with the help of ultrasound examination we revealed splenic metastasis, and confirmed this using positron emission tomography/computed tomography. The disease was without clinical picture. The time interval after the surgery before diagnosis was 21 and 10 months, respectively. Surgery was performed in the volume of splenectomy. Isolated splenic metastases in the absence of other manifestations of the disease were found intraoperatively. The histological study showed the splenic metastasis of the same type of cancer as the primary tumor. The polychemotherapy using regimen with 6 cycles of XELOX was performed during the postoperative period. Patients are alive without signs of the disease over the period of 5 and 26 months, respectively. Conclusion. Isolated splenic metastases are extremely rare, more often when the primary tumor is located in the left side of the colon. The showed cases illustrate the need and importance of the monitoring the patients after surgical treatment for colon cancer. The use of positron emission tomography/computed tomography helps to understand the real prevalence of the tumor process, without using invasive methods. The surgery in the volume of splenectomy followed by chemotherapy are the main therapeutic options. In one clinical case, the metastases were multiple, and in the other one was solitary metastasis. Patients are alive without signs of the disease over the period of 5 and 26 months, respectively.

Primary cardiac tumors are quite rare pathology in newborns. The most common of it is rhabdomyoma. Myxomas, in contrast to the adult population, are much less common. Aim. In our report we present our experience in treating newborns with cardiac tumors. Material and Methods. We report two clinical cases. The children were taken to hospital in urgent order with critical hemodynamic disorders caused by tumor process. The tumors were removed during urgent surgeries. According to histological study these were myxomas. Results and discussion. During further observation no signs of tumors recurrences were detected. For successful treatment of cardiac tumors is very important timely diagnosis, that can be difficult due to the lack of specific symptoms in children. Conclusions. Echocardiography is a key method of diagnosis of such conditions. Surgical treatment is the method of choice in this pathology.

Aim. To substantiate the recommendations on the tactics of recurrent operations for strabismus in children on the basis of histological investigation of the fragments of «weakened» muscles. Methods. Conducted was a retrospective analysis of recurrent surgical treatment of 2 patients with concomitant convergent strabismus. In order to determine the cause of dysfunction of the muscles conducted was a histological study of 80 fragments of the lateral rectus muscles, which were excised during surgical treatment of convergent strabismus. Results. Muscle fibers were found only in the distal sections during the resection of the lateral rectus muscles at a distance of 8.5-9 mm. Taking into consideration the fact that at point were the muscle transitions into the tendon located are the palisade nerve endings, which may play the major role in the contraction process, the exceedence of the above mentioned amount of muscle resection during strabismus surgery is dangerous, since it can lead to the disruption of the eye mobility. Conclusion. During recurrent operations for strabismus correction it is recommended to use major recessions of the «strong» muscles, and for ease of muscle fixation at a great distance from the attachment point - the technique of the «sliding noose».

Aim. The study was conducted to improve the results of the surgical treatment of acute calculous cholecystitis occurring against the background of diabetes mellitus. Materials and methods. In course of our study, we analyzed the treatment results of 687 patients with acute calculous cholecystitis. Depending on the presence of diabetes, all patients were divided into two groups. The main group with concomitant diabetes mellitus included 68 (9,9%) patients, whereas the control group without diabetes included 619 (90,1%) patients. Laparoscopic cholecystectomy was performed on 636 (92,6%) patients, and open cholecystectomy was performed on 51 (7,4%) patients. Results. According to the histological study, the greatest number of destructive forms occurs in patients with concomitant diabetes, operated after 24 hours. The least postoperative complications occur in patients of both groups operated from 12 to 24 hours. However, the incidence of complications is 4-5 times higher in patients with diabetes mellitus. Postoperative complications in patients with acute calculous cholecystitis occurring on the background of sugar diabetes were observed after open cholecystectomy in 33,3% of cases and in 6,5% of cases after laparoscopic surgery.Conclusion In patients with acute cholecystitis and concomitant diabetes, surgical treatment should be performed on the first day after the preoperative preparation during the first 12 hours, aimed at compensating for diabetes and improving microcirculation. The preference should be given to laparoscopic cholecystectomy, which reduces the number of postoperative complications by 5 times and mortality by 4.5 times.

Purpose of the study. Evaluation of the results of surgical treatment of desmoid fibroids (DF) using reconstructive plastic surgery and determination of possible prognostic factors of relapses.Patients and methods. The results of surgical treatment of 40 patients with desmoid fibroids of extra abdominal local­ization were analyzed. In 45% of patients, the tumor was located in soft tissues of the shoulder girdle and upper limb, in 35% — on the trunk, in 20% — in soft tissues of the lower limb and in 7% of patients on the neck. The tumor size varied from 2 to 20 cm, the median was 8 ± 4.38 cm. Surgical treatment for newly diagnosed DF was performed in 22 (55%) patients, and for recurrent tumors — in 18 (45%) patients.Results. According to the planned histological study, negative resection boundaries were established in 24/40 patients (63%). In the remaining 16 cases (37%) positive resection margins were obtained: R1 in 14 patients and R2 in 2 patients. Adjuvant treatment is recommended for 14 patients with resection R1/R2. The duration of follow — up after treatment ranged from 6 to 107 months, median‑16.5 months. During follow-up, relapses were diagnosed in 14 patients (35%). No deaths have been reported.Conclusion. Surgical treatment of DF of extraabdominal localization is accompanied by a sufficiently high frequency of relapses. According to the results of the study, an unfavorable factor in the development of relapses is the location of the tumor in soft tissues of the shoulder girdle and upper limb.

The recent development of the scanning electron microscope has added great impetus to the study of ultrastructural details of normal human ossicles. A thorough description of the ultrastructure of the human ossicles is required in order to determine changes associated with disease processes following medical or surgical treatment.Human stapes crura were obtained at the time of surgery for clinical otosclerosis and from human cadaver material. The specimens to be examined by the scanning electron microscope were fixed immediately in the operating room in a cold phosphate buffered 2% gluteraldehyde solution, washed with Ringers, post fixed in cold 1% osmic acid and dehydrated in graded alcohol. Specimens were transferred from alcohol to a series of increasing concentrations of ethyl alcohol and amyl acetate. The tissue was then critical point dried, secured to aluminum stubs and coated with gold, approximately 150A thick on a rotating stage in a vacuum evaporator. The specimens were then studied with the Kent-Cambridge S4-10 Scanning Electron Microscope at an accelerating voltage of 20KV.
