Background: Cryptorchidism is characterized by the incomplete descent of one or both testicles to the scrotum, being a hereditary alteration and frequently an unilateral condition. Besides the sexual and aggressive behaviour, the retained testicle is commonly located in abdominal cavity, being considered a risk factor for neoplasm development. The most common testicular neoplasm reported in mammalian species are Sertoli cell tumors, Leydig cell tumors, seminomas and teratomas. A presumptive diagnosis of testicular tumor can be achieved by ultrasonography, although the definitive diagnosis is obtained only by histopathology. In this report, we are presenting a of testicular teratoma in an unilateral abdominal cryptorchid horse. Case: A stallion, American Quarter Horse, 3 year-old, was attended and presented right testicle retained and a left testicle in the scrotum. Transrectal palpation was used to identify a round and firm structure, presumably the right testicle, lateral to the urinary bladder and located in the right side of the abdomen.  Further, a transrectal ultrasound examination showed a complex, round mass with irregular edges containing both cystic and solid structures, hypoechoic fluid-filled cavities separated by linear hyperechoic septa. After a clinical examination, the animal was diagnosed with cryptorchidism and was submitted to orchiectomy and cryptorchidectomy by inguinal approach. Surgery was performed under general anesthesia and postoperative care included cold shower, anti-inflammatory and antibiotic therapy. Testicles were surgically removed and further sent for histopathological examination. The visual appearance of the right undescended testicle showed multiple round, cystic, and solid structures on outer surface, while the left descended testicle was apparently normal. The macroscopic evaluation showed that the affected testicle consisted of a firm to soft solid mass with multiple fluid-filled cystic areas. Microscopically, the testicular architecture was replaced by cysts, fibrous tissue, adipose tissue, glandular structures, and foci of calcification. The histology revealed that the retained testicle had a testicular teratoma. Discussion: Reproductive disorders are common in horses and represent a significant part of the equine practitioner routine. Equine cryptorchidism is the most common non-lethal developmental defect of stallions; Surgery is the best treatment, since this alteration is hereditary. Teratomas have been reported more often in cryptorchid testicles, being usually just diagnosed as an incidental finding during surgical procedure. Under field conditions, usually the testicles are not sent for histopathological evaluation and this fact can contribute to underdiagnoses. Ultrasonography allows clinicians to determine testis location as well as morphological changes in the testes, as well as to elaborate a presumptive diagnose of testicular neoplasm. Histopathology is the best exam to achieve definitive diagnoses in the presence of testicular alterations. In our report, diagnosis of testicular neoplasia was not made before surgery and testicular mass was an incidental finding during the pre-surgical examination. Before testicular enlargement or presence of testicular mass, neoplasia should be included in the differential diagnosis. In conclusion, although rare, teratoma should be included in differential diagnoses of retained testicles, especially those with morphological alterations.

Abstract Background Mesenchymal hamartoma is the second most common benign liver tumor in children, with 20% of the cases diagnosed during the neonatal period. The exact etiology in still unclear, and most investigators believe that it is a developmental anomaly rather than a true neoplasm. The presentation of these tumors is highly variable depending on the lesion’s size, ranging from small asymptomatic lesions to very large tumors with life threatening complications. Radical surgical excision, whenever possible, is the gold standard for treating these lesions to avoid the problems of local recurrence and possible malignant transformation. We present the rare occurrence of an entirely solid, giant hepatic mesenchymal hamartoma in a 3-week-old male newborn and discuss the mode of presentation, as well as the diagnostic and therapeutic approach. Case presentation A 3-week-old male newborn was referred to our institution with huge abdominal distension and respiratory distress. Imaging studies confirmed the presence of a very large solid intraabdominal mass occupying the majority of the abdominal cavity and abutting the inferior aspect of the right lobe of the liver, but did not reveal the diagnosis. At laparotomy, a huge solid mass was found attached to the right lobe of the liver. Complete excision was done, and histopathological examination confirmed the diagnosis of mesenchymal hamartoma. Conclusion Although rare, mesenchymal hamartoma of the liver can present as a neonatal surgical emergency. Emergency intervention is required in symptomatic patients. Radical surgical intervention is possible and is the treatment of choice to relieve the patient’s symptoms and avoid future complications.

Paraganglioma is one of the tumors that is rarely found in the practice of an otorhinolaryngologist. Approximately 90% of tumors from nonchromaffin paraganglia occur in the adrenal glands. Nevertheless, 5 – 10 % of paragangliomas have different localization: 85 % - in the abdominal cavity, 12 % - in the chest, 3 % - on the head and neck. Paraganglioma grows slowly, but there is a risk of its degeneration into a malignant neoplasm. Diagnosis of paraganglioma includes CT, MRI; Ultrasound scintigraphy, arteriography, biopsy, histological examination. The main treatment for this education is surgical. As this tumor occurs rather rarely, we present a clinical observation of a paraganglioma of the nasal cavity. Purposes. The purpose of this article is to describe a rare clinical case of paraganglioma of the nasal cavity to determine diagnostic measures and treatment tactics to help a practical doctor. Materials and methods. On 01/18/2019 patient M., 52 years old, with complaints of recurrent nosebleeds, difficulty breathing in the right half of the nose was received at the ENT Center «V. T. Lisovets Dynasty». Bleeding from the nasal cavity has been disturbing the patient twice a week for 6 months, for no apparent reason. An increase in the frequency of bleeding up to 4–5 times a week has been noticed for the last month. On a series of MRI tomograms dated 12.24.2019, in the front sections of the nasal concha, on the right, a volumetric pathological formation with dimensions of about 10 × 12 mm, with tuberous contours, an inhomogeneous MR structure was determined. Bone structures were not affected. The neoplasm narrowed the lumen of the nasal cavity on the right. Conclusion: MR-picture of the pathological volumetric formation (of blastomatous nature) of the nasal cavity on the right. Results. On 01/21/2019 the patient underwent surgical removal of the neoplasm within healthy tissues using a radioknife. An anterior nasal tamponade with a hemostatic preparation was performed. The postoperative period was without complications. A morphological examination of surgical material N 330/2019 yielded the following results: a microscopic examination determined a tumor with the same histological picture in the form of alveolar and solid areas, a branched network of blood vessels of capillary type, fibrous tissue of various thicknesses. Tumor parenchyma was represented by epithelioid morphology cells with pronounced eosinophilic cytoplasm, a large nucleus with granular chromatin. Cells with a weakly expressed eosinophilic cytoplasm, with small monomorphic nuclei were also found. Conclusions. The patient was diagnosed with a rare tumor of neuroectodermal nature, which in most cases has a benign nature, slow growth and develops from nonchromaffin ganglia, which are scattered throughout the body. As the formation grows, the arterial and venous network of vessels develops. The clinical picture of a neoplasm of the nasal cavity is often masked by the symptoms of chronic polypousrhinosinusitis, vasomotor and chronic hypertrophic rhinitis. Based on the foregoing, this clinical cases valuable for the practitioner in terms of the features of localization, diagnosis and these lection of the correct therapy for this category of patients.

Minilaparotomy Approach

Abstract The aim of the study was to assess the prepubic minilaparotomy approach in the surgical treatment of prostatic disorders in dogs. The technique of a limited approach to the prostate was developed on the fresh cadavers of 14 intact adult male dogs, diversified in regard to size and body weight. The abdominal cavity was opened in midline, from the right-sided prepubic parapenile incision. The cut was limited to 7 cm. Afterwards, it was expanded by self-retaining retractors: Gelpi, Weislander, Finnochetto Baby, and Adson. Finnochetto Baby and Gelpi retractors used in pairs enabled an adequate exposition of the prostate in small dogs. The Finnochetto Baby retractor enabled an adequate exposition of the prostate in medium dogs and the Adson retractor - in large and giant dogs. The Weislander and Gelpi retractors used individually did not allow for sufficient access to the prostate in any group of the cadavers. Prepubic minilaparotomy can be a useful surgical approach in the treatment of prostate disorders in dogs. It can be used especially for minor surgical procedures, e.g. sampling of large tissue specimens for histopathological examination, partial prostatectomy, or treatment of intraparenchymal cavitary lesions.

Intra-testicular epidermoid cyst of testis is a benign tumour and accounts for 1-2% of all testicular neoplasms. It is a benign lesion, and should be distinguished from dermoid cyst or teratoma, which have a considerable malignant potential. We describe a rare case of testicular epidermoid cyst in an elderly male presenting with gradually increasing testicular mass since 8 months. Local examination revealed a non-tender, irregular, hard mass in the right testis. All routine laboratory investigations along with tumour markers were within normal limits. Ultrasound showed features of a testicular neoplasm following which orchidectomy was performed. Grossly, cut surface of testis showed a cyst measuring 4x2x1cm and microscopic examination revealed features of an epidermoid cyst. Extesive sampling excluded the possibility of a teratomatous focus. This case is described owing to the rarity of this neoplasm and the unusual clinico-radiological presentation. The pre-operative diagnosis of this tumour can be made if characteristic sonographic and MRI findings are obtained in the absence of which these masquerade neoplastic lesions. Histopathological examination thus is vital for a decisive diagnosis.

Introduction: Nowadays, co-infection by interspecific organisms is major threat in infection control. To identify the effective combination of drugs to control the keratitis caused by Candida albicans with Pseudomonas aeruginosa are attributed in this study. Materilas and Methods: The patient of a 47 years old male farmer with infection in the right eye which showed redness and watering was treated with fortified cefazolin and fortified tobramycin before referral. No pigmentation or vascularisation was noted. The excised corneal button was also subjected to microbiological and histopathological examination. Results: A rare case of keratitis caused by co-infection of Candida albicans with Pseudomonas aeruginosa was identified. Results confirmed the inter-specific interaction of the two microorganisms. Conclusion: Cases of co-infection by Candida and Pseudomonas are not abundantly reported and difficult to treat. In this case, treatment involved Amphotercin-B and ciprofloxacin, effectively eradicated the infection. This therapy may be successfully implied for such cases of co-infection in future.

Background:Radiotherapy is one of the treatment methods for cancers using ionizing radiations. About 70% of cancer patients undergo radiotherapy. Radiation effect on the skin is one of the main complications of radiotherapy and dose limiting factor. To ameliorate this complication, we used melatonin as a radioprotective agent due to its antioxidant and anti-inflammatory effects, free radical scavenging, improving overall survival after irradiation as well as minimizing the degree of DNA damage and frequency of chromosomal abrasions.Methods:Sixty male Wistar rats were randomly assigned to 4 groups: control (C), melatonin (M), radiation (R) and melatonin + radiation (MR). A single dose of 30 Gy gamma radiation was exposed to the right hind legs of the rats while 40 mg/ml of melatonin was administered 30 minutes before irradiation and 2 mg/ml once daily in the afternoon for one month till the date of rat’s sacrifice. Five rats from each group were sacrificed 4, 12 and 20 weeks after irradiation. Afterwards, their exposed skin tissues were examined histologically and biochemically.Results:In biochemical analysis, we found that malondialdehyde (MDA) levels significantly increased in R group and decreased significantly in M and MR groups after 4, 12, and 20 weeks, whereas catalase (CAT) and superoxide dismutase (SOD) activities decreased in the R group and increased in M and MR groups during the same time periods compared with the C group (p<0.05). Histopathological examination found there were statistically significant differences between R group compared with the C and M groups for the three different time periods (p<0.005, p<0.004 and p<0.004) respectively, while R group differed significantly with MR group (p<0.013). No significant differences were observed between C and M compared with MR group (p>0.05) at 4 and 20 weeks except for inflammation and hair follicle atrophy, while there were significant effects at 12 weeks (p<0.05).Conclusion:Melatonin can be successfully used for the prevention and treatment of radiation-induced skin injury. We recommend the use of melatonin in optimal and safe doses. These doses should be administered over a long period of time for effective radioprotection and amelioration of skin damages as well as improving the therapeutic ratio of radiotherapy.

Abstract Background An adenomyoma is a well circumscribed form of adenomyosis and can be located within the myometrium, in the endometrium as a polyp, or extrauterine with the last being the rarest presentation amongst the three. With the ongoing advancement in gynecological surgery, the use of electromechanical morcellators have made the removal of large and dense specimens possible with minimally invasive techniques. However, it has also caused an increase in complications which were previously rare. Whilst the tissue is being grinded within the abdominal cavity, residual tissue can spread and remain inside, allowing for implantation to occur and thereby giving rise to recurrence of uterine tissue as a new late postoperative complication. Case presentation A 45-year-old woman presented with worsening constipation and right iliac fossa pain. Her past surgical history consists of laparoscopic supra-cervical hysterectomy that was indicated due to uterine fibroids. Computerized tomography and magnetic resonance imaging were done, which showed an irregular lobulated heterogeneous mass seen in the presacral space to the right, located on the right lateral aspect of the recto-sigmoid, measuring 4.5 × 4.3 × 4.3 cm in size. A transvaginal ultrasound revealed a cyst in the left ovary. The patient had a treatment course over several months that included Dienogest (progestin) and Goserelin (GnRH analogue) with add-back therapy. In line with the declining response to medications, the patient was advised for a laparoscopic ovarian cystectomy. During the surgery, an additional lesion was found as a suspected fibroid and the left ovarian cyst was identified as pockets of peritoneal fluid which was sent for cytology. The surgical pathology report confirmed adenomyosis in both specimens, namely the right mass and the initially suspected fibroid. Conclusion In this case report, we showcase a rare occurrence of an extrauterine adenomyoma presenting two years post laparoscopic morcellation at hysterectomy. This poses questions regarding the benefits versus risks of power morcellation in laparoscopic hysterectomy.
