Histologic examination was performed on uterine biopsy samples of irregular cystic masses noted during caesarean section of a 2-year-old female Boer goat. Histopathologic examination revealed multifocal erosions of the superficial epithelium and multifocal infiltration of the endometrium by widely scattered viable and degenerate neutrophils, lymphocytes, and plasma cells admixed with mild amounts of cellular debris and hemorrhage. The endometrium was markedly expanded by many irregular cystic and hyperplastic glands. This is the first case report of endometritis and cystic endometrial hyperplasia in a goat in North America.

Abstract Background:Primary hepatic sarcomatous carcinoma (PHSC) and primary hepatic sarcoma (PHS) are rare malignancies with frequent overlap in both the clinic and radiology. No comparative study of these tumors for the restricted cases has previously been undertaken. The purpose of our study was to analyze the clinical and imaging features of PHSCs and PHSs, with an emphasis on particularities and similarities through a comparison of the two tumors.Methods: We retrospectively analyzed the clinical and imaging features of 39 patients with pathologically proven PHSCs (n=23) and PHSs (n=16) from four university centers over a 9-year period from 2010-2019. Univariate analyses were performed to determine the consistent and distinctive features. Results:The background of chronic hepatitis or cirrhosis was observed with a high frequency in both of PHSCs (73.7%) and PHSs (62.5%). Tumors with a diameter greater than 10cm were significantly more common in PHSs than PHSCs (p=0.043) and cystic masses were more detected in PHSs (P=0.041). Both PHSCs and PHSs mainly presented hypovascularity (78.3% vs 81.3%). The ring hyper enhancement on the arterial phase (AP) and wash out were more frequently seen in PHSCs and the iso-hypo enhancement on the AP followed persistent or progressive enhancement was more commonly detected in PHSs (all, p<0.05). Conclusion:PHSC and PHS generally present as mass lesions with hypovascularity. The ring hyper enhancement on the AP and wash out favor the diagnosis of PHSC. The large size greater than 10cm, cystic lesion, iso-hypo persistent or progressive enhancement pattern might suggest the possibility of PHSs.

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

Benign intra-abdominal cystic masses in children are rare and they have diverse etiopathogenesis, clinical presentation. The present study highlights the experience in the management of benign intra-abdominal cysts pertaining to the diverse etiologies associated with these lesions. The medical records of our hospital between November 2016 to November 2019 were retrospectively reviewed. Patients with cystic abdominal masses were studied with respect to less different clinical presentations, localization of masses, diagnostic tests, surgical aapproaches, histopathological examinations and outcome. Out of the 55 cases, most common lesion was a choledochal cyst. Miscellaneous diagnosis includes an omental cyst, urachal cyst and a pedunculated bile duct cyst. All the cystic lesions of the abdomen need to be considered as close differentials in clinical practice due to the common presentations and similar symptoms produced by these lesions. All the lesions were managed by exploratory laparotomy except two ovarian cysts which were managed with laparoscopic approach.

PurposeAn early diagnosis of ovarian torsion is sometimes difficult due to variable clinical symptoms and non-specific imaging findings. We retrospectively reviewed patients with pediatric ovarian masses manifesting torsion.MethodsFifty-eight ovarian masses (55 episodes) in 49 non-neonatal patients treated from April 1984 to March 2017 were retrospectively analyzed. The Mann-Whitney U test and Fisher’s exact test were used for the statistical analysis.ResultsThe median age of these 55 episodes was 10.5 years old (range 1.0–23.0). Thirty-three patients presented with abdominal pain. Forty-five tumors and 13 cystic masses were resected and diagnosed pathologically (50 benign and 8 malignant). Torsion was identified in 15 cases (25.9%) at operation. The torsion masses were all benign, and 8 ovaries (53.3%) were successfully preserved. Comparing the torsion cases with the non-torsion cases, only the white cell count was significantly higher in the torsion cases (p=0.0133) and in the patients presented with abdominal pain (p=0.0068). The duration of abdominal pain was significantly shorter in ovary preserved cases than in oophorectomy cases.ConclusionThe white blood cell may be a helpful indicator of the presence of torsion as well as the need for surgery.
