ABSTRACT: Avipoxvirus is the etiological agent of the avian pox, a well-known disease of captive and wild birds, and it has been associated with tumor-like lesions in some avian species. A white-faced whistling duck (Dendrocygna viduata) raised in captivity was referred to a Veterinary Teaching Hospital in Northeast due to cutaneous nodules present in both wings. A few days after the clinical examination, the animal died naturally. Once submitted to necropsy, histopathological evaluation of the lesions revealed clusters of proliferating epithelial cells expanding toward the dermis. Some of these cells had round, well-defined, intracytoplasmic eosinophilic material suggestive of poxvirus inclusion (Bollinger bodies). PCR performed on the DNA extracted from tissue samples amplified a fragment of the 4b core protein gene (fpv167), which was purified and sequenced. This fragment of Avipoxvirus DNA present in these tumor-like lesions showed high genetic homology (100.0%) with other poxviruses detected in different avian species in several countries, but none of them were related to tumor-like lesions or squamous cell carcinoma. This is the first report of Avipoxvirus detected in tumor-like lesions of a white-faced whistling duck with phylogenetic analysis of the virus.

ZusammenfassungEin 3-jähriges Mädchen erlebte eine 15 Monate andauernde Odyssee, ehe durch eine radikale Operation eines Osteoid-Osteoms am Daumenendglied rechts Schmerzfreiheit erreicht werden konnte. Das Osteoid-Osteom ist ein gutartiger Knochentumor, zählt zu den Tumor-like Lesions, kommt an der Hand sehr selten vor und ist in der uns zur Verfügung stehenden Literatur noch nie bei einem Kleinkind beschrieben worden. In einer der ersten Röntgenuntersuchungen wurde in den Weichteilen des rechten Daumens ein Fremdkörper gefunden und somit ein Trauma als Schmerzursache angenommen.Zahlreiche v. a. röntgenologische Untersuchungen, unterschiedliche Diagnosen und Therapien sowie der gesteigerte Schmerzmittelbedarf wurden zusammengefasst. Der monatelang ruhig gestellte Daumen wurde erst nach dem letzten chirurgischen Eingriff langsam wieder im täglichen Leben eingesetzt.Diese Publikation soll das seltene Auftreten dieses Tumors bei einem Kleinkind sowie die Wichtigkeit einer interdisziplinären Zusammenarbeit (ggf. unter Einbeziehung digitaler Medien) hervorheben – zum Wohle der Patienten und zur Einsparung von Ressourcen.

Breed predispositions to canine digital neoplasms are well known. However, there is currently no statistical analysis identifying the least affected breeds. To this end, 2912 canine amputated digits submitted from 2014–2019 to the Laboklin GmbH & Co. KG for routine diagnostics were statistically analyzed. The study population consisted of 155 different breeds (most common: 634 Mongrels, 411 Schnauzers, 197 Labrador Retrievers, 93 Golden Retrievers). Non-neoplastic processes were present in 1246 (43%), tumor-like lesions in 138 (5%), and neoplasms in 1528 cases (52%). Benign tumors (n = 335) were characterized by 217 subungual keratoacanthomas, 36 histiocytomas, 35 plasmacytomas, 16 papillomas, 12 melanocytomas, 9 sebaceous gland tumors, 6 lipomas, and 4 bone tumors. Malignant neoplasms (n = 1193) included 758 squamous cell carcinomas (SCC), 196 malignant melanomas (MM), 76 soft tissue sarcomas, 52 mast cell tumors, 37 non-specified sarcomas, 29 anaplastic neoplasms, 24 carcinomas, 20 bone tumors, and 1 histiocytic sarcoma. Predisposed breeds for SCC included the Schnauzer (log OR = 2.61), Briard (log OR = 1.78), Rottweiler (log OR = 1.54), Poodle (log OR = 1.40), and Dachshund (log OR = 1.30). Jack Russell Terriers (log OR = −2.95) were significantly less affected by SCC than Mongrels. Acral MM were significantly more frequent in Rottweilers (log OR = 1.88) and Labrador Retrievers (log OR = 1.09). In contrast, Dachshunds (log OR = −2.17), Jack Russell Terriers (log OR = −1.88), and Rhodesian Ridgebacks (log OR = −1.88) were rarely affected. This contrasted with the well-known predisposition of Dachshunds and Rhodesian Ridgebacks to oral and cutaneous melanocytic neoplasms. Further studies are needed to explain the underlying reasons for breed predisposition or “resistance” to the development of specific acral tumors and/or other sites.

Abstract Objectives Chorioangiomas (CAs) are the most frequent tumor-like-lesions of the placenta. Giant CAs (more than 4–5 cm in diameter) is rare and may result in severe maternal fetal complications. Case presentation A 38-year-old multigravida presented at 31 weeks’ gestation with contractions. Upon evaluation, contractions were spontaneously ceased, and the cervix was closed. Ultrasound examination revealed a single viable fetus, polyhydramnios and a 75 x 48 x 82 mm vascular lesion located on the placental surface near the cord insertion. Doppler assessment was suggestive of fetal anemia with middle cerebral artery-peak systolic velocity (MCA-PSV) 1.8 MoM’s. Fetal heart rate monitoring and biophysical scores were reassuring. Following betamethasone fetal cord sampling that revealed fetal hemoglobin level of 8.8 g/dL, 57 cc of blood was transfused resulting in final hemoglobin level of 14.3 g/dL measured prior to needle extraction. MCA-PSV was normalized immediately after the procedure, however aggravated at the following day with MCA-PSV 65 cm/s (1.46 MoM’s). No other intervention was taken and MCA-PSV continued to fluctuate from slight to severe anemia spontaneously over a period of two weeks. At 34 gestational weeks, the women delivered a healthy baby. Fetal hemoglobin level at delivery was 21 g/dL. Conclusions Fetal blood transfusion is a reasonable treatment for fetal anemia in cases of giant chorioangiomas. Following transfusion, MCA-PSV may act unexpectedly reflecting various mechanisms affecting the flow.

AbstractBackground: CERAMENT™|BONE VOID FILLER is an injectable and moldable ceramic bone substitute material intended for bone voids. The material consists of hydroxyapatite and calcium sulfate hemihydrate. The aim of this study is to present the first long-term results following open curettage of benign bone tumors and tumor-like lesions and void filling with this novel injectable and synthetic bone graft. Methods: Thirty three patients were enrolled into the study between June 2013 and October 2014 .Totally, we treated 24 women and 9 men with a median age of 47 years (range: 22-74). All patients suffered from primary musculoskeletal system disorders (enchondroma 63,6%, giant cell tumor 18%, aneurysmal bone cyst 9%, fibrous dysplasia 9%, Gaucher disease 3%). We performed curettage of pathological lesions, then the bone substitute was administered by means of needle to the void. Results: The average follow-up was 13 months (range: 2-13 months, median 10 months). No metastasis or recurrence had been detected. We received significant clinical improvement relating to VAS, MSTS, and oncological results. Conclusions: The results of our study report that CERAMENT can be successfully used as a bone substitute in patients with various bone diseases, as well as benign bone tumors. CERAMENT can provide an effective and long-term solution for reconstructive procedures following curettage of bone tumors and tumor like lesions.
