A 4-year old, primiparous, female Anatolian Shepherd dog was presented for evaluation of type II vaginal prolapse with alopecia of the left perineal skin. Hematological analyses demonstrated leukocytosis and thrombocytopenia. Estradiol (E2) and progesterone (P4) levels were 156 pg/mL and 2.3 ng/mL, respectively. The vaginal smear was predominantly (at least 80%) made up of anuclear superficial cells. An abdominal ultrasonography revealed a heterogeneous multicystic mass with anechoic areas adjacent to the caudal pole of the left kidney. An ovariohysterectomy was performed. Ten days after the surgery, the prolapsed vagina was completely regressed. A histopathological examination of the ovarian mass demonstrated …

The patient in this study was a 20-year-old thoroughbred gelding. After clinical and radiographical assessments, a bilateral rostral mandibular body fracture was determined. Fracture stabilization was achieved via a bilateral interfragmentary cerclage wire application. The horse started to use its jaw within 24 h of surgery. Postoperative radiographs were taken until month 6, at different periods, and fracture healing was evaluated. Fixation materials were left in place. Fracture healing occurred with a rostral part malocclusion. The purpose of this study was to give clinical information about mandibular fractures and treatment of these fractures in a horse.

Unusual Anal Atresia In A Lamb, Siavash Ahmadi Noorbakhsh
Turkish Journal of Veterinary & Animal Sciences
The first report of an unusual anal atresia with growth of ectodermal organs (wool and skin) in the shape of the intestine inside the body is provided here. During reconstructive surgery, a rectum-like structure was noted, in which wool strands grew densely. A hypothetical mechanism by which this structure formed is presented on the basis of local alterations in fetal tissue proliferation and rate of development.

Congenital Lymphoma Of B-Cell Lineage In A Newborn Calf, Enver Beytut, Burhan Özba
Turkish Journal of Veterinary & Animal Sciences
In this report, congenital lymphoma of B-cell lineage in a Brown Swiss calf is described. A large mass was seen on the head of the calf at birth. At necropsy, multiple masses were found on the skin and internal organs. A histopathological examination showed atypical lymphoid cells separated by connective tissue. None of the tumor cells showed a positive reaction to CD3, but the cells were immunopositive for CD79\alphacy. A CD45+ reaction confirmed a hematopoietic origin of the neoplasm. Tumor cells were also positive for lambda light chain IgG (\lambda IgG). Proliferating cell nuclear antigen (PCNA) immunostaining showed diffuse nuclear …
