MCH is an uncommon, progressive disease of dogs. There are very few reports on MCH, which are both in wide age range and in different species. This syndrome of multiple, persistent and recurrent MCH can be documented under LCH, as the condition LCH in humans2. In one study, histiocytic cells were found to originate from Langerhans cells. There is no difference in the immunophenotypic features of the CH and LCH, and CD1a can be used for the detection of histiocytic diseases. Likewise, CD1a was found positive in this case and was found compatible with the MCH, as well as LCH. The positive effect of lomustine on histiocytic tumors has been previously reported for the treatment of MCH. In this case, effective treatment could not be obtained with corticosteroids. So that treatment was continued with lomustine and its successful effect was confirmed in the treatment of MCH.
Oral malign melanoma is the most commonly diagnosed tumor in the oral cavity of dogs. Successful results for BRAF gene mutations have been achieved in human medicine in the diagnosis of this neoplasia and in targeted treatment attempts. In this case report, it is aimed to present the prognostic evaluation of the patient who was detected to be BRAF V600E immunopositive.
Canine oral papilloma is a benign tumor of young dogs and caused by papillomavirus. The possible role of papillomavirus infection in the development of oral squamous cell carcinoma has recently been studied, but it has not been elucidated in veterinary medicine yet.
Peripheral giant cell granuloma is one of the non neoplastic pathological conditions of gingiva and is a very rare condition encountered in pet animals. Histopathology is the diagnostic tool to eliminate similar lesions. The aim of this case report was to present this rare condition and its marked remission by radiotherapy and zoledronic acid (ZA) administration.
Hibernoma is a very rare benign tumor of brown fat tissue which is found in hibernating and non-hibernating mammals. Until now, it has been reported in rats, dogs, and human beings. In this case report, a thirteen-year-old, spayed, female Siamese cat was examined for intestinal motility disorder.
Cutaneous histiocytoma (CH) is a very common benign neoplasm of young dogs, but multiple cutaneous histiocytomas (MCH) have rarely been encountered in dogs and have mainly been reported in Shar-pei breeds. Since the clinical prognosis of the disease is different from CH, MCH is found similar to cutaneous Langerhans cell histiocytosis (LCH) in humans.
Canine transmissible venereal tumor (TVT) is a tumoral disease which begins in the genital area as a contagious disease and spreads to other parts of the body and can be observed in the skin and as distant metastasis and its the cellular origin is unknown.
Well-differentiated adipose liposarcomas are among the rare malignant tumors. In this work, we define a well-differentiated subcutaneous liposarcoma showing infiltration to bone and muscle on a 10 year old, mixed breed, female dog’s lumbar region.
Urinary bladder tumors in cats, unlike in dogs, usually appear outside of the trigonal region. These tumors are confused with urinary tract infections associated with hematuria in a clinical sense. Cytological examination and ultrasound (USG) imaging techniques are very valuable, but histopathological approach is the golden key.
Lymphoid neoplasia are a heterogenous tumor group with contradictory clinical appearances and inconsistent prognoses and treatments. B and T lymphomas are seen in dogs at a %0.33 rate which is considered a model of Non-Hodgkin lymphoma in people.
