BACKGROUND
Histiocytic sarcoma (HS) is a rare but aggressive malignancy in humans that is poorly responsive to existing treatments. Although rare in most breeds of dogs, HS is common in Bernese mountain dogs (BMDs).
OBJECTIVE
Determine risk factors associated with development of HS in BMD.
METHODS
A
A 6-year-old Bernese Mountain dog was presented with a history of lethargy and weight loss of 2 weeks duration. On physical examination the dog had pale mucous membranes and tachypnea. Ultrasound examination revealed hepatomegaly, splenomegaly, and mesenteric lymphadenomegaly. Results of a CBC
Histiocytic sarcoma (HS) is an aggressive malignant neoplasm of dendritic cell origin that is common in certain breeds of dogs. High prevalence of fatal, disseminated HS has been described in Bernese Mountain Dogs (BMDs). Support for genetic predisposition to develop HS has been presented in several
A 6-year-old neutered female Bernese mountain dog is described with anorexia, weight loss and melena. Gastric neoplasia was noticed (on ultrasound) and pathological examination ofgastric biopsies showed a histiocytic tumor. Necropsy confirmed the diagnosis of a localised histiocytic sarcoma. It was
A 7-year-old female neutered Bernese mountain dog was presented in a semi-comatose state. Based on serum hypo-osmolality with inappropriate urine hyper-osmolality and urine sodium excretion, the dog was diagnosed with a syndrome of inappropriate antidiuretic hormone secretion secondary to a
Canine histiocytic sarcoma (HS) is a rare neoplasm that originates from dendritic cells or macrophages, and there have been a number of cases experienced in Japan. To identify the characteristics and prognostic variables that determine outcome in dogs with HS in Japan, medical records of 73 dogs
Histiocytic sarcoma affecting the central nervous system (CNS HS) in dogs may present as primary or disseminated disease, often characterized by inflammation. Prognosis is poor, and imaging differentiation from other CNS tumors can be problematic.To Histiocytic sarcoma is a rare disorder in humans, however it is seen with appreciable frequency in certain breeds of dogs, such as Bernese mountain dog. The purpose of this study was to fully characterize a novel canine histiocytic sarcoma cell line, and utilize it as a tool to screen for potential
BACKGROUND
Histiocytic malignancies in both humans and dogs are rare and poorly understood. While canine histiocytic sarcoma (HS) is uncommon in the general domestic dog population, there is a strikingly high incidence in a subset of breeds, suggesting heritable predisposition. Molecular cytogenetic
With recent improvements in therapeutic procedures and prolongation of survival, the incidence of cardiac metastasis is likely to increase. The aim of the current study was retrospectively to analyze cases of atrial metastases detected by echocardiography at our center. We report on a series of 10
Two routinely used antikeratin monoclonal antibodies, AE1:AE3 (Hybritech Inc., La Jolla, CA) and CAM-5.2 (Becton-Dickinson, Mountain View, CA), were compared with a new antikeratin monoclonal antibody mixture, MAK-6 (Triton Biosciences, Inc., Alameda, CA). Various poorly differentiated epithelial
Canine histiocytic malignancies (HM) are aggressive tumors that occur with particularly high frequency in certain breeds including Bernese mountain dogs and flat-coated retrievers. Robust diagnosis of HM commonly utilizes immunohistochemical stains that are broadly ineffective on formalin-fixed
Canine histiocytic malignancies (HM) are rare across the general dog population, but overrepresented in certain breeds, such as Bernese mountain dog and flat-coated retriever. Accurate diagnosis relies on immunohistochemical staining to rule out histologically similar cancers with different
