Canine histiocytic neoplasia
Histiocytic sarcoma complex The histiocytic sarcoma complex of the dog , which includes both localized and disseminated histiocytic sarcoma , comprises malignant diseases characterized by infiltration of neoplastic histiocytes, most frequently observed in middle-aged Bernese mountain dogs (often with a familial association), rottweilers, flat-coated retrievers, and golden retrievers (14 ...
ABSTRACT: Histiocytic sarcomas have been described in veterinary medicine since 1980, but studies on the subject are still scarce. Based on this, the objective of this article is to describe the epidemiological, anatomopathological and immunohistochemical aspects of histiocytic sarcoma in dogs submitted to necropsy in a diagnostic service covering the midwestern region of Rio Grande do Sul ...

In dogs , histiocytic sarcoma (HS) is a malignant neoplasm of interstitial dendritic cell or macrophage origin. Although this neoplasm has the potential to arise from various tissues in which dendritic cells reside, the most common sites of primary HS are the spleen, lymph nodes, lungs, bone marrow, CNS, skin, subcutis, and periarticular and ...
Synovial Histiocytic Sarcoma in a Dog
ABSTRACT Background: Histiocytic sarcoma is a malignant tumor that commonly affects large-breed, middle-aged dogs in the form of solitary masses that may affect joints and other organs. The imaging findings (radiography, ultrasound and elastogra-phy) of synovial histiocytic sarcoma correlated with cytological, histopathological and immunohistochemical tests are still poorly described in the ...
Histiocytic sarcoma is a highly aggressive malignant cancer arising from histiocytes, immune cells present throughout the body. It occurs more frequently in certain dog breeds such as Bernese Mountain Dogs , Rottweilers, and Flat-Coated Retrievers. The disease can originate in a single site—such as the lung, spleen, liver, or periarticular tissues—or be disseminated at diagnosis. Clinical ...

Abstract Histiocytic sarcoma (HS) refers to a highly aggressive and frequently disseminated neoplastic disease belonging to the class of canine histiocytic proliferative disorders. Disseminated HS (previously called malignant histiocytosis) is highly breed specific, with Bernese mountain dogs (BMDs), rottweilers, and retrievers having a high prevalence with a frequency of approximately 25% in ...
In dogs and cats, histiocytic sarco-mas (HS) arise from interstitial DCs that occur in most tissues of the body. Histiocytic sarcomas begin as localized lesions, which rapidly disseminate to many organs. Primary sites include spleen, lung, skin, brain (meninges), lymph node, bone marrow, and synovial tissues of limbs.
