Diagnostic immunohistochemistry for canine cutaneous round

The expression of Iba1 is specific for canine cutaneous histiocytic tumours, and more sensitive than CD18. The utility of CD20 in the diagnosis of CCRCTs is limited Histiocytic sarcoma is an aggressive cancer in dogs. Different forms include localized histiocytic sarcoma, disseminated histiocytic sarcoma and hemophagocytic histiocytic sarcoma. Localized histiocytic sarcoma occurs most often in bones, joints, skin and lungs. Disseminated histiocytic sarcoma affects multiple organs/tissues at the same time

Canine cutaneous histiocytoma is a tumor of epi-dermal Langerhans' cell origin.17 Langerhans' cells in Prior IHC on one atypical histiocytoma was negative for T and B lym-phocyte markers and positive for MHC class II. A panel of monoclonal antibodies was applied to depar-affinized 4- m sections of each skin tumor. The primar histiocytoma, plasma cell tumor, dogs, immunohistochemistry, MUM1/IRF-4 The diagnosis of canine cutaneous round cell tumors may be difficult, and immunohistochemistry (IHC) is often required for diagnostic confirmation, particularly in situations where tumor morphology does not suffice for a final diagnosis base The histiocytic origin of the tumour cells was confirmed in 65 of the canine cutaneous histiocytomas and in 4 of the canine cutaneous histiocytic sarcomas. The tumours that had been misdiagnosed as canine cutaneous histiocytomas included plasmacytomas, epitheliotropic T-cell lymphomas and undetermined entities

detailed basic results of IHC analyses are presented in Table 2. Canine cutaneous histiocytoma was diagnosed in 27/60 tumours (45%), collected from dogs aged 8 months to 12 years (mean age: 6.4). The tumours were solitary except for one case (a 1.5-year old dog presented with multiple tumours localized within the pinna) Results. IHC analysis using a basic antibody panel revealed 27 cases of histiocytoma, one case of histiocytic sarcoma, 18 cases of cutaneous lymphoma of either T-cell (CD3+) or B-cell (CD79a+) origin, 5 cases of plas­macytoma, and 4 cases of mast cell tumours To determine the specificity of Iba1 as an immunohistochemical marker for canine and feline histiocytic proliferative, neoplastic and inflammatory disorders of the skin, we evaluated its expression in two types of histiocytic tumours, two non-neoplastic histiocytic proliferative conditions, one case of granulomatous dermatitis and four non-histiocytic tumours

Histiocytoma is a common, benign, cutaneous neoplasm of the dog. Cutaneous Langerhans cell histiocytosis (LCH) is well documented in humans.

  1. Cutaneous (reactive) histiocytosis is an uncommon condition of dogs. The condition is poorly described in the scientific literature and has various grades all of which may be found in one animal. Other names for the disease include sterile granuloma/pyogranuloma syndrome
  2. The immunohistochemical expression of the class A macrophage scavenger receptor CD204, was investigated in 50 canine histiocytic sarcomas (HSs) and compared with that of CD18, CD163, CD11d and class II molecules of the major histocompatibility complex (MHC)
  3. Histiocytoma is a common, benign, cutaneous neoplasm of the dog. Histiocytomas usually occur as solitary lesions, and usually undergo spontaneous regression
  4. Canine cutaneous histiocytoma. Clinical presentation--Canine cutaneous histiocytoma is a common, mostly benign neoplasm in young dogs. Breed or sex predilections are not observed. It mainly develops in young dogs, but may occur in older dogs. Typically, a solitary, plaque or dome-shaped small nodule, usually less than 2.5 cm in diameter, is.
  5. There are two primary differentials for a cutaneous histiocytic proliferation with numerous cutaneous/subcutaneous masses in dogs. The most frequent differential is cutaneous reactive histiocytosis, a disease that starts in the interstitial dendritic cell (IDC) and has a reactive pathologic process
  6. Canine histiocytoma is also a round cell tumor that contains a vacuolated cytoplasm , and so with these similar characteristics. It is possible that ETVT may be misdiagnosed as a histiocytoma by cytological and histological analyses without the LINE-c- myc based PCR assay, as seen in case 16 in this study ( Table 2 )
  7. It is only with a complete IHC panel that these tumors can be further subclassified in histiocytic sarcoma, cytokeratin-positive joint associated sarcoma, and malignant fibrous histiocytoma. The IHC panel that would be required for subclassification of joint associated sarcomas is reported in Table 1. Using this panel, tumors that express only.

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 tissues; thus the diagnosis is often one of exclusion. Clinical outcomes are generally poor, with. the skin called a cutaneous histiocytoma (Moore, 2014; Mastrorilli, 2012). Histiocytomas are small, benign lesions most commonly found in young dogs on the head and neck, specifically the pinna Canine and feline DCs express CD1a molecules, which together with major histocompatibility complex (MHC) class I and class II molecules, are responsible for presentation of peptides, lipids and glycolipids to T cells (Fig. 4). Hence, DCs are best defined by their abundant expression of molecules essential to their function as APC

Dogs with histiocytic sarcoma typically have non-specific signs, such as anorexia, weight loss, and decreased energy. Other signs depend on the organs involved and are usually a consequence of destructive mass formation. For example, if there is a large mass in the lungs, a dog may experience coughing or difficulty breathing Canine histiocytoma Histiocytoma is a common, benign, cutaneous neoplasm in dogs. Histiocytomas usually occur as solitary lesions, which spontaneously regress, and seldom recur. They can occur in dogs of all ages, but are more likely in dogs under three years of age

Cutaneous histiocytoma is one of the most frequently diagnosed skin tumors in the dog that commonly occurs in younger dogs with breeds like the boxer, English cocker spaniel, Doberman pinscher, and Scottish terriers (among others) overrepresented in diagnosed cases.3 Traditionally, histiocytomas are considered a benign lesion that will often. Getting the best out of your surgical biopsies - canine cutaneous histiocytoma. Cutaneous histiocytomas are very common, benign but rapidly growing neoplasms of epidermal dendritic cells known as Langerhans cells. Dendritic cells are antigen-presenting cells. They process antigens and present them on the cell surface to T-lymphocytes, and so.

BACKGROUND Histiocytoma is a common benign neoplasm of young dogs. Multiple histiocytomas are rare. Surgical or medical treatment of solitary tumours is not required in the majority of cases because the tumour usually undergoes spontaneous regression. Therapy is required when lesions are persistent, recurrent, ulcerated or in uncomfortable locations neous histiocytoma and histiocytic sarcoma (localized and disseminated forms) depending upon clinical behaviors and pathological features [6, 9, 19]. Canine histiocytic sarcoma (HS) included in HPDs, is a progressive and fatal malignant neoplasm that is mainly documented in middle-age to older purebred dogs, predomi Comparative Pathology of Canine Soft Tissue Sarcomas: Possible Models of Human Non-rhabdomyosarcoma Soft Tissue Sarcomas IHC slides was performed following completion of coma (n ¼ 1) and malignant fibrous histiocytoma (n ¼ 1). Six of these seven tumours were considered high grade (based on cellular morphology, hig immunohistochemistry (IHC) has been considered a necessary part of the diagnostic scheme in canine HM [12]. The most comprehensive diagnostic scheme for HM has been based on IHC staining with CD1 and CD11c (indicative of cells derived from the dendritic lineage), CD18 and CD45 (pan-leukocyte markers

Canine cutaneous histiocytoma (CCH) is a common benign skin tumour originating from epidermal Langer-hans cells. These tumours often display spontaneous regression and therefore represent a valuable animal model for investigation of tumour regression. Based on previous studies it was hypothesized that up Positive control consisted of a partially pigmented canine conjunctival melanoma for Melan A and S‐100, and a canine globe diagnosed as an uveodermatologic syndrome for CD18. Negative controls were prepared by using antibody diluent (Dakocytomation) in place of the primary antibodies in each IHC procedure Osteosarcoma is a mesenchymal tumor having evidence of osteoid or bone production by malignant stromal cells in some portion of the tumor. Bizarre tumor cell morphology and divergent differentiation are common. 1, 2, 6 The histologic diagnosis of OS rests solely upon demonstration of unequivocal osteoid being laid down by malignant cells Macrophage and Histiocytoma Marker Antibody (D11) Summary. In Western blotting, it detects an antigen of 125kDa in human liver and 135kDa in tumors of histiocytic origin. Comparative study of this MAb and a standard CD68 MAb showed that their antigens are different

  1. Three of the 8 HS dogs could be identified by excisional biopsy, and the remaining 5 dogs were identified as primary lung HS at necropsy. Finally, 18 of the 30 HS dogs were established by IHC staining using an antibody‐targeting MHC class II, and the remaining 12 HS dogs were established using anti‐CD18 antibody
