Histiocytic sarcoma (HS) represents a rare type of malignant disease, characterized by neoplastic proliferation interstitial dendritic cells (iDCs). In rabbits, there are only two previous reports HS with pulmonary and cutaneous primary localizations. A 2-year-old, male, European rabbit (Oryctolagus cuniculus) clinical history chronic respiratory distress progressive weight loss was necropsied....

Kikuchi-Fujimoto disease (KFD), also known as Kikuchi’s or histiocytic necrotising lymphadenitis, is a rare and benign medical condition of unknown aetiology. It often misdiagnosed lymphoma systemic lupus erythematosus (SLE), leading to inappropriate investigations delayed treatment. thus important for clinicians be cognizant this when assessing patients with cervical lymphadenopathy.

Histiocytic sarcoma is a malignant neoplastic proliferation of atypical histiocytes with tendency to spread, characterized by fast progression to disseminated form--disseminated histiocytic sarcoma. Cytopathology is a low, invasive, cheap, and quick method of diagnosis commonly used in veterinary oncology. The aim of the presented study was description of cases of visceral histiocytic sarcomas ...

Juvenile xanthogranuloma is a relatively uncommon, benign histiocytic proliferative disorder. A case of juvenile xanthogranuloma in a 13-month-old girl with an unusual clinical form is described. She presented with a yellow-red projecting nodule over the helical rim of her right ear. The lesion was histologically diagnosed as juvenile xanthogranuloma after excisional biopsy. Although primarily ...

In this issue of Blood, Hervier et al has identified that cooccurrence of Langerhans cell histiocytosis (LCH) and Erdheim-Chester disease (ECD) in the same patient is not a rare event. Mixed histiocytosis (MH) highlights existence of a link between distinct groups of histiocytic disorders and suggests presence of a common progenitor cell. Today, histiocytic disorders are classified into 3 group...

Background: Multicentric reticulohistiocytosis (MRH) is a rare histiocytic proliferative disorder involving skin, mucosa and joints. Diagnosis is confirmed by histopathological examination. Case Report: A 45 year old patient presented with non-pruritic papules over the body and multiple joint pains. Histopathologically, the lesion was composed of oncocytic macrophages and multinucleate giant ce...

The diagnosis based on histological and immunohistochemical analysis lymph node biopsy. article presents four clinical cases disease. According to results primary tissue three patients were misdiagnosed with lymphoma. due unusual for lymphoid malignancy course material was revi...

Although synovial cell sarcoma is reported to be the most common neoplasm of the canine synovium, this retrospective study of 35 canine synovial tumors found that the majority were of histiocytic origin. Five (14.3%) synovial cell sarcomas were identified by positive immunohistochemical staining with antibodies to cytokeratin. Eighteen (51.4%) histiocytic sarcomas were identified by cell morpho...
