How can a histiocytoma be diagnosed?
Accurate diagnosis relies upon microscopic examination of tissue.
Depending on the location, your veterinarian may recommend one or more methods of obtaining a tissue sample for diagnosis.
The most common methods include needle aspiration, punch biopsy, and full excision biopsy (removing the growth)..
What are histiocytoma cells on cytology?
On cytology, histiocytomas are in the round cell tumor category.
They may be confused with other round cell tumors, such as plasma cell tumors or poorly granulated MCTs..
What are the characteristics of histiocytoma?
Histiocytoma in dogs typically appear as small, solitary, hairless lumps, usually on the head, neck, ears, and limbs.
In some uncommon cases (in the case of Shar peis, in particular), multiple masses may be present simultaneously..
What cells are histiocytomas?
A histiocytoma is a tumor that contains histiocytes (normal immune cells).
Histiocytes are located in many parts of your body, including your bone marrow, blood stream, skin, lungs, liver, spleen and lymph nodes.
Sometimes, histiocytes travel to tissues where they're not normally found and cause tumors (histiocytomas)..
What is a cytology of skin tumors?
Usually cytological examination can still arrive at the diagnosis, provided that there are enough characteristic cells present.
Several skin tumours are characterized cytologically by a uniform population of round tumour cells that have little or no apparent connection with each other..
What is the cytological appearance of a histiocytoma?
The indented nucleus (arrow) of a round cell, along with the light blue cytoplasm, stippled chromatin and indistinct borders (compared to plasma cells) are typical of a histiocytoma.
This particular aspirate lacks the blue background that can be seen in many smears from these lesions (Wright's stain, 100s objective).Aug 2, 2020.
