Pituitary gland tumors are very common in the canine. A productive form arising from the anterior pituitary is the primary cause of Cushing's disease of dogs. This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of ...
For inoperable tumors, treatment with tyrosine kinase inhibitors may be attempted. In general, the prospect of cure is best in well-differentiated mastocytomas (low-grade or grade 1) and in animals without general signs (substages a). [18] Young dogs (<1 year of age) also have a better prognosis than older dogs. [29]
Some dog owners opt for no treatment of the cancer at all, in which case palliative care, including pain relief, may be offered. Regardless of how treatment proceeds following a diagnosis, the quality of life of the pet is an important consideration. In cases where the cancer is not curable, there are still many things which can be done to ...
Most commonly histiocytomas are found in young dogs and appear as a small, solitary, hairless lump, [6] although Shar Peis may be predisposed to multiple histiocytomas. [7] They are most commonly found on the head, neck, ears, and limbs, and are usually less than 2.5 cm in diameter. [8] Ulceration of the mass is common.
Canine transmissible venereal tumors are histiocytic tumors that may be transmitted among dogs through coitus, licking, biting and sniffing tumor affected areas. The concept that the tumor is naturally transmissible as an allograft came from three important observations. First, CTVTs can only be experimentally induced by transplanting living ...
The multilobular tumour of bone (MTB), also called an osteochondrosarcoma, is the most common tumour of the canine skull, [1] although it is relatively rare in general.. MTB usually presents as a firm, circumscribed and generally slowgrowing bone tumour in older dogs from medium or large breeds.
This list of crinoid genera is an attempt to create a comprehensive listing of all genera that have ever been considered to be crinoids, ...
Articulata are a subclass or superorder within the class Crinoidea, including all living crinoid species. They are commonly known as sea lilies (stalked crinoids) or feather stars (unstalked crinoids). The Articulata are differentiated from the extinct subclasses by their lack of an anal plate in the adult stage and the presence of an ...
