MANDIBULAR SQUAMOUS CELL CARCINOMA IN A ROCK HYRAX ( PROCAVIA CAPENSIS)
Abstract:
A 9-yr-old, entire female captive rock hyrax ( Procavia capensis) was presented with a 1-wk history of sialorrhea. On clinical examination, a mass was identified, encompassing the rostral mandible and intermandibular area, with associated mucosal ulceration, marked gingival recession, and loosening or loss of adjacent teeth. Skull radiography and cytology of fine-needle aspirates of the mass were suggestive of squamous cell carcinoma. Based on a suspected poor prognosis, the animal was humanely euthanized. Postmortem histological examination of samples confirmed a diagnosis of oral squamous cell carcinoma with invasion of mandibular bone. Neoplasia is uncommonly reported in hyraxes, which has led to the assumption that they may share mechanisms of cancer resistance with elephants, their closest extant relatives. This is the first report of squamous cell carcinoma in this species.

What are Cells?
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...
