A hard corn is called a heloma durum, while a soft corn is called a heloma molle. The location of the soft corns tends to differ from that of hard corns. Hard corns occur on dry, flat surfaces of skin. Soft corns (frequently found between adjacent toes) stay moist, keeping the surrounding skin soft. The corn's center is not soft however, but ...
Pressure corns usually occur on thin or glabrous (hairless and smooth) skin surfaces, especially on the dorsal surface of toes or fingers, but corns triggered by an acute injury (such as a thorn) may occur on the thicker skin of the palms (palmar corns) or bottom of the feet (plantar corns).
Corns and calluses are very common and do not look pleasant. Corns and calluses generally need treatment only if they cause problems. For most people, the best treatment of corns and calluses is to eliminate the source of friction or pressure. [5] Ingrown toe nail is a disorder where the nail starts to grow into the soft fleshy area of the toe.
Cutaneous horns, also known by the Latin name cornu cutaneum, are unusual keratinous skin tumors with the appearance of horns, or sometimes of wood or coral. Formally, this is a clinical diagnosis for a "conical projection above the surface of the skin."
An extraskeletal chondroma often manifests clinically as a nodular soft tissue mass that steadily enlarges without discomfort and may exist for varying lengths of time before diagnosis. [2] The fingers and toes are the most often affected areas. [3] The tumor is oval in shape and clearly defined; it rarely has a diameter more than 3 cm. [4]
It is roughly the same with finger pads — in animals with an anatomical abnormality, part of the pad is not in contact with rubbing surfaces and excessive keratin deposition is formed. The idiopathic form of nasodigitic hyperkeratosis in dogs develops from unknown causes and is more common in older animals (senile form).
Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve, most commonly of the second and third intermetatarsal spaces (between the second/third and third/fourth metatarsal heads; the first is of the big toe), which results in the entrapment of the affected nerve.
These pads act as a cushion for the load-bearing limbs of the animal. The paw consists of the large, heart-shaped metacarpal or palmar pad (forelimb) or metatarsal or plantar pad (rear limb), and generally four load-bearing digital pads, although there can be five or six toes in the case of domestic cats and bears (including giant panda).
