Definition
Tiloma is a circumscribed thickening of the skin (hyperkeratosis), which can be relatively extended or very circumscribed (approximately the size of a lentil).
This lesion generally involves small surfaces, but tends to extend in depth, compressing the connective tissue of the dermis and atrophying the elastic tissue; unlike common callosities, tiloma causes spontaneous or pressure pain. Sometimes, in deep hyperkeratosis, entrapment of dermal nerve and / or vascular terminations may occur.
The tiloma is an alteration of a reactive nature, ie it represents a response to the perpetuation of local insults. In fact, like the bladders or calluses, these lesions are formed by mechanical traumas, such as repeated pressure, rubbing or friction.
In most cases, tilomas appear at the level of the feet, at the plantar surface, at the interphalangeal joints of the fingers or at bony prominences (eg, calcaneus, metatarsal heads, etc.).
A tiloma can arise as a reaction to the excessive constriction of uncomfortable footwear and sports activities, especially if carried out on rough terrain (eg running or walking). These injuries can also result from a defect in posture or an incorrect way of walking.
