Skin tumors: Benign tumors
Elderly Warts: These are wart-like keratotic formations in adults, located on the back, chest, shoulders, and less often on the forehead, face, arms, head. Elliptical spotted formations.

Elderly Warts (Verrucae seniles s. Seborrhoicae)
These are wart-like keratotic formations in adults, located on the back, chest, shoulders, and less often on the forehead, face, arms, head. Elliptical spotted formations. Some of them can rise more, furrow, partly pedicule. All are covered with a greasy squamous and layered horny layer.
Such senile warts can be combined with mollusk and pigmented nevi. Therefore, some consider them to be particularly late nevi.
Unlike senile keratomas, these warts never degenerate malignantly.
Treatment consists of their removal by electrocoagulation, galvanic knockout, curettage and surgical removal.
It is a solid fibrous formation with a dark color, the round shape of a tablet, very slightly raised, fused to the skin, clearly limited, 1 cm in diameter. When pressed, it is hard-fibrous, non-disappearing, and there is a pink or anemic circle around it. It is rare, especially on the outer sides of the thighs, armrests, usually singly, and sometimes several in number.
The diagnosis is quite difficult because such a fibroid resembles a verrucous or pigmented nevus, some histiocytomas or melanomas.
The education is benign and painless. It can be removed surgically.
Single skin fibroids are very rare. Their sizes can be different. They are solid pink formations with a typical histological structure.
Lipomas are common benign formations of subcutaneous adipose tissue. They are single or multiple and are localized mainly on the outer limbs and neck. They can range in size from lentils to hens’ eggs. Their consistency is pasty, slightly fused with the skin, semi-mobile and vaguely limited in depth and sideways. They develop in people prone to such formations.
They are easy to diagnose and of some interest and difficulty with some oleomes, paraffins, Darier-Roussy subcutaneous sarcoids, tuberculous subcutaneous gums, and some luteal sclerofibrous cellulitis and rheumatismus cutis nodosum.
Nevi are congenital or inherited malformations in the form of spots or tumors on the skin and mucous membranes. Sometimes they are established at birth, in early childhood, and others are formed in old age. Once formed, most of them remain as the final malformative scar. Very rarely, some special forms may gradually decrease and even disappear, while others may become larger and change.By number they can be single and multiple, and by location – scattered or grouped. There is hardly a person without such malformations in some form on his skin. More often, nevi or nevus diseases are congenital. Combined in large numbers and different forms, skin nevi can be combined with malformations of other organs and systems (eyes, nervous system, internal organs), general dystrophy. Degeneration, idiocy, endocrine disorders and others.
Etiology and pathogenesis. For most of the neural malformations and diseases, they are not fully understood. In some of them the importance of influences and influences of pathogenic factors on the germ cells stands out. In others, pathogens are involved during embryonic life. Some late-onset nevi may be explained by residual embryonic cell wells. These possibilities gave rise to various theories to explain the genesis of this type of malformation (trauma, pressure, fissure effects, inflammation, dysembryoplasia or agenesis of the sympathetic and ganglia, etc. during embryonic life). None of them so far can fully explain the pathogenesis of all forms.
Nave pigments. Pigmented nevi are dark brown or black spots or dense skin formations depending on the accumulation of melanin or special cell proliferation overloaded with pigment. Such nevi, in addition to the skin, can be found in some areas of the central nervous system, meninges and eye.
