Exudation cysts arise from the distension of cavities which are not provided with excretory ducts, such as those in the thyreoid. Implantation cysts are caused by the accidental transference of portions of the epidermis into the underlying connective tissue, as may occur in wounds by needles, awls, forks, or thorns. The implanted epidermis proliferates and forms a small cyst.
The snowfields melt into mud and within days a jungle stretches high into the air. Everything grows, swells, proliferates. Plants climb on top of plants, fighting for the life-energy of the sun. Everything is eat and be eaten, grow and thrive in that short season. Because when the first snow of winter falls again, ninety per cent of the year must pass until the next coming of warmth.
The cartilage of the epiphysial disc proliferates actively and irregularly, so that it becomes softer, thicker, and wider, and gives rise to a visible swelling, best seen at the lower end of the radius and lower end of the tibia, and at the costo-chondral junctions where the series of beaded swellings is known as the "rickety rosary."
The synovial membrane proliferates, grows over the cartilage, and replaces it, and when two such articular surfaces are in contact they tend to adhere, thus obliterating the joint, cavity, and resulting in fibrous or bony ankylosis. Clinical Features.
In many cases in our returns repression is so potent from long practice, that the sweetest smile, the kindest remarks or even deeds are used either to veil it to others, or to evict it from our own consciousness, or else as a self-inflicted penance for feeling it, while in some tender consciences its checked but persistent vestiges may become centers of morbid complexes and in yet other cases it burrows and proliferates more or less unconsciously, and finds secret and circuitous ways of indulgence which only psychoanalysis or a moral or religious confessional could trace.
