As the muscles and bones have a richer blood supply than the integument, the death of skin and subcutaneous tissues extends higher than that of muscles and bone, with the result that the stump left after spontaneous separation is conical, the end of the bone projecting beyond the soft parts. Clinical Features.
When other means fail, the use of an exploring needle clears up the diagnosis. Mixed Nævus. As its name indicates, the mixed nævus partakes of the characters of the other two varieties; that is, it is a subcutaneous nævus with involvement of the skin. It is frequently met with on the face and head, but may occur on any part of the body.
When deformity results from depression of a scar, as is not uncommon after the healing of a sinus, the treatment is to excise the scar. Depressed scars may be raised by the injection of paraffin into the subcutaneous tissue. Painful Scars. Pain in relation to a scar is usually due to nerve fibres being compressed or stretched in the cicatricial tissue; and in some cases to ascending neuritis.
From neglect of cleanliness, the skin becomes the seat of eczema or even of ulceration attended with foul discharge. Samson Handley has sought to replace the blocked lymph vessels by burying in the subcutaneous tissue of the swollen part a number of stout silk threads lymphangioplasty.
Owing to the swelling and condensation of the parts around, the pus thus formed is under considerable pressure, and this causes it to burrow along the lines of least resistance. In the case of a subcutaneous abscess the pus usually works its way towards the surface, and "points," as it is called.
But he was quite prepared not to be any the worse. This was, however, not subcutaneous, with him. He said it to himself, quite openly. His concealment of himself from himself turned on a sort of passive resistance he was offering to a growing reluctance to hear a negative to his application.
Small shot fired at longer ranges over about a hundred and fifty feet usually go through the skin, but seldom pierce the fascia, and lie embedded in the subcutaneous tissue, from which they can readily be extracted.
On section, it presents the appearance of a finely reticulated sponge. Although it may be noticed at, or within a few days of, birth, a subcutaneous nævus is often overlooked, especially when on a covered part of the body, and may not be discovered till the patient is some years old.
They also occasionally have an associate muscular development in the subcutaneous tissues similar to the panniculus adiposus of quadrupeds, giving them preternatural motile power over the skin. The man recently exhibited under the title of the "Elastic-Skin Man" was an example of this anomaly.
The bruising of the vessel wall, especially if it is diseased, may result in the formation of a thrombus which occludes the lumen temporarily or even permanently, and in rare cases may lead to gangrene of the limb beyond. #Subcutaneous Rupture.# An artery may be ruptured subcutaneously by a blow or crush, or by a displaced fragment of bone.
