Soft tissue disorders are medical conditions affecting soft tissue. Soft tissue injuries are some of the most chronically painful and difficult conditions to treat because it is very difficult to see what is going on under the skin with the soft connective tissues, fascia, joints, muscles and tendons.
Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by the naked eye. [1] Microscopic anatomy is the study of minute anatomical structures assisted with microscopes , which includes histology (the study of the organization of tissues), [ 1 ] and cytology ...
Histologically, chronic sialadenitis can appear from unremarkable to a firm tan with expansion or atrophy of the lobular structure depending on the degree of inflammation and chronicity. Salivary stones (sialolith) may be evident with cystic dilation of the salivary ducts and periductal fibrosis. Mucus extravasation may also be observed.
Rheumatism [2] / ˈ r uː m ə t ɪ z əm / or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. [3] Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism".
They are situated just superficial to the submandibular salivary gland, and posterolateral to the anterior belly of either digastric muscle. [1]One gland, the middle gland of Stahr, which lies on the facial artery as it turns over the mandible, is the most constant of the series; small lymph glands are sometimes found on the deep surface of the submandibular gland.

Since cancer generally occurs more frequently in older people, this kind of lymphadenopathy is more common in older persons. [7] Metastatic lymph nodes tend to feel hard and may be fixed to underlying tissues and may or may not be tender. [7] Usually the lymph nodes that directly drain the area of the cancer are affected by the spread (e.g.
The dermis is composed of three major types of cells: [3] fibroblasts, macrophages, and mast cells.. Apart from these cells, the dermis is also composed of matrix components such as collagen (which provides strength), elastin (which provides elasticity), and extrafibrillar matrix, an extracellular gel-like substance primarily composed of glycosaminoglycans (most notably hyaluronan ...
