Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

Impingement of the shoulder was previously thought to be precipitated by shoulder abduction and surgical intervention focused on lateral or total acromionectomy. [4] [25] In 1972, Charles Neer proposed that impingement was due to the anterior third of the acromion and the coracoacromial ligament and suggested surgery should be focused on these ...
This sensation of air under the skin is known as subcutaneous crepitation, a form of crepitus. Numerous etiologies of subcutaneous emphysema have been described. Pneumomediastinum was first recognized as a medical entity by Laennec, who reported it as a consequence of trauma in 1819.
Crepitus is often loud enough to be heard by the human ear, although a stethoscope may be needed to detect instances caused by respiratory diseases. In times of poor surgical practice, post-surgical complications involved anaerobic infection by Clostridium perfringens strains , which can cause gas gangrene in tissues , also giving rise to crepitus.
In most cases breast cancers are asymptomatic and are detected by routine clinical screening exams. In about 30% of cases a breast mass may be felt. [13] [14] The mass will not fluctuate with the menstrual period. [15] Changes to the overlying skin including dimpling, pinching, orange peel-like texture, or nipple retraction may be seen. [16]
The periareolar glands of Montgomery in the breast are also called Montgomery tubercles or Morgagni tubercles. These periareolar glands are small, papular tissue projections at the edge of the areola (nipple).Obstruction of the Montgomery tubercles may result in an acute inflammation, a clear or light brownish fluid may drain out of the areola (nipple discharge), and an subareolar mass may ...
