the parotid gland is the one salivary gland that encapsulates "late", and therefore can envelop adjacent lymph nodes. Thus, lesions within the parotid capsule proper can be either parotid or lymphatic origin, thus a "parotid mass" isn't necessarily of parotid origin. An enlarged lymph node is usually just a manifestation of your immune system reacting to something in the neighborhood (infection, inflammation, etc.). And if it is a parotid tumor, most are benign (when dealing with the salivary glands, the smaller glands tend to have more aggressive lesions, while the largest- the Parotid- tends to have benign tumors.

Depuytren contracture is a hypertophic scarring of and around the flexor tendons in the palm of the hand.

Ultrasound guided injection of collagenase (an enzyme) can dissolve some of the scarring. An oral herb cocktail that can be obtained from Natalia Bragg in Maine will help to heal the lesions and to prevent them from recurring (Knot II Bragg farms)
