(Basal Cell Carcinoma; Squamous Cell Carcinoma)
Skin Cancer – Definition
Skin cancer is a disease in which cancer cells grow in the skin.
The two most common kinds of skin cancer are:
- Basal cell carcinoma (a slow-growing cancer that begins in the inner part of the outer layer of the skin; rarely spreads to other parts of the body) — It accounts for more than 90% of all skin cancers in the United States.
- Squamous cell carcinoma (a cancer that starts in the outer layer of the skin) — It rarely spreads, but does so more often than basal cell carcinoma.
Toxic Shock Syndrome – Definition
Toxic shock syndrome (TSS) refers to a combination of symptoms that results from toxins produced by an infection with either Staphylococcus aureus or group A Streptococcus pyogenes bacteria. The disease can progress rapidly, causing failure of multiple body systems. Toxic shock syndrome can be fatal. There are two types of the disease:
- Menstrual type (associated with menstruation and tampon use) — The number of tampon-associated cases has decreased since the 1980s. Women have become more aware of the danger and modified their use of tampons. In addition, a highly absorbent type of tampon was removed from the market. Doctors are not sure what role tampons play in the disease. Absorbent tampons may cause dryness and breaks in the lining of the vagina.
- Nonmenstrual type (sometimes associated with a wound) — It can occur in men, women, and children.

Soft Tissue Sarcoma – Definition
Soft tissue sarcoma is a disease in which cancer cells are found in soft tissue in the body. Soft tissue includes muscles, tendons, connective tissue, fat, blood vessels, nerves, and synovial (joint) tissue.
There are many types of soft tissue sarcoma, including: alveolar soft part sarcoma, angiosarcoma, dermatofibrosarcoma protuberans, desmoid sarcoma, fibrosarcoma, leiomyosarcoma, liposarcoma, malignant fibrous histiocytoma, lymphoma (lymphosarcoma), malignant peripheral nerve sheath tumor, rhabdomyosarcoma, and synovial sarcoma. Treatment will differ depending on the type of cancer and the location and size of the tumor.
(Primary Sjogren’s Syndrome; Secondary Sjogren’s Syndrome)
Sjogren’s Syndrome – Definition
Sjogren’s syndrome is an inflammatory disease. The immune system destroys cells in exocrine glands. It occurs most often the tear and salivary glands. It is a lifelong condition. There are two types:
- Primary Sjogren’s syndrome — occurs alone
- Secondary Sjogren’s syndrome — occurs with other rheumatic conditions such as rheumatoid arthritis, scleroderma, or systemic lupus erythematosus (lupus)
