You have a rash . It's red and itchy and you aren't sure whether to call your doctor or take a trip to the pharmacy for some over-the-counter cream. Skin rashes come in all shapes and sizes and while they can be common, they can also be scary. When you are suddenly covered with red bumps, blisters or a spreading pinkish, scaly or inflamed patches you wonder if it is the sign of something serious.

Definition Porphyrias are a group of rare disorders passed down through families, in which an important part of hemoglobin , called heme, is not made properly. Heme is also found in myoglobin, a protein found in certain muscles.

This causes abnormal amounts of porphyrins or related chemicals to build up in the body. There are many different forms of porphyria. The most common type is porphyria cutanea tarda (PCT). Drugs, infection, alcohol, and hormones such as estrogen may trigger attacks of certain types of porphyria.

Cutaneous T-cell lymphoma (CTCL), however, is a skin cancer that resembles a rash rather than a new abnormal growth. Cutaneous T-cell lymphoma is almost like having "leukemia of the skin" in that there is an abnormal proliferation of blood cells that usually fight off infection (in this case, an expansion of the T-cells). Although there are various types of CTCL, the most common is known as mycosis fungoides. The cause of this condition is not known, although in some regions of the world, it has been linked to a virus known as human t-cell leukemia virus-1. Unlike other skin cancers, this cancer is in no way caused by too much sun exposure. CTCL affects approximately 5 people per million per year with men being affected twice as often as women. The condition tends to be found in older people, with the averag...
