Sarcomas are a varied and a very rare group of malignant tumors made of cartilage, muscle, vascular or hematopoietic tissues and hence sarcoma is a cancer that results from transformed cells of mesnchymal origin. These are different from tumor that originates from epithelial cells which are known as carcinoma.
Sarcomas are classified according to the type of tissues that they resemble but majorly they are of two types: bone and soft tissue.
Soft tissue sarcomas mostly form in fat, cartilage, muscle, blood vessels and other supportive tissues of the body with liposarcomas, rhabdomyosarcomas and osteosarcomas forming in fat, muscle and bone tissues respectively.
Apart from being named in respect to the tissues they originate from, sarcomas are further graded as either low, intermediate or high on the basis and frequency of certain cellular and sub cellular characteristics associated with malignant biological behavior.
Types of Sarcoma
There are several types of sarcoma cancer and they include the following:
Sarcoma botryoides is the type of sarcoma that is usually found along the walls of structures that are lined with mucus for example the bile ducts or urinary ducts of infants or the vaginal walls of females below 8 years.
Chondrosarcoma is a cancer made of cells originating from transformed cells that form cartilage. Almost 30% of skeletal system cancers are chondrosarcoma and can present at any age.
An osteosarcoma is a cancerous tumor that forms in a bone and is most prevalent amongst young people.
An epithelioid sarcoma is a rare soft tissue tumor with an epitheliod pattern. It is common among young adults.
An angiosarcoma is a sarcoma that originates from malignant cancer of endothelial-type cells that line walls of the vessels (such as blood vessels).
Also known as phyllode tumors, cystosarcoma phyllodes are usually large masses that grow so fast and that form from the stromal cells of the breast.

Laser skin resurfacing is a wonderful innovation that can help with a variety of skin problems. Wrinkles, acne scars, sagging skin, and skin tone and texture are all conditions that laser skin resurfacing can help with! Depending on the specific problem, as well as the patient’s lifestyle and pain tolerance, there are a number of different lasers that can be used to help improve the skin.
Laser Skin Resurfacing: What is it?
Lasers used to treat various skin conditions vary in strength, ranging from gentle to aggressive. If a person is willing to spend a few days recovering, an aggressive treatment such as a CO2 laser can provide dramatic results after just one session. If the patient doesn’t have the time to spare for recovery, there are gentle lasers available that require no downtime, but may need multiple sessions for optimal results.
Dr. Melda Isaac at MI-Skin Dermatology Center is an expert dermatologist in Washington, DC who is known for her skill with laser skin resurfacing. She will always have a thorough consultation with her patients before deciding on an individual treatment plan to achieve realistic, optimal results. She takes into account her patients’ lifestyles, skin concerns, and desired results in order to formulate a comprehensive treatment and skin care plan.

Laser skin resurfacing can be combined with other treatments as well for the most comprehensive treatment possible. For example, Botox can be used to smooth and prevent wrinkles while laser skin resurfacing deals with acne scars and skin texture.
Neuromodulators, fillers, and even skin tightening treatments such as Ulthera can be used safely in conjunction with laser skin resurfacing in what’s called a “liquid facelift.” For patients who want effects similar to a surgical facelift but aren’t quite ready to go under the knife, or who simply don’t have the time needed to recover from surgery, liquid facelifts are the next best alternative!

Hair loss, otherwise known as alopecia, is an extremely common affliction that strikes both men and women, although men are more prone to the condition. Male pattern baldness is extremely common, and because it runs in families, there are no preventative measures to take to avoid its onset. However, there is a way to maintain a full head of hair even with genetically predetermined hair loss. Hair transplants are a safe and effective way to fight baldness and regain a full head of hair.
Hair transplant technology has come a long way through the years. Today, it is a much more effective procedure than it was ten or twenty years ago, and the results are much more natural looking. At Cosmetic Laser Dermatology, expert hair restoration in San Diego is done through NeoGraft, the most advanced means of hair transplantation available. NeoGraft is an innovative system that allows individual hair follicles to be transported in groups, allowing for quicker treatment and very natural looking results. In the past, unnaturally straight parts gave away that a person may have had a transplantation procedure, but nowadays, using the most sophisticated technology, hair restoration results are much more natural.
Hair loss isn’t limited to men; many women also start to lose their hair later in life. For women, hair loss can be extremely distressing. However, with hair transplants, women are also able to regain a fuller head of hair. NeoGraft hair transplants can be used on men and women of all ages, although it is recommended that younger candidates attempt other means of regaining hair such as Rogaine before committing to hair transplants. Generally, NeoGraft patients are at least in their mid-twenties. A full head of hair is within reach of all balding men and women!
March 18, 2015Comments Off on What are the Signs of Kidney Cancer?
Kidney tumors are one of the most common conditions treated by urologists, with an estimated 25,000 cases diagnosed per year. While any cancer diagnoses can be overwhelming and a source of fear and anxiety for most patients, kidney cancer patients usually have a very good prognosis when diagnosed early. Many tumors can be treated with surgery alone when caught early and before they’ve had a chance to become too large or metastasize to other organs.
There are two types of kidney cancers depending on where the malignant cells originate – either renal cell carcinoma (RCC) or transitional cell carcinoma (TCC.) Tumors can often be asymptomatic – meaning the patient does not experience any signs or symptoms that something is wrong or that a tumor is present. The most common symptoms include:
Blood in urine
Chronic abdominal pain
However, it is important to consider that all of the symptoms associated with kidney cancer can also stem from another source, and the presence of one or several does not necessarily indicate cancer. Patients experiencing unexplained symptoms that are persistent and do not resolve on their own over time should seek medical attention as soon as possible to obtain an accurate diagnosis.

Smoking can significantly increase the risk of developing kidney and other cancers, and factors such as genetics and other underlying health conditions like Hepatitis C infection can also increase the risk for developing tumors.
February 20, 2015Comments Off on Exercising After Knee Surgery
The thought of getting back to physical activity and a regular exercise routine after a surgical procedure might sound counter-intuitive, but a regulated exercise plan is necessary to ensure proper healing and recovery, and in many cases event to avoid re-injury.
Depending on the injury and patient, most surgical knee repairs are now performed with a procedure known as arthroscopy. Due to its minimally invasive approach, arthroscopy (also known as arthroscopic surgery) usually allows for less complications and a shorter recovery period. An orthopedic surgeon will make several small incisions around the joint and insert an arthroscope, which is a small surgical tool equipped with a camera and light at the end. The camera relays images over a video screen in the surgical room, allowing the surgeon to get a better look at the inside of the joint and to work with greater precision.
Once the surgery is complete, patients will begin working with a physical therapist immediately with light range of motion exercises to prevent stiffness and work up to strength training and stretching.

February 12, 2015Comments Off on 4 Ways Periodontists Can Fix Your Smile
Your smile is one of the first things that people notice about you, which is why it is easy to see why people would want a healthy looking smile. Periodontists specialize in working with gums as well as placing dental implants. They are experts at helping you achieve the healthy gums that will make your smile shine. Here are four smile improvement procedures that periodontists like Dr. Alexandre-Amir Aalam and Dr. Alina Krivitsky at the CENTER for Advanced Periodontal & Implant Therapy perform to help you gain confidence as well as increased function of your teeth and gums.
Periodontal disease, trauma, age, birth defects, and brushing too hard can all contribute to a receding gum line. Not only does this cause uneven gums that makes them appear unhealthy and unattractive, but it can also cause sensitivity when eating certain foods by exposing your teeth. This can be corrected with gum graft surgery. Gum graft surgery is usually done by removing some tissue from the roof of your mouth and attaching it to where the gums have receded. This will help reduce further gum recession, cover the exposed roots, reduce the risk of root sensitivity, and give your teeth a more attractive smile.

Dark spots and patches can appear on the gums when there are abnormally high amounts of melanin. Having dark discolored gums, when they should be a pale pink, can affect confidence and self-esteem. There are a few different ways this can be treated. periodontists use a state-of-the-art microdermabrasion technique to actually remove the pigmented area rather than using chemicals to cover it up.
Gummy Smile Correction
If your teeth look small and stubby, aesthetic crown lengthening might be an option to get rid of a gummy smile. Sometimes gummy smiles can be caused by genetics or gingivitis. Periodontists can then remove excess gum tissue to reshape the outline of the gums and expose more of your teeth for a more attractive smile.
Having a missing tooth not only looks unattractive, but it can also cause problems in your mouth. A dental implant can be used to permanently replace a missing tooth and is a better option than dentures. A dental implant is a titanium rod that is surgically placed into the jawbone and is then topped with a crown. This crown is natural in color and will look just like a natural tooth.
No matter what smile improvement procedure you need to make your smile more attractive, Dr. Aalam and Dr. Krivitsky are not only experts, but they also believe in helping their patients be comfortable and the procedures be painless.
