  • Treatment for Morton's Neuroma - San Francisco Podiatrist Union Square CA What is Morton's Neuroma - San Francisco Podiatrist Union Square CA Dr. Bill Metaxas discusses the symptoms, causes and treatments for Morton's Neuroma. MORTON'S NEUROMA The term "neuroma" means a "tumor of a nerve". It is an abnormal growth of cells within a nerve, and the majority of them are benign, but a few rare tumors are cancerous. These true neuroma's generally occur in the larger nerve trunks of the ankle and lower leg, and in other parts of the human body. They can occur in the smaller nerves of the foot, but this is very uncommon. Over 100 years ago, a British physician named a benign tumor of the foot after himself and called it "Morton's neuroma". Modern medicine has shown that this tumor, which most often occurs between the bases of the 3rd and 4th toes, should be more accurately termed "perineural fibrosis" because it is a build up of scar tissue (fibrosis) around, not within, the small nerves between the metatarsal heads. This scar tissue becomes enlarged and causes compression on the nerve, which results in decreased blood and oxygen to the affected nerve segment, resulting in pain. This neoplasm or tumor can occur between any of the metatarsal heads of the foot. Causes Morton's neuroma, or perineural fibrosis, is caused by local irritation of a segment of a nerve in the front part of the foot which rubs up against a thick ligament beneath the metatarsal heads. There is an initial inflammatory reaction resulting in scarring or ...
  • Squamous Cell Carcinoma Treatment In this tutorial, Chris Schach MD, discusses diagnosis, etiology, and treatment of squamous cell carcinoma. Watch Tutorials given by US Board Certified dermatologists at . Key Points *Common skin cancer, forming in the cells of the outer skin layer *Most cases caused by sun exposure, but may be the result of other factors *Consists of scaly, crusted lesions which are tender and slow-growing and may ulcerate Squamous cell carcinoma (SCC) is a common skin cancer, which forms in the squamous cells, which make up the outer layer of skin. The condition typically presents in areas exposed to sun, such as the face, lips, ears hands, arms, and lower legs, though it may develop in other areas. It sometimes develops on mucosal surfaces such as the genitals or mouth. SCC in situ is confined to the epidermis, the outer skin layer. SCCs which are invasive spread to deeper skin layers. The condition typically presents as a scaly, crusted lump or bump, which is tender and slow growing. The lesion may develop sores and ulcerate. Lesions may be any size, from very small, to centimeters in diameter. In a small percentage of cases, SCCs may metastasize, most often when located on the lip, ear, back of hand, or scalp. SCC is most often caused by an accumulation of sun exposure. Other factors which may increase the likelihood of developing the condition include family history, smoking, burns, persistent ulcers, long-term use of immunosuppressants ...

  • Neck/Arm Pain: Foraminal Stenosis with Radiculopathy Patient Maxie was on duty in his patrol car when he was rear ended. At the time he did not experience any pain related to his accident. 5 years later Maxie began to experience neck pain running down his shoulder and into his right arm. Maxie said, its like someone put your shoulder in a vise and clamped down so hard that the pain would radiate into your neck and you could feel it in your eye socket. Maxie tried acupuncture and massage therapy which seemed to temporarily relieved the pain but it always returned. To Maxie, the pain was just an irritating part of life that he had to put up with and built up a tolerance for. But the pain slowly got worse and Maxie went back into his medical care group and they scheduled Maxie for X-rays to be taken in 4 months. Maxie continued working and while patrolling on his motor bike he hit an oil slick and lost control of his motorcycle, laying it down on the road. When he attempted to right his motorcycle, Maxie aggravated his older injury. When he was taken for treatment, the Doctor noticed a muscle in his neck and shoulder twitching. The Doctor sent Maxie in for an MRI. The MRI showed a severe bone spur at level C4-5 and C5-6. Maxie was given the option of having a cortisone shot or surgery. Maxie opted for surgery as the cortisone shot was not going to fix the problem. He was referred to Dr. Hamada who confirmed that Maxie had severe foraminal stenosis with radiculopathy. Dr. Hamada gave Maxie two options, one being bone fusion the other a ...

  • Ball of Foot Pain - Podiatrist in North TX MORTON'S NEUROMA Im not even sure who Morton was, but he must have a heck of a pain in the ball of his foot! Mortons neuroma is actually perineural fibrosis. In English, this is chronic scarring around a nerve. This scarring is almost an onion skin formation of scar tissue layered with fluid around a small interdigital nerve. The more fluid, the more scar, the more pain you experience. This is a compression problem. The nerve is compressed with scar and the ligament that connects the metatarsal (the long bones connected to your toes). Permanent nerve damage can occur in neuromas. What causes neuromas? Anything that compresses your toes together can cause a neuroma. Commonly, it is a combination of faulty biomechanics coupled with improper shoe gear or repetitive stress activities that lead to neuromas. People with other foot deformities such as bunions and hammertoes are ay higher risk for neuromas. Injuries such as stress fractures and sprains can also cause neuromas. Whatever the underlying cause, neuromas usually progress from a minor irritation to a big pain in the foot! Symptoms of neuromas usually start with an annoying bunched up sock feeling in the ball of your foot. Taking off your shoes can alleviate these early symptoms, but somewhere along the way; the pain stays. It progresses to numbness, burning and pain in the ball of the foot which radiates to your toes. Electric shock treatment probably feels a lot like an interdigital neuroma. This can occur in between ...
  • Esophagus Cancer (adenocarcinoma)-Mayo Clinic Over time, Gastroesophageal Reflux Disease, or GERD, can lead to Barretts esophagus, dysplasia or even esophagus cancer (adenocarcinoma.) This video shows how cancer may gradually invade the esophagus, other organs and lymph nodes, progressing from early-stage disease to locally advanced disease to late-stage disease. It also discusses tests to locate cancer in the body, including a CT scan, PET scan, PET/CT scan and endoscopic ultrasound, and methods of treating cancer. Mayo Clinic has a very large team with an international reputation for its skill in diagnosing and treating reflux, Barretts esophagus and esophagus cancer.

  • Skin Cancer Squamous Cell Carcinoma Appearance Dr. Shane Chapman, MD discusses Skin Cancer Squamous Cell Carcinoma Appearance. See more at PLEASE RATE AND COMMENT!!! SCCs arising from actinic keratoses may have a thick, adherent scale. The tumor is soft and freely movable and may have a red, inflamed base. These lesions are most frequently observed on the bald scalp, forehead and backs of the hands. Cutaneous horns may begin as actinic keratoses and degenerate into SCC. SCCs originating on the lip or from apparently normal skin are aggressive and metastasize to the regional lymph nodes and beyond. Those SCCs beginning in actinically damaged skin, but not from actinic keratoses, appear as firm, movable, elevated masses with a sharply defined border and little surface scale. The potential for SCCs to metastasize is related to the size, location, degree of differentiation, histologic evidence of perineural involvement, immunologic status and depth of invasion. SCCs that arise in actinically damaged skin were previously thought to have a minimal potential for metastasis; however, such lesions may be aggressive. SCC first metastasizes to regional lymph nodes in the majority of cases.
