Basal Cell Carcinoma
Basal cell carcinoma is a skin cancer whose development is very favorable treatment.
Other skin cancers are squamous cell carcinoma and malignant melanoma.
This is the most common cancers (almost half the cases) in the United States and its incidence is increasing.
It particularly affects people with fair skin (blond or red) and is correlated with exposure to sunlight and ultraviolet radiation.
The clinical forms / appearance
Basal cell carcinoma may take many forms. The pathognomonic appearance (signs for sure diagnosis) is a translucent pearl.
* The plan scar carcinoma: the form of small translucent papule at the beginning and then spread gradually turns into a baking center whitish scar
* The basal cell carcinoma ulcer: shape digging the thickness of the skin (ulceration), with or without sharp edge, up to the underlying anatomical structures and damage them.
* The basal cell carcinoma nodular form of small nodules protruding, globose, waxy tinge.
* The basal cell carcinoma and budding vegetation: dark red, bleeding freely, was differentiated squamous cell carcinoma.
* The basal cell carcinoma Pagetoid: looks like a pink tablecloth covered with scales.
* The basal cell carcinoma erythematosus: a red form with beaded edges.
* The basal cell carcinoma or sclérodermiforme morpheaform comes in the form of a white plate.
* The Basal cell carcinoma Pigmented (tattoos) look very black to differentiate it from pigmented melanoma and seborrhoeic warts.
A pathological examination shows that the tumor cells are cells of the basal layer of the epidermis with abnormal proliferation and irregular.
Treatment consists mainly of a simple surgical excision with a safety margin around the edges of the visible lesion. Microscopic examination of the surgical specimen must show that the removal of the tumor is considered complete for the tumor is definitively treated, and removed the tumor does not grow back. If excision is incomplete, the tumor will grow back from some tumor cells still present within the skin.
They are only available in case of failure of surgical removal and their effectiveness is reduced with increased recurrence and cosmetic results below:
* Local radiotherapy;
* Phototherapy after pre-sensitization of the tumor Metvix (r) or Metvixia (r) by country
* Use of certain medications especially topical imiquimod in basal cell carcinoma superficial.
This is mainly to protect themselves from sun exposure, especially if you are a patient at risk (fair skin, blond or red).
