The basal cell carcinoma (BCC) is a type of white skin cancer and also known as basal cell Skin cancer. Bcc is most common form of skin cancer. It develops from the so-called basal cells at the base of the epidermis. Initially formed a nodule or induration in to the affected area of skin . It tends to occur in areas which are exposed to a stronger sunlight. Accordingly, in 80% of cases basal cell carcinoma found at the head and neck. Rarely tumor growth is induced by arsenic or long-term use of medication which suppress the immune system. The average...

Actinic Keratosis Or Solar Keratosis The actinic keratosis is a specific lesion that produced by ultraviolet rays ( actinic means caused by radiation and keratosis means growth of keration on mucus membrane or on skin ). Since ultraviolet light occurs naturally in sunlight, actinic keratosis is also known as solar keratosis . The actinic keratosis is a skin condition that can develop into squamous cell carcinoma (squamous). Dermatologists also consider actinic keratosis as in-situ carcinoma. Actinic keratosis is understood as an early form of skin cancer that can remain inconspicuous for long years. However, there is also the possibility that...

Colorectal cancer is also known as Bowel cancer or colon cancer or rectum cancer. Colorectal cancer can generally arise in any part of the intestine: in the small intestine, in the colon or in the anal area. Tumors in the small intestine or in the anal area come much rarer than tumors in the colon, they are also treated differently. Malignant tumors mainly develop from cells of the intestinal mucosa. Depending on which portion of the colon is affected by cancer, doctors distinguish between Rectal cancer and Colon cancer. When the tumor is located in the last section of the...

This is a rare benign tumor, most often occurring in children under 12 years. It represents less than 1% of all brain tumors. In children, the most frequent site of this tumor in the lateral ventricles. Plexuspapillome grow slowly inside the ventricles. They  may block the flow of cerebrospinal fluid. This can cause hydrocephalus and increased the intracranial pressure. Papillomas of the choroid plexus are usually congenital neuroectodermal tumors, they make up about 1% of all tumors of the CNS. Most often they are sitting in the lateral ventricles, sometimes they are multiple, often sit in the 3rd ventricle or...

A oligodendroglioma is a bran tumor , which results from cells in the brain form the scaffold for nerve cells. The corresponding cells is called oligodendrocytes . However, the scaffold is not only occur from oligodendrocytes and other cell types (eg. Astrocytes). Overall, it refers to the supporting tissue as Glia . All tumors that arise from this tissue can therefore summarized under the umbrella of term gliomas. The name oligodendroglioma therefore derived from the cell name and the tumor group. Oligodendroglioma: Frequency Oligodendrogliomas represent about ten percent of all gliomas. They occur most likely in middle-aged (between 35 and 50...

A neuroma (Neuron = nerve cell) is a benign, slow-growing brain tumor that occurs mostly in the posterior fossa. The most commonly occur in the Schwann cells of the eighth cranial nerve. This nerve is a twin Cochleovestibular nerve, therefore has two components – the auditory nerve (cochlear nerve) and the balance nerve (vestibular nerve). The acoustic neuroma almost always grows from the vestibular portion of the 8th cranial nerve, resulting in the name often used vestibular schwannoma. Cranial nerves are made of very, very thin fibers that are encased by a sheath of connective tissue. This case is made...
