Malignant pilomatricoma

Malignant pilomatricoma is a rare type of skin cancer that originates from the hair follicle. It is also known as pilomatrix carcinoma and is a malignant form of pilomatricoma, a benign skin tumor.

Symptoms

The symptoms of malignant pilomatricoma can vary, but often include a rapidly growing, painful skin nodule that may ulcerate. The tumor is usually solitary and can occur anywhere on the body, but is most commonly found on the head and neck.

Causes

The exact cause of malignant pilomatricoma is unknown, but it is thought to arise from the transformation of a benign pilomatricoma into a malignant tumor. This transformation may be triggered by genetic mutations, radiation therapy, or other unknown factors.

Diagnosis

Diagnosis of malignant pilomatricoma is typically made through a biopsy of the tumor. The biopsy sample is examined under a microscope by a pathologist, who looks for characteristic features of the tumor. These features include abnormal growth of the hair follicle cells and the presence of calcification within the tumor.

Treatment

Treatment for malignant pilomatricoma usually involves surgical removal of the tumor. In some cases, radiation therapy or chemotherapy may also be used, particularly if the tumor has spread to other parts of the body.

Prognosis

The prognosis for individuals with malignant pilomatricoma can vary depending on the size and location of the tumor, as well as the individual's overall health. However, with early detection and treatment, the prognosis can be quite good.
