What is Malignant Cylindroma?
Malignant Cylindroma also called Spiradenocarcinoma, is a very rare type of skin cancer that starts from the sweat glands. In most cases, this cancer develops from a non-cancerous (benign) lump called a spiradenoma or cylindroma, which has been present on the skin for many years without causing problems.
But in some people, usually in older adults, this harmless lump can slowly change and turn into a cancerous tumour.
Symptoms
This cancer often appears on the scalp, face, or neck, but it can also appear on the arms, chest, or other areas. People usually notice a bump that has been there for a long time.
Over time, it may start growing faster, become painful, change color, or start to bleed. Sometimes, the skin over the lump breaks open and forms a wound that doesn’t heal. These are warning signs that the lump may have become cancerous.
Diagnosis
Diagnosis is confirmed by taking a small sample of the lump through a biopsy. This tissue is then looked at under a microscope to check for cancer cells. If cancer is found, further scans like MRI or CT may be done to check if it has spread to other areas of the body, especially the lymph nodes.
Treatment
Treatment usually involves surgery to remove the entire lump along with some healthy skin around it. This is done to make sure all the cancer is taken out. If the cancer is large, deep, or has spread, doctors may also recommend radiation therapy or chemotherapy. Since this cancer is rare, treatment plans are made based on the size, location, and behavior of the tumour.
Prognosis
The outcome depends on how early the cancer is caught and treated. If it is found early and completely removed, the chances of recovery are much better. But if it spreads to other parts of the body or comes back after treatment, it can be more serious. That’s why regular follow-up visits with a doctor are important, even after successful treatment.
Although it is rare, this cancer can be dangerous if ignored. Paying attention to any old skin lumps that suddenly start changing can help detect the cancer early.
