C4A.71
Merkel cell carcinoma of right lower limb, including hip
Clinical Classification Guidelines
Medical Intelligence & Overview
Merkel cell carcinoma (MCC) is a rare but aggressive type of skin cancer that originates from neuroendocrine cells in the skin. When diagnosed as C4A.71, it specifically refers to MCC located on the right lower limb, including the hip area. This cancer tends to grow quickly and can spread to other parts of the body if not treated promptly. Early detection and treatment are essential in managing this disease effectively.
Causes & Symptoms
Clinical Causes: Prolonged exposure to ultraviolet (UV) rays from sunlight or tanning beds Weakened immune system, such as from organ transplants, cancer, or immunosuppressive medications Extended history of skin injuries or radiation therapy in the affected area Older age, as MCC primarily affects adults over 50 Fair skin that burns easily and has less pigmentation
Key Symptoms: A rapidly growing, firm, flesh-colored or bluish lump on the skin A shiny, painless nodule that may be mistaken for a benign mole or cyst Ulceration or bleeding in the lesion over time Sometimes the lesion may be tender or itchy, but often it is asymptomatic
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a physical examination followed by a skin biopsy, where a small tissue sample is taken and examined under a microscope. Additional tests such as imaging scans (CT, MRI, PET scans) may be used to determine if the cancer has spread beyond the skin. Accurate staging helps guide treatment options.
Treatment Protocols: Treatment options often include surgical removal of the tumor with a margin of healthy tissue, sometimes combined with sentinel lymph node biopsy to check for spread. Depending on the stage and location, radiation therapy may be employed to target residual cancer cells. In some cases, immunotherapy drugs are used to boost the body's immune response against the cancer. Early intervention improves prognosis substantially.
