The degree to which a spark plug disperses the heat it receives is called its heat range. Spark plugs with a high degree of heat dispersal are called high heat range (cold type) and those with a low degree of heat dispersal are called low heat range (hot type).
Invasive Mammary Carcinoma (IMC). Invasive mammary carcinoma, also known as infiltrating mammary carcinoma, is a mixture of invasive ductal and lobular carcinomas; meaning the cancer grows at the junction of the duct and the lobule.nvasive mammary carcinoma is treated with a lumpectomy or mastectomy, depending on the size and location of the tumor. Your oncology team also may recommend chemotherapy and/or radiation, hormonal therapy or biologic targeted therapy. Sometimes an MRI is done to help determine the diameter of the tumor.
Proliferating tricholemmal tumor (PTT), also known as proliferating pilar tumor or pilar tumor, is a well-circumscribed proliferation of squamous cells [18, 19]. It commonly occurs on the scalp or other parts of the head and neck as a gradually enlarging nodule or tumor (Figure 17).
