Benign neoplastic cells resemble normal cells without exhibiting significant cytologic atypia, while malignant cells exhibit overt signs such as dysplastic features, atypical mitotic figures, necrosis, nuclear pleomorphism, and anaplasia. Representative examples of benign neoplasms include papillomas, cystadenomas, and lipomas; malignant neoplasms include carcinomas, sarcomas, lymphomas, and leukemias. An abnormal and excessive growth of tissue which is uncoordinated with that of surrounding tissue and persists growing abnormally even if its original trigger is removed. Neoplasms usually, but not always, form masses, which are called tumors. The condition of having a neoplasm is called neoplasia. neoplasm NOS neoplasm and/or hamartoma neoplasms neoplastic
