Sheets and large masses of tumor cells grow in disorganized fashion. The cells grow slowly by a process known as mitosis, adhere (stick) to each other and spread out in a layer formation to collectively form a tissue. Gross and microscopic features of malignant granular cell tumors Histopathologic features of malignancy are unmistakable in some patients and do not pose any diagnostic difficulty. Furthermore, if the differentiation is based on the histologic features, more particularly the increased capacity of the tumor cells for proliferation, some tumors—for example, basal cell epithelioma—while displaying all the microscopic characteristics of malignancy are relatively benign in their clinical behavior.
