Figure 3 Histopathology of angioleiomyoma. A: Ileal tissue with a well-circumscribed subserosal tumor; B: Proliferative spindle smooth muscle cells bearing brightly eosinophilic cytoplasm and arranged in fascicles, punctuated by variable-sized vascular channels. The vessels were irregularly dilated with attenuated walls; C: The proliferative smooth muscle cells were highlighted by desmin immunostaining, while the cavernous vascular channels lacked a well-formed muscular wall.
