The histological examination made with hematoxylin and eosin [Figure 3a] and smooth muscle actin staining [Figure 3b] revealed the diagnosis of angioleiomyoma. The lesion was composed of large vascular channels of varying caliber, surrounded by thick walls of irregularly arranged, spindle-shaped cells [Figure 3a]. The spindle-shaped cells showed elongated blunt-ended nuclei and eosinophilic cytoplasm-forming smooth muscle bundles showing interlacing patterns with collagen fibers between dilated and slit-like vascular spaces [Figure 3b].
