Presentation Transcript

  1. Congenital capillary hemangioma at birth at 2 years of age after the lesion had undergone spontaneous regression

  2. Sacrococcygealteratomas

  3. Neuroblastoma • Neuroblastoma is composed of small cells embedded in a finely fibrillar matrix (neuropil). with Homer-Wright pseudo-rosette. • Ganglioneuromas, arising from spontaneous or therapy-induced maturation of neuroblastomas, are characterized by clusters of large cells with vesicular nuclei and abundant eosinophilic cytoplasm (arrow), representing neoplastic ganglion cells. Spindle-shaped Schwann cells are present in the background stroma.

  4. Retinoblastoma cohesive tumor in retina abutting optic n High power view showing Flexner-Wintersteiner rosettes (arrows) and numerous mitotic figures.
