Rare neonatal malignant primary orbital tumors: Three case reports

Figure 1 A 1-mo-old male newborn. A: A mass located in the right eye, with proptosis; B and C: Axial T-1 weighted (B) and T-2 weighted (C) magnetic resonance images of the orbit revealed a large mass near the lateral orbital wall with slightly shorter T1 and shorter T2 signals. The eyeball structure is unclear, with abnormal signals; D: Gross morphology of the tumor showing the tumor tissue around the eyeball; E and F: Histopathologic analysis including micrographs after hematoxylin-eosin (E, × 20; F, × 40). A small, round, dark blue tumor with a monotonous, highly cellular pattern was observed with tumor cell atypia, and poorly differentiated cells.
