Squamous morphology in endometrial tumours: two challenging cases including a rare pilomatrix-like variant

Key Points

• To present two challenging cases of endometrial carcinoma with squamous differentiation and compare their features.
• Two cases of endometrial carcinoma with squamous differentiation are reported.
• Features are compared using clinicopathologic and immunohistochemical characteristics.
• Both cases exhibited predominant squamous differentiation in endometrial carcinoma.
• Findings suggest that the variants are challenging to diagnose and recognize.
