What pattern forms when a small endothelial cell is surrounded by larger neighbouring cells, giving a flower-like appearance?

• A. Pupil
• B. Semilunar Fold
• C. Retina
• D. Rosette

Answer: (D)

This question tests recognizing a rosette pattern in histology. A rosette is a radial, flower-like arrangement where a small central cell or lumen is surrounded by larger neighboring cells, producing petal-like extensions around the center. The term literally evokes a rose, and this distinct pattern helps identify certain tissues or tumors that exhibit this organized circular layering. In this scenario, the central small cell encircled by surrounding cells forms that characteristic flower-like appearance, which is exactly what defines a rosette. The other terms describe specific anatomical structures (pupil, semilunar fold, retina) rather than a pattern of cellular organization, so they don’t match the described arrangement.
