Micrograph of a small cell carcinoma showing cells with nuclear moulding. FNA specimen. Field stain.

In histopathology, nuclear moulding, also nuclear molding, is conformity of adjacent cell nuclei to one another.

It is a feature of small cell carcinomas and particularly useful for differentiation of small cell and non-small cell carcinomas, i.e. adenocarcinoma and squamous carcinoma.
