Abstract: We study entire positive solutions to the partial differential equation in $ \mathbb{R}^{n}$,

$\displaystyle \Delta_{x}u + (\alpha + 1)^2 \vert x\vert^{2\alpha} \Delta_{y}u = - \vert x\vert^{2\alpha} u^{\frac{n+2}{n-2}}, $

where $ x\in\mathbb{R}^2$, $ y\in\mathbb{R}^{n-2}$, $ n\geq 3$ and $ \alpha > 0$. We classify positive solutions with second order derivatives satisfying a suitable growth near the set $ x=0$.
