.box {
    &-title {
        ...
    }
}

...
// hoge ページ
.hoge {
    .box {
        @include box-base;
    }
}

// fuga ページ
.fuga {
    .box {
        ...
    }
}

_box.scss
@mixin box-base {
    $target: unquote("#{&}");

    @if str-index($target, ' ') == null {
    } @else {
        $target: str-slice($target, str-index($root, ' ') + 1, str-length($target));
    }

    &-title {
        ...
    }

    // ここで `.box-title` を取りたい
    @each $category in $categories {
        &.#{$category} {
            #{$target}-title {
                background-image: url(#{$category}_title_bg.gif);
            }
        }
    }
}

とりあえずネストは1つしか考慮してない。
