Is there a link between cellulitis and surerficial thrombophleditis?

Not really: Cellulitis is a soft tissue infection of the skin and subcutaneous tissues. Superficial thrombophlebitis is blood clots in the small superficial veins under the skin. These blood clots can become infected causing suppurative thrombophlebitis and can have surrounding cellulitis.

Not usually: In fact, superficial thrombophlebitis is often mistaken for cellulitis (and vice versa), but we work hard to distinguish the two because we treat them very differently.
