An interesting case of small vessel pathology following coronavirus infection

Vasculitis is a descriptive term for a wide variety of conditions characterised by inflammation of the blood vessels that may occur as a primary process or secondary to an underlying disease. Occlusive vasculopathy is a different clinical entity characterised by skin changes and ulceration of the lower extremities because of thrombosis of the small vessels of the dermis and is usually associated with pre-thrombotic conditions. Both conditions can be confirmed or excluded by skin biopsy. We report the case of a 63-year-old woman presenting with upper and lower respiratory tract symptoms followed by a vasculitic rash on both legs. The patient underwent extensive radiological and laboratory investigations that were negative apart from positive coronavirus OC43. A biopsy of the skin was performed. Considering the clinical presentation and the investigations performed, the diagnosis of small vessel vasculopathy following coronavirus OC43 has been suggested by the authors.
