Rare disease
Atypical tumour-like involvement of the colon in Henoch-Schönlein purpura successfully treated with the administration of factor XIII


Henoch-Schönlein purpura (HSP) is a type of systemic vasculitis of the small vessels, which frequently involves the skin, kidney and gastrointestinal tract. While the typical intestinal features of HSP include diffuse mucosal redness, small ring-like petechiae and haemorrhagic erosions, tumour-like lesions are rarely observed. The current study presents a rare case of HSP with an intestinal tumour-like lesion in the caecum. The intestinal lesion caused fresh melaena, and was completely resolved with the administration of factor XIII as described in previously reported cases. It is important to immediately undergo proper treatment for improving tumour-like lesions which may cause severe complications, such as excessive haemorrhage and stricture.
