Superficial ulcerating rheumatoid necrobiosis: a perforating rheumatoid nodule. 1985

J W Patterson, and P T Demos

We report a case of superficial ulcerating rheumatoid necrobiosis (SURN), which is a recently described cutaneous manifestation of severe rheumatoid arthritis. As with classic rheumatoid nodule, there is evidence that this lesion may result from a vasculitis. SURN appears to represent a form of "perforating" rheumatoid nodule, and completes a triad of major necrobiotic processes (granuloma annulare, necrobiosis lipoidica, rheumatoid nodule) that have been reported to show epidermal perforation.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009335	Necrobiosis Lipoidica	A degenerative disease of the dermal connective tissue characterized by the development of erythematous papules or nodules in the pretibial area. The papules form plaques covered with telangiectatic vessels. More than half of the affected patients have diabetes.	Necrobiosis Lipoidica Diabeticorum,Diabeticorum, Necrobiosis Lipoidica
D005260	Female		Females
D006099	Granuloma	A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents.	Granulomas
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis
D012215	Rheumatic Nodule	A small round or oval, mostly subcutaneous nodule made up chiefly of a mass of Aschoff bodies and seen in cases of rheumatic fever. It is differentiated from the RHEUMATOID NODULE which appears in rheumatoid arthritis, most frequently over bony prominences.

D012218	Rheumatoid Nodule	Subcutaneous nodules seen in 20-30% of rheumatoid arthritis patients. They may arise anywhere on the body, but are most frequently found over the bony prominences. The nodules are characterized histologically by dense areas of fibrinoid necrosis with basophilic streaks and granules, surrounded by a palisade of cells, mainly fibroblasts and histiocytes.
