DefinitionThis section has been translated automatically.
Very rare vasculitic clinical picture occurring in association with diseases in which circulating immune complexes play a pathogenetic role. Clinically, symmetrical, red, usually asymptomatic erythema, papules or plaques are predominantly localized on the lateral trunk, also in a linear orientation (rope signs or "rope signals"). There are clinical similarities to urticarial vasculitis.

EtiopathogenesisThis section has been translated automatically.
The pathogenesis of the disease is not yet clear. Some authors assign it to the spectrum of interstitial granuloma anulare (Rose C 2017). Other authors consider it to be a late stage of vasculitis.
LocalizationThis section has been translated automatically.
Clinical featuresThis section has been translated automatically.
Eminently chronic, bilateral, symmetrical, up to about 3.0-20 cm long and 0.5-1.0 cm wide, coarse, painless, band-like erythema, also reddish papules and plaques (also rope signals) in the posterior or anterior axillary line, the chest, the buttocks are described as characteristic. These may also spread to the adjacent extremities.
Anular patterns are also found(erythema anulare-like).
Not infrequently, the changes occur together with rheumatoid arthritis.
HistologyThis section has been translated automatically.
Dense, band-shaped histiocytic infiltrate in the middle reticular dermis. Furthermore, there are "flame figure" type (but not to be confused with these), so-called "floating signs", mostly basophilic areas consisting of degenerated collagen. These are surrounded by rosette-like arranged, partly also pleomorphic histiocytes (some mitoses can also be detected). Furthermore, there are discrete perivascular lymphocytic infiltrates and some neutrophil and eosinophilic leukocytes.
|Accentuates around post-capillary venules and larger vessels in the skin and subcutis|
|Capillaries omitted or less strongly involved|
|Damage to endothelial cells|
|Fibrin in/around vessel walls|
|Perivascular extravasation of erythrocytes|
|No/mild edema in the papillary dermis|
|Collagen degeneration with slight basophilic necrotic lesions of variable extent, surrounded by palisade granulomas|
|No significant number of eosinophils|
|No plasma cells or fibrosclerosis|
Differential diagnosisThis section has been translated automatically.
Lyme disease: Cutaneous Lyme disease(possibly with an interstitial granulomatous dermatitis). Clinical-serological clarification!
Lyme disease: Rare manifestation of cutaneous Lyme diseasewith interstitial granulomatous dermatitis. In this case there are mostly plasmacellular accompanying components. Clinical clarification!
Morphea: The early stage of morpheamay (although less frequently) have a histiocytic component which gives way to dermatosclerosis in a later stage.

Treatment of the underlying disease. Good success was achieved in individual cases with Infliximab.
Note(s)This section has been translated automatically.
Interstitial granulomatous dermatitis is a rare disease whose entity is still controversial. The histological changes are unspecific. It is probably a reaction pattern that occurs in the context of different diseases, such as systemic vasculitides, collagenoses, rheumatoid arthritis, lymphoproliferative diseases, subacute bacterial endocarditis and chronic active hepatitis. These diseases have in common the presence of circulating immune complexes.
In 1951, Churg and Strauss described analogous changes in 13 patients with vasculitis as "allergic granulomas" in the skin ("Churg-Strauss granulomas").
Case report(s)This section has been translated automatically.
- 59-year-old patient who had been observing the appearance of skin-colored to reddish, partially ulcerated papules on both elbows for several years. One sister was diagnosed with chronic polyarthritis.
- For about 3 months additional appearance of reddish, painless strands on the lateral trunk as well as in the area of the posterior axillary line and the proximal upper arms. In the meantime, these strands blistered off and left striped hyperpigmentation. In addition, the patient had been complaining for years about intermittent joint pain in the finger, foot and knee joints.
- Clinic: Up to 2.0 cm large, flat, partly skin-coloured, partly reddish, firm, partly ulcerated and encrusted, partly confluent papules on the elbows; about 30 cm long and 0.6 cm wide, reddish, coarse, painless plaque in the posterior axillary line with overlapping on the proximal upper arm. In the area of the left posterior axillary line a slightly shorter and less prominent similar strand appeared.
- Laboratory findings: LDH: 320 U/l (normal range:120-240 U/l), CRP: 7.5 mg/dl (normal range:< 0.5 mg/dl), iron: 10 mmol/l (normal range:14-32). Sm-AK: positive; nRNP-Ak: positive. Other routine laboratory parameters such as rheumatoid factor, ANA, ds-DNA-AK, SSA, SSB, borrelia serology showed no pathological findings.
