Skin Sarcoidosis Sarcoidosis Signs

Skin sarcoidosis and sarcoidosis signs

        Except for Lofgren erythema nodosum syndrome, they usually occur in the chronic form of the disease and in less than 10% of cases. Infiltrative, firm lesions, embedded in the dermis, are not inflammatory and are purplish red or brownish. Sarcoid small nodules are papules of a few millimeters. Large sarcoid nodules are larger than 1 or 2 cm. Outside the Lofgren syndrome and arthritis, acute or subacute sarcoidosis is rare.

Skin locations

        They are various and distinguished classical lesions specific that support granuloma. The specific skin lesions were observed in 15 to 35% of patients. They may arise during the course of the disease. They are most often chronic and indolent. One can observe red infiltrated lesions or sometimes brownish red, painless, not pruritic whose vitropression revealed yellowish grains. Their location is often in the face but can also sit anywhere in the body. Are highly polymorphic in their clinical presentation and esthetic impact.

        Lupus Pernio means purplish, indurated lesions, which appear mainly on the cheeks, nose, lips and ears. These lesions can be erosive. They are more common among older women and black subjects. Sarcoidosis nodules can appear on old scars, perfectly quiescent, which increase in volume and become erythematous.

        One can observe sarcoid lesions like small nodules on the face, on the members and less often on the trunk. They are infiltrated and variable in color. Sarcoidosis skin lesions are often diagnosed by biopsy of an atypical lesion. The non-specific skin lesions are mainly represented by nodosum erythema, which can integrate into the Lofgren syndrome and which it is unnecessary to biopsier. More rarely may be vasculitis erythema.
