Features of the course of acute nodal erythema
Acute erythema is a form of deep allergic vasculitis, developing with many infectious diseases (alarg, scarletin, brucellosis, pulmonary tuberculosis, etc.), as well as in the intolerance to a number of drugs (iodine, bromine, vaccine, etc.).
Frames from a few days to week: Increased body temperature,
Weakness, pain in the joints and muscles. Total disease duration
averages 3-4 weeks.
Their boundaries are defined in funeral, which depends on the edema of the surrounding tissues. Soreness has a different degree of severity, sometimes it is extremely intense, both when pressing and spontaneously. Localled knots in deep departments of the dermis and in subcutaneous tissue. Leather over nodes first bright pink, then she takes a stagnant blue color.
Quickly reaching a certain value, the nodes are further not incremented in size and, although sometimes there are focus, do not show inconsistencies to the merger. The number of nodes is different - up to 8-10, less often - more.
3-5 days after the occurrence of the nodes begin to be resolved, which manifests them with a seal, they become not so painful. Characteristically changing the color of the skin over the nodes: it becomes browned from the blue and red, then yellow-green.
The most important clinical sign is the full resolution of the nodes, without decay, which is usually observed after 2-3 weeks. In some cases, temporary pigmentation and peeling remain on the places of previously.
Nodes usually arise in the region of the protruding surface of the shins, as a rule, symmetrically. Less often they develop on the hips, on the extensitive surface of the forearm. A rare localization of rashes is face (on the edge of the age).
Chronic and migrating forms of noded erythema
Chronic nodular erythema is distinguished by a recurrent flow; Characterized by a small number of existing nodes that are not subjected to decay.
As for the migratory form of nodal erythema, the peculiarity of this type of disease is a subacute course and inclination to relapses. The nodes that arise in these cases are usually numerous, low-sensitive to pressure, differ in inclination to peripheral growth.
In most cases, this peculiar nature of the development of nodes has been detected from the very beginning of the disease, less often there is a seizure of nodular erythema on the usual type and only consistently detects the trend of individual nodes to migration. Skin rashes are localized on the legs, footsteps, often asymmetrically.
The disease is observed in women aged 30-40 years and may be accompanied by an increase in body temperature.
