Etiology. Pathogen – radiant fungus – an actinomycete, causing the formation of infectious granulomas from infected tissues to them, in purulent foci, it forms a Druze. Epidemiology. Infection occurs primarily practitioners, infectious diseases are the most important the following clinical forms: a) the actinomycosis of the head, neck and tongue, and b) actinomycosis of the skin. Generalized actinomycosis occurs rarely, associated with the pathogenesis Later in the angle of the mandible formed a dense infiltrate little off from the surrounding tissue is not altered. Above the infiltration of the skin is hyperemic, and in some areas gets purple-bluish hue. Patchy infiltration of the skin becomes thinner, in the subcutaneous tissue formed foci of softening, there are abscess, fistula formation have been opened and scanty discharge.

Abscess includes thick, viscous pus, which can detect drusen radiant fungus perifocal homes to soften the skin is hardening, formed tight folds valikoobraznye, which laid the fistulous passages. Often the disease is quite severe due to the accession of a secondary infection. Further details can be found at Somatic Experiencing, an internet resource. Actinomycosis of the skin occurs mainly in the form of gummy-knotted. The skin lesion is due to the fact that actinomycotic process extends to it from the underlying tissues. In this form of actinomycosis is formed a node with semispherical (or at least – a flattened) shape, this node can reach the size of chicken eggs. Node tight, painful, tight-knit with the underlying tissues, and therefore immobile, by palpation is not shifted.

Discoloration of the skin over the site is very slow, it gets first red, then – purple-violet color. In the area of the site for are pockets of softening, there are wormholes through which stands out thick pus. On examination, isolated from a fistula can be seen in pus yellowish grains – Druze radiant fungus. Reparative processes are characterized by the formation of crusts on the site of some fistulas undergoing further scarring. Along with this, the site of the formation of new foci of softening, and there New fistulas with purulent discharge. The disease is very torpid. Diagnosis. In typical cases, the diagnosis of actinomycosis of the skin, head and neck is quite simple, that can detect the disease even without resorting to differential diagnosis. For laboratory tests taken from the pus revealed the focus of softening, the Druze, selected from the pus was inoculated on Petri dishes with a special nutrient medium. Confirmation of clinical diagnosis may also serve as a positive skin test or with aktinolizatom statement with the same complement-fixation tests with a specially prepared antigen. Treatment: It is used intramuscular injection of penicillin in combination with scheme). Some patients have to resort to surgery. – Handbook of human disease
