Besides a slight local oedema affecting the malleoli, scrotum, eyelids, etc., or accompanying the cutaneous eruptions just mentioned, a more decided infiltration of the subcutaneous cellular tissue occasionally exists in the vicinity of the inflamed joints and tendinous sheaths, and more rarely extends to an entire limb, which may not only be considerably enlarged and painful and resemble a milk leg, but may be red, hot, and tender, and excite suspicion of phlegmonous erysipelas. Phlebitis, although infinitely less frequent than in gout, has been observed in acute articular rheumatism.[103] Jaccoud in 1871[104] mentioned the exceptional occurrence of subcutaneous nodosities in rheumatism, which he says Froriep first pointed out;[105] but Homolle states that they had been previously mentioned by Sauvage and Chomel.[106] Since then several independent observers have met with this affection, and Drs. Thomas Barlow and Francis Warner of London have lately written a short valuable paper upon the subject based upon 27 cases which they had separately or conjointly investigated. From their paper the following account is chiefly derived:[107] These nodules may vary in number from one to fifty, and in size from that of a pin's head to the volume of an almond, and are quite subcutaneous, firm and elastic, painless, and freely movable. They are not usually attached to the skin, but to the tendons, deep fasciæ, pericranium, periosteum, etc.; the integument over them is free from heat, redness, and infiltration, although exceptionally tenderness on pressure and slight redness may exist over them. They are found most frequently on the back of the elbow, the malleoli, and margins of the patella, but occur occasionally on the extensor tendons of the hand and foot, the scapular spine and iliac crest, the temporal ridge and superior occipital curved line, the ear, etc. These nodules occur singly or in clusters, and are often symmetrical; they are very rapidly developed in crops or in succession, and last sometimes for a few hours, more frequently from three or four days to four or five months, or even eighteen to thirty months. The original formations may disappear, and be succeeded by fresh ones; and sometimes, when no longer perceptible by touch, they may be found post-mortem. Their development is unattended by pyrexia, unless pleuritis, pericarditis, or other condition coexist to which the pyrexia might {44} be referred. These nodosities do not appear to suppurate or ossify or become infiltrated with urate of soda, and histologically they resemble organizing granulative tissue. As regards their pathological associations, Drs. Barlow and Warner found evidences of rheumatism in 25 out of 27 cases; a morbid condition of the heart existed in all of them, and chorea in 10 of them. Two of the conclusions formulated by the authors just mentioned are of great importance: that these subcutaneous nodosities
