Stony-hard Subcutaneous Nodule

Rheumatic Subcutaneous Nodule Formation.

A WEALTH of literature has sprung up, particularly in the last few years, dealing with subcutaneous nodule formation in acute rheumatism and rheumatoid arthritis, but there is still much difference of opinion as to whether the two are closely related or whether the tissue changes are non-specific and unrelated aetiologically. As Keil (1938) writes, in a very full and comprehensive analysis of t...

Painful subcutaneous nodule.

The patient was a 57-year-old woman who practiced hiking, and had no history of disease. She presented with a subcutaneous lesion measuring 5 mm in the fifth toe of her left foot that she had detected 12 weeks earlier. The lesion was intensely painful and had undergone no changes. Plain radiography of the foot revealed the presence of a small calcification on the lateral border of the distal ph...

Solitary Subcutaneous Nodule over the Right Elbow

DOI: 10.4103/0019‐5154.198029 A 25-year-old male presented with a solitary asymptomatic swelling over the right elbow of six months duration. There was no history of joint pain, breathlessness, diabetes, or any other systemic complaint. He was not on any medication. Cutaneous examination revealed solitary, nontender, subcutaneous nodule measuring 4 mm × 4 mm over the right elbow [Figure 1]. The...

N=2 string amplitudes, when required to have the Lorentz covariance of the equivalent N=4 string, describe a self-dual form of N=4 super Yang-Mills in 2+2 dimensions. Spin-independent couplings and the ghost nature of SO(2,2) spacetime make it a topological-like theory with vanishing loop corrections.
