Erythema nodosum is a type of panniculitis that affects subcutaneous fat in the skin, usually first evident as an outcropping of erythematous nodules that are highly sensitive to touch.1 Most nodules are located symmetrically on the ventral aspect of the lower extremities.rythema nodosum nodules vary from 0.4 to 4 inches (1 to 10 cm) in diameter and are poorly demarcated, reflecting their subcutaneous anatomic location (Table 11â4; Figure 1) . Pretibial involvement is most common, although the extensor surfaces of the forearm, the thighs, and the trunk also may be affected.

There are several different kinds of Iwagumi â in Sanzon Iwagumi three stones are used: one larger stone and two smaller flanking stones that lean towards the larger one.
