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.
David Beaulieu. Xeriscape landscaping or, simply, xeriscaping, by definition, is landscaping designed specifically for areas that are susceptible to drought, or for properties where water conservation is practiced. Derived from the Greek xeros meaning dry, the term means literally dry landscape..
Xeriscaping, that is landscaping to reduce or totally eliminate the need for watering by using drought resistant or tolerant plants, can be incorporated into an existing property in a cost-efficient manner but would be a questionable practice immediately after purchasing a home that is already landscaped.
