Describe the clinical appearances of xanthoma tuberosum.
The tubercular variety is commonly met with upon the neck, trunk and extremities. It occurs as small, raised, isolated, yellowish nodules, or as patches made up of aggregations of millet-seed-sized or larger tubercles. The lesions may be few or they may exist in great numbers.
What is the course of xanthoma?
Extremely slow; after reaching a certain development the growths may remain stationary.
State the etiology of xanthoma.
The causes are obscure. Jaundice not infrequently precedes and accompanies its development, especially in the tubercular variety. The disease is uncommon, and is usually seen in middle and advanced life, and more frequently in women. In some cases (xanthoma diabeticorum) of general xanthoma diabetes is the causative factor.
What is the pathology of xanthoma?
It is a benign, connective-tissue new growth, with concomitant or subsequent, but usually partial, fatty degeneration.
Give the prognosis of xanthoma.
The condition is persistent, and usually irresponsive to all treatment save destructive or operative measures.
