Abstract

Thymomas are usually found in the anterior thorax as encapsulated, smoothly surfaced or coarsely lobulated tumors, consisting of firm, gray-white to pink-white tissue which does not adhere to adjacent tissue. Their diameter can be up to 3 cm. Smaller tumors are generally found incidentally. They are seen as distinct nodules or as local thickening in the thymus, which disturb the symmetrical appearance of the organ. Larger tumors are more likely to cause clinical signs and be a possible cause of death due to compression of intrathoracic organs. Rarely, gross infiltration of the tumor into the surrounding tissues is seen. Careful collection and examination of residual normal thymus tissue is often helpful in differential diagnosis.
