Inflammatory pseudotumor of the lung. Ultrastructural and light microscopic study of a myxomatous variant.
A case of a myxomatous variant of an inflammatory pseudotumor of the lung is reported with clinicopathologic findings including its ultrastructure. The pathologic features of inflammatory pseudotumor of the lung are compared with similar tumors arising elsewhere and bear a close resemblance to granulation tissue, which suggests that inflammatory pseudotumors represent a reparative process rather than a neoplastic process. Recognition of this entity is imperative for a correct diagnosis and in order to differentiate it from malignant neoplasm, since only conservative management is necessary for its treatment.
