Extrapulmonary Inflammatory Myofibroblastic Tumor (Inflammatory Pseudotumor) A Clinicopathologic and Immunohistochemical Study of 84 Cases
Inflammatory myofibroblastic tumor (IMT) or inflammatory pseudotumor is a spindle cell proliferation of disputed nosology, with a distinctive fibroinflammatory and even pseudosarcomatous appearance.

A retrospective clinical and pathologic review of 174 cases documenting the cutaneous and extracutaneous manifestations in patients presenting from the neonatal period to 20 years of age finds that JXG is a proliferative disorder of dendrocytes, possibly dermal dendROcytes; thus, its clinical and Pathologic similarities to Langerhans cell histiocytosis are not entirely unexpected.
Pleuropulmonary blastoma
Pleuropulmonary blastoma (PPB) is a unique dysontogenetic neoplasm of childhood that appears as a pulmonary and/or pleural‐based mass and is characterized histologically by a primitive, variably
Terminology and morphologic criteria of neuroblastic tumors
As part of the international cooperative effort to develop a complete set of International Neuroblastoma Risk Groups, the International Neuroblastoma Pathology Committee (INPC) initiated activities
Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease)
Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a unique disease of unknown etiology with a childhood predilection that engender a differential diagnosis which includes lymphomatrous, pseudolymphomatous and infectious conditions.
The International Neuroblastoma Pathology Classification (the Shimada system)
The International Neuroblastoma Pathology Committee, which is comprised of six member pathologists, was convened with the objective of proposing a prognostically significant and biologically relevant
Anaplastic Lymphoma Kinase (ALK) Expression in the Inflammatory Myofibroblastic Tumor: A Comparative Immunohistochemical Study
Anti-ALK staining seems to correlate with those IMTs that have the typical tri-patterned histologic appearance and clinical presentation, providing additional support to the premise that IMT is a distinctive clinicopathologic entity within the broad category of inflammatory pseudotumors.
DICER1 Mutations in Familial Pleuropulmonary Blastoma
It is hypothesize that loss of DICER1 in the epithelium of the developing lung alters the regulation of diffusible factors that promote mesenchymal proliferation.
Extrapulmonary inflammatory myofibroblastic tumor: a clinical and pathological survey.
The IMT should probably be regarded as a soft tissue-mesenchymal tumor with an indeterminant or low malignant potential, which is a somewhat indefinite but realistic prognostic category.
Pleuropulmonary blastoma the so‐called pulmonary blastoma of childhood
The designation of pleuropulmonary blastoma is suggested by the authors for these intrathoracic neoplasms of childhood rather than pulmonary blastoma for histogenetic and anatomic reasons.
