Background: Inflammatory myofibroblastic tumor is a rare occurrence in general practice. Its biologic nature, natural history and response to different treatment modalities are obscure. Materials and Methods: We retrospectively reviewed clinical and pathological features of 5 patients with inflammatory myofibroblastic tumor of the lung observed between 1999 and 2006. Results: Under-study patien...

BACKGROUND Inflammatory myofibroblastic tumour (IMT) is a mesenchymal neoplasm of intermediate biological potential that may affect a wide range of anatomic sites but has a particular predilection for the lung and intra-abdominal soft tissues. CASE PRESENTATION We report here an exceptional case of inflammatory myofibroblastic tumor arising in the lacrimal gland and presenting as an orbital m...

The identification of novel, oncogenic gene rearrangements in inflammatory myofibroblastic tumor demonstrates the potential of next-generation sequencing (NGS) platforms for the detection of therapeutically relevant oncogenes across multiple tumor types, but raises significant questions relating to the investigation of targeted therapies in this new era of widespread NGS testing.

An intracranial cyst tumor with a mural nodule can be representative of some types of brain tumors, but is a rare presentation of intracranial inflammatory myofibroblastic tumor (IMT). Herein, we report the case of an intracranial IMT in a 48-year-old woman presenting with the extremely unusual radiologic findings of a cyst with a mural nodule.

Angiomyofibroblastoma-like tumor is a rare mesenchymal tumor of men. It commonly occurs during the fifth to eighth decades of life and mainly involves the inguinoscrotal region. It is derived from perivascular stem cells and has capacity of lipoid and myofibroblastic differentiation. Histopathologically this tumor in the male genitalia mimics female angiomyofibroblastoma but the...

Inflammatory myofibroblastic tumors rarely occur in the urinary bladder. These masses follow an indolent course, but due to their histologic similarities to more malignant types of bladder masses, they must be differentiated with immunohistochemical staining. Once diagnosed, the mainstay of treatment for these masses is surgical resection. Due to advancements in robotic surgery, new surgical te...

Inflammatory myofibroblastic tumor (IMT), which usually affects young adults and children, is a solid neoplastic mesenchymal proliferation composed of myofibroblastic spindle cells admixed with inflammatory infiltrates. Numerous extrapulmonary sites of these tumors have been found, but intestinal IMT is rare, especially in elderly patient. Its diagnosis is recognized as difficult because the pa...
