Inflammatory myofibrolastic tumor (IMT) is a rare borderline neoplasm. It frequently occurs in the lung but occasionally occurs in extrapulmonary sites such as the genitourinary tract, gastrointestinal tract, breast, salivary glands, sinonasal tract, orbit, and the central nervous system. Laryngeal involvement of IMT is very rare. A 61-year-old woman who complained of hoarseness persisting for 3 months visited our hospital. Laryngoscopy showed an elevated lesion in the right true vocal cord. Incisional biopsy was confirmed as larygeal inflammatory myofibrolastic tumor. We performed a transoral excision with CO₂ LASER under suspension examination. Regional recurrence or distant metastasis was not observed after 9 months of follow-up. Herein we report a case of larygeal inflammatory myofibrolastic tumor that was treated with surgery alone, with a literature review.

Malignant fibrous histiocytomas (MFHs) is the most common type of soft tissue sarcoma in the old animal with a aggressiveness, a high local recurrence rate and significant metastatic rate, which associated with a poor prognosis. In most histologic and immunohistological studies, the tumor cells raised from a fibroblastic and/or myofibroblastic phenotype, presumably from undifferentiated mesenchymal cell origin. MFHs are usually firm and invasive, arising in the subcutis; metastasis depends on tumor grade (many are grade 3) [1,2]. The primary tumor cells are pleomorphic, varying in appearance from fusiform to round. Often nucleoli are prominent and irregular [5]. Extracellular amorphous eosinophilic material may be prominent and likely represents reactive collagen production by the tumor [5]. (omitted)

Inflammatory myofibroblastoma is a solid tumor, occurring mainly to children and young adults, and occupying 0.7% of total isolated pulmonary nodules. Since 1973, several cases about inflammatory myofibroblastoma have been reported. Firstly, this tumor was found in lungs. Then, tumors have been founded and reported in mesentery or cardioesophageal region. Histologically, this tumor can be classified as a benign tumor. However, since this tumor has two characteristics showing malignancy, that is, local invasion and recurrence, malignancy can not be completely excluded. Recently, a patient with pulmonary inflammatory myofibroblastoma underwent surgical resection without any signs or symptoms of recurrence.

Leiomyoma is a common benign tumor from smooth muscle cells, mostly in the uterus. Peritoneal leiomyomas (PLs) are extremely rare and mostly reported as disseminated peritoneal leiomyomatosis. However, to the best of out knowledge, radiologic findings of isolated PL are not reported in English literature. Herein, we introduce the radiologic findings of PL mimicking hepatic mass in a 34-year-old female. CT showed a mass with curvilinear heterogeneous enhancement at the liver's peripheral area. On MRI, the mass showed gradual and heterogeneous enhancement on gadoxetic acid-enhanced MRI and diffusion restriction. The radiologic diagnosis was a benign hepatic tumor, such as degenerated hemangioma, adenoma, and inflammatory myofibroblastic tumor; however, the mass was diagnosed as PL pathologically.
