“…These tumors are most commonly found in the lung, abdomen, and extremities. They occur less commonly in the head and neck region, although they have been reported in the orbit [1,2], maxillary sinus [3,4], larynx [5], tonsil [6], parapharyngeal space [7], and nasal cavity [8]. Our case occurred in the nasal alar area, a site of origin that has not been reported before.…”

“…Tonsillar IMT is rare. In 1984, Weilbaecher et al were the first to report IMTs of the tonsil[12]. We reviewed the English-language literature regarding IMTs of the tonsil from 1984 to 2011, and only six cases were reported (including the case described herein) (Table 1)[9-13].…”

“…Some investigators consider it to be an immunologic response to an infectious agent[16,17]. For tonsillar IMT, two patients were in an immunodepressive state[11,12] and one was a pregnant woman[10]. The patient with IMT of the tonsil, reported by Newman and Shinn (1995), had been on long-term prednisone for asthma and retroperitoneal fibrosis[12].…”

ObjectivesThe etiology of Inflammatory myofibroblastic tumor(IMT) is contentious. In this study, we used computed tomography (CT) to examine tonsillar IMT and further analyzed the etiology of this entity.MethodologyWe presented CT features of left tonsillar IMT and reviewed the English-language literature published between 1984 and 2011.ResultsTo our knowledge, there are only six published cases of tonsillar IMT including the present case. Two patients were asymptomatic at initial presentation. Two patients were taking immunosuppressants, and one was pregnant and in an immunomodulated state. CT of our patient revealed a 2.6 × 1.8 cm irregular soft tissue mass between the left tonsil and the base of the tongue. It did not invade surrounding structures and was not enhanced on contrast-enhanced imaging.ConclusionsTonsillar IMT may be a benign tumor. We suggest that preoperative recognition of tonsillar IMT by CT may be important to avoid unnecessary expanded surgery.

“…Although IMT was initially recognized in the lung [1], it has subsequently been reported in various extrapulmonary organs and sites. In the head and neck the most commonly involved areas are the paranasal sinuses [2] and orbit [3], but IMT has also been described in the tonsils [4], ears, gingiva, pterygomaxillar space and other periodontal tissues [5], being extremely rare in the larynx [6,7]. Laryngeal IMT most commonly involves the true vocal cord [7].…”

Inflammatory myofibroblastic tumor is extremely rare in the larynx and can mimic a malignant process. We present the case of a 62-year-old male who required tracheotomy due to rapidly progressive stridor. Laryngoscopy showed an exophytic, occlusive tumor located in the right true vocal cord. CT showed an expansive mass measuring 2 x2 x1.3 cm3 and occupying the anterior commissure, with glottic progression to the right true vocal cord. The tumor was completely resected with a CO2 laser via a transoral approach. Histologic examination demonstrated extensive ulceration with the presence of granulation tissue. The specimen was mainly composed of spindle cells arranged in a fasciculated pattern with a myxoid background and focal hyalinization. Immunohistochemical studies revealed positivity of spindle cells to vimentin, muscle-specific actin and smooth muscle actin. The patient showed no evidence of disease 24 months after surgery.
