Inflammatory myofibroblastic tumor (IMT) is a neoplasm of intermediate biologic potential. Only a few cases of IMT in the spermatic cord have been reported. It was earlier included in a wide spectrum of reactive and neoplastic lesions called "inflammatory pseudotumors". It commonly presents as a painless scrotal mass, usually in children and young adults.

Presentation of case:
We present a case of IMT in the spermatic cord who based on clinical, radiological and cytological findings underwent surgical exploration of left scrotal sac. The mass was separate from the left testis and left epididymis, and was closely adherent to pampiniform plexus of veins. Wide excision of the mass was done. Histology and immunohistochemistry suggested IMT.

IMT is a myofibroblastic spindle cell proliferation with chronic inflammatory infiltrate. Surgical exploration is essential as clinically and radiologically benign or malignant nature of mass cannot be distinguished. The diagnosis of IMT is based on the histological features and is substantiated by immunomarkers.

In clinically distinct masses, based on frozen section, either tumor excision or radical orchidectomy can be performed. The prognosis is excellent after complete surgical excision of spermatic cord IMT. Careful long-term follow-up is essential, because of the possibility of recurrence, though rare in this site.

    ABSTRACT: Although rare, paratesticular inflammatory myofibroblastic tumor (IMT) represents the second most common paratesticular mass after adenomatoid tumor and comprises roughly 6% of such lesions. Only approximately four cases have been reported in patients younger than 18 years of age. We report an incidentally discovered paratesticular IMT in a 17-year-old male successfully treated with wide excision and testis sparing. To our knowledge, no recurrence has been reported after complete excision of paratesticular IMT; however, continued follow-up is recommended.

    ABSTRACT: Objectives To present the most important characteristics of inflammatory myofibroblastic tumours (IMTs) arising in different locations of the body with histological correlation. Methods To review the symptoms and main radiological findings of IMTs. On ultrasonography (US), these tumours can appear as hypoechoic or hyperechoic masses and a variable Doppler appearance with increased vascularity. Computed tomography (CT) and magnetic resonance (MR) are the most used imaging tools in their evaluation. On contrast-enhanced CT, IMTs can appear as homogeneous or heterogeneous lesions, with variable enhancement on delayed acquisitions due to fibrosis. These findings are also present on gadolinium contrast-enhanced MR. On T1-weighted and T2-weighted sequences, IMTs usually show low signal intensity reflecting also the presence of fibrotic tissue. Results To show the main clinical symptoms and radiological features of IMTs in different locations: head and neck, lung, genitourinary, hepatic, splenic, gastrointestinal tract, mesenteric, muskuloskeletal. Conclusions Although IMTs in some organs are not uncommon, they are not usually included in the differential diagnosis of masses. Their radiological features suggest malignant neoplasms, whereas they are not. Consequently, this is an underdiagnosed entity and only after an histological exam could a definitive diagnosis be achieved. Teaching Points • Their radiological features suggest malignant neoplasms, whereas they are not • CT and MR imaging are the most used tools in their evaluation • IMT is an underdiagnosed entity • The definitive diagnosis is only after histological exam

    ABSTRACT: The present study reports the case of a 58-year-old male patient who repeatedly presented with hand ulcers that were diagnosed as cellulitis. Upon histological analysis, however, an inflammatory myofibroblastic tumor (IMT) was diagnosed. IMTs rarely occur in the hands. The involved tissue was removed with the tumor, with the exception of the tendons and cutaneous nerve. The involved tendon sheath and epineurium were carefully resected. After 2 years of follow-up, the patient showed no signs of tumor recurrence and the hand function was good. IMTs in the hands are relatively rare, and are often easily misdiagnosed as infection. An early and correct diagnosis is the key to successful treatment. A biopsy is necessary following debridement of the infected lesion, particularly for recurrent infected lesions. The surgical approach should be conservative, in order to maintain maximum hand function.
