“…Al-Hussaini et al[ 24 ] and Kayashima et al[ 30 ] described a contrast-enhancing, hyper-intense well defined lesion without going into details. In four cases the lesion in T1W was mostly hypointense and T2W hyperintense[ 17 , 25 , 26 , 28 ]. Despite its rarity, lack of diagnostic signs and symptoms, IMTL should not be ruled out as a differential diagnosis in liver lesions like focal nodular hyperplasia, hepatocellular adenoma, carcinoma and ecchinococcosis especially in young patients with normal tumor markers[ 7 ].…”

BACKGROUND Inflammatory myofibroblastic tumors of the liver (IMTL) are extremely rare neoplasms and very little is known about their clinical presentation, pathogenesis, and biological behavior. Due to their absolute rarity, it is almost impossible to obtain a definite diagnosis without histological examination. Because of their intermediate biological behavior with the risk for local recurrence and metastases, surgical resection is recommend whenever IMTL is suspect. CASE SUMMARY We herein present a case of an otherwise healthy 32-year-old woman who presented with intermittent fever, unclear anemia, malaise and right flank pain 4 mo postpartum. The liver mass in segment IVa/b was highly FDG avid in the positron emission tomography-computed tomography. Hepatic resection was performed achieving a negative resection margin and an immediate resolution of all clinical symptoms. Histological analysis diagnosed the rare finding of an inflammatory myofibroblastic tumor of the liver and revealed cytoplasmic anaplastic lymphoma kinase expression by immunohistochemistry. Twelve months follow-up magnetic resonance imaging showed no recurrence and no metastases in the fully recovered patient. CONCLUSION IMTLs are extremely rare and difficult to diagnose. Due to their intermediate biological behavior, surgical resection should be perform whenever feasible and patients should be followed-up in order to detect recurrence and metastasis as early as possible.

“…PMPs are similar to nodular fasciitis in its various expressions (proliferative fasciitis, proliferative myositis, and ossificans) [19, 21] and from time to time are labeled under various designations such as visceral fasciitis, pseudosarcomatous fibromyxoid tumor [19], spindle cell pseudomalignant proliferation, postoperative spindle cell nodule [23], and inflammatory pseudotumor [18]. These lesions most often occur in the genitourinary system (bladder, prostate, ureter, vagina, and vulva) [24–26] but can occasionally arise in the gastrointestinal tract [27, 28] or in the organs of the upper aerodigestive tract (pharynx, larynx, nasal cavities, and mouth) [29, 30]. They should be clearly distinguished from the inflammatory myofibroblastic tumor (IMT) [31, 32], and for this reason the confusing adjective inflammatory should be avoided in their description.…”

A 76-year-old man reported a worsening difficulty in swallowing, leading to the inability to eat. Physical examination and CT scan revealed a polypoid mass on the posterior oropharynx and obstructing the oropharyngeal space. Histologically, the surface was ulcerated. In the underlying necrotic rim, there was active granulation tissue, and a proliferation of voluminous, globoid elements with hyperchromatic and irregular nucleus, sometimes arranged in a alveolar aggregate. The core of the lesion contained spindle-like myoid elements in interwoven bundles, with trabeculae of osteoid matrix maturing into calcified bone. Immunohistochemistry documented positivity for cytokeratins, epithelial membrane antigen, and P63 in the globoid elements beneath the necrotic rim; strong and diffuse expression of vimentin, smooth muscle actin, and CD99 and BCL2 in the spindle elements; and complete negativity for cytokeratin 5/6, high molecular weight cytokeratin (clone 34βE12), S100, muscle-specific actin, desmin, CD117, and anaplastic lymphoma kinase. The lesion was morphologically and immunophenotypically classified as a polypoid oropharyngeal carcinoma with ossifying myofibroblastic stromal proliferation.
