“…Inflammatory myofibroblastic tumours occurring in the rectum are rare entities, with 6 reports in the English-language literature. [4][5][6][7][8][9] The diagnoses were made on histological evaluation of a biopsy or resection specimen with none having been made on a cytology specimen.…”

Inflammatory myofibroblastic tumour of the rectum with a novel anaplastic lymphoma kinase fusion diagnosed on cytology: Not just another submucosal gastrointestinal stromal tumour!

Inflammatory myofibroblastic tumours (IMT) are spindle cell neoplasms most commonly seen in the lungs, with a wide variety of less common extrapulmonary sites including the mesentery, omentum, and intrabdominal sites. On cytological evaluation, these tumours can be difficult to diagnose, given the morphological mimics of other submucosal spindle cell neoplasms, which may be compounded by the relatively small amount of tissue and the uncommon nature of the diagnosis. Immunohistochemical staining and molecular studies for the ALK gene can prove useful for diagnosing this tumour. We present the cytological features of an IMT occurring in the rectum, the differential diagnoses, useful immunohistochemical staining patterns, and the additional finding of a novel ALK-fusion in this entity.

“…Clinical symptoms are nonspecific, such as nausea, vomiting, anorexia, pain, fever, chills, night sweats, weight loss, and anemia (1, 2, 7–10, 29, 31), or organotypic and site-specific, e.g., dysphagia, gastrointestinal bleeding, obstruction symptoms, especially including intestinal invagination, and icterus (1, 7, 8, 11, 22, 26, 33, 53–55).…”

The liver and biliary tract were the most commonly affected of all body regions, at 32%. This was followed by the lung, including the respiratory tract, at 27%, and by the gastrointestinal tract, at 10%. Lesions of the large bowel, as in the present case of a 9-year-old boy, are very rare. There were organ-related as well as nonspecific clinical symptoms, such as fever, weight loss, and fatigue. Laboratory test results revealed anemia and elevated inflammation-dependent parameters. The patterns in medical imaging are variable and nonspecific. Morphology often suggests a malignant process. For this reason, therapy in most cases is surgical, but this is required more often in IMTs. Many IPTs could be treated conservatively.

Pelvic inflammatory myofibroblastic tumor mimicking a rectal cancer

We report a case of a 50-year-old woman who presented to the emergency department with large bowel obstruction and anemia. The initial imaging study suggested an inoperable rectal tumor with involvement of surrounding structures. In this paper, we discuss the diagnostic work-up of this patient with a diagnosis of pelvic/ perirectal inflammatory myofibroblastic tumor (IMT). IMT is a rare tumor with intermediate malignant potential that frequently mimics clinical and imaging features of malignancy. Additionally, to the best of our knowledge, this is the first case of a pelvic IMT that regressed without surgical excision.
