A Case of Renal Inflammatory Pseudotumor Leading to Nephrectomy

Small Bowel Obstruction as a Result of Inflammatory Pseudotumor

Inflammatory pseudotumor is a rare benign neoplasm that has been described in nearly the entire body and is often mistaken for malignancy. The exact etiology remains unknown. We present a case of small bowel obstruction secondary to an inflammatory pseudotumor. The patient’s symptoms and radiological findings were very concerning for underlying malignancy. En-block resection was recommended to prevent a recurrence. We aim to shed light on this rare cause of small bowel obstruction.

Anaplastic Lymphoma Kinase (ALK)-Negative Inflammatory Myofibroblastic Tumor of the Kidney in a Nine-Month-Old Girl

An inflammatory myofibroblastic tumor (IMT) is an uncommon, benign tumor of myofibroblastic spindle cells. An IMT can occur in any part of the body. However, involving kidney is exceedingly rare. When this rare entity occurs in children, it becomes incredibly challenging to distinguish this rare entity from other malignancies such as Wilms tumor. Although imaging studies of the abdomen and pelvis add to the diagnosis, however, histological examination and immunohistochemical staining remain the gold standard for the precise diagnosis of this rare entity. To the best of our knowledge, only 48 cases of renal IMT have been published in the medical literature so far. We report the case of a nine-month-old girl who was brought with complaints of hematuria, and later, imaging and histological confirmation revealed an anaplastic lymphoma kinase (ALK)-negative IMT of the kidney.
