ABSTRACT
A 30-year-old female presented with a 3-month history of erosive stomatitis and bullous lesions, along with recurrent episodes of abdominal pain. She was found to have a retroperitoneal lump in left lumbar region. Skin biopsy revealed bullous disorder. CT guided biopsy of the retroperitoneal mass was suggestive of inflammatory myofibroblastic tumor (IMT). She was started on oral steroids and supportive care, and surgery was being planned when she developed respiratory failure. CT chest revealed vertebral metastases. PET/CT for whole body work up revealed a left para-aortic mass along with multiple skeletal metastases. The patient was kept on conservative management. After 3 months, the patient has shown clinical improvement, and an exploratory laparotomy is now being planned for the excision of the tumor, followed by chemotherapy. This case of retroperitoneal IMT is rare in terms of skeletal metastases with paraneoplastic pemphigus.

Primary renal lymphoma (PRL) is a rare disease. We here present the case of an 8-year-old child who presented with bilateral renal masses. On biopsy, it was confirmed to be B-cell non-Hodgkin's lymphoma. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography-computed tomography (PET/CT) for staging demonstrated (18)F-FDG avid bilateral renal masses, with no other abnormal focus. Follow up (18)F-FDG PET/CT showed complete resolution of the disease after six cycles of chemotherapy. Here we have highlighted the potential role of (18)F-FDG PET/CT in staging and response evaluation of a patient with PRL and presented a brief review.
