Lipoma of the pancreas is a rare benign tumour which is usually discovered incidentally on imaging. We present a case of an incidentally discovered pancreatic lipoma in a 79-year-old man with non-metastatic prostate adenocarcinoma who was referred to radiology for follow-up imaging. Fat-containing tumours originating from the pancreas are very rare. Most lipomas show characteristic features on imaging that allow their differentiation. We present the imaging features of a pancreatic lipoma on ultrasound, CT and MRI, discuss the differential diagnosis, and provide a brief review of the literature., Learning Points: Pancreatic lipoma is a rare mesenchymal tumour that is being increasingly recognized.Pancreatic lipoma is commonly asymptomatic and incidentally detected.CT and MRI allow confirmation of the diagnosis and elimination of other differential diagnoses., Competing Interests: Conflicts of Interests: The Authors declare that there are no competing interests., (© EFIM 2021.)

Brown tumors are rare osteolytic lesions occurring in 1.5-1.7% of patients with chronic end-stage renal failure. They are caused by PTH-induced bone remodeling. We here report the case of a young woman on hemodialysis for chronic end-stage renal failure with painless maxillo-mandibular swellings occurred 7 months before. Clinical examination showed facial deformity with two maxillary and mandibular masses to palpation. Laboratory tests revealed hypocalcemia, hyperphosphatemia with hyperparathyroidism. CT scan of the face revealed multiple osteolytic masses in the maxillary and mandibular bones, with significant bone rarefaction and signs of diffuse bone resorption. The diagnosis of multiple brown tumors of the face was retained based on clinical, biological and radiological features. Brown tumors are a rare entity usually characterized by maxillomandibular involvement in patients with chronic renal failure. Practitioners should suspect them, hence the interest in this study., Competing Interests: Les auteurs ne déclarent aucun conflit d'intérêts., (Copyright: Asmaa Adnane et al.)
