Xanthogranulomatous endometritis: A case report and literature review.

Xanthogranulomatous endometritis is a rare benign pathology mimicking endometrial carcinoma.

Intra-cranial efficacy of brigatinib in an ALK-positive non-small cell lung cancer patient presenting leptomeningeal carcinomatosis.

OBJECTIVES: Brigatinib is a second-generation ALK inhibitor which demonstrated activity over crizotinib-resistance, especially on brain metastasis by increased blood-brain penetration. However, its activity on lepto-meningeal disease is unknown and scarcely reported. MATERIALS AND METHODS: We hereby report the case of lepto-meningeal disease in crizotinib- and ceretinib- treated patient who was successfully treated by brigatinib. RESULTS: The patient achieved intracranial response to brigatinib more than 14 months. CONCLUSION: Our case provides additional data on brigatinib's intracranial activity, not only on brain metastasis but also on leptomeningeal disease, after experiencing resistance to both crizotinib and ceretinib, 1st and 2nd generation ALK inhibitors.
