RESUMO
Osteoblastomatosis (OBLT), also referred to as multifocal osteoblastoma (OB), is an unusual and recently described entity consisting of multifocal tumors histologically consistent with osteoblastoma and osteoid osteoma (OO) but radiologically mimicking a vascular bone lesion. OBLT treatment is based on aggressive procedures, such as amputation, en bloc resection, and chemotherapy. Only one previously reported case was successfully treated following a multimodal approach consisting of curettage, cryotherapy, intravenous bisphosphonates, and radiofrequency ablation. We present a case of OBLT that may have been cured by CT-guided percutaneous radiofrequency ablation.

Well Differentiated Papillary Mesothelioma (MPBD) is a very rare neoplasm that mainly affects women of reproductive age. The most common location is the peritoneum and it is an incidental finding, with a generally favorable prognosis. We present three cases diagnosed incidentally, in the course of a surgical intervention of various causes, which presented as peritoneal exophytic lesions not detected in the pre-surgical imaging study. It is important to keep this entity in mind, to differentiate it from other neoplasms with an unfavorable prognosis and evolution, such as Malignant Mesothelioma or primary and metastatic carcinomas. Recent studies give the MPBD a specific immunohistochemical and molecular profile that allow a greater diagnostic precision of the entity.
