HighlightsPRMCs are very rare and they share macroscopical and histological similarity to ovarian cystadenomas.It is important to rule out Echinococcosis specially in endemic regions such as South America.Complete surgical excision of the PRMCs is recommended to eliminate the risk of infection, recurrence and malignant degeneration.It is important to remember that cystic fluid spillage has to be prevented due to the uncertain pathology of the tumor in most of the cases.

Introduction: The world is living through an outbreak of an acute respiratory syndrome caused by a new betacoronavirus known as coronavirus 2 (SARS CoV-2), which has been declared an international public health emergency by the World Health Organisation. Cancer patients are a very special population in this setting since they are more susceptible to viral infections than the general population. Several recommendations have been made on this issue, most of them based on expert opinion and institutional experience. It is essential to gather the evidence available for decision making. Objective: To review the evidence available in order to create a multi-institutional position from the perspective of scientific societies in Argentina involved in the management of cancer patients. Methodology: The review included two phases: 1) search and systematic revision of the medical literature; 2) consensus and revision of the document drafted by national scientific societies involved in the management and care of cancer patients using the modified Delphi method. The final results were presented at a videoconference with all the participants. Also, additional comment and recommendations were discussed. The final document was revised and approved for publication by the members of the panel.

These tumors are quite infrequent. Due to the low frequency and the lack of specific symptoms, most adrenal hemangiomas are diagnosed postoperatively.

SUMMARYDistant metastases of differentiated thyroid cancer are unusual; lung and bones are the most frequently affected sites. Soft tissue metastases (STM) are extremely rare. We describe two cases of patients with differentiated thyroid cancer metastasizing to soft tissues. Both patients had widespread metastatic disease; clinically asymptomatic soft tissue metastases were found by SUMÁRIOAs metástases a distância em carcinoma diferenciado de tireoide são raras. Pulmão e ossos são os lugares mais frequentemente atingidos. As metástases em tecidos moles são extremamente infrequentes. Neste artigo, descrevemos dois casos de pacientes com câncer diferenciado de tireoide com metástases em tecidos moles. Ambos os pacientes padeciam de enfermidade avançada. As metástases em partes moles foram assintomáticas e detectadas mediante
