Diabetic mastopathy (DMP) is an uncommon collection of clinical, radiological, and histological features, classically described in premenopausal women with long-term insulin-dependent diabetes mellitus. This entity can mimic breast carcinoma, but, in the appropriate clinical and imaging setting, the diagnosis can be made by core biopsy, avoiding unnecessary surgeries.We report the case of a 34-year-old female, with a 12-year history of type 1 diabetes, who presented with bilateral breast lumps. Mammography, ultrasonography, and magnetic resonance imaging could not exclude the suspicion of malignancy, and a core biopsy was performed showing the typical histologic features of DMP.The literature is briefly reviewed.

RESUMOOs paragangliomas são tumores raros com uma incidência descrita de 2-8 por milhão. São tumores de células cromafins do sistema neuroendócrino que provêm dos gânglios simpáticos ou parassimpáticos. Apresentamos um caso de uma jovem de 32 anos, nulípara referenciada à nossa Unidade de Infertilidade. No decurso da investigação, na ecografia abdomino-pélvica identificámos a presença de uma massa que se estendia da pélvis ao abdómen, desde ovário direito até junto dos vasos renais, cujo ponto de partida era extra-ovárico (foram identificados os dois ovários com características morfológicas normais). A ressonância magnética revelou uma massa anexial multiquística e muito vascularizada junto aos vasos ilíacos, tendo colocado em hipótese origem ovárica. Desta forma, procedemos a uma laparotomia exploradora e encontrámos uma massa encapsulada, muito vascularizada que se estendia desde o bordo inferior da artéria renal direita até ao ligamento largo direito. A massa foi totalmente removida e a histologia foi consistente com um Paraganglioma. Palavras-chave: Neoplasias Abdominais; Neoplasias Pélvicas; Paraganglioma. ABSTRACTParagangliomas are rare tumors, with a reported incidence of 2-8 per million. They are chromaffin cell tumors that develop from the neural crest cells and may be divided in tumors derived from the parasympathetic or sympathetic ganglia. We report a case a of a 32-year-old nulliparous woman, referred to our Infertility Clinic. Abdomino-pelvic ultrasound identified a large abdominopelvic tumor, without ovarian origin (both ovaries were identified and had normal morphology). Magnetic Resonance Imaging suggested a right adnexal multicystic, vascularized mass close to iliac vessels and questioning an ovarian origin. At exploratory laparotomy, a 10 cm encapsulated and vascularized mass was found beginning just below right renal artery and extending to the level of the broad ligament. This mass was totally excised and histopathology was consistent with Paraganglioma.

The interest around the additive manufacturing is increasing, with more and more solutions at both the industrial and desktop levels. As this is still a relatively recent issue for several industrial areas, there is a clear opportunity to explore in order to optimize the systems in the face of the needs of these same industries, and with increasing times, there are increasing factors to take into ac- count in initial phases of new product development. Presently, there is also a growing ecological awareness, with the concern of implementing a logic of waste reduction and implementation of the circular economy in new products with a view to the valuation of new alternative materials. With the development of solutions aimed at the optimization and feasibility of large additive manufacturing systems, the introduction of new alternative materials will be a reality, presenting in this article a solution and methodology for future tests for new materials. Thus, herein is studied a way of responding to both problems, new ecological materials and BAAM system optimization, presented through a hybrid and flexible solution based on the Pin Bed Forming principle applied to Big Area Additive Manufacturing systems.
