In males, primary germ cell tumors typically present as a testicular mass [1]. On a few occasions, the primary testicular tumor can regress leaving behind only residual testicular scarring, despite the presence of widespread metastatic disease. This scenario represents a “burnt-out” testicular tumor, also known eponymously as an “Azzopardi tumor” (Fig. 1) [2]. In 1961, Azzopardi et al. reported a series of 17 cases of young men who died of metastatic germ cell tumors, in whom the primary testicular lesion was a fibrous scar with minimal or no viable neoplastic tissue, when examined pathologically [2]. These scars often contained calcium, and it was theorized that the primary tumor had infarcted due its propensity for local vascular invasion, with the resulting necrotic area forming a matrix conducive to calcium deposition [2]. When the “burnt-out” appearance is identified sonographically, it should prompt evaluation of the chest, abdomen, and pelvis for metastatic deposits (Fig. 2).
WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.
Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
