Given the more widespread use of conventional imaging techniques such as magnetic resonance imaging or computed tomography, recent years have witnessed an increased rate of incidental findings in the adrenal gland and those adrenal masses can be either of benign or malignant origin. In this regard, routinely conducted morphological imaging cannot always reliably distinguish between cancerous and noncancerous lesions. As such, those incidental adrenal masses trigger further diagnostic work-up, including molecular functional imaging providing a non-invasive read-out on a sub-cellular level. ⋯ Furthermore, radiolabeled MIBG, DOPA, and DOTATOC/-TATE are radiotracers that are quite helpful in detecting pheochromocytomas originating from the adrenal medulla. Of note, after having quantified the retention capacities of the target in-vivo, such radiotracers have the potential to be used as anti-cancer therapeutics by using their therapeutic equivalents in a theranostic setting. The present review will summarize the current advent of established and recently introduced molecular image biomarkers for investigating adrenal masses and highlight its transformation beyond providing functional status towards image-guided therapeutic approaches, in particular in patients afflicted with adrenocortical carcinoma.

Most cutaneous lymphomas are cutaneous T-cell lymphomas, and the most common form is mycosis fungoides. Sézary syndrome is a leukemic form of cutaneous T-cell lymphoma which is characterized by erythroderma and the presence of blood tumor cells. The only potential cure of cutaneous T-cell lymphomas remains allogeneic stem cell transplantation. ⋯ Lacutamab, an anti-KIR3DL2 monoclonal antibody, is currently tested in an international, prospective phase 2 trial in cutaneous T-cell lymphomas and peripheral T-cell lymphomas. Finally, immune checkpoint inhibitors have shown clinical benefit in open-label phase 2 studies in cutaneous T-cell lymphomas. This review focuses on the new biotherapies currently used in cutaneous T-cell lymphomas.

PCBCLs are a group of Non-Hodgkin's B-cell lymphomas originating in and usually confined to the skin, representing approximately one fourth of primary cutaneous lymphomas (PCL). Their current classification system has been the result of the joint World Health Organization (WHO) - European Organization for Research and Treatment of Cancer (EORTC) consensus in 2018. ⋯ On the contrary, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) is less common, yet more aggressive, with a reported 5-year overall survival of approximatively 50%. In this review, we outline the PCBCLs defining diagnostic criteria, report the features of the less common subtypes and summarize the noteworthy therapeutical options currently available in this field.

Primary cutaneous lymphomas are a heterogeneous group of cutaneous T-cell lymphomas (CTCL) and cutaneous B-cell lymphomas (CBCL) that present in the skin with no evidence of extracutaneous disease at the time of diagnosis. In the last decade the 2005 WHO-EORTC consensus classification has served as a golden standard for the diagnosis and classification of these conditions. ⋯ Herein, the characteristic features of the different types of CTCL and CBCL are presented, differences with previous classification schemes discussed and the results of more recent molecular studies with clinical implications for these conditions reviewed. In addition, an update of the frequency and survival of the different types of primary cutaneous lymphomas is provided.
