Adrenal cysts are uncommon and usually asymptomatic, and therefore are usually incidentally discovered adrenal lesions. They have a broad pathohistological spectrum that includes pseudocysts and endothelial (vascular), parasitic, and epithelial (mesothelial) cysts. Although most adrenal cysts are benign and hormonally non-functional lesions, some can have ambiguous imaging appearances and mimic malignant adrenal neoplasms. On the other hand, the actual malignant neoplasms could undergo cystic transformation. Additionally, immune cell infiltrations, thrombosis, or haemorrhage seen in sepsis can frequently cause adrenal cyst development, raising a question about the possible connection between severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) and adrenal cystic lesions. Due to the disease’s rarity, the likelihood of malignancy, and the lack of specific guidelines, the management of adrenal cysts is always challenging especially in a young person. This review discusses the important diagnostic and the current treatment possibilities for adrenal cystic lesions. Aiming to emphasize clinical dilemmas and help clinicians navigate the challenges when encountering a patient with an adrenal cyst in everyday practice, we based our review on a practical question–answer framework centred around the case of a young woman with an incidentally discovered large adrenal cyst.

Introduction/Objective. Male breast cancer is an exceptionally rare disease, accounting for only 0.5% of all male cancer cases, with an incidence of less than one case per 100,000 men annually. This study aims to present the experience of the Institute for Oncology and Radiology of Serbia (IORS) in managing male breast cancer. Methods. This retrospective study included all male patients treated at IORS for breast cancer during the period from 1997 to 2016. In total, 124 cases were included in this study and analyzed regarding demographic, clinical, and pathohistological characteristics, therapeutic approach, and treatment outcomes. Results. Most patients were in stages IIa (27.4%) and IIIb (33.9%). Modified Madden radical mastectomy was performed on 70% of patients. The most prevalent pathohistological tumor type was ductal invasive carcinoma, most frequently in the T2 stage. Most patients (92.1%) had a positive estrogen receptor (ER) and progesterone receptor status (92.1% and 82.4%, respectively), while human epidermal growth factor receptor 2 status was negative in 60% of the patients. The median overall survival was 121 months. Positive ER status was identified as the most important predictor of overall survival, while patients with initial stage IIIa/IIIb/IV disease had a greater risk of disease progression. Conclusion. Our research indicates that patients with ER-positive tumors, who are diagnosed with the disease early and do not have any distant or local metastases have significantly better overall survival rates.

Background/Objectives: Multiple primary malignancies (MPMs) are defined as the occurrence of two or more independent primary tumors in the same patient, histologically distinct and not of metastatic origin. Patients treated for Hodgkin’s lymphoma (HL) carry an increased risk of developing secondary malignancies, especially after chemotherapy and radiotherapy. The synchronous occurrence of breast and kidney carcinoma in this population is extremely rare. Methods: We present a 41-year-old female patient with a history of HL treated at the age of 23 with ABVD chemotherapy and supradiaphragmatic radiotherapy. Results: During staging for a newly diagnosed breast tumor (ER+/PR+/HER2+, pT1cN0), an incidental renal mass was identified and histologically confirmed as clear cell renal cell carcinoma (pT1aNxMx, G2). A multidisciplinary team performed simultaneous partial breast resection with sentinel lymph node biopsy and nephrectomy. The postoperative course was uneventful, and adjuvant systemic therapy was initiated according to oncological guidelines. Conclusions: Synchronous malignancies in HL survivors pose a clinical challenge, as they must be distinguished from metastatic disease and require coordinated therapeutic planning. Risk factors include prior radiotherapy, chemotherapy, genetic predisposition, and family history. This case highlights the importance of long-term surveillance of HL survivors, particularly young women, due to their elevated risk of secondary malignancies. Synchronous breast and kidney carcinomas after HL therapy are extremely rare and demand an integrated multidisciplinary approach. Early recognition and coordinated therapy are crucial for optimizing outcomes and contributing to a better understanding of the etiology and pathogenesis of multiple primary malignancies.

Background/Objectives: Male breast cancer (MBC) is rare, accounting for less than 1% of all breast cancers. Given its low incidence, male breast cancer (MBC) remains understudied; this 33-year Serbian cohort was assessed for clinicopathological features, therapeutic approaches, genetic alterations, and survival. Methods: We retrospectively analyzed MBC patients diagnosed between 1991 and 2024 at the Institute for Oncology and Radiology of Serbia. Data included demographics, tumor characteristics, and stage, treatment, hormone receptor and HER2 status, Ki-67 index, genetic testing, and survival. Results: A total of 191 patients were identified (median age 66). Family history was negative in 91% and positive in 5.8%. T2 tumors were most frequent (36%), and 96% presented without metastasis. Mastectomy with axillary or sentinel lymph node dissection was performed in 78.5%. Neoadjuvant chemotherapy and radiotherapy were administered in 5.8% and 8.4%. Estrogen receptor positivity was 72%, progesterone receptor 88%, HER2 overexpression 11.0%, and triple-negative tumors 2.6% (40% with axillary involvement). High Ki-67 (≥15%) was recorded in 28.8%. Adjuvant chemotherapy, radiotherapy, and hormone therapy were given in 36%, 58%, and 68%. Among 37 genetically tested patients, seven had pathogenic variants (BRCA1, BRCA2, CHEK2, PALB2). Disease recurrence occurred in 30%. Median follow-up was 53 months. Median disease-free survival (DFS) was 82 months (1-, 2-, 5-, 10-year DFS: 87%, 73%, 57%, 39%). Median overall survival (OS) 131 months (1-, 2-, 5-, 10-year OS: 95%, 93%, 73%, 53%). Conclusions: This long-term cohort highlights the predominance of hormone-receptor positivity, the infrequency of germline mutations, and moderate survival rates, informing patient management and guiding future studies.
