Adrenal leiomyosarcomas are rare mesenchymal tumors of the suprarenal region that are usually diagnosed after they have reached a large size. We report the case of a 62-year-old male with an incidentally found left adrenal mass. Magnetic resonance imaging of the retroperitoneal space showed a heterogeneously enhanced mass, measuring 10x8.2 cm, with characteristics suspicious of malignancy. The patient underwent left radical adrenalectomy after the hormonal evaluation of the tumor due to the high probability of adrenocortical carcinoma. However, microscopic examination of the tumor showed a spindle cell sarcoma. Immunohistochemically the neoplastic cells were found positive for desmin and smooth muscle actin and the diagnosis of a well differentiated adrenal leiomyosarcoma was established. During follow-up the patient presented an aggressive course as he developed bone, liver and pulmonary metastases early postoperatively, which were treated with radiation therapy and chemotherapy. The patient has progressive metastatic disease while on chemotherapy 31 months after surgery.

Background/Aim: To date few cases of smooth muscle-derived tumors of the adrenal gland have been reported and their treatment remains a medical challenge. The aim of this manuscript was to systematically review the literature and present the tumor characteristics and their management in order to provide a standardized approach to their diagnosis and management. Materials and Methods: We searched five databases (PubMed, Scopus, Elsevier, ResearchGate, Google scholar) for relevant articles published until March 2020. Results: Twenty-two cases of adrenal leiomyoma, four cases of adrenal smooth muscle tumor and forty-five cases of adrenal leiomyosarcoma were included. Conclusion: We present the demographic, clinical, radiological, pathological and oncological characteristics and prognosis of tumors of the adrenal gland arising from smooth muscle cells, as well as describe the common clinical investigations and therapeutic modalities that have been reported as part of their management.Adrenal tumors can be detected either incidentally or after investigation of signs and symptoms that they evoke. Generally, they can be histologically categorized as primary tumors of the adrenal cortex or medulla, metastases from other primary malignancies and other tumors of the adrenal gland which originate from connective tissue cells. Adrenal cortical tumors are comprised by (asymmetric) adrenal cortical hyperplasia, adenoma, myelolipoma, adrenocortical carcinoma, oncocytic adrenocortical neoplasms; medullary tumors are comprised by pheochromocytoma, ganglioneuroma, neuroblastoma, ganglioneuroblastoma and teratoma. Connective tissue origin tumors are rarer and are comprised mainly by haemangioma and lymphangioma with a few cases of leiomyoma, lipoma, hemangiosarcoma, lymphoma, leiomyosarcoma and liposarcoma, as reported in the literature. Patients with primary malignancies in lung, breast, kidney, colon, oesophagus, pancreas, liver, stomach or with melanoma can present with adrenal metastases spread from these tumors, which can commonly be found bilaterally (1).Leiomyomas (LM) and leiomyosarcomas (LMS) are mesenchymal tumors that derive from smooth muscle cells. Their benign -leiomyoma or malignant -leiomyosarcoma characterization depends on nuclear atypia and/or pleomorphism, mitotic activity and tumor cell necrosis (2). Leiomyomas and leiomyosarcomas of the adrenal gland comprise a very small percentage of the gland's pathology with very little data available in the literature. The aim of this manuscript was to systematically review the literature and present demographic, clinical, radiological, pathological and oncological characteristics and prognosis of tumors of the adrenal gland arising from smooth muscle cells, as well as describe the common clinical investigations and therapeutic modalities that have been reported as part of their management.

This retrospective cohort study aimed to explore whether paternal age and semen quality parameters affect the embryological and clinical outcomes of ICSI with oocyte donation. A total of 339 oocyte donation (OD)-ICSI cycles were categorized into four groups according to the semen parameter profiles of the male counterparts: normozoospermia (NS, n = 184), oligozoospermia (OS, n = 41), asthenozoospermia (AS, n = 50), and oligoasthenozoospermia (OAS, n = 64). The effect of age, total sperm count, and progressive motility was separately analyzed for reproductive outcomes and compared between the study groups: fertilization, blastulation, and top-quality embryo rate, biochemical and clinical pregnancy, live birth, and miscarriage. A negative correlation between male age and fertilization rate was observed (r s = − 0.23, p < 0.0001), while male age was a significant factor for biochemical pregnancy (p = 0.0002), clinical pregnancy (p = 0.0017), and live birth (p = 0.0038). Reduced total sperm count and lowered progressive motility led to poorer fertilization rates (r s = 0.19 and 0.35, respectively, p < 0.0001) and affected embryo quality (r s = 0.13, p = 0.02, and r s = 0.22, p < 0.0001, respectively). OD-ICSI cycles with asthenozoospermia had significantly lowered success rates in biochemical pregnancy, clinical pregnancy, and live birth (p < 0.05). Our study demonstrated that both advanced male age and reduced progressive motility of spermatozoa exert a significant negative influence on the outcome of assisted reproduction, even in controlled procedures with gamete selection and optimization such as in OD-ICSI. Improvement in treatment strategies and male fertility evaluation requires incorporation of such evidence to obtain better prognosis towards personalized management.

Background: Radiofrequency (RF) thermal ablation is a minimally invasive technique of local mass elimination with variable efficiency. Methods: Ten patients with small primary breast cancer diagnosed preoperatively by core needle biopsy were ablated percutaneously by an RF (Radionics Cool-tip) device operating on impedance control mode. The percent fat-containing area was calculated in each slide of a total of 47 slides introduced to IQ materials software image analysis. Results: Seven of 10 tumors with tumor diameter less than 2.8 cm and fat content less than 12.47% were totally ablated (score 3). One of 10 with 3 cm tumor diameter and 5.45% fat content showed an intermediate degree of ablated tissue (score 2), and the last 2 with 2 cm and 2.2 cm tumor diameter and more than 19.74% tumor fat content were minimally ablated (score 1). Our present exploratory study on 10 patients suggests dependence of the degree of thermal damage on tumor fat content. Conclusions: We conclude that the fat content of small primary breast cancer could serve as a ‘heat sink’ and should be considered as a preventing factor of complete local tumor destruction by RF thermal ablation.
