Adrenocortical tumors (ACT) are common adrenal tumors. The majority of ACTs are non-functioning and benign, while adrenocortical carcinomas (ACC) are rare, usually very aggressive and often metastasized when first diagnosed. Our aim was to assess whether blood and lymph vessel density within ACTs correlate with the malignancy character or tumor functionality. For that, the microvascular distribution was evaluated by immunohistochemistry staining with D2-40 antibody, for lymph vessels and CD-31 antibody, for blood vessels, in ACCs (n = 15), adenomas with Cushing syndrome (n = 9) and non-functioning adenomas (n = 10)...

Adrenal glands are a common site for metastatic spread since they represent the fourth metastatic site of solid tumors. Interest in local ablative treatments of oligometastases is growing since literature suggests better progression-free survival, quality of life and potentially overall survival in selected patients. Surgery remains the first treatment of adrenal oligometastases because results are good, with a long enough follow-up. However, stereotactic radiotherapy appears to be comparable to surgery and could be proposed to elderly, unfit, inoperable patients, or even to patients whose systemic treatment should not be suspended for too long...

Sarcomas are a heterogeneous group of rare tumors and arise either from soft tissue or from bone. Soft-tissue sarcomas (STSs) initially metastasize to the lungs. Metastases to extrapulmonary sites such as liver, brain, and soft tissue distant from primary tumor usually develop later. However, cases with isolated adrenal metastasis without disseminated disease have been reported in literature. We present a case of primary myxoid liposarcoma of the lower limb, in which staging (18)-F fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan detected a suspicious FDG avid adrenal lesion which eventually on resection was diagnosed as asymptomatic pheochromocytoma...

The most common pattern of esophageal cancer metastases (ECM) is to the lymph nodes, lung, liver, bones, adrenal glands, and brain. On the other hand, unexpected metastasis (UM) spread to uncommon sites has increasingly reported and consequently affected the pathway of diagnosis, staging, and management. Using the PubMed database, a systematic search of the following headings "Esophageal" and "Metastasis" or "Metastases" was performed, 10049 articles were identified, and the articles were included if they demonstrated unexpected ECM...

A 47-year-old man with newly diagnosed nasopharyngeal carcinoma underwent staging F-FDG PET/CT. Apart from showing increased FDG uptake in the primary site and locoregional nodal and liver metastases, an unusual site of intense FDG focus was demonstrated in the left adrenal gland. He underwent CT-guided biopsy, and the histopathologic diagnosis was benign fibrous histiocytoma.

INTRODUCTION: In patients with lung cancer, left adrenal glands (LAG) suspected for distant metastases (M1b) based on imaging require further evaluation for a definitive diagnosis. Tissue acquisition is regularly performed using conventional EUS-FNA. The aim of this study was to investigate the success rate of endoscopic ultrasound guided fine-needle aspiration using the EBUS scope (EUS-B-FNA) for LAG analysis. METHODS: This is a prospective multicenter study in consecutive patients with (suspected) lung cancer and suspected mediastinal and LAG metastases...

INTRODUCTION: In ES-SCLC patients with residual intrathoracic disease after first-line chemotherapy, the addition of thoracic radiotherapy reduces the risk of intrathoracic recurrence, and improves 2-year survival. To identify patient subgroups for future trials investigating higher dose (extra)thoracic radiotherapy, we investigated the prognostic importance of number and sites of metastases in patients included in the CREST trial. MATERIALS/ METHODS: Additional data on sites and numbers of metastases were collected from individual records of 260 patients from the top 9 recruiting centers in the randomized CREST trial (53% of 495 study patients), which compared thoracic radiotherapy (TRT) to no TRT in ES-SCLC patients after any response to chemotherapy...

The most frequent sites of distant metastasis of colorectal cancer (CRC) are primarily liver and lung, followed by brain and bone metastases. Infrequently, metastases are found in the adrenal glands. They usually have a metachronous and homolateral character. We present a case of contralateral synchronic adrenal metastasis of CRC and its surgical resolution.

The purpose of the present retrospective study was to investigate whether a score reflecting systemic inflammatory processes [the Glasgow Prognostic Score (GPS)] provides relevant information for radiation oncologists. GPS is a three-tiered score [0: normal C-reactive protein (CRP) and albumin; 1: one abnormal result; 2: increased CRP and low albumin]. Correlations between disease type and extent, resource utilization, survival and GPS were analyzed in 703 patients. In the subgroup with GPS 2, significantly higher rates of lung, adrenal gland and liver metastases were observed...

INTRODUCTION: Adrenal neoplasms comprise about 10% of all tumours affecting this organ and constitute a significant, at first diagnostic and subsequently therapeutic, problem, especially since a relatively high proportion of neoplastic lesions are asymptomatic. The number of diagnosed metastases to adrenal glands is increasing. Surgical treatment involves both open surgery as well as laparoscopy. MATERIAL AND METHODS: There were 235 adrenalectomies performed at our centre due to various indications over the past four years...

Thyroid transcription factor-1 (TTF-1) is a specific and sensitive marker for canine pulmonary tumors but is also expressed in thyroid carcinomas, which commonly metastasize to lung. Napsin A and surfactant protein A (SP-A) are used in the histologic diagnosis of non-small-cell lung cancer in humans but have not been thoroughly evaluated in neoplasms of dogs. The objective of this study was to compare the efficacy of immunohistochemistry for SP-A, napsin A, and TTF-1 in the diagnosis of canine pulmonary carcinomas...

Testicular seminoma is the most common malignant tumor of the testis. It classically manifests as a painless mass. Radiologic evaluation with high-frequency ultrasonography (US) is critical for diagnosis. Seminomas are usually homogeneously hypoechoic masses at US. In challenging cases, magnetic resonance (MR) imaging may help confirm that a mass is intratesticular and provide data for local staging. Computed tomography (CT) provides valuable information for staging, including the presence and size of retroperitoneal lymph nodes...

Renal angiomyolipomas are the most common renal mesenchymal tumors. While classic angiomyolipomas are benign, there are a number of other subtypes. Epithelioid variants are potentially malignant and may be indistinguishable from renal cell carcinoma on imaging. We present a 52-year-old woman who underwent left nephrectomy for an aggressive-appearing malignant renal epithelioid angiomyolipoma. At 6 months postoperatively, restaging FDG PET/CT demonstrated a hypermetabolic left adrenal mass extending to the left adrenal vein, left renal vein, inferior vena cava, and right atrium (SUVmax = 12)...

Adrenal masses pose a diagnostic challenge. The differential diagnosis includes functional adrenal tumors, incidentally found adrenal masses, metastases from an unknown primary cancer, and abscesses. Infrequently, adrenal gland abscesses have been reported in disseminated nocardiosis affecting immunocompetent and immunocompromised patients. We report a case of disseminated Nocardia farcinica pneumonia with an adrenal gland abscess in an immunocompetent patient with no identified risk factors for nocardiosis...

Lung carcinoid tumors account for approximately 2% of lung cancers, with 10% of the tumors represented by the atypical type. While atypical carcinoids are metastatic to intrathoracic lymph nodes in approximately half of the cases on the initial presentation, distant metastases are seen in only 20% of the patients and are found most frequently in bones, liver, adrenal glands, and brain. We present a case of an unusual metastatic disease to the breast in 51-year-old female who developed a new breast mass 2 years after left lower lobectomy due to atypical carcinoid tumor...
