Adrenal gland non-Hodgkin's lymphoma in a patient with pulmonary adenocarcinoma
Although primary neoplasms of adrenal gland are uncommon, adrenal metastases are frequently encountered in patients with malignancy, and lung is the most common primary tumour site. Among primary tumours of the adrenal gland non-Hodgkin's lymphoma (NHL) is a very rare entity. We describe a case of a 79-year-old man with a previous diagnosis of adenocarcinoma of the lung who presented after 2 years with a unilateral adrenal gland mass. A solitary metastasis from pulmonary carcinoma was suspected and a laparoscopic adrenalectomy was performed. Histological examination revealed a diffuse large B-cell NHL. The patient was treated with CHOP regimen plus rituximab and a total remission was achieved. After an 8-month follow-up the patient was free of disease. This is the first reported case of a rare non-synchronous tumoral combination involving lung and adrenal gland, emphasising at the incidental discovery of the NHL during a procedure performed for a pulmonary adenocarcinoma.

Early cytological diagnosis of extranodal stage I, primary thyroid Non-Hodgkin lymphoma in elderly patients. Report of two cases and review of the literature
BACKGROUND:
Primary thyroid lymphomas (PTLs) account for 5% of thyroid malignant tumors and often develop in patients with Hashimoto Thyroiditis (HT). Fine-needle cytology (FNC) is widely used in the diagnosis of thyroid nodules, including those arising in HT. Two PTL cases in HT elderly patients are here described and discussed.
METHODS:
FNC was performed in rapidly enlarged thyroid nodules of 2 elderly patients under ultrasound (US) control. FNC was used to prepare conventional cytologic smears, immunocytochemistry (ICC) and flow cytometry (FC) assessment of cell populations.
RESULTS:
The above cases were diagnosed as well differentiated, small B-cell and diffuse large B-cell thyroid lymphomas, respectively, by means of FNC. The histological diagnoses were mucosa-associated non Hodgkin lymphoma (MALT) and diffuse large B-cell lymphoma (DLBCL), confirming FNC diagnoses, and patients were treated accordingly.
CONCLUSIONS:
FNC diagnosis of PTL is reliable and accurate; it may be conveniently used in the clinical practice since it provides indications for appropriate therapeutic procedures or diagnostic surgery, and avoids to treat benign nodules
Spontaneous non-aortic retroperitoneal hemorrhage: etiology, imaging characterization and impact of MDCT on management. A multicentric study
Purpose: The purpose of this multicentric study is to assess the usefulness of multiphasic Computed tomography in the identification of spontaneous non-traumatic retroperitoneal hematoma (SRH) and its management, with references to the role of interventional radiology.
Materials and methods: From January 2011 to June 2014, 27 patients with SRH were selected. Patients with aortic, traumatic, or iatrogenic source of bleeding were excluded. All the patients were studied with multiphasic MDCT after injection of intravenous contrast. Digital Subtraction angiography and percutaneous embolization treatment were performed.
Results: CT identified SRH in all cases (100 %), showing the source of bleeding in 11 cases (40 %) and pointing out the source of bleeding in 15 cases (55 %). In one case (5 %), the bleeding origin was recognized only at surgery as adrenal source. CT has identified a contrast medium extravasation in the arterial phase in 17 patients (63 %), treated successfully by percutaneous embolization in 13 and by open-surgery in two cases. Two patients died before undergoing intervention and surgery, respectively. Ten patients (37 %) were non-operatively treated successfully with clinical, laboratory, and imaging follow-up.
Conclusions: Multiphasic CT is the gold standard for the identification of a SRH. Recognition of CT signs of active bleeding is the crucial feature influencing the timing of therapeutic treatment. Urgent embolization should be performed in cases of arterial bleeding or contained vascular injuries supplying the retroperitoneal hematoma. Surgery is to be addressed in cases of actively bleeding hematomas associated with complication. Finally, an initial more conservative approach can be adopted in patients without signs of contrast extravasation or low-flow active bleeding. Technical skill, expertise, and recognition of CT signs of arterial active bleeding are critical features influencing patients management
