Sclerosing Angiomatoid Nodular Transformation of the Adrenal Gland: A Case Report of a Novel Histopathological Entity
The finding of an indeterminate adrenal mass at radiological investigations is a challenge for physicians. Complex diagnostic work-up, periodic follow-up, or surgical intervention are therefore needed to rule out malignant lesions. Tertiary care hospitals are provided with F-18-fludeoxyglucose (F-18-FDG) positron emission tomography (PET) and F-18-dihydroxyphenylalanine (F-18-DOPA) PET, which aid in the characterization of indeterminate adrenal masses. Nevertheless, the histopathological examination may be required to exclude malignancy or rare etiologies. A 54-year-old woman presented to our clinic 6 months after a cerebral hemorrhage. She was hypertensive and had recently discovered a left adrenal mass of 15 mm during an abdominal ultrasound. Contrast-enhanced CT, following adrenal protocol, revealed a 14-mm adrenal mass without characteristics suggestive of an adrenal adenoma. Tumor markers were negative. Functional tests excluded hormone hypersecretion. An F-18-DOPA PET was negative. An F-18-FDG PET showed mild uptake of both the adrenal glands, with a more circumscribed pattern in the left one (maximum standardized uptake value 5 4). As the clinical diagnosis was still indeterminate, we performed laparoscopic left adrenalectomy. The histopathological examination described a sclerosing angiomatoid nodular transformation (SANT) of the adrenal gland, a benign lesion already described as a rare occurrence only in the spleen. IgG4 levels were reduced. In conclusion, this is a report of a SANT of the adrenal gland, a novel entity that should be taken into consideration in the differential diagnosis of indeterminate adrenal masses at CT scan.

Open adrenalectomy in the era of laparoscopic surgery: a review
Open adrenalectomy still plays an important role in adrenal surgery. A review of the current literature has been carried out to discuss the main indication to open adrenalectomy with regards to the main adrenal pathologies. The authors underlined the role of open adrenalectomy on the basis of personal experience and a literature review. Indication to open adrenalectomy for adrenal cysts, myelolipomas, pheochromocytomas, metastases, adrenocortical carcinomas and tumour recurrences were analysed and discussed. Open adrenalectomy has still an important role in several adrenal pathologies: it is mandatory in some specific situations, such as big lesions, risk of malignancy, emergency settings and in case of recurrent tumoral disease

Development and validation of a preoperative "difficulty score" for laparoscopic transabdominal adrenalectomy: a multicenter retrospective study
BACKGROUND: A difficulty score for laparoscopic adrenalectomy (LA) is lacking in the literature. A retrospective cohort study was designed to develop a preoperative âdifficulty scoreâ for LA. METHODS: A multicenter study was conducted involving four Italian tertiary centers for adrenal disease. The population was randomly divided into two subsets: training group and validation one. A multicenter study was undertaken, including 964 patients. Patient, adrenal lesion, surgeonâs characteristics, and the type of procedure were studied as potential predictors of target events. The operative time (pOT), conversion rate (cLA), or both were used as indicators of the difficulty in three multivariate models. All models were developed in a training cohort (70% of the sample) and validated using 30% of patients. For all models, the ability to predict complicated postoperative course was reported describing the area under the curve (AUCs). Logistic regression, reporting odds ratio (OR) with p-value, was used. RESULTS: In model A, gender (OR 2.04, pâ=â0.001), BMI (OR 1.07, pâ=â0.002), previous surgery (OR 1.29, pâ=â0.048), site (OR 21.8, pâ<â0.001) and size of the lesion (OR 1.16, pâ=â0.002), cumulative sum of procedures (OR 0.99, pâ<â0.001), extended (OR 26.72, pâ<â0.001) or associated procedures (OR 4.32, pâ=â0.015) increased the pOT. In model B, ASA (OR 2.86, pâ=â0.001), lesion size (OR 1.20, pâ=â0.005), and extended resection (OR 8.85, pâ=â0.007) increased the cLA risk. Model C had similar results to model A. All scores obtained predicted the target events in validation cohort (OR 1.99, pâ<â0.001; OR 1.37, pâ=â0.007; OR 1.70, pâ<â0.001, score A, B, and C, respectively). The AUCs in predicting complications were 0.740, 0.686, and 0.763 for model A, B, and C, respectively. CONCLUSION: A difficulty score based on both pOT and cLA (Model C) was developed using 70% of the sample. The score was validated using a second cohort. Finally, the score was tested, and its results are able to predict a complicated postoperative course.
