    BACKGROUND/AIMS: The development and widespread use of abdominal imaging techniques has increased the incidence of unexpected adrenal tumors called adrenal incidentaloma. Adrenal myelolipomas are the second most common incidentalomas. Similar myelolipomatous morphology appears as a secondary degenerative change in other adrenal lesions and is called myelolipomatous metaplasia. This study investigated the adrenal entities of the last 13 years which had myelolipomatous components.MATERIALS AND METHODS: In this retrospective observational study, cases diagnosed as adrenal myelolipoma or myelolipomatous metaplasia between January, 2009 and January, 2022 were re-examined regarding their age, gender, localization, lesion size, and secondary histopathological changes, accompanying pathological diagnoses as well as clinical and radiological data.RESULTS: Eleven adrenal myelolipoma cases and 6 myelolipomatous metaplasia cases were detected. In myelolipomas, the mean age was 55.45 years, 73% were female and 82% were located on the right side. The lesions were encapsulated and their mean size was 7 cm. One case had a diagnosis of subclinical Cushing's syndrome and the others were hormonally inactive. Some cases were accompanied with hypertension (27%), type 2 diabetes (18%), and asthma (18%). All myelolipomatous metaplasias, which are non-encapsulated, were detected in adrenocortical adenomas. The mean age was 58 years; nonencapsulated and 67% were located on the right side with no gender predilection. Concomitant hypertension (50%), diabetes /33%, and asthma (33%) were frequent.CONCLUSION: Adrenal myelolipoma and myelolipomatous metaplasia both contain adipose and myeloid components. Myelolipoma is a benign and encapsulated neoplasia which is usually detected incidentally. They frequently coexist with chronic diseases such as hypertension, diabetes and asthma.

    Is it possible that we can increase the lymph node number in cases with rectum tumor receiving neoadjuvant therapy?

    Background: Though the recommended sampled lymph node number in colorectal carcinomas is at least 12, due to shrinkage after preoperative neoadjuvant chemoradiotherapy (NCRT), it can be difficult to attain that number. Aim: Our aim is to increase the lymph node number by applying alcohol fixation on the formalin-fixed resection materials of the patients that received or not received neoadjuvant therapy and to evaluate the changes in staging due to obtained lymph nodes. Settings and Design: Non-randomized controlled trial. Materials and Methods: Lymph node dissection was performed in the resection materials with rectum tumor which were formalin- and afterwards, alcohol-fixed. The number of lymph nodes obtained by both of the methods and status of metastasis were evaluated statistically. Results: Of the total 76 rectal tumors, 57 had and 19 had not received NCRT. The number of lymph node was adequate in 89.5% cases with no NCRT and in 63.2% cases with NCRT. While no change was observed after the alcohol fixation in the cases fulfilling adequacy criterion among those with no NCRT (p = 1.000), the adequacy rate increased from 63.2% to 87.7% in those with NCRT (p < 0.001). Although statistically insignificant, there was a change in pN stage in eight cases. In three of them, the stage varied from pN0 to pN1c, and in five cases, from pN1a to pN1b. Conclusion: Using solutions as alcohol during fixation might facilitate the identification of metastatic lymph nodes, might change the stage of the disease and therefore, might affect the patient-based therapy.
