Aims:To apply reticulin algorithm (RA) to the diagnosis of adrenocortical tumors on adrenalectomy specimens and compare its efficacy to the modified Weiss criteria or Lin–Weiss–Bisceglia (LWB) criteria for oncocytic variant.Materials and Methods:Adrenocortical tumors (ACTs) diagnosed on resected specimens including the variants during January 2010–June 2016 were retrieved from the pathology records. The demographic and clinical data were obtained from medical records. The functional status of the tumor was noted based on clinical and biochemical evaluation. The location, size, and gross appearance of the tumor were noted. The corresponding hematoxylin and eosin-stained slides were independently assessed by two pathologists applying modified Weiss criteria and LWB criteria for the oncocytic variant as applicable. Reticulin stain was performed on representative sections in all cases. All the tumors were classified according to RA, and the diagnoses made by each system were correlated.Results:There were 15 ACTs in the study period. There were two adenomas including one oncocytoma which showed Weiss score (WS) of 2 and intact reticulin framework. There were 13 adrenal cortical carcinomas including two oncocytic variants with WS ranging from 4 to 7. There was disruption of reticulin and thick, irregular reticulin fibers in all tumors, irrespective of the histology. It correlated with modified Weiss and LWB criteria.Conclusions:The RA was simple, easy to apply, and correlated well with modified Weiss criteria in the diagnosis of ACTs including the oncocytic variant.

Adequate lymph node harvest in resected colorectal cancer (CRC) specimens is important in staging and choosing appropriate therapeutic options. The yield of lymph nodes and metastatic nodes by methylene blue dye injection in 30 randomly selected resected CRC specimens was compared with an equal number of CRC specimens (control) with matched grade and stage.The mean number of lymph nodes retrieved in the study group was 22 ± 9 compared to 17 ± 8 in the control group which was statistically significant (P = 0.04).Methylene blue technique is an effective aid in increasing the yield of lymph nodes in the resected CRC specimens.
