Objective: To assess the patterns of myoinvasion of endometrial endometrioid adenocarcinoma, their frequencies in our hospital and to correlate these patterns with survival. Study Design: Retrospective observational study. Place and Duration of Study: Department of Pathology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Lahore, from Aug 2019 to Apr 2020. Methodology: All cases of endometrial endometrioid adenocarcinoma between 2015 and 2017 were retrieved from the archives, independently reviewed by two researchers, all key reporting parameters recorded in addition to the pattern of myoinvasion as per their operational definitions described by Cole and Quick. The follow-up of 3-5 years was obtained from archives and through telephonic contact for outside hospital patients. Disease free survival and relapse-associated mortality were represented through Kaplan-Meier curves. Results: Eighty cases of myoinvasive endometrial endometrioid adenocarcinoma were reviewed. We found that infiltrating irregular gland pattern was the most frequent in all the age groups. Thirty-five (43.75%) cases showed this type of invasion, followed by broad front pattern 23 (28.75%), Microcystic Elongated and Fragmented (MELF) pattern 15 (18.75%) and adenomyotic pattern 6 (7.5%). One case showed a combination of the last two patterns, whereas adenoma malignum pattern was not seen. Follow-up of these patients showed 8 (10%) patients with relapse related mortality including 5 (62.5%) infiltrating irregular glands, 2 (25%) adenomyosis-like and 1 (12.5%) broad front pattern of myoinvasion. Seventy-two (90%) patients had recurrence free survival. Conclusion: Frequency of infiltrating irregular pattern of myoinvasion in endometrial endometrioid adenocarcinoma is high and associated with recurrence related mortality.

Keratin granulomas in the peritoneum are a rare finding with multiple etiologies and can be especially challenging for both the pathologist and the surgeon when these lesions are grossly visible. We report a case of a unique frozen section diagnostic scenario of evaluation of keratin granulomas in the peritoneum of a 47-year-old woman in the setting of multiple potential culprits: endometrial endometrioid adenocarcinoma following fertility sparing treatment, and a concurrent dermoid cyst. We discuss the various etiologies of keratin granulomas in the peritoneum, mechanism of their formation, diagnostic significance, as well as implications of fertility sparing treatments. To the best of our knowledge, this is the only case of keratin granulomas in the peritoneum with multiple distinct potential pathologic culprits as well the only case following fertility sparing treatment.

BackgroundThe optimal treatment of patients with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma remains unknown.ObjectiveTo compare overall survival following treatment with a hysterectomy and adjuvant radiotherapy with or without chemotherapy in this group of patients.MethodsPatients diagnosed between January 2004 and January 2016 with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma treated with hysterectomy and postoperative radiotherapy with or without adjuvant concurrent chemotherapy were identified in the National Cancer Database. Overall survival was assessed with Kaplan-Meier curves. A Cox model was constructed to evaluate survival after controlling for confounding variables. A logistic regression model was used to reveal predictors of chemotherapy use.ResultsA total of 2173 patients were included. The receipt of chemotherapy was associated with an increased 5-year overall survival from 67.6% to 75.6% (p=0.0313). This association trended toward statistical significance on multivariate analysis (adjusted HR (aHR) 0.80; 95% CI 0.63 to 1.01; p=0.0653). Other factors associated with improved survival were undergoing a lymphadenectomy, absence of lymphovascular space invasion, younger age, smaller tumor size, non-black race, and absence of comorbidities. Patients who underwent brachytherapy, had lymphovascular space invasion, were younger, were diagnosed in the more recent years, and were treated in higher volume centers were more likely to receive adjuvant chemotherapy.ConclusionAdjuvant chemotherapy and radiation therapy were associated with an increase in survival in patients with FIGO stage IB grade 3 endometrial endometrioid adenocarcinoma compared with those treated with adjuvant radiotherapy alone.
