Twenty-four cases showed predominantly either of four subtypes (11 gastric, 7 intestinal, 4 biliary and 2 oncocytic subtype), while the remaining14 cases showed mixture of more than two subtypes. In conclusion, ICPN presented unique preinvasive neoplasm with characteristic histopathologies. Irregular histologies and complicated lesions of ICPN were related to stromal invasion. Juvenile granulosa cell tumor(JGCT) is an uncommon ovarian sex-cord stromal tumor, with diverse clinical, radiological and histopathologic features. The present study describes the clinicopathological and histomorphological spectrum of JGCTs, and highlights the key differentiating features from its mimics. A retrospective analysis of all cases reported as JGCTs during 2011-19 (8years) was performed with detailed evaluation of clinical, histopathologic data and follow-up details. Of a total 115 GCTs reported during the study period, 15(13%) were reported as JGCTs. The mean age at presentation was 17years. Abdominal pain and distension were the most common clinical presentations. Five patients were pre-menarchal with 3 exhibiting precocious puberty. Majority of tumors were unilateral(left>right), solid-cystic, ranging in size from 4 to 20cm. Microscopically, macrofollicular architecture was most frequent (n=12;80%). The tumor cells depicted variable nuclear pleomorphism, small distinct nucleoli and modgood outcome, when diagnosed at an early stage. The optimal dosing of post-operative total knee arthroplasty (TKA) narcotics is unclear. We report on the average narcotic usage in a group of patients treated with an identical multimodal pain protocol following TKA. 49 patients undergoing TKA participated in the survey. Patients with pre-op narcotic use, recent prior total joint arthroplasty or study refusal were excluded. All patients received a spinal anesthetic. No pre-surgery narcotics were given. All received an identical local
