Its occurrence in the subcutaneous soft tissue of the lower extremity has rarely been reported.\u0000\u0000 Case Report: We report a microcystic/reticular schwannoma arising from a subcutaneous lesion on the lower leg of a 33-year-old man. The patient noticed a subcutaneous mass on the right lower leg six months before admission and experienced radiation pain in the left lower leg. Magnetic resonance imaging revealed a well-demarcated mass with 11-mm maximum diameter with low signal intensity on T1-weighted imaging and high signal intensity on T2-weighted imaging in the subcutaneous region of the right lower leg. Histological examination revealed a cellular area at the periphery of the tumor, although the majority of the tumor showed a microcystic/reticular structure within the myxo-collagenous stroma. The current case was well capsulated and did not show an infiltrative growth pattern. In addition, aggregation of foamy macrophages was frequently seen, although it was reported as a rare feature. After complete surgical excision with clean resection margins, the patient is well, with no evidence of tumor recurrence on follow-up after postoperative 14 months.\u0000\u0000 Conclusion: In this case, infrequent findings for microcystic/reticular schwannoma were observed, although the presence of the classical Antoni A area was helpful for the diagnosis of microcystic/reticular schwannoma.\u0000","PeriodicalId":142535,"journal":{"name":"Journal of Case Reports and Images in Pathology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126747293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
