ObjectiveTo summarize the clinicopathological features of microencapsulated/reticular schwannoma.MethodsTwo cases of microencapsulated/reticular schwannoma treated in West China Hospital of Sichuan University were retrospectively collected. The histological and immunohistochemical features were summarized, and the related literatures were reviewed.ResultsTwo cases of microcystic/reticular neurilemmoma diagnosed and treated in West China Hospital of Sichuan University were male. The clinical manifestations were “dull pain in the right lower abdomen” and “mass of left index finger”. Microscopically, the characteristic reticular or cribriform structures were found in all cases, and lymphocytic sheath was seen in 1 case. Immunohistochemical staining showed S-100, glial fibrillary acidic protein (GFAP) and calretinin positive. By February 2020, only 41 cases were reported in the literatures （there were no cases of this group),there was no significant gender difference, the median age was 55 years (11–93 years), and the median size of the lesion was 2.1 cm (0.4–13.0 cm). Most of them were found by accident, without obvious symptoms and signs, and no history of neurofibromatosis type 1 or 2. Microencapsulated/reticular schwannoma in this patients mainly occurs in the viscera, especially in the gastrointestinal tract (mostly in the the colorectal of lower gastrointestinal tract ), most of them were solitary nodular masses without capsule. Microscopically, the boundary was clear, and the characteristic microcapsules and reticular structures were seen. The tumor cells were diffusely expressing S-100 protein, and GFAP and calretinin were expressed in varying degrees. Electron microscopy showed the characteristics of Schwann cells.ConclusionsMicrocystic/reticular schwannoma is a rare subtype of schwannoma, which needs to be differ-entiated from multiple benign and malignant neoplasms. The diagnosis of the tumor is a challenge for the pathologist.
