Cellular schwaninoma is a variant of schwannoma, which is characterized by predominance of cellular Antoni A area, presence of mitotic activity, nuclear hyperchromasia, pleomorphism, and absence of Verocay body. These pathologic features often prompted a misdiagnosis of malignancy. However, the clinical outcome has indicated the benignity of the tumor. We have experienced a case of cellular schwannoma arising from right facial nerve with right hemifacial weakness and erosion of mastoid process. Grossly, it was a 3.5 x 3 cm sized and relatively well encapsulated mass with yellowish, friable cut surface. Microscopically, cellular growth with moderate cellular pleomorphism and some mitotic activity (5/40 HPFS, up to 2/HPF) were noted. Immunostaining for S-100 protein showed diffuse strong positive reaction.

AbstractAbstract PDF
Ectopic paragonimiasis has been diagnosed in many organs such as the mesentery, ovary, pleura, central nervous system, subcutis and very rarely in the liver. However, simultaneous involvement of the colon and liver, which mimics colonic cancer with liver metastasis, is quite unusual, and to our knowledge has never been reported. Our case is a 63 year old woman who visited our hospital because of upper abdominal pain. Radiologically, space occupying lesions were detected in the transverse colon, mesocolon and left hepatic lobe. After the radical presection, they were proved to be an ectopic paragonimiasis forming multiple cavitary parasitic granulomas with Charcot-Leyden crystals and degenerating eggs.
