We report scanning electron microscopy (SEM) for a case of parameatal urethral cyst. A 6-year-old Japanese boy presented with a cyst on the right lateral side of the urethral meatus. Histological examination revealed a cyst lined with columnar epithelium. An immunohistochemical study showed positive staining for CK7, CK13, and CEA, and negative for CK20 in(More)
We report a case of human protothecosis in an immunocompromised host which was caused by Prototheca wickerhamii and was successfully treated with thermal adjunct therapy combined with systemic itraconazole therapy. A 78-year-old man taking 30 mg prednisolone daily had a 1-week history of erythematous plaques on the dorsal aspect of his right hand and(More)
Pathological changes of cerebral microvessels in transient ischemia were investigated by scanning electron microscopy of vascular corrosion casts. Wistar rats were treated with middle cerebral artery (MCA) occlusion for 30 min, 1 h, 3 h, 4 h, 5 h or 7 h and subsequent reperfusion for 2 h. The ultrastructures of the cast were observed and computer-aided(More)
We investigated the time course of ultrastructural changes of mitochondria in the spinal cord of homozygotes of Leu126TTdel SOD1 (superoxide dismutase 1) with FLAG (signal sequence at the C-terminal protein) transgenic mice (DF-homo). Non-Tg mice and wild-type human SOD1 with FLAG epitope transgenic mice (WF) were investigated as controls for non-onset Tg(More)
Syringocystadenoma papilliferum is a rare benign adnexal tumor that most frequently arises from an organoid nevus on the head and neck. Occurrence of this tumor on the male breast is extremely rare. A 74-year-old Japanese man presented with a nodule on his left nipple. Histopathological findings were typical for syringocystadenoma papilliferum.(More)
Herein, we report the investigation of two cases of atypical fibroxanthoma (AFX). One AFX developed within actinically damaged skin, as is typical, while the other developed within a burn scar within non-sun-exposed skin. The two tumors showed almost identical histopathological, immunohistochemical and ultrastructural features. The tumors were composed of(More)
Solar lentigines (SL) are hyperpigmented lesions generally seen in elderly people. Their pathogenesis has not been completely elucidated. We examined 75 cases of SL using routine histopathology and immunohistochemistry. In addition, seven cases were evaluated by electron microscopy. Histopathologically, we observed vacuolar changes in the dermoepidermal(More)
The three-dimensional architectures of the perigemmal cells and their keratin bundles in the rat circumvallate papillae were studied by transmission and scanning electron microscopy. The perigemmal cells were classified into three layers: basal, middle and upper. The basal layer consisted of polygonal cells located close to the basal lamina, the middle(More)
Scales from lesional skin of 12 patients with tinea pedis were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to gain an insight into the spatial and morphological changes of dermatophytes after application of a clinical dosage of topical luliconazole 1% cream (Lulicon® cream 1%). In all cases, Trichophyton(More)
We studied corresponding structures on the oral and basal surfaces of the oral epithelial layer, focusing on the microanatomy of gustatory papillae. Specimens for scanning electron microscopy were obtained from the rat soft palates and fixed with a mixture of 2% paraformaldehyde and 1% glutaraldehyde. They were first prepared without postfixation and(More)
