Most periapical lesions are represented by inflammatory cysts, granulomas, abscesses or fibrous scars. These inflammatory conditions are often termed "endodontic lesions" because pulpal necrosis is the initiating event in their pathogenesis. Although rare, other clinically confusing periapical lesions have been extensively documented in numerous case reports and short case series. These lesions...

The classification of squamous cell carcinomas, based on cellular differentiation features, includes the poorly differentiated epidermoid carcinomas and well-differentiated epidermoid carcinomas. The histogenetic cytologic data clarify conventional cytodiagnosis of poorly differentiated epidermoid carcinomas and poorly differentiated adenocarcinoma, and also eliminate other categories such as l...

Lymphangiomas are benign lesions consisting of abnormal proliferations of lymphatic vessels. Lymphangiomas associated with bone involvement, particularly in vertebral bodies, accompanied by cord compression, are extremely rare, and our literature review yielded only a few relevant reports. We describe a 61-year-old man presenting with progressive paraparesis and sphincter disturbance of 5 month...

BACKGROUND Radial endobronchial ultrasound with a guide sheath (EBUS-GS) has improved the diagnostic outcomes of peripheral lung lesions. However, to our knowledge, reports on the use of EBUS-GS for diagnosis of cavitary lesions are unavailable. Therefore, this study aimed to assess the effectiveness and safety of EBUS-GS for diagnosis of peripheral cavitary lung lesions (PCLLs). METHODS This...

BACKGROUND Historically, female breast carcinoma has been viewed as an etiologically homogeneous disease associated with rapidly increasing incidence rates until age 50 years, followed by a slower rate of increase among older women. More recent studies, however, have shown distinct age incidence patterns for female breast cancer when stratified by estrogen receptor (ER) expression and/or histop...

Longitudinal melanonychia can be caused by melanocyte activation (hypermelanosis) or proliferation (lentigo, nevus or melanoma). Histopathologic examination is mandatory for suspicious cases of melanomas. Tangential biopsy of the matrix is an elegant technique avoiding nail plate dystrophy, but it was unknown whether the depth of the sample obtained by this method is adequate for histopathologi...
