INTRODUCTION With the improved quality and widespread availability of diagnostic abdominal imaging, incidental intra-abdominal lesions (incidentalomas) are being increasingly identified. Our objective was to characterize the clinical features of asymptomatic patients with incidentally discovered pancreatic lesions and to assess the accuracy of preoperative radiologic diagnosis against the final...

STUDY OBJECTIVE To determine the diagnostic yield of histologic specimens obtained by postmortem transbronchial biopsy (TBB) in patients with acute respiratory failure requiring mechanical ventilation. DESIGN Standard postmortem histologic examination of lung tissue specimens. SETTING An urban university-affiliated hospital. PATIENTS OR PARTICIPANTS Thirty patients with diffuse pulmonary ...

introduction: accurate diagnosis of dental pulp conditions plays a key role in selection of an appropriate treatment including conservative vital pulp therapy (treatable pulp) or root canal treatment (untreatable pulp). the purpose of this study was to assess the accuracy of sensibility tests and the correlation of pulp response to sensibility tests with histologic pulp condition . material and...

Controversy surrounds the diagnosis, classification, and therefore the epidemiology of those tumors which have been designated as mesotheliomas. The group includes lesions which are as broadly different as benign fibrous lesions which some authors refer to as fibromas and anaplastic tumors which are extremely difficult to differentiate from peripheral lung cancers. The former are benign tumors ...

Masaharu Fukunaga, M.D. Department of Pathology, the Jikei University Daisan Hospital, Tokyo, Japan Hydatidiform moles With the increased use of ultrasound hydatidiform mole (HM) is being diagnosed at increasingly early stages of gestation. As villous edema is not fully developed, we cannot make a diagnosis of HM by macroscopic observation. Furthermore, microscopically the classic features of c...

Syringocystadenocarcinoma papilliferum (SCACP) is a very rare cutaneous adnexal neoplasm. SCACP presents histologic variability, and it is difficult to establish the diagnosis from a punch biopsy. SCACP has an overall configuration similar to that of syringocystadenoma papilliferum (SCAP). When we diagnose SCACP, the histologic features of SCAP can be contributing and immunohistochemical staini...

DH: dermatitis herpetiformis DIF: direct immunofluorescence INTRODUCTION Dermatitis herpetiformis (DH) is an autoimmune, subepidermal blistering disease associated with gluten sensitivity. It commonly manifests as intensely pruritic papules and vesicles on the extensor surfaces of extremities in a symmetric distribution. Classic histologic findings and data from direct immunofluorescent (DIF) s...

Just as mycosis fungoides is a disease with many different clinical and histologic manifestations, so too are there many inflammatory conditions that mimic this cutaneous lymphoma. Sometimes the best way to “rule out” a diagnosis of mycosis fungoides is to make a firm diagnosis of another condition. The following entities may be confused with mycosis fungoides on histologic grounds, and represe...
