BACKGROUND Early post-transplantation alterations in liver tests are caused by a variety of etiologies including rejection, biliary or vascular complications, and preservation/reperfusion injury (PRI). OBJECTIVES The aim of this study was to show the correlation between histopathologic changes of PRI and the alterations in liver tests in the early post-transplantation period. MATERIALS AND ...

Main Outcome Measure: Frequency of dermoscopic patterns within the different histopathologic subtypes of Spitz nevi. Results: Overlapping clinical, dermoscopic, and histopathologic findings were observed among PSN, RN, and PSRN, thereby justifying their inclusion into the single PSRN diagnostic category. Asymmetry was the most frequent indicator of histopathologic ASN (79%; n=11); in only 4 cas...

Purpose. The aim of this study was to prospectively evaluate whether FDG-PET allows an accurate assessment of histopathologic response to neoadjuvant treatment in adult patients with primary bone sarcomas. Methods. Twelve consecutive patients with resectable, primary high grade bone sarcomas were enrolled prospectively. FDG-PET/CT imaging was performed prior to the initiation and after completi...

Objective. To determine the long-term histopathologic changes in nasal mucosa and the relationship between progression of the histopathologic changes and the duration without air current stimulation. Material and Method. Biopsies were taken from the inferior turbinates of 11 laryngeal cancer patients after total laryngectomy. Specimens were stained with hematoksilen-eosin and several histopatho...

BACKGROUND Intracranial tumors with heterogeneous histopathology are a well-described pathologic entity. Pathologically, distinct tumors in direct contact with one another, also known as collision tumors are exceptionally rare, and collision between meningioma subtypes has not been previously described in the literature. CASE DESCRIPTION A 79-year-old female with a history of breast carcinoma...

OBJECTIVE To determine the usefulness of "routine" lacrimal sac biopsy to evaluate unsuspected neoplasm or systemic disease in patients with acquired nasolacrimal duct obstruction. DESIGN Noncomparative, interventional case series with histopathologic correlation. PARTICIPANTS Review of charts revealed histopathologic reports on 302 specimens from 258 patients who had undergone routine dacr...

BACKGROUND 'Persistent pruritic papules and plaques' of Still's disease represents a recently described eruption seen in a subset of patients. Most cases reported in the literature to date have been associated with adult-onset Still's disease. METHODS We present the clinical and histopathologic examinations of three female patients ranging in age from 15 to 54 years. RESULTS Our three patie...

background there is evidence of a possible etiological role of human papillomaviruses (hpvs) in the development of colorectal cancer. loss of p53 tumor suppressor gene function has been found in many malignancies and it can occur in a variety of ways, including gene mutation and interaction with the e6 protein of oncogenic hpvs. the objective of this study was to determine the prevalence of hpv...
