[Pseudo-conduction block in nonsystemic vasculitic neuropathy].

Summary: Introduction. Nonsystemic vasculitic neuropathy (NSVN) is an inflammatory disorder of the vasa nervorum which usually is expressed as a mononeuritis multiplex. We present a patient with NSVN with histological confirmination focused on the neurophysiological findings at the early stages.

Bcl-2 and CD10 expression in the differential diagnosis of trichoblastoma, basal cell carcinoma, and basal cell carcinoma with follicular differentiation.

Background: Both trichoblastoma and basal cell carcinoma (BCC) of the skin are characterized morphologically by the proliferation of basaloid cells; however, BCCs are clinically associated with a more aggressive behavior. An accurate diagnosis of these lesions is essential for effective, timely treatment and appropriate therapeutic decisions.

Methods: This study includes 40 lesions.

[Chondroblastoma of the carpal scaphoids].

A chondroblastoma is a benign tumour of cartilaginous origin which represents less than 1% of all primary osseous tumours. It is typically localised in the epiphysis of the long bones. Some 10% of chondroblastomas affect the bones of the foot and the hand.

[Modulation of biomarkers expression (OR, PR and C-erbB2) in breast cancer following neoadjuvant treatment].

Introduction: Pre and post-operative oncological therapy in patients with breast cancer is determined, amongst other factors, by hormone receptor status and by c-erbB2 expression. The aim of this study is to determine the influence of neoadjuvant therapy on the expression of oestrogen receptor (OR), progesterone receptor (PR) and c-erbB2.

Methods: Fifty-three patients with breast cancer diagnosed by tru-cut biopsy were studied.

Partial expectoration of a typical carcinoid: report of a case with diagnosis on sputum cytology.

Background: Typical carcinoid (TC) tumors are relatively infrequent. Diagnosis on the basis of sputum cytology is difficult, and there are few cases reported in the literature. Partial expectoration of endobronchial tumors is a rare event that permits their cytologic diagnosis.
