RESUMEN
Fine needle aspiration cytology (FNAC) especially ultrasound guided has a very important role in diagnosing pulmonary lesions. The present study was undertaken to evaluate the diagnostic efficacy of image-guided percutaneous fine needle aspiration cytology in various lung lesions. This is a three-year retrospective study from August 2010 to July 2013. A total of 322 cases were included in the study. The clinical, radiological and cytological data of all 322 cases who underwent ultrasound guided FNAC were studied. Of the 322 cases in our study, malignancy was the predominant lesion found in 192 cases (59.62%) followed by inflammatory pathology 23 cases (7.1%). Among the malignant lesions, adenocarcinoma was the most common malignancy (26.56%) in females and males followed by squamous cell carcinoma (23.95%). Over the three-year period of the study, 92 cases were grouped under non-specific lesions/inadequate for interpretation. Percutaneous ultrasound-guided FNAC is a relatively safe and accurate procedure in the diagnosis of lung lesion especially peripheral lung lesions.
RESUMEN
Objective To evaluate the effects of δ-aminolaevulinic acid-photodynamic therapy (ALA-PDT) in the treatment of primary carcinomas on the facial skin. Methods In the accordance of these tumors' sites and morphology, 14 patients with squamous cell carcinoma (SCC), 38 patients with basal cell carcinoma (BCC) and 5 patients with Bowen disease were given four to eight times of topical ALA followed by PDT. Results Ten (71.4%) SCC cases, 34 (89.5%) BCC cases and all (100%) Bowen disease cases completely recovered after ALA-PDT. The others all obtained signifi-cant improvement after final treatment. Their unaffected tissues around these tumors kept well and no scaring appeared after ALA-PDT. The recurrence rates among the completely-recovered cases were 10.0% (SCC), 11.8% (BCC) and 0% (Bowen disease), respectively, by the end of six-month's follow-up. Conclusions Topical ALA-PDT is an effective new therapeutical method with lower recur-rence rates, fewer side effects, no scar formation and excellent cosmetic results for primary carcinomas localizing on the facial skin.
