الحبيبومات الجلدية والآفات المتعلقة بها دراسة تشريحية مرضية مقارنة

Our study analyses the distribution of cutaneous granulomas in patients admitted to Alassad University Hospital in Lattakia between 2000 and 2005 to define their morphological characteristics and provide different diagnoses. The study included 41 patients, 27 males and 14 females, whose age ranged from 4 to 70 years. The morphological study was conducted using light microscopy; and the preliminary diagnosis was made by H&E stain procedure. We then used special stains to reach the final diagnosis. During the study we found that 21 cases were cutaneous Leishmaniasis (51.22%), 5 cases were Sarcoidosis (12.20%), 5 cases were foreign body granuloma (12.20%). In conclusion our study reveals that each granulomatous lesion has many histological features, and the positivity of special stain confirms the diagnosis, but negativity did not exclude it. Thus, the clinical and laboratory information is very important, in addition to specific and sophisticated pathological techniques.
