ABSTRACT
Muscular echinococcosis accounts for 0.5% to 5.4% of all hydatid disease cases, with very little data on the incidence of muscular echinococcosis of the head and neck. We report a unique case of primary echinococcosis of the right sternocleidomastoid muscle in a 56-year-old man. Preoperative assessment by ultrasound and fine needle aspiration did not point to echinococcosis. We suspected the right diagnosis intraoperatively and confirmed it postoperatively by pathohistology and serologic tests. Echinococcosis of the liver and the lungs was also excluded postoperatively. Combination of operative treatment and postoperative albendazole herapy in two 28-day cycles one month apart resulted in complete regression of the disease. Echinococcosis should be considered as differential diagnosis of a multicystic mass in neck, particularly if it is of longstanding duration. Serologic tests for echinococcosis should be included in differential diagnostic procedures for each multicystic formation on the neck, especially in endemic areas.

Aggressive angiomyxoma is a rare, locally aggressive but non-metastasizing soft tissue tumour which occurs almost, exclusively in female pelvic soft tissues. We report on a tumour occurring in the scrotum of the adult male. Despite a histologically benign picture, wide excision and strict postoperative control are recommended because of the risk of tumour recurrence.

The silver staining technique that identifies NORs (nucleolar organizer regions) associated proteins was used for examining changes in nucleolar organizer region numbers in transitional cell carcinoma of the bladder. This method reveals NORs as black dots in the cell nuclei, and the number of NORs per cell (NORs/cell) has been taught to be related to cellular activation and to be a possible predictor of clinical outcome. A hundred specimens of transitional cell carcinoma of the bladder divided into four histologic grades (Ash classification) with 25 specimens each, and 25 specimens of normal bladder mucosa were analyzed. It has been demonstrated that the amount of protein synthesized by carcinoma varies according to its histologic grade, i.e. the higher histologic grade, the greater the NORs/cell number for each histologic grade. The characteristic mean NORs/cell SD was determined (GI 4.85 +/- 0.82, GII 5.94 +/- 1.42, GIII 8.54 +/- 1.01 and GIV 8.72 +/- 1.42), among which statistically significant differences were found. For similar histologic grades the characteristic mean NORs/cell +/- SD showed no statistically sex and age related differences. In some cases the mean NORs/cell for the examined carcinoma did not match the characteristic mean NPRs/cell +/- SD for the respective histologic grade.
