Skeletal muscle involvement is rare with the muscles of the extremities being most commonly affected. We present a series of six patients that have attended our Joint Head and Neck Ultrasound and Cytopathology clinic. In these cases, skeletal muscle involvement by NHL was demonstrated in the head and neck region. The ultrasound findings in these cases are presented and discussed.

Following review by the ENT team he underwent ultrasound examination (Fig. 1). This demonstrated multiple hypo-echoic nodules measuring up to 10 mm in short axis diameter. The nodules appeared hypervascular on power Doppler examination. Much less extensive involvement of the right parotid was noted. The submandibular salivary glands were normal and there was no evidence of locally enlarged lymph nodes. In view of these findings, fine needle aspiration (FNA) was performed. Microscopy was consistent with a salivary neoplasm of acinic or ductal type, and excision to allow further assessment was advised.

This paper introduces a CUSUM (CUmulative SUM) mathematical tool for determining trend and applies the technique to 84 consecutive parotidectomies (super®cial, partial or total/near total) performed by one surgeon (J.S.). Using this operation, the paper illustrates how attainment and maintenance of competence in the ®eld of otolaryngological surgery may be demonstrated at differing levels of rigour. The role of the CUSUM in assessing a trainee's surgical progress is also explored.

Tissue diagnosis can be achieved by fine-needle aspiration. Infarction and inflammatory response following fine-needle aspiration is previously described in excision specimens. We describe 7 cases of radiologically infarcting Warthin's tumours in situ in a retrospective analysis of 76 patients, and demonstrate an approximate incidence of at least 9% of infarction following fine-needle aspiration in lesions left in situ. We recommend the possibility of infarction and associated clinical symptoms being incorporated into pre-fine-needle aspiration patient counselling.
