Objectives: To review the results of the first 403 women treated at the Abnormal Smear and Colposcopy Unit with special reference to the utility, efficacy, acceptability and economy of in-office treatment of cervical lesions by large loop or Fischer cone excision. Design: Retrospective chart review of consecutive patients treated following, referral with an abnormal smear or abnormal cervical morphology, between 1 September 1996 and I August 2001. Setting: Inner city private practice. Sample: A total of 403 consecutive General Practitioner referred women. Methods: Details of referral smear result, colposcopically directed biopsy result, subsequent treatment type and histological result including assessability number of specimens submitted, complications and follow-up assessment were extracted at chart review. Costs of public hospital inpatient and outpatient care, supplied by the Casemix and Clinical Benchmarking Service, Mater Miseraecordae Public Hospitals (with permission to publish), were compared with Medicare rebates. Main outcome measures: A total of 187 women were treated by large loop excision of the transformation zone, and 216 by Fischer cone excision. The number of women who were treated as outpatients under local anaesthetic were 395, while eight patients were treated under general anaesthesia as inpatients. There was poor correlation between referring smear, biopsy and subsequent treatment results. Eight patients had abnormal cytology at follow-up, of whom two have been retreated. Three patients had primary or secondary bleeding requiring treatment and two developed cervical stenosis. Outpatient private practice treatment of women with abnormal smears allows significant savings to the public purse over public or private hospital care. Conclusions: Outpatient treatment of women with abnormal smears, using the Fischer cone technique, is safe, wen accepted, effective and the most cost efficient solution to this public health problem.

Background: Parotidectomy is a common surgical procedure performed for a wide array of benign and malignant tumours. The aim of the present study was to review a single-institution experience with parotidectomy over a 10 year period. Methods: We retrospectively reviewed 170 patients who had parotidectomy performed. The preoperative investigations, clinicopathological parameters, perioperative morbidity and mortality were assessed. Results: One hundred and six (62%) of the patients were men. The mean age was 54 years (range 21-80). Indications for parotidectomy included benign tumour (44%), malignant tumour (42%), inflammatory parotid disease (7%) and miscellaneous (5%). The most common benign tumour was pleomorphic adenoma (25%). The most common malignant tumour was metastatic cutaneous squamous cell carcinoma (SCC) (19%). Fine needle aspiration cytology was performed in 83% patients with a sensitivity and specificity for benign tumours of 76% and 97%, respectively. The sensitivity and specificity for malignant tumours was 90% and 99%, respectively. One (0.6%) patient died in the postoperative period. Postoperative complications included wound infection (2.3%), wound haematoma (3.5%) and seroma (6.6%). Six patients (3.5%) developed temporary complete facial paresis, while 33 patients (20%) developed temporary partial facial palsy in the immediate postoperative period. The 2-year disease-free and disease-specific survival for those patients with metastatic cutaneous SCC were 75% and 76%, respectively. Conclusions: The most common indications for parotidectomy were pleomorphic adenoma and metastatic cutaneous SCC. Our perioperative morbidity and survival for patients with malignant parotid disease compare favourably with other institutional series.

Infiltrating syringomatous adenoma (SA) of the nipple is a rare but distinct benign clinical entity affecting the breast. It needs to be included in the differential diagnosis of patients who present with a lump in the nipple/areola complex. It is similar histologically to a syringoma, a benign tumour originating in the ducts of the dermal sweat glands, and importantly needs to be distinguished from a tubular carcinoma. SA of the nipple is locally infiltrating but is not known to metastasise. It often presents as a subareolar lesion with clinical, mammographic and ultrasound findings suspicious for malignancy. Whilst it may be possible to suspect the diagnosis on fine needle cytology, core biopsy or excisional biopsy is usually required to establish the diagnosis. There is a tendency to recurrence if excision is incomplete. The following is a case report, literature review and discussion of the surgical management options available in this unusual condition.
