ABSTRACT Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the commonest types of non-melanoma skin cancer (NMSC). The incidence of NMSC has been increasing globally with Australia recording a 1.5-fold increase over the last 17 years. The incidence of NMSC in New Zealand is currently unknown. Given that Australia and New Zealand share similar latitude, sun exposure levels, and other risk factors, it is conceivable this increase has also occurred in New Zealand. This study aimed to provide an analysis of the incidence of NMSC within the Central Region of New Zealand based on longitudinal data derived from pathology reports.
This retrospective study examined the pathology records of 26 411 patients who underwent surgical excision for 54 004 NMSC lesions which were histologically confirmed, over a 10-year period from 1 January, 1997 to 1 January, 2007, within the Central Region of New Zealand.
Over the study period, 50 411 primary NMSC lesions were excised. The age-standardized incidence for NMSC, BCC and SCC was 406, 299 and 118 per 100 000, respectively. Since 1999, the annual incidence of BCC and SCC has increased by 4.0% and 1.1%, respectively, with the greatest increases seen in the population over the age of 50 years.
New Zealand has one of the highest incidence of NMSC in the world. The high and increasing incidence of NMSC underscores the importance for the development and implementation of a national health-care delivery model, and a commitment to continued monitoring of the NMSC problem.

    ABSTRACT: Atypical fibroxanthoma (AFX) and malignant fibrous histiocytoma (MFH) are soft-tissue tumours with variable aggressiveness. There is considerable debate about the relationship between these lesions, as histological and immunochemical differentiation is difficult. Current opinions and evidence for diagnostic differences between AFX and MFH were reviewed. Consecutive cases of AFX and MFH were identified from our non-melanoma skin cancer (NMSC) database 1996-2007 for the Central Region of New Zealand. Of the 50,411 NMSC lesions excised surgically from 26,138 patients, there were 101 AFX and 15 MFH cases. Three MFH cases were originally diagnosed as AFX. AFX and MFH share similar patient demographics, size and location and histological and immunohistochemical features. Most diagnostic biopsies of AFX were not followed by formal excision. Incomplete excision occurred in a large proportion of patients with AFX, which often did not proceed to re-excision, resulting in local recurrence. Cases of MFH generally underwent definitive treatment including re-excision if incompletely excised, and postoperative adjuvant radiotherapy. The failure to treat AFX adequately may have resulted from the lack of appreciation of its aggressiveness. Contrary to the literature, we found few clinical differences between AFX and MFH. AFX and MFH also share similar histologic features and there are no immunohistochemical markers that reliably distinguish them. AFX is best considered a distinct entity with MFH, now reclassified as an undifferentiated pleomorphic sarcoma.

    ABSTRACT: BACKGROUND: Upper eyelid paralysis leads to lagophthalmos with the risk of exposure keratitis, corneal ulceration and blindness. METHODS: Consecutive patients undergoing gold weight implantation and/or lateral tarsorrhaphy were identified from our prospective database and reviewed. RESULTS: Sixty-three patients were identified, 36 of whom underwent immediate reanimation procedure either during cancer excision (n = 35) or repair of facial laceration (n = 1). Twenty-seven patients had a delayed procedure either following tumour excision (n = 21) or unresolved Bell's palsy (n = 3), or facial palsy due to complex craniofacial fracture (n = 3). Nine patients required revision to achieve optimal weight. Fifty-two patients had full eye closure. The remaining 11 patients had almost complete eye closure. CONCLUSIONS: Facial paralysis is devastating for the patient and immediate facial reanimation should be performed. We have demonstrated that gold weight implantation and lateral tarsorrhaphy are simple and effective in achieving eye closure.
