    Notes:
    Cutaneous melanoma is rare among Chinese people. The clinicopathologic features and prognostic factors of 63 Hong Kong ethnic Chinese cases were analysed. We found that the mean age of onset was 65.5 years with a female : male ratio of 1 : 1.33. Forty-two (66.7%) patients had their tumours on their feet. More than 50% had the acral lentiginous histologic subtype. The mean tumour thickness was 5.73 mm with 92.1% (n = 58) having a Clark's level of III or more. Of the tumours, 57.1% were ulcerated. Stage I and II tumours comprised 73% (n = 46) while stage III and IV tumours made up of 26% (n = 17). The 1-, 3- and 5-year survival rates were 75%, 30% and 17%, respectively. Univariate analysis for overall survival showed that advanced clinical staging (stage III and IV), tumour ulceration and thicker tumour (〉4 mm) had a significantly poorer prognosis. Multivariate analysis demonstrated that advanced clinical staging was the most decisive prognostic factor followed by tumour ulceration. Our study showed that cutaneous melanoma in Chinese people is a disease predominantly of an older age group with the acral lentiginous histologic type located mainly on the feet. The prognosis depends on clinical staging and ulceration status.

    Summary Six patients with extramammary Paget's disease were treated with curative intent radiotherapy. Two of the patients had associated underlying adenocarcinoma. Radiotherapy was given as primary treatment (two patients), definitive treatment for postexcisional relapse (three patients) and adjuvant treatment (one patient). Radiotherapy techniques included high dose rate mould brachytherapy, electron beam, superficial X-ray and photon treatments. Follow-up durations after radiotherapy were 1.2–14.8 years. Complete response was obtained in five patients while one patient had a partial response. Marginal failure occurred in one complete-responder who was successfully salvaged by surgery. The two patients with underlying adenocarcinoma died of distant metastasis. Radiotherapy side effects were acute confluent wet desquamation and mild late skin atrophy. Our results confirmed the useful role of radiotherapy in the management of extramammary Paget's disease.

    Notes:
    Nasopharyngeal carcinoma (NPC) is a common malignancy among southern Chinese. The tumours are mostly undifferentiated carcinomas and are associated with Epstein–Barr virus. Patients present with a blood-stained postnasal discharge, impaired hearing, tinnitus or cervical lymph node enlargement. Radiotherapy with or without chemotherapy is the standard treatment. Though metastatic lung, bone or liver disease is not uncommon on relapse, skin metastasis is rarely reported. The small number of reports in the literature are either brief or have only a few patients. In this report, we describe our series of four Hong Kong Chinese patients with NPC who had distant cutaneous metastases.
