    ABSTRACT: BACKGROUND: Nail apparatus melanoma (NAM) is a rare melanocytic neoplasm with pejorative prognosis often related to late diagnosis. Early diagnosis at in situ stage (NAMis) is difficult, but essential to improve prognosis. NAMis management is not well established yet. Removal of the whole nail unit has been advocated in several small series as a potential treatment for NAMis. OBJECTIVE: To report and assess 'functional' or 'conservative' surgery for NAMis and evaluate its long-term oncologic safety. METHODS: Retrospective study of cases diagnosed in the University Hospital Saint-Pierre collected over a 13 year period and compared with the published data. RESULTS: Eleven cases of NAMis were identified: 73% concerned females. Thumb and first toe were the most affected digits (63% of total). Monodactylic longitudinal melanonychia (LM) was the most frequent presentation (92%). Mean diagnosis delay was 5 years. Diagnosis was suspected on the basis of clinical and dermatoscopic signs and was confirmed by pathological examination. All patients underwent complete nail unit removal with 6 mm security margins around the anatomic boundaries of the nail. Two late local recurrences were observed at 7 and 11 years follow-up. CONCLUSIONS: Our series, the largest up to now, demonstrates that 'functional surgery' is a rational approach for NAMis with an excellent oncologic safety at 5 years. However, this study suggests that a very long-term follow-up is mandatory, as recurrences may appear late.

    ABSTRACT: Since its first use 40 years ago, 5-fluorouracil (5-FU) has become an unquestionable component of colorectal cancer treatment. It is also now well established that infusional 5-FU administration, in combination with leucovorin, is associated with better tolerance and at least equal efficacy than bolus administration. However, requiring catheter and infusion pumps, infusional 5-FU administration is costly, rather inconvenient for patients and potentially associated with morbidity, initiating subsequent oral chemotherapy development. To address intravenous 5-FU related issues, oral fluoropyrimidines have been developed such as capecitabine, preferentially converted to 5-FU into tumour cells, and UFT, able of bypassing intestinal dihydropyrimidine dehydrogenase. We discuss in this article current oral fluoropyrimidines achievements in colorectal cancer management.

    ABSTRACT: Cutaneous Paget's disease (PD) is a rare entity, predominantly involving the breasts. Anal involvement is rather exceptional, and can be associated with underlying malignancies, among which prostate and rectal adenocarcinoma. We report the case of a 71-year-old man suffering from a long history of anal itching, associated with an erythematosquamous lesion of the right buttock extending up to the anus. The diagnosis of perianal PD (PAPD) was confirmed by histopathological demonstration of Paget's cells from a biopsy performed after ineffective topical treatment. Radiological and further clinical inspections allowed us to exclude any synchronous malignancy. A first-step surgery consisted in coelioscopic diverting sigmoid colostomy, along with multiple perianal, anal and rectal biopsies revealing an anal canal involvement. Coelioscopic abdominoperineal surgery and a wide cutaneous excision were then performed. Histopathological analysis revealed positive posterior margin, requiring further excision. No adjuvant therapy was prescribed, and to this day, after a one-year and a half follow-up, the patient remains disease-free. Our case report and review of PAPD stress that appropriate management is required to improve the poor prognosis of this rare affection.
