Background/Aims: Primary anorectal melanoma is a very rare malignant tumor
with no more than 300 cases reported in the literature. Methods: Two cases
of anorectal melanoma are reported herein. Results: Both patients, aged 44
and 74 years, presented at the outpatient department with anal bleeding, on
e after being treated far 3 months with antihemorrhoidal drugs. The diagnos
is was established with proctoscopy and biopsy, and a palliative abdominope
rineal resection in the presence of lymph node metastases was performed fol
lowed by chemotherapy with vindesine. Although the procedures were not cura
tive, both patients had an uneventful postoperative recovery, and lived 4 y
ears and 21 months, respectively, without bleeding problems albeit with the
inconvenience of a colostomy. Conclusions: For the time being there is no
convincing proof of the value of either types of proposed surgical manageme
nt. We agree with those who believe that abdominal perineal resection has a
n advantage regarding the prognosis and quality of life. Copyright (C) 2000
