In a five-year-period, twenty three cases or peripheral nerve tumours
were seen at the pathology department or Muhimbili Medical Centre. Nin
e of these had von-Recklinghausen's disease (neuroribromatosis). One o
f these patients developed malignant schwannomas at two different site
s simultaneously. Patients with malignant disease in Tanzania as in ot
her sub-Saharan African countries usually get to the large referral ho
spitals late in the course of their disease. Despite this delay and th
e advanced nature of their illness, attempts should be made to achieve
satisfactory palliative results.
