Description
Abstract
Mohs micrographic surgery is a microscopically
controlled method of skin cancer excision which minimises
recurrence rates and maximises conservation of surrounding
normal tissue. Micrographic surgery using horizontal frozen
sections has achieved wide acceptance as the optimal treatment
for those basal cell carcinomas and squamous cell carcinomas
that fulfil particular characteristics. These include recurrent
or incompletely excised tumours, those on particular areas
of the face and those with clinical and histological features
associated with a higher probability of incomplete excision
if conventional methods are used.
Mohs surgery using either frozen sections (with or without
immunohistochemistry) or horizontal paraffin-embedded sections,
has also been adapted to the excision of skin tumours including
certain squamous cell carcinomas, dermatofibrosarcoma protuberans
and lentigo maligna.
