Mycosis fungoides: A challenge for the diagnosis

摘要

Mycosis fungoides (MF) is the most common primary cutaneous T-cell lymphoma. This cancer characteristically affects the skin, causing different types of skin lesions that progress slowly through several stages, although not all people with the condition progress through all stages. We present a case of MF in a 32-year-old female patient with many years of nonspecific eczematous and psoriasiform skin lesions and non-diagnostic biopsies. The diagnosis of MF can be very difficult and misleading. The wide range of clinical and pathological presentations of MF makes this disease a challenge for diagnosis and, therefore, requires an accurate differential diagnosis integrated by the patient's clinic together with the histological and immunological findings.
