Abstract
Necrotising fasciitis is a rare rapidly progressive, life threatening, soft tissue infection which spreads along fascial planes. We present a patient who was diagnosed with a primary cutaneous Diffuse Large B-Cell Lymphoma (leg type) following initial presentation as probable necrotising fasciitis. Presentation was of a painful swollen leg, septic shock and MRI findings consistent with the clinical signs. Diagnosis of necrotising fasciitis remains challenging and it is often missed in the early stages. Early fascial biopsy and histopathological analysis is useful in cases where the diagnosis is unclear. We feel that this case highlights these important issues and will benefit others in their management of similar cases in the future.

Magnetic Resonanace Imaging (MRI) may be useful as it can differentiate between necrotising fasciitis and cellulites [5]
Summary
Necrotising fasciitis is a rare rapidly progressive, life threatening, soft tissue infection which spreads along fascial planes [1]. If left untreated it is invariably fatal. There has been a 5-fold increase in incidence over the past decade, with increasing age being an important risk factor [2]. It can be caused by group A Streptococcal infection often incombination with Staphlococcus Aureus. Fascial biopsy and histopathological analysis is useful in cases where the diagnosis is unclear. Magnetic Resonanace Imaging (MRI) may be useful as it can differentiate between necrotising fasciitis and cellulites [5]
