Elephantiasis mimicry in recurrent lower limb skin infections in a diabetic patient: a case report

Chronic edema as a complication of systemic diseases or infections can mimic filarial lymphedema (also known as elephantiasis) and considered so. We describe a case of chronic lymphedema that mimicked elephantiasis in a diabetic man.

The patient was a 70-year-old black man, bed-bound at the time of admission following a diagnosis of stroke and hypertension in the previous 5 years. He had been diabetic for 20 years with poorly controlled diabetes mellitus. He suffered recurrent bilateral lower limb skin infections for 5 years prior to admission that culminated into progressive lowerlimb edema. The infections eventually complicated into skin edema, hardening, fissuring, and hyperkeratotic plaques. The physical examination revealed Tinea pedis and bilateral non-pitting edema of lowerlimbs to the level of the knees. Investigations confirmed non-filarial lymphedema-related skin changes. The absence of the classic pebbly/cobblestone skin changes ruled out elephantiasis nostra verrucosa (ENV), with a possibility of it being in the early stages of evolution. The patient's skin fissuring and infections were successfully treated with antibiotics and antifungals while compression stockings helped to relieve the edema.

Chronic lymphedema can complicate repeated non-filarial infections of lower limbs. Its fissures are a risk factor for cellulitis, prompting early identification and management of both infections and lymphedema to halt their vicious cycle, especially in at risk populations like diabetics.
