Elephantiasis nostras verrucosa in a patient with systemic sclerosis.
Elephantiasis nostras verrucosa (ENV) is an unusual skin condition characterized by dermal fibrosis and hyperkeratotic verrucous lesions resulting from chronic nonfilarial lymphoedema. The condition is similar to 'elephantiasis tropica', in which elephantiasis develops secondary to filariasis. Lymphatic obstruction can be primary or due to various causes such as surgery, tumour, radiation, congestive heart failure or obesity. Recurrent attacks of cellulitis lead to further impairment of lymphatic drainage, causing permanent swelling, dermal fibrosis and epidermal thickening. We report a case of a 56-year-old man with systemic sclerosis (SS), who presented with painful lesions on both legs, consistent with ENV. He developed extensive, fungating, papillomatous lesions on the skin of the legs, toes and dorsa of the feet over a period of 3 years. Histology revealed dense dermal fibrosis, oedema of the papillary dermis and extensive pseudo-epitheliomatous changes. To our knowledge, this is the first report of ENV in which SS was considered to be the primary cause for the impairment of lymphatic flow.
