Aetiology and Pathogenesis Tungiasis is a localized skin disease commonly affecting one foot and caused by the burrowing flea Tunga penetrans (see also Chapter 60). This is also known as sandflea, jiggers or chigoe infestation. It has been found in Central and South America, the West Indies, Africa, Madagascar, India and Pakistan Sand flea that burrows into human skin and skin of mammals, causing the disease tungiasis Parasite is common in tropical locations (South America, Caribbean, Africa, Pakistan, west coast of India) Single flea bite causes local discomfort Multiple bites cause debilitation and secondary infections (tetanus, gas gangrene Tungiasis is an inflammatory skin disease caused by infection with the female ectoparasitic Tunga penetrans (also known as chigoe flea, jigger, nigua or sand flea; NOTE: not chigger), found in the tropical parts of Africa, the Caribbean, Central and South America, and India. Tunga penetrans is the smallest known flea, measuring 1 mm across

Tungiasis is a cutaneous infestation caused by the burrowing flea, Tunga penetrans. This infection typically results in the development of one or more wart-like fibrous papulonodules. The causative flea is endogenous to Central and South America, sub-Sarahan Africa and portions of India; consequently, tungiasis is rarely reported in North America Tunga penetrans is an invasive flea that lodges itself in the epidermis of mammals, producing a painful nodular lesion known as tungiasis

Lingual tungiasis is a rare diagnosis that was made on histological examination. Atypical presentation outside an endemic area predisposed the patient to partial glossectomy instead of the less invasive flea enucleation Microscopic (histologic) description. Composed primarily of dense, compact bone and broad trabeculae of mature bone within paucicellular fibrous stroma. Outer surface is sharply demarcated and lined by respiratory epithelium in sinus tumors. Areas resembling osteoblastoma (narrow, anastomosing trabeculae of woven bone with osteoblastic rimming. Tungiasis (sand flea disease) is an ectoparasitic skin disease caused by the female sand flea/jigger flea (Tunga penetrans).

  1. Author summary Tungiasis (also called sand flea disease) is a neglected tropical disease (NTD) caused by the penetration of female sand fleas in the skin, typically at the toes, the sole or the heel. Once embedded in the upper strata of the skin, the parasite hypertrophies, enlarging its body size by a factor of 2000 within ten days. This causes intense inflammation with pain and itching.
  2. Tunga penetrans. Tunga penetrans (also known as chigoe flea, jigger, nigua, chica, pico, cique, or suthi) burrows under the skin of humans, unlike other fleas which are ectoparasitic on the surface of the skin. The females remain embedded in the host tissue during engorgement and egg-production. The fleas are usually found between the toes or.
