Tropical ulcer - Skin Ulcer Treatment and Diet

Synonym: Ulcus phagedenicum tropicum

It occurs in tropical countries, particularly in those with a hot, damp climate. It is often named after the region where it is specifically prevalent e.g., Naga Sore occurring in tbe Naga hills of Assam . Occasionally it takes an epidemic form. It is uncommon in

North India , most probably because of the dry, hot climate. It is by no means an easily communicable disease.

Causes of Tropical ulcer

A run-down condition and diminished vitality of the skin predispose the body to the disease. Soldiers and laborers are affected more often than others. The causative organisms are fusiform bacilli and Vincent's spirochaetes which enter the skin of the feet and legs through abrasions.

Symptoms of Tropical ulcer

The tropical ulcer starts as an abrasion, bite or a wound, on which develops a bulla containing sero-sanguineous material. Rupture of the bulla produces a dirty, stinking slough; destruction of the skin and superficial tissues gives rise to an ulcer which is superficial, 2-5 cm in diameter, and has a granulomatous base. Pain is present.

Diagnosis of Tropical ulcer

The diagnosis is established by the exclusion of other causes of ulceration like cutaneous leishmaniasis, veldt sore, syphilis, pyoderma, tuberculosis etc.

Treatment of Tropical ulcer

1. Course of penicillin or erythromycin (P) or cephalosporin.

2. Clean the part with Condy's fluid or Dettol (P).

.3. Bacitracin dressing twice a day.

4. Improvement of general health.

In resistant cases, the ulcer may have to be excised or curetted and caustics applied.
