Tuberculous gumma
Tuberculous gumma
Tuberculous gumma (pronunciation: tu-ber-kyu-lous gum-ma) is a rare form of cutaneous tuberculosis that is also known as metastatic tuberculous abscess or ulcer.
Etymology
The term "tuberculous" is derived from the Latin word "tuberculum" which means a small swelling, and "gumma" is derived from the Latin word "gummi" which means a gum-like mass.
Definition
Tuberculous gumma is a form of cutaneous tuberculosis that is characterized by the formation of a painless, firm, and subcutaneous nodule that eventually ulcerates and discharges a purulent material. It is a result of hematogenous spread of Mycobacterium tuberculosis from a primary focus, often in a person with a high degree of tuberculin sensitivity.
Symptoms
The primary symptom of tuberculous gumma is the presence of a painless, firm, subcutaneous nodule that eventually ulcerates and discharges a purulent material. Other symptoms may include fever, weight loss, and night sweats.
Diagnosis
Diagnosis of tuberculous gumma is often made through a combination of clinical examination, histopathology, and bacteriology. A skin biopsy may be performed to confirm the diagnosis.
Treatment
Treatment for tuberculous gumma typically involves a combination of antituberculous therapy and surgical debridement of the lesion.
