Ghon's complex
Ghon's complex (pronounced: /ɡɒnz ˈkɒmplɛks/) is a medical term referring to a primary tuberculosis infection. It is named after the Austrian pathologist Anton Ghon (1866–1936).
Etymology
The term "Ghon's complex" is derived from the name of Anton Ghon, who first described the lesion in 1916. The word "complex" in this context refers to a group of related, often intricate and interrelated, features.
Definition
Ghon's complex is a lesion seen in the lung that is caused by tuberculosis. The complex is composed of a small, peripheral lung nodule (Ghon focus or Ghon's lesion) and the corresponding lymph nodes draining that region of the lung (hilar nodes). The Ghon focus is usually subpleural, often in the mid to lower zones of the lung.

- Ranke complex: A term sometimes used interchangeably with Ghon's complex, although it technically refers to a Ghon's complex that has become calcified and fibrotic, often seen in latent or healed tuberculosis.
