Which of the following is seen in primary T.B?
Primary Tuberculosis The infection of an individual who has not been previously infected or immunized is called primary tuberculosis or Ghon's complex or childhood tuberculosis. Primary complex or Ghon's complex is the lesion produced in the tissue of poal of entry with foci in the draining lymphatic vessels and lymph nodes. The most commonly involved tissues for the primary complex are lungs and hilar lymph nodes. Other tissues which may show primary complex are tonsils and cervical lymph nodes, and in the case of ingested bacilli, the lesions may be found in the small intestine and mesenteric lymph nodes. The incidence of a disseminated form of progressive primary tuberculosis is paicularly high in immunocompromised host e.g. in patients of AIDS. Primary complex or Ghon's complex in lungs consists of 3 components: pulmonary component lymphatic vessel component lymph node component Ref: Textbook of pathology (Harsh Mohan)6th edition, page no.153
