Tuberculosis mnemonics

Hello!
Today's post is all about TB! :D
So many names to remember :/
Rich focus
Definition: A Rich focus is a tuberculous granuloma occurring on the cortex of the brain that ruptures into the subarachnoid space, causing tuberculous meningitis. (A dormant intracranial subpial focus is also  known as Rich focus)
Mnemonic: Brainy people are Rich.

Simon focus
Definition: A Simon focus is a tuberculosis (TB) nodule that can form in the apex of the lung when a primary TB infection elsewhere in the body spreads to the lung apex via thebloodstream.
Mnemonic:  *I apologize for my language* Simon has Sex at Apex

Assman focus
Definition: Assman focus is chronic infraclavicular lesion of pulmonary tuberculosis. It is a deep apical lesion.
Mnemonic: *Sorry for the vulgar mnemonic again* Ass (anal) sex at Apex :D 

Weigerts focus
Definition: Lymphohematogenous dissemination may lead to miliary tuberculosis when caseous material reaches the bloodstream from a primary focus or a caseating metastatic focus in the wall of a pulmonary vein (Weigert focus - Subintimal focus in pulmonary vien).

Phlyctenular Keratoconjunctivitis - Nodular inflammation of the cornea or conjunctiva that results from a hypersensitivity reaction to tuberculin protein
Scrofuloderma - Skin lesions result from direct extension of underlying TB infection

That's all!

I'm not sure if all of these are accurate, because I collected all of this information from the internet. Let me know if it is wrong in the comments, I'll correct it!
