What's your diagnosis of this case?
Hint : It's a section of Lymph Node from an AIDS patient.
Yea mycorbacterium avium makes a lot more sense
Mycobacterium in lymph node...A.I.D.S
Acid fast bacilli within histiocytes - in a lymph node from AIDS patient; tuberculous or non-tuberculous mycobacteria (MAC).
this is a Ziehl-Neelsen stain, there are Langhans' cells and the patient has AIDS--> I agree with the "mycobacteria-hypothesis", most probably MAC (opportunistic pathogens)
Answer : Mycobacterium Avium Intracellulare Complex.
Acid Fast Bacilli are seen within Histiocytes ( Ziehl Neelsen Stain is used ).
Separate names with a comma.
