“…The differential diagnosis of HIV-associated GA includes a variety of infections, granulomatous lymphoproliferative processes, granulomatous drug reactions, and lichenoid and granulomatous dermatitis of AIDS (LGDA). Granuloma annulare has been described in association with various infectious stimuli, the spectrum of which encompasses Borrelia species, mycobacteria, fungus, HIV, EBV, and hepatitis C, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][28][29][30][31] and hence, it is difficult to exclude that the granulomatous response is related to microbial pathogens other than HIV. Syphilis, mycobacteria, and fungal infection appear unlikely causes of HIV-associated GA. Histological features associated with infection such as tubercles of epithelioid histiocytes, foamy histiocytes, plasma cells, caseation necrosis, and neutrophilic abscesses were absent in all of our biopsy specimens.…”
