I agree

granulomatous inflammation. Being a tender, axillary lesion with discharging sinus the probability of hidradenitis suppurativa may be considered

Valuable opinion

Mixed inflammatory exudate with predominant neutrophils with macrophages, multinucleate giant cells. s/o chronic relapsing suppurative inflammation. Negative for malignancy. Favors Hidradenitis suppurativa

?Hidradenitis suppurativa

Thank you doctor
