O ovom radu je opisan slučaj aktinomikotičnog granuloma kod visoko gravidne krmače, koja je hirurški tretirana. Krmača rase Landras, stara oko 3 godine i telesne mase oko 200 kg, je vlasništvo jedne privatne farme u istočnoj Srbiji. Krmača je normalno jela i manifestovala normalno ponašanje. Kod prvog pregleda, tumor je bio veličine pesnice, a kod drugog, 81 dan posle parenja, tumor je bio veličine 5 litara. Pregledom je dijagnostikovana purulentna granulomatozno-aktinomikotična inflamacija mlečne žlezde. Ova dijagnoza je potvrđena histopatološkim pregledom. Ovaj slučaj pokazuje da je moguće uspešno odstraniti mamarni tumor krmače u kasnoj gravidnosti.
