Histopathologic examination revealed partial ulceration of the respiratory epithelium. The stroma contained numerous vascular channels of variable size, inflammatory cells, and endothelial cells showing no atypia and scanty mitoses (Figure 3 and Figure 4). These findings are similar to those of pyogenic granuloma. Although foamy histiocytes are reported to be a special feature of granuloma gravidarum and are not usually seen in pyogenic granuloma,1 histiocytes were not found in our patient. A diagnosis of pyogenic granuloma associated with pregnancy was made. The patient was followed up until the completion of her pregnancy and did not have any recurrence.
