In this report, we describe three adult patients diagnosed with lacrimal sac pyogenic granuloma. The presenting symptoms were acute dacryocystitis, lacrimal mass, and bloody tears. The nasolacrimal drainage pathway was obstructed in all cases. Radiologic evaluation performed in one patient revealed the presence of a well-defined mass in the sac with homogenous contrast uptake. Histopathologic examination revealed capillary proliferation and inflammatory cells in a fibromyxoid stroma. The patients were followed up for 11-23 months after external dacryocystorhinostomy without recurrence of the tumor or nasolacrimal obstruction. Pyogenic granuloma may develop from the lacrimal sac mucosa and may cause bloody epiphora. Such a tumor is visualized as a hemorrhagic mass lesion, and it may not have a negative effect on the outcome of DCR.

A case of multiple, eruptive pyogenic granuloma developed on a region of the burned skin: can erythromycin be a treatment option?J Burn Care Res. 2007 Sep-Oct;28(5):754-7.

Pyogenic granuloma (PG) is a common, acquired, benign angiomatous proliferation of the skin and mucous membranes that develops spontaneously or traumatically. PG usually occurs in children and young adults and predominantly located on neck, hands, and extremities. There are numerous theories about the pathogenesis of PG, but the etiology is not clear. Although the occurrence of PG after trauma to the skin is very common, multiple lesions of PG secondary to burn are rare in the literature. In this report, we present a case of multiple, eruptive PG that developed on the burned skin of a 17-month-old boy. After oral erythromycin treatment for 8 weeks, the lesions clearly improved.

Rare case of pyogenic granuloma of the tongue in an 8-week-old infant.Eur Arch Otorhinolaryngol. 2005 Jun;262(6):453-5. Epub 2004 Nov 11.

We present a case of a large pyogenic granuloma of the tongue causing swallowing difficulties in an 8-week-old infant. In the literature, we found no case reports of pyogenic granuloma in such a young infant. It is a quickly growing, hypertrophic inflammatory change consisting of exceptionally richly vascularized granular tissue. The granuloma was located in the central part of the tongue and appeared dark pink in color. It was an easily bleeding pedunculated tumor measuring 3 x 2.5 cm. The etiology of the tumor is unknown; it can arise in sites of previous injury, chronic irritation and infection. The course of the disease is benign and painless, though it can be recurrent. No recurrence was found in the control examination after 3 years.
