Effective Management of a Pregnancy Tumor Using a Soft Tissue Diode Laser: A Case Report and Literature Review.

Introduction

Pregnancy tumors, also known as pyogenic granulomas or granuloma gravidarum, are benign vascular lesions commonly seen in the oral cavity of pregnant women. Though non-cancerous, they tend to grow rapidly, causing bleeding, pain, aesthetic concerns, and functional interference. Their development is linked to hormonal changes during pregnancy and local irritants like plaque or trauma. Traditional surgical removal can lead to discomfort and significant bleeding. This study aims to demonstrate a successful, minimally invasive management of a pregnancy tumor using a soft tissue diode laser, supported by a literature review highlighting this modality's benefits.

Methods

This report presents a case involving a 27-year-old pregnant woman in her second trimester with a growing gingival lesion on the labial gingiva near the left maxillary premolars. Clinical assessment identified it as a pregnancy tumor. The lesion was excised using a 980 nm diode laser (Dr. Smile, Wiser) in continuous wave (CW) mode with a 400 μm initiated fiber, under local anesthesia. Due to effective haemostasis, sutures were unnecessary. The excised tissue was sent for histopathological analysis to confirm the diagnosis.

Results

Laser excision was performed without intraoperative bleeding or suturing. Postoperatively, the patient experienced minimal discomfort, and healing was rapid with complete tissue regeneration by the third week. Histopathology confirmed pyogenic granuloma. The laser facilitated excellent bleeding control, minimized trauma, and enhanced patient comfort.

Conclusion

Diode laser excision is a safe, effective, and minimally invasive treatment for pregnancy tumors. It offers significant advantages-reduced bleeding, less postoperative pain, faster healing, and higher patient satisfaction-over conventional surgical methods. The literature from 2000 to 2025 supports the reliability of diode lasers in managing oral soft tissue lesions during pregnancy.
