Oral pyogenic granuloma: An 18-year retrospective clinicopathological and immunohistochemical study

Pyogenic Granuloma Diagnosis and Management: A Practical Review

Background

Pyogenic granuloma (PG), or lobular capillary hemangioma, poses a clinical challenge with its uncertain etiology and treatment options. Although the clinical features and prevalence of PGs are well established, definitive evidence-based treatments remain elusive. This practical review aims to illuminate the complexities of PG management by analyzing surgical interventions based on literature analysis.

Methods

A PubMed/Medline search of "pyogenic granuloma" and "surgery" yielded 1171 studies. Inclusion criteria targeted intervention-associated PG complications over 5% and treatment modalities, excluding nonclinical studies and topics unrelated to plastic and reconstructive surgery. Screening involved Oxford level of evidence, patient data extraction, complications, intervention types, success rates, sessions, follow-ups, and treatments.

Results

Thirty-one studies met inclusion criteria. Most studies were retrospective (67.7%). Ten studies satisfied intervention-linked eruptions, primarily oculoplastic, whereas 21 investigated both surgical and nonsurgical treatment modalities. Across interventions, 3579 patients (age: 34.2-85.7 years) were involved. Postsurgical PG complications averaged 15.1% and were treated predominantly with surgical excision, achieving nearly complete resolution. Surgical and nonsurgical treatment studies included 1233 patients (age: 3-46.5 years), demonstrating a 68.2% average resolution after a single session, with surgical excision exhibiting the highest success rate (96.2%) and minimal complications.

Conclusions

This practical review highlights the complexities of managing PG, emphasizing a spectrum of effective treatments and potential postoperative complications. Ophthalmologic procedures showed PG incidences of 9%-24.4%. Surgical excision proved highly effective, surpassing methods like lasers and injectables that exhibited varied success rates requiring multiple treatment sessions. Challenges included study diversity and varying evidence levels, warranting further comparative research for PG management strategies.

Diagnosis and management of exuberant palatal pyogenic granuloma in a systemically compromised patient - Case report

AIM

To discuss the diagnosis and treatment of an exuberant oral pyogenic granuloma (OPG) in the palatal region in a systemically compromised patient.

METHODS AND RESULTS

A 50-year-old woman presented with extensive and painless nodular mass that extended throughout the palatal region, with difficulty speaking, swallowing and spontaneous bleeding for 6 months. Her medical history showed poorly controlled type II diabetes mellitus and hypertension. The intraoral physical examination also revealed poor oral hygiene and periodontal disease. After clinical and radiographic evaluation, the presumptive diagnosis of OPG was made and complete excision of the lesion was performed. Local hemostatic measures were employed to control bleeding. Microscopic evaluation showed a lobulated lesion composed of many blood capillaries confirming the diagnostic hypothesis.

CONCLUSIONS

In summary, individuals with severe periodontal disease and systemic disorders may present exacerbated clinical presentations of OPG.

23-Year-old male with multiple giant facial pyogenic granulomas being treated with combined topical timolol and steroid: A case report

Introduction and importance

Pyogenic Granuloma (PG) commonly presents as a solitary, erythematous, non-tender, skin lesion, usually not exceeding 2.5 cm. Although Surgical excision is the first-line treatment, conservative treatments are recently developing. Solitary PG is well documented unlike multiple PGs, as the latter is rarely described in terms of its presentations and treatments.

Case presentation

This interesting case report describes a 23-year-old male who developed multiple PGs on the nasal area (2cmx2cm) and mandibular area (10cmx2cm) after sutures removal secondary to a recent history of trauma. The lesions regressed after successfully treated with two months of timolol drops and topical corticosteroids. Subsequently, intralesional corticosteroids injections were given once-per-month for two months, with residual fibrosis of the regressed lesion.

Clinical discussion

While the most common site for multiple PGs is the interscapular region, this case reports giant, facial, multiple PGs followed suture removal. Although β-blockers were reported to successfully treat solitary PG, only a few cases were raised to discuss this treatment in terms of multiple PGs. This case completes the series and reports successfully-treated multiple PGs using a combination of topical timolol and steroid.

Conclusion

This case supports the need to consider multiple PGs as a differential diagnosis following sutures removal even when it reaches rarely reported diameters. Also, it suggests topical timolol and steroids as an effective conservative treatment in similar cases of multiple giant PGs. Notably, the treatment failed to sidestep scar formation.

•

This report acts as a proof of the efficacy of topical timolol and steroid as a conservative treatment for multiple Pyogenic Granulomas, even when the lesions reach a large diameter.

•

It is noteworthy that this treatment failed to sidestep scar formation.

•

This case supports the need to consider Pyogenic Granulomas a differential diagnosis after sutures removal.

•

This case highlights the fact that multiple Pyogenic Granulomas can reach diameters larger than 2 cm.

Large Lobular Capillary Hemangioma Associated with Ingrown Toenail: Histopathological Features and Case Report

Lobular capillary hemangioma (LCH-PG) is a type of pyogenic granuloma characterized by proliferating blood vessels that resemble conventional granulation tissue. Granulation tissue is very often seen in association with ingrown toenails. Despite the close relationship between both entities, LCH-PG shows clinically different behaviors, such as rapid growth and frequent recurrence. Currently, it is unknown exactly how the different etiological factors contribute to the formation of differences between entities. We present a case of a large LCH-PG associated with chronic onychocryptosis in a 26-year-old man. Histopathological features included extensive signs of ulceration, hyperkeratosis, and patchy epidermal acanthosis with the presence of fibrous septa with lobular areas beneath the ulcerative area. The presence of stroma with a marked proliferation of blood vessels with wall thickening and mixed-type inflammatory changes was also characteristic. In advanced stages of onychocryptosis, as presented here, conventional granulation tissue or pyogenic granuloma can be clinically difficult to distinguish from other benign or malignant neoplasms. Histological examination is mandatory, and excisional biopsy can provide a definitive diagnosis.
