A Research of Pyogenic Granuloma Genesis Factor With Immunohistochemical Analysis:

Comparison of the efficacy and adverse effects of long pulsed 1064 nm Nd: YAG laser and sclerotherapy in the treatment of pyogenic granuloma in children: a retrospective study

Pyogenic granuloma (PG) is benign vascular lesions of the skin and mucous membranes that often involve the skin and mucous membranes, which often trouble patients due to its frequent bleeding. The traditional treatment is surgical removal, but its bleeding, pain, and trauma have led doctors to look for more minimally invasive methods. Between June 1, 2022 to March 1, 2024, we retrospectively analyzed 72 children with PG who were seen and treated in our department for long pulsed 1064 nm Nd: YAG laser (Gentle Nd: YAG laser) and sclerotherapy, respectively. The efficacy of the two treatments, pain scores, duration of surgery, and adverse events were assessed. The results showed no significant difference between the two groups in the efficacy of first treatment and the efficacy of secondary treatment. Although the procedure time was shorter in Gentle Nd: YAG laser group than in sclerotherapy group, the pain was more pronounced and the incidence of scarring was higher. No significant recurrence was detected in either group during the 6-month follow-up period. Gentle Nd: YAG laser and sclerotherapy for PG are sensitive, less invasive, and safe treatments. Sclerotherapy may be more acceptable to patients than Gentle Nd: YAG laser therapy because it is less painful and scarring is rare.

An alternative method for esthetic and functional management of oral pyogenic granuloma

BACKGROUND

Pyogenic granulomas (PGs) are gingival enlargements which cause esthetic and functional problems that hinder chewing and maintaining oral hygiene. In this series consisting of six cases, we report the rehabilitation of PG using partly de-epithelialized gingival grafts.

METHODS

Following documentation of clinical measurements, a concurrent treatment plan of excision and reconstruction with partly de-epithelialized gingival grafts were followed for all the cases. Six months following procedures, clinical parameters were measured again and a short patient-reported outcome measures consisting of three questions were applied.

RESULTS

In histological evaluations, PG features were observed. In the fourth postoperative week, interdental papilla and attached gingiva were restored. Six months follow-up showed reduction in plaque and gingival indices, clinical attachment loss, and mobility. Mean keratinized tissue height was increased from 2.58 ± 2.20 to 6.66 ± 1.66 in the 6th month of operation. Oldest case was stable after 12 months of follow-up and no infection was found at grafting sites. Papillary coverage was achieved.

CONCLUSION

If the PG is not completely removed due to esthetic reservations, a recurrence may occur. Within our limitations, we can suggest that the immediate esthetic rehabilitation with partly de-epithelialized gingival graft presents a compatible approach in the treatment of mucogingival defects after aggressive excision of PG.

Comparison of the Efficacy of Combined Silver Nitrate Coagulation and Shave Excision With Surgical Excision and Linear Closure in the Treatment of Pyogenic Granuloma

BACKGROUND

Pyogenic granuloma (PG) is a common benign vascular neoplasia. Optimal treatment should have an aesthetically pleasant scar and a low recurrence rate. No treatment method that is fully effective in solving these has been demonstrated. Silver nitrate cauterization is another method for the management of PG lesions.

OBJECTIVE

The effects of silver nitrate on the treatment of PG have not been sufficiently investigated and should be investigated with objective data and a controlled study.

METHODS

The prospective clinical trial was designed to compare silver nitrate cauterization with surgical excision treatment. Procedure times and procedure costs, comfort and satisfaction scales, recurrences, the Patient and Observer Scar Assessment Score, and the Vancouver Scar Scale were compared to evaluate treatments.

RESULTS

Silver nitrate treatment had lower procedure times, costs, and better satisfaction and comfort scale scores. The scar assessment scores were better for the silver nitrate treatment. The patients in both groups were successfully treated and no recurrence was seen.

CONCLUSION

Silver nitrate cauterization is low-cost, fast, safe, reliable, and effective with good aesthetic results for the treatment of PG lesions. This study shows that silver nitrate cauterization is a good alternative to surgical excision in the management of PG.

A giant pyogenic granuloma gravidarum in the nasal cavity: A case report

Pyogenic granuloma (PG) is a benign fibrovascular proliferative lesion on the skin and mucous membranes, but its pathogenesis remains unclear. PG usually occurs on the head and neck region, fingers and toes. The oral gingiva is the most common location for pregnant patients, while it is rarely found in the nasal cavity. This case is notable not only for its uncommon site and size but also for its gradual growth after delivery. Endoscopic surgery can achieve the desired cosmetic effect and a satisfactory airway. A rapidly growing hemorrhagic lesion in the nasal cavity should be considered as a differential diagnosis.

Gingival and Alveolar Ridge Overgrowths: A Histopathological Evaluation from Saudi Arabia

Background

Focal tissue overgrowths on the gingiva and edentulous alveolar ridge are occasionally perplexing to periodontists, owing to the wide variety of differential diagnoses that may be responsible. As such, biopsy and microscopy are often required to establish a definitive diagnosis. The present study aimed to retrospectively evaluate focal gingival and alveolar ridge overgrowths at a single institution in Saudi Arabia.

Materials and Methods

Histopathology reports and slides from patients presenting to King Saud University Hospital between 1984 and 2016, particularly those with focal gingival enlargements other than those due to gingivitis and periodontitis, were collected and analyzed based on age, sex, and location.

Results

A total of 624 patient records were evaluated, with a mean age of 35 years (range, 1 week–91 years), peak incidence in the third decade of life, male-to-female ratio of 1:1.4, and a slightly higher prevalence of lesions in the mandible. The majority (88%) of the lesions were reactive or hyperplastic, followed by malignant (10%) and benign (2%) tumors. A total of 24 distinct histological entities were diagnosed across the three groups. The most common histologically diagnosed lesions were pyogenic granulomas (38%), fibromas (33%), peripheral ossifying fibromas (9%), squamous cell carcinomas (7%), peripheral giant cell granulomas (6%), neurofibromas (1%), and non-Hodgkin lymphomas (1%).

Conclusion

Similar to what has been reported by most previous studies, reactive hyperplastic lesions were the most prevalent focal overgrowths found in the gingival and alveolar mucosae. Carcinomas at these sites, however, may be an understated but significant clinical and epidemiological problem in Saudi Arabia. Gingival and alveolar ridge lumps can serve as a nexus for cooperation between periodontologists and oral pathologists to improve diagnosis, disease classification, and patient management.

Topical corticosteroids for noninvasive treatment of pyogenic granulomas

Pyogenic granulomas are benign vascular proliferations of the skin and mucous membranes that tend to bleed easily. They typically require procedural treatments that can be difficult for patients with intellectual disabilities or behavioral concerns to tolerate. In our practice, we have found the use of topical clobetasol to be effective to induce regression of cutaneous pyogenic granulomas. We present here a case of an adolescent patient with autism and two bleeding pyogenic granulomas who poorly tolerated a biopsy of the first lesion and could not tolerate subsequent procedures. Topical therapy with clobetasol effectively managed the second pyogenic granuloma, an approach representative of a noninvasive practice utilized in our clinic.

Gingival Fibroma: An Emerging Distinct Gingival Lesion with Well-Defined Histopathology

Gingival growths, barring a few are mostly reactive and seldom exhibit significant true neoplastic potential. The common etiology is local irritation from dental plaque/calculus, trauma as well as medication-related overgrowth. Such lesions are easily distinguishable and categorized into diagnoses such as pyogenic granuloma, peripheral ossifying fibroma, etc. We present a previously undescribed, but commonly encountered, reactive gingival growth with unique histologic features and suggest the diagnostic term "gingival fibroma." An IRB approved retrospective review of the University of Florida Oral Pathology Biopsy Service encompassing years 2010-2019, was performed to select cases. Demographics, clinical data, and microscopic diagnoses were recorded and analyzed. Four board-certified oral and maxillofacial pathologists agreed upon and established the diagnostic criteria. These are: a prominent fibromyxoid stroma, variable cellularity, a whorled or storiform pattern of arrangement of the cellular elements, lack of significant inflammation or vascularity, and complete absence of calcification, and/or odontogenic islands. A total of 60 cases met all criteria and were included in the study. Age range in years was 14-87 with the mean at 45.11 years. A striking female predilection (90%) was noted. Approximately 62% of cases were reported on the maxillary gingiva, followed by 38.3% in the mandibular gingiva. Majority, 66.7% were in the anterior incisor region followed by 11.7% in the canine/first premolar areas. All lesions were submitted as excisional biopsy, and 4 cases recurred within 2-3 years of excision. In all cases, lesional tissue appeared to extend to the surgical base of the specimen. We present 60 cases of a histologically unique entity occurring exclusively on the gingiva and introduce the diagnostic term "Gingival Fibroma" for these lesions. Further studies with adequate clinical follow-up may help understand the exact clinical behavior of these lesions.

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

BACKGROUND

Pyogenic granuloma (PG) is a lesion characterized by the proliferation of blood vessels, commonly affecting the skin and the mouth. We aimed to compare clinical, microscopic, and immunohistochemical features of the two types of oral PG: lobular capillary hemangioma (LCH) and non-LCH (NLCH).

METHODS

Epidemiological and clinical data from 2000 to 2018 were collected from the archives of our institution, and histopathological sections of PG were reviewed. Immunohistochemical analyses (CD34, D2-40, SMA, mast cell, and Ki-67) were performed in 34 cases.

RESULTS

Sixty-two LCH and 107 non-LCH samples were included. The mean (±SD) age of the patients was 38.59 ± 16.96 years; 55.62% were female; 39.64% of cases occurred in the gingiva, 44% of the nodules were pedunculated, and 13.02% of patients reported a history of trauma. NLCH was more prevalent among older patients than LCH. The most prevalent site of LCH was the lips, while NLCH occurred more in the gingiva (P < 0.05). Epithelial atrophy, microvessels, SMA-positive areas, and Ki-67-positive nuclei were more prevalent in LCH (P < 0.05).

CONCLUSIONS

PG accounted for 2.25% of lesions archived in the pathology service and most cases were NLCH. LCH and NLCH exhibited clinicopathological differences in terms of age, site, epithelial atrophy, vascularization, and proliferation rate.

Pyogenic granuloma after cosmetic eye whitening

CLINICAL CASE

A 46-year-old caucasian male with a history of chronic conjunctival hyperemia, presented at our clinic 5 years after he underwent the surgical procedure of cosmetic eye whitening. On examination we observed pyogenic granuloma in the right eye; besides acute nongranulomatous anterior uveitis and necrotizing scleritis in both eyes.

RESULT

Complete clinical evaluation and full work-up exclusion of systemic diseases was done. The pyogenic granuloma was treated with surgical resection, as well as anterior uveitis and necrotizing scleritis were successfully treated with systemic corticoesteroids and methotrexate.

CONCLUSION

The surgical cosmetic eye whitening could have as complication the pyogenic granuloma in addition to necrotizing scleritis and nongranulomatous anterior uveitis; and be present 5 years after the procedure. The surgical resection is a successful treatment for this presentation of pyogenic granuloma.

A capillary hemangioma of lobular subtype (pyogenic granuloma) in the calvarium of a pregnant woman

A lobular capillary hemangioma, previously known as a pyogenic granuloma, is a benign vascular lesion of the skin or mucous membrane. We report a case of capillary hemangioma of lobular subtype in the calvarium of a 28-year-old pregnant woman which presented as a sore and rapidly growing bulge over the left fronto-parietal region. Magnetic resonance imaging of the brain and skull showed an expansive tumor with brain displacement, skull erosion, and scalp infiltration. The tumor was surgically removed, and histopathological examination showed a capillary hemangioma of lobular subtype. To the best of our knowledge, this is the first report of a lobular capillary hemangioma in the calvarium, and it represents a rarity to be considered among the many other differential diagnoses for neurosurgical lesions involving the skull, especially in pregnant women.
