Epithelioid hemangioma is a benign vascular neoplasm associated with FOS and/or FOSB protein overexpression detected by immunohistochemistry (IHC). The aim of our study was to determine the co-expression or independent IHC expression of FOS and FOSB in a cohort of epithelioid hemangiomas. We also included two cohorts of other vascular lesions: papillary endothelial hyperplasia and lobular capillary hemangioma / pyogenic granuloma. Read More

Soft-tissue lesions in the oral cavity, one of the most common sites for tumors and tumor-like lesions, can be challenging to diagnose and treat due to the wide spectrum from benign indolent to invasive malignant lesions. We report an abnormally large, rapidly growing hyperplastic lesion originating from the buccal mucosa in a 28-year-old male patient. Clinical examination revealed a well-circumscribed, smooth-surfaced, pinkish nodular lesion measuring 2. Read More

A 10-month-old girl presented with a 4-month history of a rapidly growing lesion on the lower lip. Initial assessment and Doppler ultrasound supported a diagnosis of pyogenic granuloma. However, emergent biopsy revealed an embryonal rhabdomyosarcoma, a highly malignant tumor commonly associated with cancer-susceptible syndromes including neurofibromatosis type 1 (NF1). Read More

Lobular capillary hemangiomas (LCHs) are a common form of benign vascular tumors originating from the skin and subcutaneous tissues. We have described the case of a 47-year-old man who had presented with a 1-month history of a tender swelling to the right temporal region. Biopsy was performed to rule out temporal arteritis and demonstrated a subset of LCH, now formally known as intravascular LCH. Read More

Background: Up to now, limited research has been done on a significant number of cases with all types of gingival lesion. Besides, the available literature does not provide reliable data on the epidemiology of gingival lesions, especially non-reactive lesions. Thus, the present study aimed to analyze the frequency and distribution of gingival lesions in an Iranian population. Read More

The use of high-power diode laser technology follows the principles of minimally invasive dentistry. Laser technology is used frequently in pediatric dentistry, especially in surgical procedures, because this approach favors hemostasis, eliminates the use of sutures, improves healing, minimizes treatment time, reduces the sensation of pressure and vibration experienced by the patient, and creates more comfortable postoperative conditions. This article describes the use of high-power diode lasers to perform 3 minor oral surgical procedures--biopsy, lingual frenectomy, and operculectomy--in 2 children. Read More

Pyogenic granuloma (PG) is a benign nonneoplastic mucocutaneous lesion. It occurs as a result of chronic irritation or due to hormonal changes. The most favorable site for this fairly common lesion is gingiva, but rarely, it can occur outside the oral cavity, later often difficult to diagnose, as a diverse group of the pathologic process can produce such lesions outside the oral cavity.

Pyogenic granuloma is one of the most common vascular tumours. The cause of pyogenic granuloma was previously thought to be an inflammatory reaction with consecutive stimulation of endothelial cell proliferation. However, recent studies suggest that pyogenic granuloma may be driven by constitutive activation of the mitogen-activated protein kinase pathway. Read More

Background: Lobular capillary hemangiomas typically present as skin or oral mucosa lesions and have rarely been described in unusual sites, including the gastrointestinal tract. Most colonic lobular capillary hemangiomas, either asymptomatic or associated with GI bleeding, have been amenable to endoscopic treatment in literatures. . Read More

Pyogenic granuloma (PG) is an oral reactive inflammatory hyperplasia of connective tissue that can occur in response to hormonal changes and local irritation such as calculus, fractured teeth, rough dental restorations, and foreign materials. It is nonneoplastic and predominant in the second decade of life in young adult females. The most common site of involvement is the gingiva. Read More

Purpose: Pterygium is a non-cancerous, fibrovascular growth of the bulbar conjunctiva that can cause visual disturbance, ocular pain, and cosmetic concerns. Surgical management is required in certain cases, which consists of excising the pterygium and associated Tenon's, then overlaying the bare sclera with an autograft or amniotic membrane using glue or sutures. The purpose of this study is to assess outcomes of pterygium repair using a newly developed self-adhesive amniotic membrane that does not require glue or sutures for fixation. Read More

Laryngeal hemangioma is a rare benign tumor of the larynx with predilection for a supraglottal subsite. Common presentations include hoarseness, dyspnea, and dysphagia, with a typical appearance of a reddish-purplish mass. A capillary form of the tumor, lobular capillary hemangioma (LCH) is extremely rare in adults and is predominantly unilateral. Read More

Oral lesions may be the initial or only manifestation of leukemia and can be the key to early diagnosis. The varied nature of presenting signs and dentists' general lack of familiarity with oral presentations makes diagnosis challenging. This retrospective review reports a series of cases of leukemia to familiarize dentists with the oral manifestations and facilitate earlier diagnosis or recognition of relapse of this life-threatening disease.

The aim of the present article is to present the clinical case of a large peripheral ossifying fibroma that evolved from a previously diagnosed pyogenic granuloma in a 50-year-old woman. The patient was referred for treatment of a lesion over the buccal and palatal gingiva close to the left upper first molar. It was purplish-red in color, approximately 3 cm in diameter, having a smooth surface, a pedicled and bleeding base, with seven years of evolution, and diagnosed as pyogenic granuloma. Read More
