Key Clinical Message: Osseous choristoma is a rare entity, mainly found on the posterior tongue. It is described as a nodular or exophytic lesion with firm to hard consistency. Clinicians should consider osseous choristoma when confronting lesions with the same features. Osseous choristoma is an unusual growth of ectopic bone in the soft tissue. This lesion is extremely rare, with a few cases reported in the literature, and they typically appear in the head and neck region, particularly the posterior tongue. The current report presents a case of osseous choristoma in the palate of a 51‐year‐old female. The patient had slight discomfort, which was resolved after surgical excision of the lesion, and no recurrence was observed. This research presents an instance of osseous choristoma in a less common location and concurrently acts as a review of this rare condition.

Extramedullary plasmacytomas (EMP) are uncommon solitary tumors composed of neoplastic plasma cells occurring outside the bone. These lesions are of clinical significance due to their potential progression to multiple myeloma (MM), a more systemic and serious plasma cell malignancy. Although EMPs primarily arise in the head and neck region, cases involving the oral cavity are particularly rare. This report presents a case of EMP in a 59‐year‐old Iranian female, who developed a mass on the left buccal mucosa, an atypical site for this type of lesion. The patient presented with a 1‐month history of a painful swelling on her left buccal mucosa. Clinical examination revealed a firm, exophytic lesion with a smooth surface. Histopathological analysis, supported by immunohistochemical staining, confirmed the diagnosis of EMP. The lesion was treated successfully through a combination of surgical excision and radiotherapy at a dose of 40 Gy. This case underscores the importance of early diagnosis and treatment of EMP, particularly in rare locations, to prevent progression to MM and improve patient outcomes. Our findings contribute to the limited body of literature on EMPs in the oral cavity, highlighting the need for awareness of such presentations among clinicians.

Objectives: Gingiva is one of the supporting tissues around the teeth that can be affected by various neoplastic or nonneoplastic lesions. Previous studies have examined several types of gingival lesions, but the lack of a standardized classification system has hindered meaningful comparisons. Additionally, many studies focused primarily on reactive lesions. Our study aims to contribute to the understanding of gingival lesions by investigating their prevalence across age groups, genders, sites, and by their clinical presentation. This research could lead to improved diagnostic accuracy and treatment strategies.Materials and Methods: This retrospective study explores the prevalence of gingival lesions based on biopsies during a 22‐year span. The patient's demographic details, including age, gender, and lesion's clinical presentation were systematically collected. These lesions were categorized into six groups. Descriptive statistics, χ² test of independence, and one‐way ANOVA were used for data analysis.Results: Among the 7668 biopsied lesions, 684 (8.9%) lesions were located in the gingiva, with a greater occurrence in women (63.5%). Soft tissue tumors represented the most prevalent group in the gingival lesions (72.1%), and peripheral giant cell granuloma (PGCG) was the most frequent lesion (21.2%), followed by, pyogenic granuloma (19.3%), peripheral ossifying fibroma (17.8%) and focal fibrous hyperplasia (7.6%); all of which predominantly affected women, with mean ages falling in the fourth decade of life. Squamous cell carcinoma was recognized as the most common malignancy.Conclusion: In this study, PGCG was found to be the most common lesion in the gingiva in Iranian population. Further analysis using a unanimous categorization is required to confirm these results.

Angiolipomas are benign mesenchymal neoplasms composed of mature adipocytes and vascular channels, typically occurring in subcutaneous tissue. Intraosseous is extremely rare and has been described in only 22 cases in the previous studies, affecting mainly the mandible, calvarium, ribs, and long bones. To our knowledge, there has not been one reported case in the maxilla. We report the first case of intraosseous angiolipoma of the maxilla and review the literature to emphasize its diagnostic challenge and clinical significance. A 46‐year‐old male patient presented for routine dental checkup with no symptoms and an uneventful clinical examination. His past medical history was extraction of maxillary molars and surgical removal of radicular cysts from the same area five years ago. Panoramic radiograph showed well‐defined unilocular radiolucency in the left posterior maxilla. Cone‐beam computed tomography established cortical perforation of the buccal and palatal plates and sinus floor involvement. Based on imaging and history, a preliminary diagnosis of residual cyst was rendered. Enucleation and curettage with primary closure was performed to manage the lesion. During surgery, the mass was found to be adherent to the buccal fat pad and surrounding musculature. The excised specimen was 2.5 × 1.5 × 1.1 cm and yellowish in hue. Histopathology revealed mature adipose tissue scattered with several thin‐walled vessels in a lobulated pattern covered with a fibrous capsule. There was evidence of muscle fibers, hemorrhage, and nerve bundles, however no malignancy or atypia was observed. The final diagnosis was intraosseous angiolipoma. The lesion was removed by surgery, and the postoperative course was uneventful. No recurrence was observed during 1‐year follow‐up. This article presents the first case of intraosseous angiolipoma of the maxilla, contributing to the known anatomic distribution of this tumor.
