Choroidal osteoma is a rare, benign, osseous choristoma presenting as an orange-yellow, well-defined fundus mass. It presents unilaterally in most cases, has a predilection for the female sex, and favor a juxtapapillary location, becoming clinically manifest when it involves the macula. Almost 60% of eyes with osteoma may suffer significant visual loss. Choroidal osteomas can easily be mistaken for other conditions with similar presentations. We herein report two rare cases presentation of choroidal osteoma: a 74-year-old male with 2-year blurred vision in the right eye (RE) initially misdiagnosed with age-related macular degeneration received intravitreal injections and after a multimodal evaluation, following cataract surgery in RE, confirmed to be choroidal osteoma and a 19-year-old female with a history of choroidal hemangioma presented with blurred vision in her left eye (LE), with examination revealed an irregular orange-yellow lesion along the superotemporal arcade with serous macular detachment, later diagnosed as choroidal osteoma.

Abstract Background An ocular osseous choristoma is a growth of mature, compact bone in the ocular or periocular soft tissue, and it is the rarest form of ocular choristoma, accounting for only 1.7% of all epibulbar choristomas. Case presentation Herein we present the case of a 20-month-old girl who was referred to the oculoplasty clinic with a progressively growing mass in the left lateral canthus. It had been present since birth without ocular involvement. Upon examination the mass was firm with a smooth surface, measured 9 × 6 × 3 mm, and exhibited no episcleral attachment or ocular involvement. An excisional biopsy was performed, and the histopathological findings were consistent with osseous choristoma of the left lateral canthus. Conclusions This report highlights the importance of considering osseous choristoma in the differential diagnosis of eyelid lesions, particularly those that have been present since birth. It also emphasizes the need for further studies investigating associations between osseous choristomas and ocular canthi.

Epidermal nevus syndrome is a rare congenital disorder affecting only a few hundred people in the world. It has ophthalmic, dermatological, and neurological manifestations, with varied presentation. Here, we report a case of two-year-old child who presented with epibulbar mass in left eye, pigmented nevi over left side of the body and alopecia over left side of parieto-temporal scalp. Imaging confirmed epibulbar mass and presence of calcification of choroid on ipsilateral side with presence of arachnoid cyst of brain with underlying pachygyria. Neurological examination was normal and dermatologist confirmed presence of verrucous nevi over skin. Excisional biopsy of epibulbar mass revealed a complex choristoma with presence of lacrimal gland tissue. Underlying ocular findings were near normal with normal posterior segment. It is a rare form of epidermal nevus syndrome with near normal ocular findings in the presence of anterior and posterior choristoma, which has not been reported. [ABSTRACT FROM AUTHOR]

Tessier no. 7 clefts are characterized by macrostomia, facial muscular diastasis and maxillary and zygomatic bone abnormalities. It is caused by a lack of ectomesenchyme formation or penetration of the maxillary and mandibular processes during the fourth and fifth weeks of development. A case of bilateral transverse facial cleft with an accessory maxilla and an osseous choristoma is presented. The diagnosis of accessory maxilla was based on clinical findings due to the inaccessibility of orthopantomography and computed tomography scan. Orbicularis oris muscle reconstruction, cheiloplasty and excision of accessory maxilla were done. Histopathological examination of the bony lesion showed an osseous choristoma. There were no postoperative complications or local recurrence of the lesion excised. This case report demonstrates the importance of early diagnosis and intervention in maxillofacial congenital anomalies. Cheiloplasty restores function and gives the patient a natural appearance. The excision of accessory bone prevents further complications in the child's growth. [ABSTRACT FROM AUTHOR]

We report a case of a 40-year-old Japanese woman with a benign tongue tumor diagnosed as osseous choristoma of the tongue. Resection of the tongue tumor was performed under general anesthesia. The gross examination of the resected specimen showed a bone-like mass measuring 5 × 5 × 3 mm, surrounded by soft tissue. Based on the findings, a histopathological diagnosis of osseous choristoma was established. There was no evidence of tumor recurrence or distant metastasis during the 3-year follow-up.

Choristomas are proliferative growths that occur when normal tissue develops in abnormal locations and may resemble tumors. Oral choristomas commonly present as slow-growing, indolent, and firm masses. The diagnosis primarily relies on histopathologic examination. Given their tumor-like growth and developmental pathogenesis, it is critical to differentiate them from neoplasms. In this article, we present two clinical cases of oral choristomas, a cartilaginous choristoma, and an osseous choristoma of the tongue. We also offer a brief review of the literature discussing clinical presentation, microscopic features, and therapeutic options., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Masson SAS.

Osteomas are rare benign bony tumors located in the tongue area. In most cases, patients presenting with a lingual osteoma are asymptomatic but may complain of the sensation of having a foreign body. Fewer than 100 cases of lingual osteoma have been reported worldwide. Here, we present 2 cases of tongue base osteoma that were treated with excision under a laryngoscope. [ABSTRACT FROM AUTHOR]

Lingual osseous choristoma is a rare, benign, bony tumor without clear pathogenesis. Most patients present with an asymptomatic lump in the posterior tongue, while others may suffer from globus sensation, dysphagia, gagging, or irritation. Here, we present a case of lingual osseous choristoma in a pediatric patient managed with surgical excision., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Almujaiwel et al.)
