Oral foregut cysts are congenital choristomas that arise in the oral cavity during embryonic development from remnants of foregut-derived epithelium. This is an unusual report of a neonate with a large congenital sublingual cystic lesion, extending superficially from the left ventral tongue to the anterior floor of the mouth, impeding breast-feeding. The differential diagnosis included dermoid cyst, epidermoid cyst, mucous retention cyst, and oral lymphangioma. The treatment of choice was enucleation under general anesthesia. Histology showed a cystic lesion with a ciliated pseudostratified columnar epithelium with numerous goblet cells. Immunohistochemistry was positive for cytokeratin 7 and thyroid transcription factor 1 and negative for cytokeratin 20, resulting in a final diagnosis of an oral foregut cyst. Three weeks after surgery, the tongue had healed with good mobility, and breast-feeding could be established. No recurrence was present at 6 months of follow-up.

Cavernous hemangiomas are benign malformations of vascular origin, usually well circumscribed and slow to grow. These lesions can be asymptomatic, being discovered unintentionally in imaging exams or symptomatic, indicated mainly by the presence of proptosis, diplopia, and visual disturbances by optic nerve compression. The complementary exams involve computed tomography associated with contrast, color Doppler, magnetic resonance, and angiography. Treatment can be conservative or surgical depending on the case, and the open therapy usually involves lateral, supraorbital, transconjunctival, transantral, pterional, transnasal, and extradural endoscopic orbitotomy. The present study aims to report a recurrent case of hemangioma in the orbital cavity signaled by ocular proptosis, hyperemia, and ocular pain.The lesion was achieved through the Weber-Ferguson access with zygomatic osteotomy and preservation of the infraorbital nerve. The excision of the lesion was performed, and the previously displaced fragments were fixed with 1.5 mm mini plates. The patient has a chance of progressing with visual impairment due to considerable manipulation of the optic nerve and is being followed up.The reported case showed a successful diagnosis and therapeutic conduct, remaining now in the evolution and follow-up scenario.
