Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect.

A carotid-cavernous sinus fistula is a rare condition in which an abnormal communication exists between the internal or external carotid artery and the cavernous sinus. It typically occurs within a few weeks after craniomaxillofacial trauma. In most cases, the carotid-cavernous sinus fistula occurs on the same side as the craniomaxillofacial fracture. We report a case of delayed carotidcavernous sinus fistula that developed symptoms 7 months after the craniomaxillofacial fracture. The fistula developed on the side opposite to that of the craniomaxillofacial fracture. Based on our experience with this case, we recommend a long follow-up period of 7–8 months after the occurrence of a craniomaxillofacial fracture. We also recommend that the follow-up should include consideration of the side contralateral to the injury.

Bullosis diabeticorum (BD) is a distinct, spontaneous, noninflammatory, and blistering lesion that develops predominantly in the acral skin of patients with diabetes mellitus (DM). BD is a rare disease that develops in patients with longterm DM and not well known to physicians and often fails to be diagnosed. The lesions are known to spontaneously heal in most patients in 2 to 6 weeks. Wound care is required to prevent secondary infection of the blisters. However, if infection develops and progresses to necrosis, surgical intervention including debridement and reconstruction may be necessary. We report a case of BD in a patient with relatively well controlled DM, whose wounds progressed to necrosis and then spontaneously healed with dressings.
