Patient: Male, 32-year-old Final Diagnosis: Cavernous hemangioma Symptoms: Epistaxis • facial asymmetry • nasal obstruction Medication: — Clinical Procedure: — Specialty: Otolaryngology Objective: Rare disease Background: Hemangiomas are commonly located in the head and neck and rarely in the paranasal sinuses. These are benign vascular lesions, but with an increased risk of bleeding. The surgical approach must have detailed prior planning, given the increased risk of intraoperative bleeding. We herein describe the case of a 32-year-old male patient with recurrent epistaxis, nasal obstruction, and facial deformity due to a giant cavernous hemangioma successfully treated by endoscopic sinus surgery. Case Report: A 32-year-old man had nasal obstruction and intermittent epistaxis for 2 months. Physical examination also revealed facial deformity with enlargement of the nasal base and bulging in the maxillary region on the right. A soft and friable lesion occupying the entire right nasal cavity without bone erosion was observed on computed tomography (CT scan). Before surgery, the patient underwent angiographic evaluation, with evidence of main irrigation of the lesion by the right maxillary artery, which was then embolized. The patient underwent endoscopic nasal surgery. He maintained postoperative follow-up for 18 months, without recurrence of the lesion. Anatomopathological examination confirmed a cavernous hemangioma. Conclusions: Cavernous hemangioma is a benign lesion of the paranasal sinuses. Due to non-specific clinical and radiological findings, its preoperative diagnosis is always challenging. The high index of suspicion of the malignancy should only be discarded after complete anatomopathological evaluation. A correct diagnosis is essential to avoid facial anatomical remodeling while excluding the diagnosis of other malignant lesions.

Cardiac tumors are uncommon conditions in medical practice, and among them, the most prevalent is the myxoma. Despite their benign nature, myxomas may have behavior suggestive of malignancy and serious consequences. They may have cardiovascular repercussions associated with nonspecific systemic manifestations, which often hinder their diagnosis, benefiting their evolution and increasing the risks of serious complications, including embolic alterations and death. We present, in this work, the case report of a child admitted to the Hospital Infantil Público de Palmas (HIPP), with clinical history of abdominal distension, adynamia, hyporexia and intermittent fever, initially diagnosed with right atrial myxoma. The patient had different epidemiological characteristics than those described in the literature for cardiac myxomas. This, combined with the fact that cardiac myxomas have a low incidence and commonly present in non-specific cardiovascular and constitutional manifestations, made it difficult to diagnose and delay surgical treatment. Attention to the possibility of this disease and the echocardiogram in the evaluations may facilitate the early diagnosis of this benign cardiac neoplasia.
