“…The appearance of these findings varied among different parts of the masses, and as for the disease etiology, Omura et al suggest the negative spiral theory during the healing process as follows [8]. First, a blood clot accumulates in the closed space owing to bleeding of various causes, including hemangioma formation, facial injury, or inflammation.…”

“…This type of lesion was reported in the Japanese literature in 1917 as a “blood boil of the maxillary sinus” by Tadokoro and is comparatively well known in Japan as one of the differential diagnoses of maxillary carcinoma. However, in the English literature, this type of lesion tends to be referred to as hemangioma of the maxillary sinus, organized hematoma of the maxillary sinus, or organized hematoma of the maxillary sinus mimicking tumor [1–8]. Although their clinical manifestations are very similar, the relationships between these entities have not been described.…”

Objective. To study the clinical and pathological characteristics of patients with organized hematoma with malignant features in maxillary sinuses. Subjects and Methods. This was a retrospective study of five patients who were treated surgically for organized hematoma. The preoperative CT and MRI findings were studied clinically. The expressions of CD31, CD34, and periostin in surgical samples were investigated by immunohistochemistry. Results. The clinical features of organized hematoma, such as a mass expanding from the maxillary sinus with bone destruction, resembled those of maxillary carcinoma. However, CT and MRI provided sufficient and useful information to differentiate this condition from malignancy. Surgical resection was the first-line treatment because of the presence of a firm capsule. Characteristic histopathological findings were a mixture of dilated vessels, hemorrhage, fibrin exudation, fibrosis, hyalinization, and neovascularization. The expressions of periostin, CD31, and CD34 were observed in organized hematoma of the maxillary sinus. Conclusion. The expressions of periostin, CD31, and CD34 were observed in organized hematoma of the maxillary sinus. Organized hematoma is characterized pathologically by a mixture of bleeding, dilated vessels, hemorrhage, fibrin exudation, fibrosis, hyalinization, and neovascularization. CT and MRI show heterogeneous findings reflecting a mixture of these pathological entities.

“…On the other hand, the fibrous capsule around the hematoma prevents the absorption and facilitates its progressive expansion. Various causes can lead to the initial blood collection, such as bleeding diathesis, postoperative complication, radiation therapy and trauma [1,4,5].Our patient, despite our persistent question, did not report us a neck injury, while the hematological tests were normal Many authors have reported several cases of organized hematoma in the head and the neck (Table 1). It is appeared in all age groups (2-85 years) with a slight predominance in males (57%).…”

Expanded or small organizing hematoma is found everywhere in the body and frequently simulates a neoplasm. It has a central mass of blood, a wall of granulation tissue, and a dense, fibrous tissue at the periphery. We report a case of an enormous organizing hematoma of the left carotid neck triangle, in a patient without a history of trauma in the neck or blood disorders and also review the literature.

“…The central part of the lesion shows low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, while the peripheral rim of the lesion has low signal intensity on T2-weighted images. 3 These features differ from those of infectious, inflammatory and neoplastic lesions. The treatment of choice for organised haematoma is complete surgical evacuation.…”
