Aggressive angiomyxoma is a rare, benign but locally aggressive mesenchymal neoplasm. We report the sonographic findings in a case of histologically proven aggressive angiomyxoma of the bladder. Sonography revealed a solid polypoid mass 2 cm in diameter with sharply demarcated borders, a heterogeneous echotexture, and a slightly hyperechoic rim.

Deep or aggressive angiomyxoma is an uncommon neoplasm of the pelvis. Although deep angiomyxoma is a benign tumor, its tendency to infiltrate soft tissues and reach a large size (typically > 10 cm) indicates aggressive biological behavior. It is usually present in female patients, but there have been recent reports of male-aggressive angiomyxoma.

Cardiac myxoma in its morphology is a typical benign tumor, meanwhile, the fact of its localization in the heart chamber, directly in the constant blood flow, largely determines the clinical behavior of this neoplasm, which is often manifested by the development of characteristics that formally determine the aggressive and even malignant nature of the course. Accordingly, the malignancy of cardiac myxoma is determined more by its clinical behavior (recurrence, multifocality of the lesion, the presence of mechanisms of spread similar to metastasis) rather than by its histological picture. In the structure of primary benign tumors of the heart, myxoma occupies a dominant position and its incidence is up to 85%.

Aggressive angiomyxoma (AA) is a very rare tumour arising from the vulvovaginal mesenchymal tissue. The literature has not reported its co-existence with hidradenitis suppurativa (HS). A 30-year-old female presented with a giant pedunculated mass arising from a scarred and disfigured perineum for 3 years.

Objective: and rationale: Odontogenic myxoma is an uncommon odontogenic tumor with locally aggressive behavior. The clinicopathological studies of odontogenic myxoma in Asian countries are very limited and only few studies have investigated the immunohistochemical profiles of the tumor. This study aims to investigate the clinicopathological and immunohistochemical features of odontogenic myxoma at the Faculty of Dentistry, Mahidol University over a 15-year period.

Deep angiomyxoma (DA) is a rare, slow-growing soft tissue tumor typically affecting women of reproductive age. Despite its benign histology, it poses significant clinical challenges due to local invasiveness and high recurrence. Accurate diagnosis through radiologic imaging, particularly MRI, is essential for guiding treatment.
