“…Immunohistochemically, AAMs show positivity for vimentin, desmin and smooth muscle actin. The immunoreactivity of the Oestrogen (ER) and the Progesterone (PR) receptors have been described to be the most characteristic feature [4]. AAM needs to be differentiated microscopically from superficial angiomyxomas, fibroepithelial polyps, angiomyofibroblastomas, myxoid neurilemmomas, myxoid malignant fibrous histiocytomas, myxoid lipomatous tumours, myxoid leiomyomas and cellular angiofibromas.…”

Introduction: Aggressive angiomyxoma are rare myxoid soft tissue neoplasms, affecting the pelvis and the perineum, rarely encountered in extragenital sites, with a marked preponderance for females in the reproductive age group. AAMs are thought to be benign, locally infiltrative and nonmetastasizing. Here is case report of AAM located in the posterior chest wall.Case report: 50-year-old female presented with complaints of swelling over the back since 1 year. Insidious in nature, clinically suspecting lipoma. MRI done gave an impression of cystic lesion likely to be a sebaceous cyst. Conclusion:AAMs are rare slow growing tumours with a high recurrence rate, seen almost exclusively in the pelviperineal region. The present case is unique in being located in the posterior chest wall. A histopathological examination, combined with radiological correlation, helped in distinguishing these lesions from the more commonly occurring similar entities, when they are located in sites other tan genital regions.

“…Microscopic, clinicopathological, and immunoreactivity features are important in differentiating aggressive angiomyxoma from other tumors of mesenchymal origin and myxoid background. [ 49 ] Histological manifestations include hypocellular myxoid stroma with scattered spindle-shaped cells. [ 51 ]…”

Most of male breast masses are benign with gynecomastia being the most common entity encountered. Primary male breast cancer accounts for less than 1% of the total number of breast cancer. Male breast can be affected by a variety of conditions affecting the female breast with less frequency due to the lack of hormonal influence and consequent glandular sub-development. Imaging features of male breast masses are quite similar to the female breast. Therefore, using the knowledge of the female breast and applying it may help in the diagnosis and management of male breast abnormalities. In this article, we aim to review a variety of unusual male breast masses. We discuss the demographics of male breast tumors, describe the diagnostic algorithm for evaluating male breast masses, and review the imaging features of rare breast masses and mimickers of male breast cancer.
