Malignant adenomyoepithelioma of the breast: an immunohistochemical, cytophotometric, and ultrastructural study of a case with lung metastases. Presented herein is the first case of malignant adenomyoepithelioma (malignant AME) of the breast combined with invasive lobular carcinoma (ILC) in a 53-year-old woman. BACKGROUND: Malignant adenomyoepithelioma and adenoid cystic carcinoma are both rare malignant epithelial-myoepithelial tumors of the breast. It is usually benign; however, there are reports of malignant behaviour. Malignant transformation has been associated with homozygous deletion of CDKN2A or somatic mutations in TERT, but remains (13.) The histomorphologic appearance can mimic invasive ductal carcinoma, the most common type of invasive breast cancer Axillary lymph node metastases are thought to be unusual, and it has been recently suggested that axillary node dissection is not indicated unless clinically palpable. Biphasic malignant adenomyoepithelioma is a rare neoplasm, so far only reported in women who range in age from 26 to 76 years. Metastases associated with these tumours are usually haematogenous. The latter normally comprises lesions where the malignant component is derived either from the luminal epithelium or the myoepithelium. J Clin Pathol. malignant [2].

Malignant adenomyoepithelioma of the breast is a rare lesion characterised by malignant proliferation of epithelial and myoepithelial cells that show characteristic histological and immunohistochemical features. Malignant adenomyoepithelioma (MAME) of the breast is a rare lesion characterized by dual population of epithelial and myoepithelial cells which one or both components show malignant features. Discussion: 124, no. Malignant adenomyoepithelioma and adenoid cystic carcinoma are both rare malignant epithelial-myoepithelial tumors of the breast. Partial lobectomy was performed for lung lesions and initial diagnosis was epithelial-myoepithelial carcinoma.

The malignant adenomyoepithelioma is a rare tumour of the salivary type in the breast, reported in the literature as a low-grade malignant neoplasm. A case of malignant adenomyoepithelioma of the breast is reported. Tumor sizes range from 1 to 15 cm. Malignant adenomyoepithelioma with invasion (A) showing malignant biphasic papillary growth pattern in some areas (B), with other areas showing evidence of stromal invasion which is focal in one area (C) and extensive in other area (D) but these show the same morphology and immunoprofile of the main tumour. Adenomyoepithelioma is an extremely rare primary cutaneous neoplasm. Malignant adenomyoepithelioma has so far been reported only in women, and the oldest patient was 76 years old.

Shortly after, two lung nodules were detected through a CT scan, and a diagnosis of malignant adenomyoepithelioma was rendered. Malignant adenomyoepithelioma of the breast is a rare tumour with around 30 cases reported in the literature. Abstract. Adenomyoepithelioma (AME) of the breast is a rare subtype of breast tumor. Only few cases have been reported in the literature. Malignant adenomyoepithelioma (AME) and adenoid cystic carcinoma (ACC) are both rare malignant epithelial-myoepithelial lesions of the breast.

A 61-year-old female presented with a palpable painless mass in the right breast. The histomorphologic appearance can mimic invasive ductal carcinoma, the most common type of invasive breast cancer We report a primary cutaneous adenomyoepithelioma (pcAME) with malignant features arising from a spiradenoma in a 39-year-old female patient. Malignant change in an adenomyoepithelioma has been previously reported. Only a few cases have been reported in the literature and establishing the diagnosis, determining the optimal therapy as well as predicting the outcome are problematic issues due to the rarity of this disease. CONCLUSION. Adenomyoepithelioma. Malignant change of one or both cell types may occur and is thought to be associated with hematogenous, rather than lymphatic, metastasis. By definition they have a prominent component of my oepithelial cells, in addition to glandular elements lined by epithelial cells. DISUCSSION.
