  2. Tubular carcinoma - Wikipedia

    en.wikipedia.org/wiki/Tubular_carcinoma

    Although tubular carcinoma has been considered a special-type tumor, [a] recent trend has been to classify it as a low-grade, invasive NOS carcinoma because there is a continuous spectrum from pure tubular carcinomas to mixed NOS [b] carcinomas with tubular features, depending on the percentage of the lesion that displays tubular features.

    SPC is considered invasive when the tumor nests have a characteristic jigsaw growth pattern with ragged and irregular margins with the loss of myoepithelial cells at the site(s) of invasion. [21] Rarely, invasive SPC occurs with nearby invasive carcinoma of NST, lobular carcinoma, cribriform carcinoma, or tubular carcinoma breast tumors. [3]

    It shows the typical features of invasive breast cancer with infiltrative growth pattern, here including invasion into adipose tissue and with an associated fibrous or desmoplastic stromal response. It has the criterion of more than 90% of the tumor composed of small, ovoid or angulated tubules with open lumina.

  5. Adenoma - Wikipedia

    en.wikipedia.org/wiki/Adenoma

    Adenoma is a benign tumor of glandular tissue, such as the mucosa of stomach, small intestine, and colon, in which tumor cells form glands or gland-like structures. In hollow organs (digestive tract), the adenoma grows into the lumen - adenomatous polyp or polypoid adenoma. Adenomatous polyps may be classified based on morphology in order to ...

    Syringocystadenoma papilliferum is a rare non-malignant adnexal neoplasm that develops from apocrine or eccrine sweat glands and can be identified histologically by cystic, papillary, and ductal invaginations into the dermis lined by double-layered outer cuboidal and luminal high columnar epithelium and connected to the epidermis.

    Breast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these ...

    An adenomyoepithelioma of the breast is a rare tumour in the breast composed of glandular elements (adeno-) and myoepithelial cells. It is usually benign; [1] however, there are reports of malignant behaviour. [2] The histomorphologic appearance can mimic invasive ductal carcinoma, the most common type of invasive breast cancer.
