Neoplasms – tumor diseases (C00-D48).
- Benign neoplasms in the breast area such as fibroadenoma (consist of proliferated connective tissue surrounding the glandular lobules, often growing in small nodules; most common in younger women (15 to 30 years of age); another peak age is 45 to 55 years)[palpation (palpation examination): usually 1-2 cm in size, painless, shifting nodules of firm consistency] or lipoma (fatty tumor)
- Mammary carcinoma (breast cancer)[Palpation (palpation examination): painless, rough lump, especially in the upper right quadrant, near the armpit (here occur about 50% of all carcinomas), etc.; see under symptoms or complaints of breast cancer].
- Mammary cyst (the fluid-filled cavities arise from dilated milk ducts and glandular lobules (lobules))[Palpation (palpation): usually 1-2 cm large, painless, displaceable lumps of firm consistency]
- Phylloid tumor (synonyms: cystosarcoma phylloides; phylloides tumor); very rare mammary tumor in adult women (about 1% of all mammary gland tumors). It is considered a special form of fibroadenoma. It grows larger than fibroadenoma, grows faster and finger-shaped, as if infiltrating, into the surrounding area. This growth has also led to the name cystosarcoma phylloides, as the rare sarcomas (very malignant, flesh-like soft tissue tumors) of the breast show similar growth. The tumors can become very large and cause significant deformities of the breast.[Palpation (palpation examination): usually larger than fibroadenomas and, like them, easy to palpate; surface irregular; the phylloid tumor may come out through the skin “cauliflower-like”].
- Parachordoma (synonym: Dabska tumor): myoepithelial carcinoma of soft tissue (extremely rare)[sonography: echocomplex, partly cystic structure with sharp demarcation from surrounding tissues]
