A myxoid tumor is a connective tissue tumor with a "myxoid" background, composed of clear, mucoid substance. [1] Atrial myxoma. This tumoral phenotype is shared by many tumoral entities: Myxomas. Atrial myxoma; Odontogenic myxoma; Cutaneous myxoma; Intramuscular myxoma; Myxoid hamartoma; Aggressive angiomyxoma; Myxoid leiomyoma; Chondromyxoid ...
Initially considered to be a type of histiocytoma termed fibrous histiocytoma or myxoid variant of malignant fibrous histiocytoma, [2] Angervall et al. termed this tumor myxofibrosarcoma in 1977. [3] In 2020, the World Health Organization reclassified MFS as a separate and distinct tumor [ 4 ] in the category of malignant fibroblastic and ...
Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.
In addition, larger masses can stretch the overlying breast tissue leading to nipple retraction, chest wall fixation, and in advanced cases, ulceration from pressure necrosis. [ 6 ] Phyllodes tumors can grow to a variety of sizes, ranging from 0.8 to 40 cm, with the average tumor growing to between 4 and 8 cm. [ 7 ] Their growth can be slow ...
Cutaneous myxoma appears as a little, slowly expanding dermal or subcutaneous lump that typically affects adults' heads and necks. [3] Alopecic lesions have been reported, [4] [5] characterized by hair tufts overlaying the lesion or even hypertrichosis. [6]
Breast cancer was the only type for which treatment advances prevented more deaths. Quitting smoking was found to be the most beneficial prevention strategy overall, credited for averting 3.45 ...
Myxomas may also occur outside the heart, usually in the skin and breast. Endocrine tumors may manifest as disorders such as Cushing syndrome . The most common endocrine gland manifestation is an ACTH-independent Cushing's syndrome due to primary pigmented nodular adrenocortical disease (PPNAD).
Undifferentiated pleomorphic sarcoma (UPS), also termed pleomorphic myofibrosarcoma, [1] high-grade myofibroblastic sarcoma, and high-grade myofibrosarcoma, [2] is characterized by the World Health Organization (WHO) as a rare, poorly differentiated neoplasm (i.e., an abnormal growth of cells that have an unclear identity and/or cell of origin).
