Abstract Abstract: Myoid hamartomas of the breast are extremely rare breast lesions, with a poorly understood pathogenesis. A 60‐year‐old woman presented with a palpable mass in the right breast. Breast ultrasonography and mammography showed the presence of a breast lesion with benign characters, but were not diagnostic Introduction. Gastric polyps are encountered in approximately 1%-6.35% of endoscopies.1-3 Gastric polyps are rarely symptomatic and are usually discovered incidentally on endoscopy.1 The larger gastric polyps may present with bleeding, anemia, obstructive symptoms, and pain.4 The most common types of gastric polyps are fundic gland polyps (FGPs), hyperplastic polyps, and adenomas.3,5,6.

  4. The special feature of a hamartoma is that it is not made up of unusual cells but rather the components of normal breast tissue - including supporting tissues, glandular tissue and fat (hence the name: fibro- supporting tissues, adeno- glandular tissue and lipo- fat). These lesions are typically round or oval as seen on a mammogram or ultrasound
  5. Surgical resection of the mass was necessary for definitive diagnosis. The pathology proved to be a lactating adenoma, which is the most prevalent breast mass in young pregnant females. The large size of this tumor, and the presentation of breast erythema and edema raised the possibility of inflammatory breast cancer

  7. Hamartoma, benign tumourlike growth made up of normal mature cells in abnormal number or distribution. While malignant tumours contain poorly differentiated cells, hamartomas consist of distinct cell types retaining normal functions. Because their growth is limited, hamartomas are not true tumours and some, such as hemangiomas that occur as birthmarks, may disappear with time

Abstract: Pseudoangiomatous stromal hyperplasia (PASH) is a benign mesenchymal lesion of the breast characterized by dense collagenous stroma forming pseudoangiomatous capillary-like spaces lined by slender spindle cells. A rare condition overall, PASH is most common in premenopausal women, though cases have been described at ages ranging from 14 to 86, and in men, usually associated. Hamartomatous polyps of the colorectum develop sporadically or in patients with hamartomatous polyposis syndromes, such as Peutz-Jeghers syndrome, juvenile polyposis, and phosphatase and tensin homologue (PTEN) hamartoma tumor syndrome. Although hamartomatous polyps are benign lesions comprising a variable admixture of nonneoplastic epithelial. Fibroadenomas of the Breast. Fibroadenomas are common benign (non-cancerous) breast tumors made up of both glandular tissue and stromal (connective) tissue. Fibroadenomas are most common in women in their 20s and 30s, but they can be found in women of any age. They tend to shrink after a woman goes through menopause Pathology.

A Hamartoma is mostly a benign mass of disorganized tissue native to a particular anatomical location. Most of the hamartomas are usually benign, but malignant transformation may occur. Hamartomas can grow almost anywhere on the body and usually are found in the lungs, hypothalamus, breast, and colon, etc. [1] Most of the cases are asymptomatic. Myofibroblastoma (MFB) and low-grade adenosquamous carcinoma (LGASC) are rare tumours in the breast, respectively. However, a collision tumour of the two types has never been reported. A 42-year-old female presented with a palpable mass in diameter of about 2.5 cm in the left breast. Morphologically, the lesion was predominately composed of bland spindle cells admixed with some islands of. Some consider a splenic hamartoma to be a neoplasm (a form of hemangioma or lymphangioma) or possibly a posttraumatic lesion (, 17 24).
