Desmoid tumors of the breast are rare, constituting 4% of extra-abdominal cases and 0.2–0.3% of breast tumors. [27] [24] Although benign, they can mimic breast cancer on physical examination, mammography and breast ultrasound and can also be locally invasive. Even though they occur sporadically, they can also be seen as a part of Gardner's ...
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
Due to presence of these tumors, DIPNECH is classified as a pre-malignant condition. [1] Although there have been reports of atypical carcinoids with local lymph node involvement, there are no reports of more aggressive neuroendocrine tumors, such as large cell neuroendocrine or small cell lung cancer, associated with DIPNECH.

A chylothorax is an abnormal accumulation of chyle, a type of lipid-rich lymph, in the pleural space surrounding the lung.The lymphatic vessels of the digestive system normally return lipids absorbed from the small bowel via the thoracic duct, which ascends behind the esophagus to drain into the left brachiocephalic vein.
Premalignant lesions are morphologically atypical tissue which appear abnormal when viewed under the microscope, and which are more likely to progress to cancer than normal tissue. [7] Precancerous conditions and lesions affect a variety of organ systems, including the skin, oral cavity, stomach, colon, lung, and hematological system.
Between 26% and 80% of TSC patients have benign tumors of the kidneys called angiomyolipomas, with hematuria being the most frequent presenting symptom. [ 8 ] TSC angiomyolipomas differ from non-TSC angiomyolipomas in age of presentation (31.5 years vs 53.6 years), mean tumor size (8.2 cm vs 4.5 cm), and percentage of cases requiring surgical ...
Leiomyoma is the most common benign mesenchymal tumor of esophagus and second most common benign tumor of the small bowel (with gastrointestinal stromal tumor as most common). [7] Although leiomyoma is the most common benign esophageal tumor, malignant carcinoma is still 50 times more likely. [ 8 ]
Gardner syndrome is an autosomal dominant form of polyposis characterized by the presence of multiple polyps in the colon together with tumors outside the colon. [3] The extracolonic tumors may include osteomas of the skull, thyroid cancer , epidermoid cysts , fibromas , [ 4 ] as well as the occurrence of desmoid tumors in approximately 15% of ...
