At surgery, it was found to be a soft 3.0 × 2.1 × 1.8 cm tumor of the submandibular salivary gland. The photo shows the characteristic dark color of an oncocytoma, a rare type of benign neoplasm, at the left side of the image (the normal lobulated salivary gland tissue is to the right).
A corpus luteum cyst or luteal cyst is a type of ovarian cyst which may rupture about the time of menstruation, and take up to three months to disappear entirely. A corpus luteum cyst does not often occur in women over the age of 50, because eggs are no longer being released after menopause.
Typical sizes reported are 1 to 8 cm in diameter. [1] PTCs may be found at surgery or during an imaging examination that is performed for another reason. Larger lesions may reach 20 or more cm in diameter and become symptomatic exerting pressure and pain symptoms in the lower abdomen. [ 3 ]
[3] [6] Bleeding from the blood vessels of the polyp contributes to an increase of blood loss during menstruation and blood "spotting" between menstrual periods, or after menopause. [7] If the polyp protrudes through the cervix into the vagina, pain ( dysmenorrhea ) may result.
While these symptoms may indicate cancer, they can also have other causes. [1] Over 100 types of cancers affect humans. [7] Tobacco use is the cause of about 22% of cancer deaths. [2] Another 10% are due to obesity, poor diet, lack of physical activity or excessive alcohol consumption.
In the case of an existing tumour, a biopsy would then be required to make a diagnosis and distinguish whether the tumour is malignant or benign. [8] This involves examination of a small sample of the tissue in a laboratory. [8] If detected as a malignant tumour, treatment is necessary; treatment during early stages is most effective. [8]
The cut surface of a 3.9 × 3.5 × 2.5 cm tumor is triangular, with a bulging peripheral portion and a somewhat fibrotic center. It was surrounded by the heart, left lower lobe of the lung, aorta, esophagus, and diaphragm, and had been 1.8 cm in diameter 7 years before.
