Polyps may be sessile or pedunculated and vary considerably in size. Incidence of polyps ranges from 7 to 50%; the higher figure includes very small polyps (usually hyperplastic polyps or adenomas) found at autopsy. Polyps, often multiple, occur most commonly in the rectum and sigmoid and decrease in frequency toward the cecum.

A pulmonary cyst is a round air space defined pathologically by an epithelial or fibrous outer wall and radiographically as a round parenchymal lucency or low attenuation area with a well-defined interface with normal lung. 1 Cysts are common in otherwise normal individuals but may occur in association with other lung diseases. Cysts must be differentiated from pulmonary cavities.
Inclusion cysts are the most common cysts of the vulva. The vulva is the area that contains the external genital organs. Inclusion cysts may also develop in the vagina.

Here, we describe a year-old man with a history of multiple hospitalizations for lung infection who presented to the pulmonary clinic with a complaint of worsening chronic productive cough in the previous year.
Cysts are commonly seen on CT scans of the lungs, and diagnosis can be challenging. Clinical and radiographic features combined with a multidisciplinary approach may help differentiate among various disease entities, allowing correct diagnosis. It is important to distinguish cysts from cavities because they each have distinct etiologies and associated clinical disorders. Conditions such as.
A cyst typically presents as a pea-sized lump anywhere on the body. Cysts are usually painless but there is a possibility of developing an infection in the cyst. Such a cyst is known as an "infected cyst", and is filled with pus. An infected perianal cyst typically .
