Cystás

Cystás is an adjectival form used in some medical and scientific contexts to indicate the presence of cysts or cyst-like structures within tissues or organs. The term is derived from cyst, with roots in Greek, and resembles the English adjective cystic; in English-language medical literature cystic is the standard form. Cystás may appear in translations or in languages that adapt terms from Greek or Latin.

In pathology, cystás changes refer to the development or appearance of cysts—bladder‑like cavities lined by epithelium or by other tissue types—within an organ. Cysts can arise from ductal dilation, congenital abnormalities, developmental processes, or degenerative changes. Cystic lesions vary in significance from benign and incidental to part of a malignant process with cystic components.

Common organ systems where cystás or cystic changes are described include:

- Kidneys: cysts ranging from simple renal cysts to polycystic kidney disease

- Liver: hepatic cysts and polycystic liver disease

- Pancreas: pancreatic cysts, including mucinous cystic neoplasms

- Ovaries: functional follicular cysts and corpus luteum cysts

- Lungs: cystic lung diseases with air-filled spaces

Diagnosis typically relies on imaging techniques such as ultrasound, computed tomography, or magnetic resonance imaging, often complemented by aspiration or histopathological analysis to assess benignity or malignancy. Treatment is individualized and may involve monitoring, drainage, surgical removal of symptomatic or suspicious cysts, or targeted therapy for underlying conditions.
