Marked reactive and degenerate changes in benign fluids may show marked nuclear atypia resulting in equivocal diagnosis. Pathological fracture: The main complication of simple bone cyst is a fracture. Interpretation of borderline and low grade lesions may prove difficult due to minimal morphological changes. Types of trauma associated with this cyst include falls, injuries, and. Cyst fluid analysis for amylase and carcinoembryonic antigen (CEA) are also helpful in distinguishing pseudocysts from neoplastic cysts that are mucinous. Causes are unknown, but it may result from back trauma. It is also possible, however less commonly, for an ovarian cyst to be malignant. A perineural cyst is a fluid-filled sac that forms on the spine. High levels of oestrogens in an ovarian cyst are indicative of a follicular origin. These pathological cysts do not go away and may require surgical removal. One follow-up study 16 of 389 women who underwent cyst aspiration found that 44 women had a recurrent cyst and 20 had a solid mass at the aspiration site. Identification of the nature of the cystic lesion, especially in the differentiation of benign and malignant processes. Investigation of cystic lesions at various sites to determine the nature of the underlying process. Endometriomas Cysts: Endometriomas is one of the most common pathological types of cyst that develops as a result of a condition, called- endometriosis. Microscopic examination of Papanicolaou and Romanowsky stained cellular component of smears and/or centrifuged fluid measurement of oestrogen levels in ovarian cyst fluids. Also, unlike functional cysts, pathological cysts do not shrink/dissolve naturally and almost always require surgical removal (ovarian cystectomy). Refrigerate or add equal volume of 50% ethanol to the fluid if more than 24hr delay to laboratory.Ĭlinical information may be essential for interpretation of some conditions. The term CMN is sometimes replaced by cystic medial degeneration, as necrosis is not always present in the pathological process and the latter can be. Optional wet fixed (95% ethanol) and/or air dried direct smears may be made at the time of aspiration. Cyst fluid from various sites (eg, thyroid, ovary, breast) should be sent to the laboratory as soon as possible after aspiration.
