[Sialic acid concentrations in blood samples as well as in cyst and peritoneal fluid in patients with ovarian cysts and cystic ovarian tumors].

It should be solved the question if the estimation of the TSA-concentrations in various body fluids of patients with ovarian tumour like conditions (n = 11), and benign (n = 28) and malignant (n = 25) cystic ovarian tumours can be used as a tumour marker with an additional clinical information. The determination of the concentrations were carried out in blood sera, cyst and peritoneal fluids. The periodate-thiobarbituric acid-assay was used to measure the TSA-contents. The sensitivity of pre-therapy TSA-concentrations in serum for malignant cystic ovarian tumours is 0.59 at a prevalence of 0.55; the specificity has a value of 0.79. There is no improvement of clinical validity through a pre-therapy TSA/total protein (TP)-ratio in serum (sensitivity 0.41; specificity 0.71). There are no useful clinical data of simultaneous estimation in serum, tumour cystic and peritoneal fluids of the same patient.

[Prostatic utricle cysts (Müllerian duct cysts) (author's transl)].

Authors report two cases of prostatic utricle cysts, one of which was operated. They collect from literature 20 other cases in children aged ten years or less. Natural history of patients is reported. They also comment on the symptoms and associated anomalies and conclude discussing diagnostic and operative procedures available in these patients.

[The x-ray picture of cysts and cyst-like neoplasms of the mandible].

A total of 444 patients with histologically verified cysts (radicular, residual, traumatic, keratocysts, follicular) and some cystic formations (ameloblastomas, osteoclastomas, myxomas) were examined by clinical and x-ray methods. X-ray signs of some cystic diseases of the mandible are analyzed, x-ray symptoms which help differentiate between individual nosologic entities are singled out.

Calcifying odontogenic cyst immunohistochemical detection of keratin and involucrin in cyst wall.

Calcifying odontogenic cysts (COC) were immunohistochemically described using different keratin proteins and involucrin as well as histopathology. The cystic lining epithelium was composed of calcifying, keratinizing, squamous, and columnar epithelial cells, and included calcified masses of irregular shape and various size as well as ghost cells. Calcifying epithelium gave negative or only trace staining for keratins detected with low molecular keratin (PKK1), but were regularly positive with high molecular keratin (KL1) and polyclonal antibody for keratin (TK). They were occasionally positive for involucrin. The cells located in the periphery of the calcified masses had a particular abundance of high molecular weight and total keratins (KL1 and TK). Calcified bodies and ghost cells were devoid of any immunoreactivity. Squamous epithelium was relatively similar to that of normal squamous cell epithelium in the oral mucosa. It were most commonly found in columnar cystic epithelial cells which displayed intense staining with all immunoreagents. It is postulated that such epithelial cells may have a strong potentiality to transform into ghost cells or to undergo metaplasia. They may develop altered synthesis of homogenous acellular materials and finally become transformed into calcifying epithelium containing dystrophic calcified masses.

Hydatid cyst of the pulmonary artery secondary to hepatic hydatid cyst embolism.

A cystic lesion of the liver extending into the inferior vena cava was discovered in a 33-year old female patient suffering from dyspnea, pain and swelling in the legs. Plain chest X-ray was normal. CT and MRI of the thorax showed a cystic lesion within the right pulmonary artery. The liver lesion was treated by a partial cystectomy and omentoplasty, inferior vena cava and bile ducts repair. Through a right thoracotomy, a hydatid cyst was found in the pulmonary artery and enucleated. Although very rare, pulmonary artery hydatidosis may be the cause of an unexplained dyspnea in patients with hydatidosis of the liver.

The keratinizing and calcifying odontogenic cyst (Gorlin cyst).

A 61-year-old white woman had a radiolucent lesion in the anterior portion of the mandible which was diagnosed as a keratinizing and calcifying odontogenic cyst. As it has a radiographic appearance similar to other pathologic processes, it should be considered in the differential diagnosis when a radiolucent-radiopaque lesion is encountered.

Peripheral calcifying odontogenic cyst (Gorlin cyst).

A case report of a rare peripheral calcifying odontogenic cyst is presented. The clinical, radiographic and histopathologic features of the lesion are discussed, along with the etiology, rate of occurrence and diagnosis.
