BACKGROUND Several techniques have been described in liver hydatid disease surgery, with most well known partial cystectomy, capitonage and introflexion. METHODS We present a technical modification on open partial cystectomy for liver hydatid disease. We performed this operation in 2 patients with liver echinococcosis. The cyst is being unroofed and evacuated from the daughter cysts. The iden...

The genome of the protozoan parasite Giardia lamblia is organized in two diploid nuclei, which has so far precluded complete analysis of gene function. Here we use a previously developed Cre/loxP-based knock-out and selection marker salvage strategy in the human-derived isolate WB-C6 to eliminate all four copies of the Cyst-Wall-Protein-1 locus (CWP1). Because these loci are silenced in prolife...

CONTEXT Enteric duplication cysts are rare lesions of uncertain incidence and natural history. Pre-operative confirmation of diagnosis can be difficult. This case reports an adult duodenal duplication cyst presenting with grossly elevated intra-lesional levels of tumour markers. CASE REPORT A 57-year-old female was found to have a complex cystic lesion of the head of the pancreas. Intra-lesio...

Toxoplasma gondii is an obligate intracellular parasite that can invade any nucleated cell of warm-blooded animals. During infection, T. gondii disseminates as a fast replicating form called the tachyzoite. Tachyzoites convert into a slow-growing encysted form called the bradyzoite by a signaling process that is not well characterized. Within animals, bradyzoite cysts are found in the central n...

CONTEXT In the last years, cystic pancreatic lesions are often detected when clinically silent, because of the wider use of diagnostic imaging techniques. First described by Othman in 2007, "squamoid cyst of pancreatic ducts" represents a cystic dilation of ducts, lined by non-keratinized squamous epithelium. We report the first case of squamoid cyst of pancreatic ducts in Italy. CASE REPORT ...

Diagnosis: Congenital Bronchogenic Cyst The roentgenogram of the chest (Fig 1) demonstrates a large, oblique, homogeneous shadow with a sharp border in the right lower lobe. No calcifica-tion is seen within the lesion. Thoracotomy revealed a 3x5x2 cm thick-walled cystic mass filled with mucoid material deep within the right lower lobe. It showed no abnormal bronchial communication and had no sy...

UNLABELLED We report the case of a 39-year-old female with primary vaginal squamous cell carcinoma arising from a squamous inclusion cyst of the posterior wall. The tumor was located in the vaginal wall and extended into the rectovaginal septum. The overlying mucosa was intact. Histologically, there was invagination of the surface squamous vaginal epithelium forming a cystic lesion. In some are...

Ectopic adrenal tissue is a relatively common finding, especially in children. The most common localization is the male genital system, especially the spermatic cord. Female genital tract is also a common site for ectopic adrenal tissue but, ovarian localization is very rare. A 21-year-old woman presented with complaints of abdominal swelling, pelvic pain and menstrual irregularity. Ultrasonogr...

Postoperative maxillary cyst is a quite rare delayed complication of surgical intervention associated with maxillary sinuses. It occurs many years after surgery. This paper describes a 54-year-old woman presenting with swelling of left cheek for seven-years duration. The orthopantomograph revealed a unilocular cystic radiolucency with well-defined margins in left maxillary sinus. In the compute...

A 67 year-old male consulted our department for examination a painless left scrotal mass accompanied by a continuously high serum carbohydrate antigen 19-9 level (CA19-9, 563.2 IU/ml). The patient underwent radical orchiectomy oof the mass. The histopathological diagnosis was an organized hematocele, and left testicular tissue was found in the cyst wall. There was no evidence of malignancy in t...
