A 63-year-old man who underwent insertion of a lumboperitoneal shunt developed gait disturbance. He had undergone surgery for gastric cancer 7 years and for ileus 5 years previously. Head computed tomography (CT) revealed enlargement of the ventricles. Abdominal CT revealed a cyst in the abdominal region and the distal segment of the peritoneal shunt tube located within the cyst. Laparotomy rev...

Nasolabial cyst is a rare nonodontogenics, soft-tissue cyst occurring in the sublabial area and anterior maxillary region. The patient usually presents with a slowly enlarging asymptomatic swelling. They are usually diagnosed in early stages because of cosmetic problems. In our paper we report a nasolabial cyst of a 53-year-old man and discuss the diagnosis, differential diagnosis, and treatmen...

Dermoid cysts of the head and neck are rare lesions. An unusual dermoid cyst in the subcutaneous tissue of the mastoid region is easily confused with lymph node abnormalities; therefore, diagnosis and treatment are often challenging. We describe a 22-year-old male with an unusual dermoid cyst in the subcutaneous tissue of the mastoid region whose only complaint was a retroauricular lump, which ...

Choroid plexus cysts are rare lesions in the brain and are reported in humans and dogs. Herein, we report a choroid plexus cyst found in a 10-week-old female Sprague-Dawley rat. Histologically, a cyst measuring approximately 600 μm in diameter was found in the fourth ventricle of the brain. The cyst was lined with a single layer of flattened cells and was present in the connective tissue of the...

The simple bone cyst, as newly classified by WHO in 2005, is a lesion related to the jawbones. Therefore, it is not a cyst, since it is a cavity devoid of epithelial tissue. It is a rare pathology affecting the mandible more than the maxilla. Its onset occurs mainly during the first two decades of life, irrespective of sex. The purpose of our report is to exhibit the particular case of a 17-yea...

An unusual case of saphenous neuropathy secondary to compression by a large hydatid cyst within the adductor longus muscle is reported. Solitary hydatid cyst(s) localized in the skeletal muscles occur rarely and often mimic soft tissue tumours. Presentation with signs of peripheral nerve compression by a hydatid cyst in an extremity is exceedingly rare. Diagnosis can be established by ultrasoun...

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...

An 8-year-old intact rabbit was presented to a veterinary hospital with a complaint of enlarged left scrotum. Histological examination revealed a single large cyst adjacent to an efferent ductule-like tissue. The cyst wall was composed of monolayer cuboidal cells surrounded by dysplastic testicular tissue, and the seminiferous tubules were not developed at all. The epithelial cells of the cyst ...

INTRODUCTION Soft tissue mass following total hip arthroplasty raises several differential diagnoses not limited to infection, hematoma, wear debris, malignancy, and bursitis. Rice body formation in the hip region is an uncommon process denoting a chronic inflammation. We report here the second case of its kind in the medical literature of a wide symptomatic rice-like body cyst complicating a t...
