We report a case of hemophilic pseudotumor in the ulna of a 6-year-old boy treated with radiation therapy. A total dose of 900 cGy in 6 fractions was given in 6 consecutive days. Progression of cystic changes was halted within a month. New bone formation and trabeculation were found on the 4th month. Complete healing of the lesion and bony replacement were found on the 12th month. The patient was followed up to 72 months and there was no evidence of recurrence and no bone growth disturbance. Radiation therapy can be an effective alternative modality in treating hemophilic pseudotumor.

A duodenal duplication cyst is an uncommon congenital anomaly that is usually encountered during infancy or in early childhood. Duodenal duplication cysts generally appear on the first or second portion of the duodenum and may cause duodenal obstruction, hemorrhage or pancreatitis. Here, we report a case of a duodenal duplication cyst on the second and third portion of the duodenum in an old aged man with obstructive jaundice and acute pancreatitis, which was treated successfully by a surgical excision.

OBJECTIVE: To investigate the pathogenesis of nasal vestibular cyst. METHOD: Forty two case of nasal vestibular cyst were retrospectively analyzed, including clinical manifestation, pathological findings, surgical therapy efficacy. RESULT: Of these 42 cases of the type of lining epithelia, pseudostratified columnar epithelium was identified in 24 cases, stratified squamous epithelium in five cases, simple cuboidal epithelium in five cases, and two kinds of above mentioned epithelia in eight cases. Goblet cells were present in 23 cases. Surgical excision was performed via the labiogingival groove approach for all patients. The duration of follow-up ranged from 6 months to 10 years. No postoperative recurrences were found. CONCLUSION The abnormal development of nasolacrimal duct systems may take an important role in the pathogenesis of nasal vestibular cyst. According to this, we considered the total excision via the sublabial approach is more reasonable surgery than endoscopic marsupialization, but it is need further observation.

Giant cell tumors are distinctive neoplasms characterized by a profusion of multinucleate giant cells scattered throughout a stroma of mononuclear cells. Most giant cell tumors are found at the epiphyses of long bones, especially around the knee joint. Flat bone involvement is rare. However, a case of giant cell tumor with secondary aneurysmal bone cyst was encountered at the scapula of a 25-year-old man. Since the occurrence of a giant cell tumor with secondary aneurysmal bone cyst on flat bones (i.e., the scapula) is extremely rare, the above-mentioned case is worthy of reporting.

We report the case of a 52-year-old woman who developed vertical diplopia of 1-days duration. Neuro-ophthalmological testing revealed left trochlear nerve palsy, and sellar MRI revealed a 1.5 cm-sized pituitary mass lesion, a Rathke's cleft cyst. The diplopia disappeared spontaneously after 6 days.

INTRODUCTIONThis report describes a "parasitic" endometriotic cyst of the small bowel.

CLINICAL PICTUREA menopausal woman with a pelvic mass presenting years after commencing hormone therapy.

TREATMENTWe performed laparoscopic excision of a cystic tumour attached to the small bowel with a solitary vascular pedicle.

OUTCOMEHistology confirmed it to be an endometriotic cyst of ovarian origin, probably resulting from spillage during previous surgery and reactivation with hormone therapy.

CONCLUSIONSWe discuss the possible aetiology of this unusual presentation of endometriosis and review the literature on parasitic gynaecological tumours.

OBJECTIVETo investigate the treatment of cystis vesicular seminalis induced by the obstruction of the distal end of the ejaculatory duct.

METHODSFrom November 2005 to December 2006,12 cases of cystis vesicular seminalis ( [2.3 +/- 1.1] cm) were diagnosed by semen analysis (as on the seminal volume, pH and fructose), transrectal palpation and ultrasonography. All cases were treated by transurethral incision or resection of the obstructive ejaculatory duct till milky semen discharged.

RESULTSThe cysts were significantly reduced ([1.0 +/- 0.8] cm, P < 0.05) in all the 12 cases and no complications were observed during the follow-up 1, 3 and 12 months later.

CONCLUSIONTransurethral electrotomy is a simple and effective method for the treatment of cystis vesicular seminalis induced by the obstruction of the ejaculatory duct.

PURPOSE: To report a case of conjunctival inclusion cysts on the corneal limbus of a patient with chronic vernal keratoconjunctivitis during 16 months' follow up. METHODS: The patient was a 26 year old male without any specific history of surgery or trauma. Giant papillae, shield ulcers, and Horner-Trantas dots were detected. During the 16 month follow-up, Sodium cromoglycate eye drops and Prednisolone acetate 1% eye drops were given 3 times a day. During this period, conjunctival cysts were detected on the corneal limbus in both eyes. In spite of improvement of the corneal and conjunctival conditions, the conjunctival cysts did not seem to show any specific changes. For relief of foreign body sensation, excision of the conjunctival cysts and giant papillae of the left eye and histopathologic examination of the specimen was performed. RESULTS: On histopathological examination, the conjunctival cysts consisted of nonkeratinizing stratified epithelial cells filled with PAS-positive mucous substance. Inflammatory cells were not found in the vicinity. CONCLUSIONS: Conjunctival inclusion cysts can be seen as an atypical finding of long-standing vernal keratoconjunctivitis. Mechanical friction between the giant papillae and conjunctiva may be a factor in inducing the formation of the conjunctival cysts.
