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.

The author has experienced a case of microphthalmos with large orbital cyst in a 4 months old female, that was found at the time of birth. To facilitate fitting a cosmetic prosthesis, the microphthalmos with cyst was removed surgically. On serial section I could find an area of discontinuation of the sclera that was suspected to be the defective closure of the embryonic cleft. Some aberrant retinal tissue was found in the wall of the cyst, and markedly disorganized ocular tissue forming a tumor-like mass filled the microphthalmic eyeball. In view of these histopathologic findings I could draw the conclusion that developmental failure of the embryonic eyeball and consequential proliferation of the embryonic neuroepithelial cells occurred at an early developmental stage causing the formation of microphthalmos with cyst.

An unusual localization of localized colitis cystica profunda in a 31-year-old man is described. The patient presented as anal bleeding and a protruding mass at the descending colon; the mass was polypoid and was made up of papillary epithelial hyperplasia with downward herniation of glands into the submucosa. Only one similar case involving a descending colon has been reported in the world literature.

A 24-year-old lady with recurrent upper abdominal pain, underwent surgery for cholelithiasis based on imaging diagnosis by ultrasound scanning. At laparotomy, the gall bladder could not be found either in its normal or ectopic locations. The diagnosis of agenesis of the gall bladder was confirmed by operative cholangiography. Duplication cysts of the hepatic flexure were discovered in the position normally occupied by the gall bladder. The stony hard faeces in the cysts were probably interpreted as gallstones on ultrasound. This rare condition is discussed and the importance of intraoperative cholangiography is stressed.

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.

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.

Gastritis cystica profunda (GCP) is a rare disease which shows multiple cystic gastric glands within the submucosa of the stomach. GCP lesions mainly develop at the site of gastroenterostomy and exhibit benign behavior. However, there have been a number of debates over its malignant potential. Several reports have documented GCP accompanied by gastric carcinomas, but the relationship between the two conditions remains uncertain. Here we report two cases of GCP with dysplasia accompanied by synchronous multiple early gastric cancers without previous gastric surgery.
