Ectopic omental deciduosis associated with pregnancy

Ectopic decidua (deciduosis) is most commonly localized in the ovary, uterus, cervix, and tuba uterina. It can rarely be observed within the peritoneum in pregnant women during laparotomy. More rarely, it can be localized in the omentum, appendix, liver, and spleen. It is usually incidental. In a 23-year-old female patient, a biopsy was taken from the thickening in a 4x3 cm area on the omentum during cesarean section. Microscopic evaluation revealed decidualized cells the majority of which had large polygonal eosinophilic cytoplasm and a few of which had vacuolated cytoplasm, that formed small nodules in the adipose tissue. Immunohistochemically, the decidualized cells were positive for vimentin, progesterone receptor antibody and negative for S-100, HMB-45, calretinin, pancytokeratin. The case was reported as ectopic omental deciduosis. Although ectopic omental deciduosis is a benign lesion, it may be confused with malignant tumors. Therefore, differential diagnosis should be made carefully. [Med-Science 2020; 9(4.000): 1093-6

Osteoid Osteoma of the Trapezium: Case Report

Osteoid osteoma is a benign bone tumor representing approximately 10% of all benign bone tumors. Although osteoid osteoma of the long bones and carpus is frequent, the location in the trapezium is extremely rare. We found only one other report in the literature regarding osteoid osteoma of the trapezium. (J Hand Surg 2010;35A:636-638.

A rare large mutation involving two exons of the SP-B gene in an infant with severe respiratory distress

Hereditary surfactant protein-B (SP-B) deficiency is a rare autosomal recessive disease of newborn infants causing severe respiratory failure and death within the first year of life. The most common cause of SP-B deficiency is a frameshift mutation in exon 4 (121ins2) in the gene encoding SP-B. We report a term infant with unremitting respiratory distress who was unresponsive to all treatment modalities. The parents were consanguineous and a term sibling of the infant had died due to respiratory failure without a certain diagnosis. In the first step of the diagnostic work-up, common genetic mutations for SP-B, surfactant protein C and ATP-binding cassette s3 were absent, however sequencing of SP-B gene revealed a large homozygous genomic deletion covering exon 8 and 9. In this case report, we aimed to emphasize further genetic evaluation in all cases suggestive of surfactant dysfunction, even if common mutations are absent

A Rare Cause of Pericardial Effusion: Giant Cell Arteritis

Giant cell arteritis is a granulomatous vasculitis characterized by medium or large sized vessel involvement. Although extracranial branches of the carotid artery are typically involved, involvement of aorta and its major branches can also be seen. Cardiac involvement has been encountered less frequently and pericardial effusion is rarely encountered. In this paper, a case has been presented in which pericardial effusion was determined during the examination and diagnosis was giant cell arteritis
