Computed tomography findings of primary serous papillary carcinoma of the peritoneum in women

With the aim to describe preoperative computed tomography (CT) findings, the clinical, histopathological, and CT findings of the 12 consecutive patients with a confirmed diagnosis of primary peritoneal serous papillary carcinoma (PPSPC) were retrospectively evaluated. Of the 12 patients with a mean age of 57.5 +/- 10.3 years, ten (83.3%) were postmenopausal. Serum Ca-125 levels were elevated in all patients. Ten (83.3%) had Stage III and two (16.7%) patients had Stage IV disease and none of the excised ovaries had deep parenchymal involvement. The most common CT findings were the omental (n = 11), mesenterial (n = 11) and parietal peritoneal involvements (n = 10), and variable amount of ascites (n = 10). Pelvic peritoneal involvement in four (33.3%) patients was so extensive that it resembled a mass in the Douglas pouch. Thickening of the wall of gastrointestinal viscera (n = 9), lymphadenopathy (n = 5) and pleural effusion (n = 5) were the other CT findings and calcification was seen in only three (25.0%) patients. Although, none of them was characteristic, CT features of diffuse peritoneal, omental and mesenterial involvement especially in middle-aged or elderly postmenopausal women with normal-size ovaries in the absence of an identifiable primary site in conjunction with elevated level of serum CA-125 should suggest the possibility of PPSPC.

Calciphylaxis in a patient with rheumatoid arthritis without renal failure and hyperparathyroidism: the possible role of long-term steroid use and protein S deficiency

Calciphylaxis is a rare and life-threatening condition of progressive cutaneous necrosis secondary to small and medium-sized vessel calcification that is seen almost exclusively in patients with end-stage renal disease and hyperparathyroidism. We report a case of calciphylaxis that may very well be due to a long-term steroid use in a rheumatoid arthritis patient who had neither end-stage renal disease nor hyperparathyroidism. We also discuss the possible role of protein S deficiency as a contributing factor.
