Malignant struma ovarii is extremely rare in the clinic. The diagnosis and modalities of treatment are still controversial. Here we describe a case of extensive peritoneal implant metastasis originating from malignant struma ovarii discovered 14 years after ovariectomy and chemotherapy. ⋯ Therefore, thyroidectomy followed by adjuvant I treatment should be recommended in patients with malignant struma ovarii as metastatic risk is difficult to predict based on histopathologic examination.

Migraine is a relatively common disease that is associated with high disability and reduced quality-of-life. This study aimed to investigate the prevalence, epidemiological characteristics, and risk factors of migraine in Han Chinese from Fujian Province, China. A cross-sectional epidemiological survey study was conducted to evaluate characteristics of migraine in Han Chinese. ⋯ Multivariate regression analysis showed that the odds of migraine were significantly lower in subjects aged ≥50 years compared with those aged <30 years (odds ratio [OR] ranged from 0.40 to 0.64; P ≤.013) and was higher in females compared with males (OR = 2.89, P <.001). The odds of migraine was significantly greater in subjects with a history of alcohol consumption (OR = 1.81, P <.00) and insomnia (OR = 2.77, P <.001). Han Chinese in Fujian province has a relatively high prevalence of migraine, and female gender, <50 years of age, insomnia, and use of alcohol are associated with increased odds of having migraine in this population.

Calcifying fibrous tumors ("CFT") are recognized as extremely rare mesenchymal tumors with benign biological behavior and low rates of recurrence are seen after removal. The first case of a CFT was reported in 1988 as a possibly inflammatory triggered pseudotumor in deep soft tissue of children. Histologically, the tumor is typically composed of dense hyalinized collagen with paucicellular infiltration of lymphocytes and fibroblasts as well as psammomatous or dystrophic calcifications. It can affect soft tissue in very different anatomical locations, also intrathoracic and intra-abdominal, mimicking various different diagnoses. The etiology is understood to be unclear. Asymptomatic CFTs can be found incidentally on medical images. ⋯ We add another case of intra-abdominal CFT to medical literature to provide more information about this very seldom tumor. While the etiology of CFT should be further investigated, diagnosis and therapy seem clarified. CFT should be kept in mind as a rare differential diagnosis of calcifying tumors also in the abdominal cavity. Immunohistological work-up is important for finding the diagnosis and may also help solving pathogenetical questions.

Tumor-induced osteomalacia (TIO) is a rare, paraneoplastic syndrome featured with fibroblast growth factor 23 (FGF23) secretion primarily by benign mesenchymal tumors and sometimes by malignancies. TIO diagnosis and treatment is often delayed because TIO usually has nonspecific generalized bone pain and weakness, and location of TIO tumor is quite challenging. Very few TIO caused by sinonasal hemangiopericytoma have been reported in the literature. ⋯ By presenting this case, we hope to remind clinicians that in patients with osteomalacia with undetermined reason and intranasal polypoid mass, sinonasal hemangiopericytoma should be suspected.

Red man syndrome (RMS) is the most common allergic reaction to vancomycin. It generally occurs during rapid infusion of vancomycin; only few cases have been reported as results of local vancomycin administration. We hereby report a rare case where RMS developed after insertion of vancomycin-loaded bone cement in a primary total knee replacement (TKR). ⋯ Vancomycin-induced RMS may occur after the routine use of vancomycin-loaded bone cement in the primary TKR replacement.
