We present a case of giant calcifying epithelioma of Malherbe (pilomatrixoma) in the right upper arm of a 62-year-old man. It measured 18 x 12 x 8 cm in size, making it the largest of all the cases reported previously. CT clearly demonstrated a well-defined, subcutaneous mass with amorphous calcifications. The mass showed intermediate signal intensity on T2*-weighted MR images and slight contrast uptake on contrast-enhanced MR images. Histopathologically, this tumor showed no aggressive or malignant nature. The patient is without evidence of recurrence or metastasis 3 years following the resection.
In order to evaluate clinical efficacy of D-penicillamine (DP) a double-blind study was conducted by the Metalcaptase Research Croup consisting of forty-one rheumatological centers in Japan. A total of 179 patients with rheumatoid arthritis (RA) was divided into two groups; one treated with 5 mg (control group) and the other with 100 mg (drug group) of DP in capsule form. The trial lasted 24 weeks. Global judgment by physicians revealed that improvement was found in 27% in the controls and 65% in the drug group. Adverse reactions occurred in 34% of the controls and 49% of the drug group. Skin rashes, taste disturbances, gastrointestinal upset and proteinuria were frequent in the drug group, but severe or fatal reactions could not be seen in this trial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
