Sarcoidosis is a systemic granulomatous disease of unknown cause that commonly involves the lungs, lymph nodes, bones, liver, spleen, or skin. Cutaneous findings of sarcoidosis occur in 20% to 35% of patients with systemic disease. The recognition of cutaneous lesions is important, because it gives important clues to diagnosis and also allows for easy biopsy. We report a 71-year-old Turkish woman with erythematous lesions, which included widespread, erythematous macules of various sizes on the chest, abdomen, and back on both sides of her body. Fine white scales covered some of the lesions. Hepatomegaly and bilateral hilar lymphadenopathy were also observed. Biopsy specimens of the skin showed dermal, noncaseating, epitheloid granulomas. The diagnosis, based on correlation of the clinical presentation and histopathological findings, was ichthyosiform sarcoidosis with systemic involvement. The difference between our case and other cases of ichthyosiform sarcoidosis described in the literature is that ours involved only the trunk and not the extremities. We are presenting this case because it is an interesting and rare variant of ichthyosiform sarcoidosis.

The present study was designed to investigate the protective effects of L-carnitine (LC) on changes in the levels of lipid peroxidation and endogenous antioxidants induced by cisplatin (cis-diamminedichloroplatinum II, CDDP) in the liver and kidney tissues of rats. Twenty-four Sprague Dawley rats were equally divided into four groups of six rats each: control, cisplatin, L-carnitine, and L-carnitine plus cisplatin. The degree of protection produced by L-carnitine was evaluated by determining the level of malondialdehyde (MDA). The activity of glutathione (GSH), glutathione peroxidase (GSH-Px), glutathione S-transferase (GST), and superoxide dismutase (SOD) were estimated from liver and kidney homogenates, and the liver and kidney were histologically examined as well. L-carnitine elicited significant liver and kidney protective activity by decreasing the level of lipid peroxidation (MDA) and elevating the activity of GSH, GSHPx, GST, and SOD. Furthermore, these biochemical observations were supported by histological findings. In conclusion, the present study indicates a significant role for reactive oxygen species (ROS) and their relation to liver and kidney dysfunction, and points to the therapeutic potential of LC in CDDP-induced liver and kidney toxicity.
