Sorghum is the fifth most important cereal in the world as one of the staple food. For the use of natural dye, we have done some researches about sorghum red pigments extracted from stalk and leaves on its physiochemical properties, extracting methods and applications. The researches involved maximum extraction of sorghum pigment and analysis of its processing condition. Total polyphenol and tannin contents were measured by varieties and different plant parts. The stabilities of pigment by irradiation and heat treatment for processing were measured by colorimeter and thermal gravimetric analysis (TGA). In addition, hybrid nano-silica composites with sorghum pigment were made by combining with polyvinyl alcohol, polyvinyl acetate and sodium silicate. Water silica hybrids with sorghum pigment were performed by emulsion treatment. Nano-silica particles were identified and measured their size to be about 200 ~ 400 nm by SEM analysis.

Skin metastasis in patients with ovarian cancer is quite uncommon. Most cases reported to date involved the trunk, sparing the extremities. We report the case of a 60-year-old woman with a subcutaneous nodular lesion on her left thigh, which was diagnosed as skin metastasis of ovarian serous papillary adenocarcinoma. She first noticed the nodule 42 months after her initial diagnosis of ovarian cancer. The diagnosis of the lesion was a challenge, as it morphologically mimicked a benign lesion such as a lipoma or epidermal cyst. Despite multiple sessions of chemotherapy, she died 3 months after being diagnosed with skin metastasis. Together with a concise review of the literature, we report an uncommon case of skin metastasis in a patient with ovarian cancer. (Korean J Dermatol 2018;56(2):130∼134)

Pigmented dermatofibrosarcoma protuberans (Bednar tumor) is an uncommon variant of dermatofibrosarcoma protuberans. Well-known for its high local recurrence rate and possible systemic metastasis, early detection and treatment of this rare variant is critical. Here we report the case of a 45-year-old Korean woman without particular medical history who presented with a faint blue macule on her chest. Suspicion of a tumorous condition was quite low, until histopathological and immunohistochemical findings led to the diagnosis of pigmented dermatofibrosarcoma protuberans. Microscopic findings consisted of proliferations of spindle-shaped cells in the lower dermis. Additionally, clumps of melanin pigments were observed within the tumor cells. The few cases of pigmented dermatofibrosarcoma protuberans that have been reported thus far address variable clinical characteristics of this neoplasm. However, the majority of the cases were pediatric, and the macroscopic appearances were evidently suggestive of a cutaneous neoplasm. As the first Korean adult-onset case of pigmented dermatofibrosarcoma protuberans, this peculiar case illustrates the possible benign macroscopic feature of pigmented dermatofibrosarcoma protuberans, which could have been overlooked.
