Angiomyxolipoma is a recently described and rare variant of lipoma that is characterized by the proliferation of adipose tissue with a myxoid stroma and multiple thick and thin-walled blood vessels. A 51-year-old man presented with a tender subcutaneous nodule on his right arm. The tumor was completely removed by excisional biopsy, and the histopathologic features revealed a thin fibrous capsule with incomplete fibrous septa extending into the lesion, dividing it into lobules of different sizes. The fat cells were mature, with a single vacuole and an eccentric nucleus. The vascular component consisted of groups of capillaries and occasional vessels of larger caliber. Erythrocytes were present within the lumen, and myxoid stroma was found. He was diagnosed as having angiomyxolipoma. Herein, we report a rare case of subcutaneous angiomyxolipoma of the arm. We also review and discuss such cases in the literature.

Purpureocillium lilacinum, formerly Paecilomyces lilacinus, is a saprophytic fungus found in soil and rotting vegetation and rarely pathogenic to humans. Only 4 cases of cutaneous infection caused by Purpureocillium lilacinum have been reported in the name of Paecilomyces lilacinus. Herein, we report a case of localized cutaneous infection due to Purpureocillium lilacinum. A healthy 81-year-old immunocompetent male presented with an erythematous scaly and pustular plaque on his left dorsal hand that had begun 3 months ago. Histopathologic examination showed suppurative granulomatous inflammation with hyphae and round spores in the dermis. Periodic acid-Schiff and methenamine silver stain revealed fungal spores. Fungus culture from the biopsy specimen revealed velvety pink to white colonies after 15 day-incubation period. The slide culture stained with lactophenol-cotton blue showed typical long hyphae and flask-shaped phialides with oval conidia in chains. The result of DNA sequencing from the colony was identical to that of Purpureocillium lilacinum.

OSCC is currently the most common malignancy of the head and neck, affecting tens of thousands of patients per year worldwide. Natural flavonoids from plants are potential sources for novel anti-cancer drugs. Icariin is the active ingredient of flavonol glycoside, which is derived from the medical plant Herba Epimedii. A metabolite of icariin, icariside II exhibits a variety of pharmacological actions, including anti-rheumatic, anti-depressant, cardiovascular protective, and immunomodulatory functions. However, the exact mechanism causing the apoptosis-inducing effect of icariside II in OSCC is still not fully understood. In the present study, we assessed the anti-cancer effect of icariside II in OSCC cell lines by measuring its effect on cell viability, cell proliferation, and mitochondria membrane potential (MMP). Icariside II treatment of OSCC cells resulted in a dose- and time-dependent decrease in cell viability. Hoechst staining indicated apoptosis in icariside II-treated HSC cells. Icariside II inhibited cell proliferation and induced apoptosis in HSC cells, with significant increases in all present parameters in HSC-4 cells. The results clearly suggested that icariside II induced apoptosis via activation of intrinsic pathways and caspase cascades in HSC-4 cell lines. The collective findings of the study suggested that Icariside II is a potential treatment for OSCC; in addition, the data could provide a basis for the development of a novel anti-cancer strategy.
