A Case of Metastatic Basal Cell Carcinoma Treated with Cisplatin and Adriamycin.

A 72-year-old man was referred to our hospital for treatment of an ulcer that had been growing on his back for 10 years. Physical examination showed an ulcerated tumor from the neck to the back and swollen cervical lymph nodes. The tumor size was 12×9 cm.

Extranodal Natural Killer/T-Cell Lymphoma, Nasal Type, with Primary Manifestation as an Upper Eyelid Swelling.

Extranodal natural killer/T-cell lymphoma (ENK/TCL) is most often in the nose or the nasopharynx but can present elsewhere. We report a rare case of ENK/TCL that presented as swelling of an upper eyelid without ocular involvement. A 76-year-old man visited our hospital with a swollen lesion of the left upper eyelid which had appeared 2 months earlier.

Insulin-like growth factor 2 mRNA-binding protein-3 as a marker for distinguishing between cutaneous squamous cell carcinoma and keratoacanthoma.

In the histopathological diagnosis of cutaneous tumors, the differential diagnosis of squamous cell carcinoma (SCC) with crateriform architecture and keratoacanthoma (KA) is often difficult so an accurate understanding of the biological features and the identification of reliable markers of SCC and KA are crucial issues. Insulin-like growth factor 2 mRNA-binding protein-3 (IGF2BP3, also known as IMP3) is thought of as a bona fide oncofetal protein, which is overexpressed and is involved in cell proliferation, migration, and invasion in several kinds of tumors. However, the role of IMP3 in cutaneous SCC and KA has not been well studied.
