Article Synopsis
- A 75-year-old man with a history of transverse colon cancer surgery presented with retroperitoneal fibrosis (RPF) detected during a routine CT scan, prompting concerns about cancer recurrence or IgG4-related disease (RD).
- Despite normal tumor markers and IgG4 levels, his soluble interleukin 2 receptor (sIL-2R) levels were elevated, indicating unusual immune activity.
- Ultimately, an open biopsy confirmed the presence of IgG4-positive plasma cells, leading to a diagnosis of IgG4-RD RPF, suggesting that elevated sIL-2R and imaging characteristics can help in identifying this condition after colorectal cancer surgery.
Background/purpose: Early detection and proper excision of the primary lesions of melanoma are crucial for reducing melanoma-related deaths. To support the early detection of melanoma, automated melanoma-screening systems have been extensively studied and developed. In this article, a previously reported hyperspectral imager and melanoma discrimination index are applied to the discrimination of acral lentiginous melanoma (ALM) from acral nevus (AN), and their diagnostic performance is reported.

To support the early detection of melanoma, automated melanoma screening systems have been extensively studied and developed. In this article, we present a hyperspectral melanoma screening system and propose a possible melanoma discrimination index derived from the characteristics of the pigment molecules in the skin, both of which have been derived from hyperspectral data (HSD).
