Description
Nan Huang and coauthors present in 2026 a case of a rare skin hamartoma found in an unusual place on a teenager's knee. The condition, nevus lipomatosus cutaneous superficialis, places mature fat tissue inside the upper skin layer. It usually appears on the buttock or thigh, not near the knee.
A 15-year-old boy had a lump below his left knee for five years, with small bumps across its surface. Microscope study showed the misplaced fat plus storiform masses of spindle cells and mast cells, and staining marked those cells positive for CD10. Naming the added growth pattern helps doctors recognize this rare mix earlier.
