Description
Prajakta Sharma, Rishabh Singhal, and Balkrishna Nikam present, in 2026, a quiz case of a slow lump under a man's thumbnail. The 67-year-old had the painless growth for five years, with a thick, eroded nail plate. Fungus drugs had failed to help. A small tissue cut gave the answer under the microscope.
The tumour proved to be eccrine porocarcinoma, a rare sweat gland cancer. It made up far less than one percent of skin cancers, and nail cases are rarer still. The slides showed islands of small uniform cells with ducts, plus some odd large cells. The authors note only a few like cases on record. The case warns doctors to biopsy stubborn nail lumps.
