Primary Cutaneous B-Cell Lymphoma and Lymphoproliferative Disorders of Skin
Bibliographic record
Abstract
Cutaneous B-cell lymphomas (CBCLs) are rare and are usually secondary to systemic nodal lymphoma. These lymphomas account for about 20% of all cutaneous lymphomas. Only recently has the existence of B-cell lymphoma presenting clinically in the skin without evidence of extracutaneous involvement been accepted as primary CBCL. The application of immunohistochemistry and molecular analysis has shown that some cases of cutaneous lymphoid hyperplasia and pseudolymphomas contain a monoclonal population of B cells and are therefore considered true lymphomas. The pathology and classification of this heterogeneous group of lymphoproliferative disorders is reviewed. The main entities comprise marginal zone lymphoma, lymphoplasmacytoid lymphoma (immunocytoma), follicular center cell lymphoma, mantle cell lymphoma, large cell lymphoma (immunoblastic and anaplastic), intravascular lymphomatosis, plasmacytoma, and lymphoblastic lymphoma.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
