Cutaneous metastases from rectal adenocarcinoma: A case report
Bibliographic record
Abstract
Cutaneous metastases from colorectal cancer are an uncommon but critical finding, typically signaling advanced disease with poor prognosis. This case report describes a 64-year-old woman with a limited past medical history who presented to our outpatient dermatology practice with rapidly spreading erythematous, indurated, and nearly verruciform plaques in the groin, vaginal, and perineal region. Biopsy confirmed metastatic adenocarcinoma of colonic origin, and diagnostic imaging, and colonoscopy revealed stage IV colorectal cancer involving extensive cutaneous, lymphatic, and visceral metastases. Unfortunately, the patient had not received routine colorectal cancer screening, despite a positive family history. Due to extensive disease, palliative radiation was not an option, and systemic chemotherapy was initiated. This case emphasizes the need for awareness of cutaneous metastases as a potential initial presentation of undiagnosed malignancies, the importance of routine colorectal cancer screening, and timely biopsy of suspicious skin lesions for early diagnosis and management.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
