Metastatic Zosteriform Squamous Cell Carcinoma in an Immunocompetent Patient
Bibliographic record
Abstract
BACKGROUND: Although described in several reports of internal malignancies metastasizing to the skin, zosteriform metastases have been reported in only two cases of cutaneous squamous cell carcinoma (SCC). In both of these reports, the patients were immunosuppressed related to renal transplantation. OBJECTIVE: We present a case of an immunocompetent patient with zosteriform metastases originating from a recurrent cutaneous SCC. The lesions were present along the maxillary division of the trigeminal nerve. METHODS: Biopsies from eight lesions were studied using hematoxylin and eosin (H&E) and with immunohistochemistry. RESULTS: Neural involvement was detected in H&E preparations before and during excision of the metastatic nodules by Mohs micrographic surgery. The tumor cells reacted with antikeratin antibodies. The patient has had no evidence of recurrence or metastases 30 months following surgery. CONCLUSION: To our knowledge, this is the first case of cutaneous SCC with zosteriform metastases in a patient with an intact immune system. SCC should be included in the differential diagnosis of lesions presenting in a dermatomal distribution.

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.
