Actinic Superficial Folliculitis in a 29-Year-Old Man
Bibliographic record
Abstract
BACKGROUND: Since actinic superficial follicultis was first described in 1985, only three further cases have been published. The characteristics of this disease are monomorphous, superficial, follicular pustules that appear on the back, upper chest, and shoulders annually after the first sun exposure of the year. The lesions resolve on their own within 10 days. Recurrence occurs under similar conditions after a latency period of at least 4 weeks. METHODS: A 29-year-old man presented to our clinic with a 5-year history of an intermittent follicular rash. These eruptions occurred on his back and chest only when he was exposed to the sun, with his shirt off. They developed 24 to 36 hours after the first sun exposure of the year and resolved spontaneously after 5 to 7 days. Photographs of the affected area were impressive, with follicular pustules grouped along his left flank. CONCLUSION: According to our literature search, this is the sixth reported case of actinic superficial folliculitis. This is the first case in which provocative phototesting was done. We review the clinical and pathologic attributes of actinic superficial folliculitis.

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.
